   An AppDynamics controller is running out of storage space because too many snapshots are being retained. The administrator wants to free up space immediately while preserving the ability to capture new snapshots. What is the most appropriate action?

   • AIncrease the snapshot storage limit to allow more snapshots to be stored
   • BReduce the snapshot capture frequency to slow down the accumulation of new snapshots
   • CDisable snapshot capture entirely to prevent new snapshots from being created
   • DManually purge old snapshots from the controller that are no longer needed

   A support engineer is analyzing a snapshot for a failed login transaction. The snapshot includes a call graph showing the sequence of method invocations, but the engineer needs to see the specific error message returned by the authentication service. Where in the snapshot would this information most likely be found?

   • AIn the call graph, which shows the exact error message as a node label
   • BIn the diagnostic information section, which captures JVM heap dumps and thread dumps
   • CIn the snapshot summary, which lists all captured errors in a separate tab
   • DIn the transaction data section, which includes business data such as return values and error details

   An administrator is configuring snapshot capture for a low-traffic internal application. The team wants to capture snapshots for every execution of a specific transaction to analyze its behavior over time. However, they are concerned about the storage impact of capturing many snapshots. What is the best configuration to balance data collection with storage?

   • ADisable automatic capture and manually trigger snapshots for each execution
   • BEnable snapshot capture for all transactions with a high frequency
   • CSet a low snapshot frequency and a long retention period to keep snapshots for a longer time
   • DSet a high snapshot frequency and a short retention period to keep only recent snapshots

   A snapshot for a slow REST API transaction shows the call graph and transaction data, but the administrator needs to understand why the JVM's garbage collection paused for 2 seconds during the transaction. What type of snapshot data would provide this information?

   • ADiagnostic information, which includes JVM metrics and garbage collection data
   • BCall graph data, which shows method-level timing and external calls
   • CTransaction data, which includes business-level parameters and return values
   • DSnapshot summary, which provides an overview of the transaction's performance
