Cisco AppDynamics Associate Performance Analyst 認定 500-420 試験問題 (Q79-Q84):

質問 # 79
Which three data points can be located by drilling down into a JDBC exit call for an Oracle backend? (Choose three.)

正解：A、C、F

解説：
When drilling down into a JDBC exit call for an Oracle backend, AppDynamics provides detailed information about the call. The data points include:
Query type, which can indicate whether it's a SELECT, INSERT, UPDATE, or DELETE statement.
Statement type, which describes the nature of the SQL statement being executed.
Originating node, which identifies the node from which the JDBC call originated.
These data points help in understanding the nature and source of database operations, which can be critical for performance analysis and troubleshooting.

質問 # 80

Refer to the exhibit. Using this heap utilization graph, which method is used to confirm if a memory leak is occurring during a certain time frame?

正解：D

解説：
To confirm if a memory leak is occurring, one should refer to the Tiers and Nodes section of the AppDynamics Controller UI, navigate to the Memory tab, and observe the Heap Utilization over time in relation to the Heap's Current Usage (MB) versus the Maximum (MB) allocated. Consistent growth in heap utilization or an upward trend that does not decrement even after garbage collection indicates a potential memory leak.References:AppDynamics documentation on Memory Leak Detection and Heap Analysis.


質問 # 81
What must a Performance Analyst first configure in order to monitor end-to-end latency performance metrics in AppDynamics?

正解：D

解説：
To monitor end-to-end latency performance metrics, a Performance Analyst must first define the end-to-end latency transaction. This involves configuring the business transactions to include the necessary entry and exit points that capture the complete flow of the transaction, thereby enabling the measurement of the total latency.

質問 # 82
A Performance Analyst needs to send a summary report of specific events every two hours. Which feature can enable this automated report summary?

正解：D

解説：
To send a summary report of specific events every two hours, a Performance Analyst can use the "Email Digests" feature in AppDynamics. This feature allows for the automated aggregation and delivery of pertinent event information at predefined intervals, ensuring stakeholders remain informed about the application's performance and significant events without the need for constant manual monitoring.
References:
AppDynamics documentation on Alerting and Notifications: Details the configuration of email notifications and digests for events and alerts, including scheduling and content customization options.
AppDynamics documentation on Reports: Provides information on various reporting features, including the setup of automated email digests.


質問 # 83
Under the Troubleshooting menu, which option allows viewing of transaction snapshots?

正解：A

解説：
The Slow Response Times option under the Troubleshooting menu provides access to transaction snapshots associated with application performance degradation. From this view, a Performance Analyst can examine individual transaction executions classified as slow, very slow, stalled, or otherwise relevant to response-time analysis.
Transaction snapshots provide detailed diagnostic information such as the Business Transaction name, participating tiers and nodes, execution timeline, call graph, method timings, database calls, remote service calls, errors, and data-collector values. This allows the analyst to determine whether latency originates in application code, a database query, an external service, thread contention, or another downstream dependency.
Health Rule Violations displays warning and critical events generated by health rules, but it is not the primary transaction-snapshot browsing view. War Rooms provide a collaborative troubleshooting workspace for incidents. "Slow and Error Transactions" describes transaction classifications or filtering concepts, but the applicable option under the Troubleshooting menu is Slow Response Times.
Relevant CAAPA Study Guide topics include Troubleshooting Slow Response Times, Transaction Snapshots, User Experience Classification, Call Graph Analysis, Database and Remote Service Calls, and Root-Cause Analysis.
