Snapshots are the detailed records of the execution of a business transaction, including the call stack, the exit points, the errors, and the metrics. To locate snapshots showing slow database response, you can use the following methods:

• Go to the list of snapshots and apply a filter based on slow database response: You can access the list of snapshots from the Business Transaction Dashboard or the Tier Dashboard. You can then apply a filter to show only the snapshots that have a slow database response time, which is the time spent by the business transaction in calling the database. You can specify the minimum and maximum values for the slow database response time, or use the predefined options such as slower than 1 second, slower than 5 seconds, etc. You can also combine this filter with other filters, such as time range, business transaction name, tier name, node name, etc. to narrow down the results1.
• From the flow map, right-click the database icon and select view snapshots: You can access the flow map from the Application Dashboard, the Business Transaction Dashboard, or the Tier Dashboard. The flow map shows the graphical representation of the flow of the business transactions, including the tiers, the nodes, the backends, and the remote services. You can right-click on any database icon on the flow map and select view snapshots to see the list of snapshots that have called that database. You can then sort or filter the snapshots by the database response time column to find the slowest ones2.

The other options are not valid methods to locate snapshots showing slow database response. Going to the dashboard for the database and selecting slowest database calls will show the metrics and the flow map for the database, but not the snapshots. Going to the list of snapshots and selecting analyze for a group of snapshots will show the summary and the comparison of the selected snapshots, but not the database response time.

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 Java Memory Leaks document1, one of the ways to detect and troubleshoot Java memory leaks is to use the Automatic Leak Detection feature on the Memory tab of the Node Dashboard. This feature captures and analyzes the collections that are actively used and growing in size over time, indicating a potential memory leak. You can also drill down into the leaking collections to see the content summary and the access traces that show the code path and the business transactions that access the collection. Therefore, the correct answer is D. Examining the values on the Server tab, configuring Object Instance Tracking, or verifying and adjusting the Memory Monitoring configuration may not directly reveal the source of the memory leak, but they may provide some useful information or metrics to support the diagnosis. References:
