500-425 Exam Dumps : Cisco AppDynamics Associate Administrator (CAAA)

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:

To find the information that shows the current application, tier, and node that the agent currently reports to, you can go to View my settings > AppDynamics Agents section in the Controller UI. This section shows you the list of agents that are connected to the Controller, along with their status, version, application, tier, and node names. You can also filter the list by agent type, status, or application1 References: 1: AppDynamics Agents

To confirm that the agent is communicating properly to the controller, you can use the following methods:

• Check if data is being written to the agent log in /logs. This indicates that the agent is able to send metrics and events to the controller. You can also look for any errors or warnings in the log file that might indicate a connection issue1
• Select Application > Tiers and Nodes > Look for the Node. This shows you the list of nodes that are registered with the controller and their status. You can see if the node is up or down, the agent version, the last reported time, and the machine name2
