Question #1

In order to give Consumers the ability to modify attributes, what should the Blueprint creator implement in the design?

A . Custom actions
B . eScript task with custom macros
C . Runtime variables
D . HTTP task with built-in macros

Correct Answer: C
C

Explanation:

Runtime variables are variables that can be modified by the Consumer during the deployment of a Blueprint or after the deployment is complete. They allow the Consumer to customize the attributes of the infrastructure and applications according to their needs. Runtime variables can be defined in the Blueprint settings or in the Blueprint YAML file. They can also be used in the Blueprint tasks to pass dynamic values to the scripts or commands. Runtime variables can be of different types, such as text, number, boolean, list, or password. They can also have default values, constraints, and descriptions to guide the Consumer.

Question #2

Refer to the exhibit.

The Playbook is designed to execute a script, in order to fix a known problem in the application.

However, it keeps failing.

Why is this Playbook continuing to fail?

A . Slack configuration should be reviewed.
B . The script is incorrect.
C . The Playbook actions are in the wrong order.
D . Not enough storage space in order to take a snapshot.

Reveal Solution Hide Solution

Correct Answer: C
C

Explanation:

In the context of Nutanix Multicloud Automation (NCP-MCA), the order of actions in a playbook is crucial for its successful execution. In this case, the playbook is designed to execute a script to fix a known problem in an application but keeps failing because it attempts to power off the VM and take a snapshot before executing the script. The correct order should be to execute the script first, then power off the VM if necessary, and finally take a snapshot.

Question #3

Which action should an administrator use to request a static IP address from an IPAM solution?

A . Profile
B . Pre-create
C . Guest Customization
D . Create

Reveal Solution Hide Solution

Correct Answer: B
B

Explanation:

When integrating with an IP Address Management (IPAM) solution within Nutanix Calm, an administrator would use a ‘Pre-create’ task to request a static IP address. This task is performed before the actual creation of the VM, ensuring that the IP address is allocated and can be assigned during the VM’s creation process. Profiles (A) are used to define deployment environments, Guest Customization (C) is used for configuring the OS settings, and Create (D) is typically the task for provisioning the actual VM, not for requesting an IP.

Question #4

Refer to the exhibit.

What needs to be done in order to enable the developer to complete this requested task? (Choose two.)

A . Create AWS and Azure Providers
B . Add the Providers to the Project
C . Enable Environment for AWS and Azure
D . Upgrade Calm to version 3.2.x

Reveal Solution Hide Solution

Correct Answer: AB
AB

Explanation:

In order to enable the developer to complete the requested task, AWS and Azure Providers need to be created (Option A). This is because, in the context of Nutanix Calm, providers are integrations with public and private cloud infrastructures. The developer is trying to deploy an application on AWS and Azure clouds but currently only has Nutanix as a configured provider. After creating the providers, they need to be added to the project (Option B) so that applications can be deployed on them. Option C is incorrect because environments are not required for multicloud deployments. Option D is also incorrect because Calm version 3.2.x is not relevant to the question.

Question #6

An administrator wants to be alerted when production VMs become idle. The VMs will be determined to be idle when CPU usage is lower than 5% for more than 5 minutes. All affected VMs are categorized as Environment: Production, since they have Flow microsegmentation rules.

What should the administrator do to satisfy this requirement?

A . Create an alert for all VMs, create a Playbook with this alert as the trigger and send an email as the action.
B . Create an alert for VMs in the correct category, create a Playbook with this alert as the trigger > take a snapshot > send an email as the action.
C . Create an alert for all VMs, create a Playbook with this alert as the trigger > reduce 1 CPU > send an email as the action.
D . Create an alert for VMs in the correct category, create a Playbook with this alert as the trigger and send an email as the action.

Reveal Solution Hide Solution

Correct Answer: D
D

Explanation:

To create an alert for idle VMs, the administrator needs to specify the following parameters: Scope: Select the category value Environment: Production to filter the VMs that are affected by the alert.

Metric: Select CPU Usage (%) as the metric to monitor the VMs’ CPU utilization.

Condition: Select Less Than as the operator and enter 5 as the threshold value to define the idle state.

Duration: Enter 5 as the duration value and select Minutes as the unit to set the time period for the idle state.

To create a Playbook with the alert as the trigger, the administrator needs to do the following steps:

Name: Enter a descriptive name for the Playbook, such as Idle VM Alert.

Trigger: Select Alert as the trigger type and choose the alert that was created for idle VMs.

Action: Select Email as the action type and enter the recipient email address, subject, and message for the notification.

The Playbook will run whenever the alert is triggered and send an email to the administrator

informing them about the idle VMs.

Question #7

A developer has a Development Blueprint that performs the following high level items:

Creates a Windows and Ubuntu Server.

Installs IIS on Windows

Installs MySQL on Ubuntu

As part of Development, there is a need for an Operator to restart IIS Services for troubleshooting purposes.

How should the developer add this functionality to the Blueprint?

A . Add an Execute Task in the Restart Action of the Application Profile.
B . Add an Execute Task in the Restart Action of the Windows/IIS Service.
C . Add a Delay Task in the Restart Action of the Windows/IIS Service.
D . Create an Endpoint for the IIS server and a Runbook that restarts the service.

Reveal Solution Hide Solution

Correct Answer: B
B

Explanation:

The Restart Action of a Service allows the developer to define custom tasks that will be executed when the service is restarted. An Execute Task can run any script or command on the target VM, such as restarting the IIS service. This way, the Operator can use the Self-Service Portal to restart the service without logging into the VM or using another tool.

Question #8

An administrator receives the following error while running a script through Calm on VM:

Which two conditions could cause this issue? (Choose two.)

A . The VM port is not allowed by the firewall.
B . The credentials have insufficient permissions.
C . The VM is still in the boot process.
D . There is an error in the script.

Reveal Solution Hide Solution

Correct Answer: A, B
A, B

Explanation:

The error “Connection refused” can occur due to several reasons but in the context of running a script through Calm on VM, it is most likely caused by firewall restrictions or insufficient permissions. Option A suggests that the VM port is not allowed by the firewall, meaning that the firewall settings are preventing the connection. This could be because specific ports needed for the script to run are being blocked. Option B indicates that the credentials have insufficient permissions, meaning that the user or system trying to execute the script does not have the necessary permissions to establish a connection. Option C is unlikely because the VM should be ready before the script is executed. Option D is possible but not specific enough to explain the connection issue.

Question #9

When creating a blueprint, which Pre-create and Post-delete tasks are valid?

A . Create, Start, Stop, Delete
B . Execute, Set variable, HTTP, Delay
C . Create, Start, Stop, Soft Delete
D . Execute, Set variable, API, Delay

Reveal Solution Hide Solution

Correct Answer: B
B

Explanation:

Pre-create and Post-delete tasks are actions that can be performed before creating or after deleting a blueprint deployment. They can be used to integrate with external systems, set variables, or add delays. The valid tasks are Execute, Set variable, HTTP, and Delay. Create, Start, Stop, and Delete are not valid tasks, as they are part of the deployment lifecycle, not the pre-create or post-delete actions.

Question #11

A blueprint was developed for deploying a standard 3-tier hosting environment for a company’s applications. The blueprint includes a load balancer, multiple web servers, a database server, and a small test application.

During testing of the blueprint, the application fails to connect to the database. The cause is found to be the database software is still installing when the application starts.

Which method most efficiently prevents the application from starting before the database?

A . Use a local install instead of downloading
B . Create a loop to retry connection
C . Create a service dependency
D . Use a sleep statement in a start script

Reveal Solution Hide Solution

Correct Answer: C
C

Explanation:

A service dependency is a feature of Nutanix Calm that allows you to define the order of execution and the conditions for starting and stopping services in a blueprint. By creating a service dependency between the application and the database, you can ensure that the application will not start until the database is fully installed and ready. This avoids the need for manual intervention or inefficient workarounds like loops or sleep statements.

