According to the Diagnostic Sessions document1, a diagnostic session is a timed session in which AppDynamics captures transaction snapshots for a business transaction at a more frequent interval that you set. In the session, AppDynamics captures full call graphs for the transactions. A diagnostic session can be triggered manually or automatically based on a health rule violation or a threshold of slow or error transactions. A diagnostic session is always associated with a specific business transaction, not all business transactions configured. Therefore, the correct answer is B. References:

According to the Tiers and Nodes document1, establishing standards for naming applications, tiers, and nodes can help you identify and organize the components of your monitored environment, as well as troubleshoot performance issues and health rule violations. Some of the statements about establishing naming conventions are true:

• Application Tier and Node values can be configured in the application agent startup script: This is true for Java agents, as you can pass values to the agent that will be used as the application, tier, and node name for the system. For example, you can use the -Dappdynamics.agent.applicationName, -Dappdynamics.agent.tierName, and -Dappdynamics.agent.nodeName properties to specify the names in the JVM startup script2.
• Node names must be unique across the entire business application: This is true, as node names are used to identify the individual instances of the application components that are monitored by AppDynamics. Having duplicate node names can cause confusion and errors in the data collection and reporting. Therefore, you should use a naming convention that ensures uniqueness and clarity for each node1.
• Application Tier and Node values can be configured in the controller-info.xml file: This is true for Java agents, as you can also configure the names in the controller-info.xml file, which is located in the /conf directory. The controller-info.xml file contains the properties that define the agent identity and connection to the Controller. You can use the , , and elements to specify the names in the file2.

Some of the statements about establishing naming conventions are false:

• Nodes that reside on different Tiers and different machines (hosts) can have duplicate Node names: This is false, as node names must be unique across the entire business application, regardless of the tier or the host they belong to. Having duplicate node names can cause confusion and errors in the data collection and reporting. Therefore, you should use a naming convention that ensures uniqueness and clarity for each node1.
• Nodes that reside on the same Tier but on different machines (hosts) can have duplicate Node names: This is also false, as node names must be unique across the entire business application, regardless of the tier or the host they belong to. Having duplicate node names can cause confusion and errors in the data collection and reporting. Therefore, you should use a naming convention that ensures uniqueness and clarity for each node1.

Remote Services metrics are the metrics that show the performance and behavior of the external systems that an application interacts with, such as web services, databases, message queues, etc. An AppDynamics administrator can use two locations to view Remote Services metrics: the Tier Dashboard and the Exit Point Metrics. The Tier Dashboard shows the flow map of a tier and its downstream dependencies, including the remote services that the tier calls. The administrator can click on any remote service node on the flow map to see the metrics such as average response time, calls per minute, errors per minute, etc. The Exit Point Metrics show the metrics for all the exit points (remote service calls) of an application, grouped by type, such as HTTP, JDBC, JMS, etc. The administrator can drill down to see the metrics for each exit point, such as the backend name, the tier name, the business transaction name, etc.

To create a user in the web user interface, you need to go to Settings > Groups and Roles > Create User. This option allows you to add a new user account and assign it to one or more groups. You can also specify the user’s name, email, password, and authentication method1 References: 1: Create Users

According to the Database Visibility Supported Environments document1, Database Visibility can monitor the following databases: PostgreSQL, Cassandra, MongoDB, MySQL, SQL Server, Oracle, Sybase ASE, Sybase IQ, and Couchbase. Therefore, the correct answer is A, B, and D. Derby and DB2 are not supported by Database Visibility. References:
