Question #4

Which two statements are true when updating the Database Agent? (Choose two.)

A . The Database Agent must be stopped and restarted during the upgrade.
B . If the agent is moved to a new location during the upgrade, the AppDynamics Controller must be reconfigured to reference the new location of the agent.
C . All data collectors created from the previous agent must be migrated to the new agent.
D . Controller-info.xml is the only file that needs to be migrated from the previous agent to the new agent.
E . After the Database Agent is upgraded, the AppDynamics Controller must be restarted.

Correct Answer: AD
AD

Explanation:

According to the Cisco AppDynamics Professional Implementer (CAPI) documents, when updating the Database Agent, you need to follow these steps12:

Stop the agent as described for your specific installation in Start and Stop the Database Agent.

Make a copy of the existing agent directory, <db_agent_home>. Backing up allows you to revert to the previous agent installation if you need to. You can also copy over the controller-info.xml configuration file to the new installation to ensure the agent configuration is maintained.

Install the Database Agent as described for your specific installation in Administer the Database Agent.

Copy the <backup_db_agent_home>confcontroller-info.xml file to the new installation directory, <db_agent_home>conf. To ensure the agent configuration is maintained, copy the <backup_db_agent_home>confcontroller-info.xml file to the new installation directory, <db_agent_home>conf.

Start the new agent. See Start and Stop the Database Agent.

Verify the Database Agent Installation. See Verify the Database Agent Installation.

Therefore, the correct statements are:

The Database Agent must be stopped and restarted during the upgrade. (A) Controller-info.xml is the only file that needs to be migrated from the previous agent to the new agent. (D)

The incorrect statements are:

If the agent is moved to a new location during the upgrade, the AppDynamics Controller must be reconfigured to reference the new location of the agent. (B) This is not true because the controller-info.xml file contains the information about the Controller host, port, account name, access key, and SSL settings. As long as this file is copied to the new agent location, the Controller does not need to be reconfigured.

All data collectors created from the previous agent must be migrated to the new agent. © This is not true because the data collectors are configured on the Controller UI, not on the agent. The agent collects the metrics from the databases and sends them to the Controller. The data collectors do not need to be migrated to the new agent.

After the Database Agent is upgraded, the AppDynamics Controller must be restarted. (E) This is not true because the Controller does not depend on the agent version. The agent and the Controller are compatible as long as they meet the Agent and Controller Compatibility requirements.

Question #6

If using SSL for agent communication with an AppDynamics Controller, it is recommended that agent SSL traffic

A . is encrypted with a 64-bit encryption key
B . is decrypted and then encrypted again at the firewall
C . terminates at a reverse proxy or a load balancer in front of the Controller
D . terminates at the Controller

Monitor.xml file
B . Directory Manitor.xml file Custom-gxtension.xml file
C . Directory
Zip Extension
Monitor.xml file
D . Directory Script file Config.json file

Question #8

An administrator is asked to improve the capacity of an Events Service cluster.

What is the recommended way to add capacity to the cluster?

A . Add a new Events Service cluster to share the load.
B . Add nodes running on machines with identical hardware matching the existing nodes.
C . Add more storage to the master nodes of the cluster.
D . Add more storage to as many of the existing nodes as possible.

Reveal Solution Hide Solution

Correct Answer: B
B

Explanation:

According to the Cisco AppDynamics Professional Implementer (CAPI) documents, the recommended way to add capacity to the Events Service cluster is to add nodes running on machines with identical hardware matching the existing nodes12. This will increase the data storage, replication, and redundancy of the cluster, as well as the processing power for queries. The Events Service cluster is horizontally scalable, so nodes can be added as your data storage requirements grow32. The Events Service must run on dedicated machines with identical directory structures, user account profiles, and hardware profiles1. For heap space allocation, AppDynamics recommends allocating half of the available RAM to the Events Service process, with a minimum of 7 GB up to 31 GB1. Solid-state drives (SSD) can significantly outperform hard disk drives (HDD), and are therefore recommended for production deployments1.

The incorrect options are:

Add a new Events Service cluster to share the load. (A) This is not recommended because it will create additional complexity and overhead for managing multiple clusters and routing data and queries to the appropriate cluster. It will also require more license units to enable analytics on multiple clusters.

Add more storage to the master nodes of the cluster. © This is not recommended because it will not increase the data replication and redundancy of the cluster, nor the processing power for queries. It will also create an imbalance in the cluster, as the master nodes will have more storage than the worker nodes, which may affect the performance and stability of the cluster.

Add more storage to as many of the existing nodes as possible. (D) This is not recommended because it will not increase the data replication and redundancy of the cluster, nor the processing power for queries. It will also create an imbalance in the cluster, as some nodes will have more storage than others, which may affect the performance and stability of the cluster.

Question #10

Which implementation mode should be used when deploying an EUM Server with reverse proxy from a security and performance standpoint in a production environment?

A . Install the EUM Server on the same host as the Controller, behind the reverse proxy.
B . Install the EUM Server on a separate host from the Controller, in front of the reverse proxy.
C . Install the EUM Server on the same host as the Controller, in front of the reverse proxy.
D . Install the EUM Server on a separate host from the Controller, behind the reverse proxy.
