1. Which two statements are true about gathering functional business and application requirements? (Choose two.)

2. An architect is tasked with designing a greenfield VMware software-defined data center (SDDC) solution that will be used to deliver a private cloud service for a customer.

During the initial meeting with the service owner and business sponsor, the customer has provided the following information to help inform the design:

✑ The solution must initially support the concurrent running of 300 production and 600 development virtual machines.

✑ The production environment should be delivered across two geographically dispersed data centers. The development environment must be vSphere-based but does not have to be deployed on-premises.

✑ The two data centers are connected to each other through multiple diversely routed, high bandwidth and low latency links.

✑ The customer’s server hardware standard document states that all virtual infrastructure hosts must be based on blade architecture only.

✑ The service owner has said that is important to ensure that neither the availability target of 99.5% nor the resource capacity is affected when the operations team completes maintenance activities, such as the monthly software patching and ad-hoc hardware break/fix.

✑ All virtual machine backups must be completed using the existing backup service. The recovery time objective (RTO) for the service is four hours.

✑ The recovery point objective (RPO) of the service is 24 hours.

Given the information from the customer, which two would be classified as assumptions within the design? (Choose two.)

✑ vSphere HA with admission control is disabled

✑ Proactive HA is not supported

✑ Transparent Page Sharing (TPS) is disabled

Virtual Machine Resource Profile 1

✑ Memory sharing techniques should not be used

✑ Virtual machines should be automatically restarted in the event of host failure if resources are available

✑ Automated initial virtual machine placement

Virtual Machine Resource Profile 2

✑ Memory sharing techniques should not be used

✑ Virtual machines should be automatically restarted in the event of host failure regardless of available resources

✑ Automated initial virtual machine placement

Which two recommendations should the architect make for placement of the virtual machines to meet resource profile requirements? (Choose two.)

9. An architect is tasked with planning the design of a new vSphere environment. When commissioned, this environment will be used to migrate an existing set of virtual machines.

An inventory of the existing infrastructure, including configured vCPU, RAM and storage sizes has been provided.

In order for each virtual machine to be migrated, which two data sources with peak and average utilization data are required for sizing? (Choose two.)

10. During a requirements gathering workshop, the customer’s Chief Information Security Office (CISO) provides the following requirements that are pertinent to the design of a new vSphere environment:

✑ All operating system critical patches must be installed within 24 hours of release.

✑ All virtual machine templates must be updated every three months in line with company policy.

Which requirement classification is being gathered for the design documentation?

11. An architect is designing a new VMware software-defined data center (SDDC) that will consist of 100 branch sites connected to a single VMware vCenter Server within the primary data center. To allow for the use of existing automation scripts, there is a requirement to replicate the names of the virtual distributed port groups across all sites. The procurement team purchases licensing and there is no further budget allocated.

Which design decision should the architect make to meet this requirement?

12. An architect will be taking over control of a former Linux server fleet and repurposing the hardware into a new vSphere cluster. The current environment is already connected to the network but the hosts do not have any local disks. Since the fleet hardware is uniform, the architect can use a single ESXi image. All hosts within the cluster have the same CPU and memory capacity.

Which ESXi deployment method should the architect use?

13. Following a company merger, there are two data centers running vSphere environments.

Both data centers are leveraging separate Layer 3 vMotion networks.

Which requirement must be met in order to enable vMotion migration between these locations?

14. An architect is designing a solution for an environment with two types of resource profiles that must be virtualized. The first type consists of Tier 1 virtual machines that are disk I/O intensive, but do NOT require high CPU or memory. The second type consists of Tier 2 virtual machines that require a lower CPU and memory allocation and have minimal disk I/O.

Which design recommendation should the architect make for distributing the resource profiles?

Which two storage settings should be configured for best performance? (Choose two.)

16. A customer requests a review of its current vSphere platform design.

The following information is noted:

✑ There are three different workload profiles for the virtual machines:

✑ [email protected]

✑ Tier-1, Tier-2 and Tier-3 virtual machines are all hosted on a single large vSphere cluster.

✑ The Chief Information Security Officer (CISO) has raised concerns that hosting externally facing applications alongside management tools does not meet internal compliance standards.

✑ The Operations team has raised concerns about Tier-1 virtual machines negatively impacting the performance of vCenter Server.

✑ The Operations lead has stated that management changes have consistently been rejected by application teams.

As a result of the review, which recommendation should the architect make regarding the design of this platform?

17. A new vSphere platform is being created. The platform will host virtual machines that will run management services and line-of-business applications.

What should the architect consider when designing the number and type of clusters required?

18. An architect is designing a solution based on the following information:

✑ Each ESXi host has a single physical NIC with two 10 Gbps ports.

✑ There is a performance-based service-level agreement (SLA) that guarantees 15 Gbps bandwidth for production virtual machines at all times.

✑ There is no budget to purchase additional hardware.

✑ The hardware replacement SLA is based on a delivery agreement of two business days.

Which recommendation for the configuration of vSphere High Availability (HA) should the

architect include in the design?

19. A customer is deploying a new cluster and wants to be able to patch and update two hosts in parallel. The cluster must be able to maintain N+1 resiliency across the remaining hosts while patching activities are performed. The current expected utilization of the platform requires a minimum of two hosts to support all of the virtual machines.

What is the minimum number of hosts the customer will require in the cluster in order to meet the required resiliency level?

20. Which design decision must be included in a design to allow for the deployment of a minimum supported configuration of vCenter High Availability (HA)?