Question #12

Which Prism Central setting must first be configured in order to add users to a Project?

A . HTTP Proxy
B . Authentication Directory
C . Pulse
D . Local User Role Mapping

Reveal Solution Hide Solution

Correct Answer: B
B

Explanation:

In order to add users to a Project, the Prism Central administrator must first configure an Authentication Directory. This is a service that provides user authentication and authorization for Prism Central, such as Active Directory or OpenLDAP. By configuring an Authentication Directory, the administrator can enable users to log in to Prism Central using their existing credentials and assign them roles and permissions based on their group membership. The administrator can also create local user accounts for users who do not belong to any Authentication Directory.

Question #13

A customer is trying to deploy an application with Calm and receives this error for a Linux VM:

What is the cause of this error within the blueprint?

A . Connection section has a network adapter selected for the Address box in Connection section.
B . Connection section has no network adapters selected for the Address box in Connection section.
C . Connection Type has a protocol selected.
D . Connection Type has no protocol selected.

Reveal Solution Hide Solution

Correct Answer: B
B

Explanation:

In the context of deploying an application with Calm, if a customer receives an error for a Linux VM, it could be due to the absence of network adapters selected for the Address box in the Connection section within the blueprint. This means that there is no specified network connection for the VM, leading to a failure in script execution.

Question #14

Which method will result in unique names per VM when scaling out a Service in a Calm Blueprint?

A . Guest OS customization using sysprep contains <ComputerName>@@{name}@@</ComputerName>.
B . Service VM Name field contains the macro variable @@{calm_array_index}@@.
C . Call an external Python eScript that uses an IPAM API to register the VM name in DNS.
D . Set the VM Name field to allow user edits at launch so the user can enter a custom value at launch.

Reveal Solution Hide Solution

Correct Answer: B
B

Explanation:

The correct method to result in unique names per VM when scaling out a Service in a Calm Blueprint is to use the macro variable @@{calm_array_index}@@ in the Service VM Name field (Option B). This variable will append a unique index number to each VM name based on the scale-out count. For example, if the Service VM Name is MyAppVM-@@{calm_array_index}@@ and the scale-out count is 3, the resulting VM names will be MyAppVM-0, MyAppVM-1, and MyAppVM-2. Option A is incorrect because the <ComputerName> tag in the sysprep file will only affect the hostname of the guest OS, not the VM name in the cloud provider. Option C is incorrect because calling an external Python eScript to register the VM name in DNS will not change the VM name in the cloud provider either. Option D is incorrect because setting the VM Name field to allow user edits at launch will require manual input from the user for each VM, which is not scalable or automated.

Question #17

During the deployment of a multi-step Blueprint, a failure is encountered. The administrator corrected the failed step and saved the Blueprint.

What should the administrator do next?

A . Delete the failed application and Launch a new application.
B . Soft Delete the failed application and Launch a new application.
C . Use Continue in the failed application to retry.
D . Upon clicking Save the Blueprint task will be retried automatically.

Reveal Solution Hide Solution

Correct Answer: C
C

Explanation:

If a Blueprint deployment fails, the administrator can use the Continue option in the Self-Service Portal to resume the deployment from the point of failure. This option will retry the failed task and continue with the remaining tasks in the Blueprint. The administrator does not need to delete the application or launch a new one, as this would waste time and resources. Saving the Blueprint will not automatically retry the task, as the Blueprint is only a template for the deployment.

Question #18

An administrator has a vendor-provided script that must be run at 9 am every Saturday on a Linux application VM.

The administrator currently has a playbook that has a Time trigger and a VM SSH action to execute the script. However, the administrator has received a request to have the output of the script emailed to the application team when it is executed.

What is the easiest way to satisfy this request?

A . Modify the script to include a function to format the output of the script and email the output to the desired address.
B . Add an Email action to the end of the existing playbook and use the {{action [index].response_body}} parameter in the Message field.
C . Direct the output of the script to a file and use the Send Email with Payload action at the end of your existing playbook.
D . Add an Email action to the end of the existing playbook and use the {{action[index] .stdout}} parameter in the Message field.

Reveal Solution Hide Solution

Correct Answer: D
D

Explanation:

The easiest way to satisfy the request is to add an Email action to the end of the existing playbook and use the {{action[index] .stdout}} parameter in the Message field. This way, the administrator does not need to modify the script or create a file to store the output. The {{action[index] .stdout}}

parameter will capture the standard output of the previous action, which is the VM SSH action that executes the script. The Email action will then send the output as the message body to the specified recipients.

Question #19

An administrator has been tasked with creating a multicloud, three-tier application using Calm.

The application needs to consist of:

A MongoDB backend database

A NodeJS Javascript runtime environment

An NGINX webserver

The administrator has access to an AWS account, as well as a locally hosted Nutanix cluster. The three parts of the application should be fully redundant, and be able to tolerate either a cloud provider outage, or a local Nutanix cluster outage.

What is the most appropriate solution the administrator should choose in order to meet the requirements?

A . Create a Calm blueprint with MongoDB, Node/S, and NGINX VMs running on Nutanix, as well as an NGINX server running in AWS on US-WEST-1 and US-EAST-1.
B . Create a Calm blueprint with MongoDB, Node/S and NGINX VMs running on Nutanix, and a separate blueprint for MongoDB, NodeJS, and NGINX running in AWS on US-WEST-1 and US-EAST-1.
C . Create a Calm blueprint with MongoDB, NodelS, and NGINX VMs running on Nutanix, as well as MongoDB, NodeJS, and NGINX servers running in AWS on US-WEST-1 and US-EAST-1.
D . Create a Calm blueprint with MongoDB, NodelS, and NGINX VMs running on Nutanix, then manually create three EC2 instances for MongoDB, NodeJS and NGINX in AWS running on US-WEST-1 and
US-EAST-1.

Reveal Solution Hide Solution

Correct Answer: C
C

Explanation:

This solution meets the requirements of creating a multicloud, three-tier application using Calm. It ensures that each tier of the application has a redundant copy running on both Nutanix and AWS, and that the application can tolerate either a cloud provider outage or a local Nutanix cluster outage. The other options do not provide full redundancy for each tier, or require manual intervention to create the AWS instances.

What are two valid trigger types available for executing Playbooks? (Choose two.)

A . Manual
B . Alert
C . Report
D . Audit

Reveal Solution Hide Solution

Correct Answer: A, B
A, B

Explanation:

Playbooks are a collection of tasks that can be executed on demand or based on a trigger. There are two types of triggers available for executing Playbooks: manual and alert. A manual trigger allows you to run a Playbook on demand from the Prism Central UI or the Calm API. An alert trigger allows you to run a Playbook automatically when a specific alert is generated by Prism Central or a third-party system. Report and audit are not valid trigger types for Playbooks.

Question #22

An administrator needs to configure a Prism Central automation task to be notified if production VMs

exceed the CPU threshold of 70%.

How can this be achieved?

A . Create an NCC alert based on performance data.
B . Create an Alert policy for Category Env:Production.
C . Create an Alert policy for all VMs.
D . Create a script from the Guest OS for the alert.

Reveal Solution Hide Solution

Correct Answer: B
B

Explanation:

To create a custom alert policy, the administrator needs to specify the entity type, the impact, the severity, the condition, and the notification method. In this case, the entity type is VM, the impact is performance, the severity is warning, the condition is CPU usage > 70%, and the notification method is email. Additionally, the administrator can use categories to filter the entities that are affected by the alert policy. By selecting the category Env:Production, the administrator can limit the alert policy to only apply to the production VMs.

Question #23

An administrator needs to create a Playbook to be notified when VMs are deleted.

Which X-Play Trigger would satisfy this task?

A . Alert
B . Audit
C . Event
D . Time

Reveal Solution Hide Solution

Correct Answer: C
C

Explanation:

An X-Play Trigger is a condition that initiates a Playbook. There are four types of X-Play Triggers: Alert, Audit, Event, and Time1. An Alert Trigger is based on a Prism alert, such as a VM power state change or a disk failure. An Audit Trigger is based on a Prism audit entry, such as a user login or a cluster operation. An Event Trigger is based on a Prism event, such as a VM creation or deletion. A Time Trigger is based on a schedule, such as daily, weekly, or monthly2. In this scenario, the administrator needs to create a Playbook to be notified when VMs are deleted. Therefore, the appropriate X-Play Trigger would be an Event Trigger, since VM deletion is a Prism event.

When a developer launches the created Blueprint within the Blueprint Editor, the application gets deployed correctly. However, when the Blueprint is launched via Marketplace, it gets a check login error.

What is causing this issue?

A . Prism Central can’t communicate with Active Directory.
B . The SSH key within the user’s laptop is not valid.
C . User is not authorized to launch Blueprints.
D . The credential in the Project Environment is invalid.

Reveal Solution Hide Solution

Correct Answer: D
D

Explanation:

When a Blueprint is launched via Marketplace, it uses the credential that is configured in the Project Environment. If the credential is invalid, the Blueprint deployment will fail with a check login error. To fix this issue, the developer needs to verify and update the credential in the Project Environment and ensure that it has the required permissions to access the target infrastructure and applications.

Question #30

What two pieces of information can an administrator obtain from Plays? (Choose two.)

A . Host where the action runs
B . Start time and end time of each action
C . Execution result status
D . CVM IP where the alert was triggered

Reveal Solution Hide Solution

Correct Answer: A, C
A, C

Explanation:

Plays are event-driven automation workflows that can be triggered by alerts, schedules, or manual actions. They consist of one or more actions that run on specified hosts or clusters. An administrator can obtain the following information from Plays:

Host where the action runs: Each action in a Play can be configured to run on a specific host or cluster, or on the host or cluster where the alert was triggered. The administrator can view the host or cluster name for each action in the Play details page.

Execution result status: Each action in a Play has an execution result status that indicates whether the action was successful, failed, skipped, or cancelled. The administrator can view the status for each action in the Play details page, as well as the overall status of the Play. The other options are incorrect because:

Start time and end time of each action: Plays do not show the start time and end time of each action, only the duration of the action. The administrator can view the duration for each action in the Play details page, as well as the overall duration of the Play.

CVM IP where the alert was triggered: Plays do not show the CVM IP where the alert was triggered, only the host or cluster name where the alert was triggered. The administrator can view the host or cluster name for the alert in the Play details page.

Question #31

An administrator is configuring Playbooks and is concerned about adding or reducing CPU and memory resources to VMs.

Which two prerequisites should an administrator take into consideration when configuring the Playbooks? (Choose two.)

A . CPU can be added to a powered on VM if the guest OS supports it
B . VM must be powered off to add CPU
C . VM must be powered off to reduce memory
D . Memory can be removed from a powered on VM if the guest OS supports it

Reveal Solution Hide Solution

Correct Answer: A, D
A, D

Explanation:

When configuring Playbooks to automate the scaling of CPU and memory resources for VMs, the administrator should consider the following prerequisites:

CPU can be added to a powered on VM if the guest OS supports it. This is also known as hot-plug CPU. The administrator should check the compatibility of the guest OS and the hypervisor before enabling this feature. For example, Windows Server 2019 supports hot-plug CPU on AHV, ESXi, and Hyper-V, but not on XenServer1.

Memory can be removed from a powered on VM if the guest OS supports it. This is also known as hot-unplug memory. The administrator should check the compatibility of the guest OS and the hypervisor before enabling this feature. For example, Linux supports hot-unplug memory on AHV, ESXi, and XenServer, but not on Hyper-V2.

VM must be powered off to add CPU if the guest OS does not support hot-plug CPU. This is also known as cold-plug CPU. The administrator should plan for the downtime required to power off and power on the VM after adding CPU.

VM must be powered off to reduce memory if the guest OS does not support hot-unplug memory. This is also known as cold-unplug memory. The administrator should plan for the downtime required to power off and power on the VM after reducing memory.

Question #32

An end user for an application that has been assigned the Consumer role within the project has noticed multiple issues with a blueprint that need to be addressed. The decision has been made to bring the end user onto the team to be able to modify the blueprints for this project.

Using the concept of least privilege, what role should the end user be assigned?

A . Developer
B . Project Admin
C . Consumer
D . Operator

Reveal Solution Hide Solution

Correct Answer: A
A

Explanation:

The Developer role is the most appropriate role for the end user who needs to modify the blueprints for the project. The Developer role allows the user to create, edit, and delete blueprints and runbooks within the project, as well as launch and manage applications from the Marketplace. The Developer role does not have the privileges to create or manage projects, users, roles, or categories, which are reserved for the Project Admin role. The Consumer role only allows the user to launch and manage applications from the Marketplace, but not to modify the blueprints or runbooks. The Operator role allows the user to monitor and manage the infrastructure and applications within the project, but not to create or edit the blueprints or runbooks.

D . Number of Template VMXNET3 components should be equal to the number of Virtual e1000 adapters configured.

Reveal Solution Hide Solution

Correct Answer: B
B

Explanation:

The error message in the exhibit indicates a mismatch between the number of network settings and the number of NICs on the VM. This is a common validation error when saving Calm Blueprints for VMware, where it is essential to ensure that these configurations match to avoid issues with VM deployment and operation1.

Reference: 1: Nutanix NCP-MCA Certification Exam Sample Questions2

Question #34

A company has a business-critical VM. The VM Utilization of CPU and memory differs from time to time, but can never be allowed to run out of resources. The administrator also wants to make sure that the VM is not over provisioned when not needed.

The administrator determines these requirements that have been validated and automated in a test environment should also apply for the production environment:

VCPU needs to be added when CPU Utilization been over 80% for 15 minutes.

Memory needs to be increased by 4 GB when utilization reaches 80%.

Return of over-allocated resources must not affect other business applications.

What can the administrator do with the least amount of effort to make sure the VM is always performant and returns resources when not required?

A . Clone and adjust the system-created playbooks
B . Import the playbook and adjust the values
C . Create a blueprint based on requirements
D . Create a task based on requirements

Reveal Solution Hide Solution

Correct Answer: B
B

Explanation:

The easiest way to automate the VM utilization and resource allocation is to use a playbook that has been already tested and validated in a test environment. A playbook is a collection of actions that can be triggered by events or schedules to perform various tasks on the Nutanix platform. By importing the playbook from the test environment to the production environment, the administrator can save time and effort in creating a new playbook from scratch. The administrator only needs to adjust the values of the playbook parameters, such as the VM name, the CPU and memory thresholds, the VCPU and memory increments, and the notification settings, to match the production environment. The playbook can then be executed manually or automatically based on the desired frequency and conditions.

Question #36

Where should an administrator check why a Playbook failed to grow the memory of a VM?

A . VM Details in Prism Element
B . Plays dashboard in Prism Central
C . VM Details in Prism Central
D . Plays dashboard in Prism Element

Reveal Solution Hide Solution

Correct Answer: B
B

Explanation:

The Plays dashboard in Prism Central provides a centralized view of all the Playbooks that have been executed across the clusters registered with Prism Central. It shows the status, duration, and output of each Playbook run, as well as the details of the triggers, targets, and actions involved. An administrator can use the Plays dashboard to troubleshoot why a Playbook failed to grow the memory of a VM by checking the error messages, logs, and output of the Playbook run. The other options are not the correct places to check for Playbook failures, as they do not provide the same level of information and visibility as the Plays dashboard.

Question #37

An administrator is trying to delete a category, but the option is greyed out.

Which two conditions could be causing this issue? (Choose two.)

A . The category is system defined.
B . The category is assigned to powered-on VMs.
C . The category is part of a flow policy.
D . The category is user defined.

Reveal Solution Hide Solution

Correct Answer: A, C
A, C

Explanation:

Categories are key-value pairs that you can use to tag and filter entities in Nutanix. There are two types of categories: system defined and user defined. System defined categories are built-in and cannot be deleted. User defined categories are created by the administrator and can be deleted if they are not used in any policy. Policies are rules that apply actions or restrictions to entities based on their categories. Flow policies are policies that control the network security and visibility of VMs. If a category is part of a flow policy, it cannot be deleted unless the policy is removed or modified. Therefore, the two conditions that could prevent an administrator from deleting a category are: the category is system defined, or the category is part of a flow policy.

Question #40

A director would like to have an up to date Cluster Efficiency Summary report emailed on the first of every month to keep management up to date on how the cluster is being utilized.

How could a playbook be configured to satisfy this request with the least human interaction?

A . Manual Trigger > Wait Until Day of Month > Generate Report > Email
B . Manual Trigger > Generate Report > Email
C . Report Trigger > Wait Until Day of Month > Email
D . Time Trigger > Generate Report > Email

Reveal Solution Hide Solution

Correct Answer: D
D

Explanation:

A time trigger is a type of playbook trigger that allows the user to specify a schedule for running a playbook. This trigger is useful for automating tasks that need to be performed periodically or at a specific time. A manual trigger requires the user to initiate the playbook execution manually, which is not ideal for a recurring task. A report trigger is a type of playbook trigger that allows the user to run a playbook when a specific report is generated. However, this trigger does not guarantee that the report will be generated on the first of every month, as it depends on the report settings. A wait until day of month action is a type of playbook action that pauses the playbook execution until a specified day of the month. This action is unnecessary if the playbook already has a time trigger that specifies the desired schedule.

Question #41

An Application team has provided an administrator the following high level requirements for infrastructure they require:

5 Application VMs

2 Database VMs

2 Web VMs

Which two pieces of information are needed, at a minimum, to effectively automate the scaling of the environment? (Choose two.)

A . SLA uptime of the application
B . Steady state resource utilization
C . Expected resource utilization under load
D . If the application needs to be highly available

Reveal Solution Hide Solution

Correct Answer: B C
B C

Explanation:

To effectively automate the scaling of the environment, the administrator needs to know the steady state resource utilization and the expected resource utilization under load of the application, database, and web VMs. These two pieces of information will help the administrator to define the scaling policies, thresholds, and actions for the blueprint service that deploys the infrastructure. The administrator can use the Self-Service feature of Nutanix Multicloud Automation to create a blueprint service that can scale up or down based on the resource utilization metrics. The administrator can also use the Runbook feature to automate the scaling actions using scripts or APIs. The other options are incorrect because:

SLA uptime of the application: This is not a piece of information that is needed to automate the scaling of the environment. The SLA uptime of the application is a performance indicator that measures the availability and reliability of the application. The administrator can use the X-Play feature of Nutanix Multicloud Automation to create event-driven playbooks that can trigger actions based on alerts or schedules to ensure the SLA uptime of the application.

If the application needs to be highly available: This is not a piece of information that is needed to automate the scaling of the environment. The high availability of the application is a design consideration that affects the architecture and configuration of the infrastructure and the application. The administrator can use the Projects feature of Nutanix Multicloud Automation to create projects that can define the availability domains, networks, and storage for the infrastructure and the application.

Explanation:

According to the Nutanix Multicloud Automation Administration (NMCAA) course1, one of the prerequisites for using X-Play to automate tasks on VMs is to have SSH enabled and configured on the target VMs. This allows X-Play to connect to the VMs and execute commands or scripts remotely. If the SSH service is not running on the VMs, then X-Play will fail to connect and perform the actions, resulting in the error message shown in the exhibit. The other options are not likely to cause this error, as they are either unrelated to X-Play (A and B) or not required for X-Play to work ©.

