13. Frage
A Performance Analyst has noticed a significant decrease in an application's workload (calls/min) and is trying to identify the root cause. Which option will give the Performance Analyst insight into the behavior of the affected Business Transactions?
Antwort: E
Begründung:
When a Performance Analyst observes a significant decrease in an application's workload (calls/min), reviewing the "Top Business Transactions by Load" in the Application Dashboard can provide valuable insights. This feature allows the analyst to quickly identify which business transactions have experienced the most significant changes in load, potentially pinpointing the root cause of the overall workload decrease. It offers a focused view of the application's performance, highlighting areas that may require further investigation or immediate action.

14. Frage
What are two options tor sharing snapshot details from the snapshot window? (Choose two.)
Antwort: B,D
Begründung:
To share snapshot details from the snapshot window in AppDynamics, the options to "Download PDF" and
"Export" are typically used. "Download PDF" allows users to generate a PDF report of the snapshot details, providing a convenient and portable format for sharing and review. The "Export" option enables the extraction of snapshot data in various formats (e.g., CSV, XML), facilitating further analysis or sharing with other tools and stakeholders.
References:
AppDynamics documentation on Snapshots: This section covers how snapshots capture detailed performance data for transactions, including how to share and export this information for collaborative analysis.
15. Frage
How can a Business Transaction be permanently deleted?
Antwort: C
Begründung:
To permanently remove a Business Transaction, the analyst must first exclude it from transaction detection and then delete it from the Business Transaction list. Deleting the transaction alone removes its current registration and associated visibility from the Controller, but the Application Agent can rediscover and register it again when matching traffic is observed.
An exclusion rule prevents future requests matching the specified entry point or transaction criteria from being detected as that Business Transaction. After the exclusion is configured and applied, the existing Business Transaction can be deleted safely without being recreated by automatic discovery.
Business Transaction Automatic Cleanup removes stale or inactive transactions according to retention and cleanup criteria; it does not prevent an active transaction from being rediscovered. Merely deleting the transaction from the list is therefore temporary when matching requests continue. Modifying a detection rule may alter transaction classification, but the explicit and reliable method for permanent removal is to exclude the transaction before deleting its existing registration.
Relevant CAAPA Study Guide topics include Business Transaction Detection, Exclude Rules, Automatic Discovery, Business Transaction Registration, Transaction Cleanup, and Business Transaction Management.
16. Frage
The performance impact on the_______would lead a Performance Analyst to limit the duration and frequency of automatic diagnostic sessions.
Antwort: B
Begründung:
The primary concern for a Performance Analyst when considering the impact of automatic diagnostic sessions is the application itself. Intensive diagnostic sessions can be resource-heavy, potentially affecting the application's performance. Therefore, it is often necessary to limit the duration and frequency of these sessions to ensure they do not negatively impact the application's end-user experience.

17. Frage
A Performance Analyst has opened a database collector view. Which tab should be clicked on next to find slow queries?
Antwort: A
Begründung:
When analyzing database performance in AppDynamics, the "Queries" tab within the database collector view is where a Performance Analyst should navigate to find slow queries. This tab presents a list of database queries executed by the application, highlighting those with long execution times, which are potential bottlenecks impacting application performance.
References:
AppDynamics documentation on Database Monitoring: Details the database collector feature, including how to use the Queries tab to identify and analyze slow database queries.