Question #47

An administrator wants to create a blueprint for a development environment that uses an existing on-premise GitLab repository. Every new development environment requires a new user in the GitLab repo.

Which two tasks should the administrator perform within a Calm blueprint to automate this process? (Choose two.)

A . Create an HTTP pre-create task to create the user in GitLab via REST API.
B . Create runtime-editable variables for user and password in the blueprint.
C . Add a task within the service in order to ask for user and password at runtime.
D . Create a task script in order to login with ssh to GitLab and create a random user and password.

Correct Answer: A, B
A, B

Explanation:

To automate the creation of a new user in GitLab for every new development environment, the administrator should perform the following tasks within a Calm blueprint:

Create an HTTP pre-create task to create the user in GitLab via REST API. This task will send an HTTP request to the GitLab server with the user information and credentials, and receive a response with the user ID and status. The administrator can use the response to verify the user creation and store the user ID as a variable for later use.

Create runtime-editable variables for user and password in the blueprint. These variables will allow the administrator to specify the user name and password for the new GitLab user at the time of launching the blueprint. The variables can be passed as parameters to the HTTP pre-create task and used in the REST API call.

The other two options are not correct because:

Adding a task within the service to ask for user and password at runtime is redundant and unnecessary, as the runtime-editable variables can already provide this functionality.

Creating a task script to login with ssh to GitLab and create a random user and password is not a good practice, as it exposes the GitLab server to security risks and does not use the REST API that GitLab provides for user management.

Question #48

An administrator is notified of changes made to VMs on an AHV cluster and wants to verify the changes inside of a Calm application.

Where should the administrator check for synchronized changes between Prism Central and Calm?

A . On the Prism Central Tasks page
B . On the Audit tab of the Calm application
C . On the Environments tab of the Calm project
D . On the Overview tab of the Calm application

Reveal Solution Hide Solution

Correct Answer: B
B

Explanation:

The Audit tab of the Calm application shows the history of actions performed on the application, such as create, update, delete, launch, stop, etc. It also shows the status of the synchronization between Prism Central and Calm, which indicates if the changes made to the VMs on the AHV cluster are reflected in the Calm application. The administrator can check the Audit tab to verify the changes and troubleshoot any issues with the synchronization.

Question #49

An administrator needs to add AWS as a usable destination for application deployments.

Where would the administrator perform the task?

A . Marketplace
B . Projects
C . Blueprints
D . Providers

Reveal Solution Hide Solution

Correct Answer: D
D

Explanation:

The administrator needs to add AWS as a provider in Calm. A provider is a cloud platform or infrastructure that hosts the application VMs or services. Calm supports various providers such as Nutanix, AWS, Azure, GCP, VMware, and Kubernetes. To add a provider, the administrator needs to go to the Providers page in the Calm UI and click on the +Create Provider button. Then, the administrator needs to select the AWS provider type and enter the required information such as name, access key, secret key, and regions.

Question #50

Refer to the exhibit.

A Blueprint fails on executing a check-login task against a Windows 2016 VM and displays the error shown in the exhibit. The administrator is using a SSH key-based credential to authenticate the task.

What should the administrator change to resolve the issue?

A . Increase the retries to allow for the task to complete.
B . Change to password authentication credential.
C . Ensure the private key for the credential is correct.
D . Modify the timeout to give the task longer to complete.

Reveal Solution Hide Solution

Correct Answer: C
C

Explanation:

The error message “Authentication by <Credential_type> failed” typically indicates an issue with the authentication credentials being used. Since the administrator is using SSH key-based credential to authenticate, it’s essential to ensure that the private key associated with this credential is correct and accessible. If there’s an issue with the private key, such as it being incorrect or inaccessible, authentication will fail. Increasing the retries or modifying the timeout will not help if the credential is invalid. Changing to password authentication credential may work, but it’s not the best option as it may compromise security and require additional configuration.
