Cisco AppDynamics Associate Performance Analyst 認定 500-420 試験問題 (Q57-Q62):

質問 # 57
An AppDynamics deployment has Business Transaction Lock Down turned on. The company has just added an important service to its application and wants to track this service as a unique Business Transaction. What action is needed to achieve this?

A. Use the Business Transaction Dashboard for the tier-specific All Other Traffic to register the Business Transaction
B. Create a Custom Transaction Match Rule based on the Web Service Name and Operation Name
C. Use live preview to identify the Business Transaction and Register it from there
D. Modify the Automatic Transaction Discovery rule to include the Web Service Name and Operation Name

正解：B

解説：
When Business Transaction Lock Down is enabled in AppDynamics, no new business transactions will be automatically discovered to avoid uncontrolled growth in the number of business transactions. To track a new service as a unique Business Transaction, one needs to create a Custom Match Rule that specifies the criteria for identifying the business transaction. In this case, the Custom Match Rule should be based on the Web Service Name and Operation Name which are the distinguishing characteristics of the new service. This allows for the precise identification and monitoring of the service within the AppDynamics platform.
References: AppDynamics documentation on Business Transaction configuration and Custom Match Rules.

質問 # 58
Which tab within the Application Dashboard displays performance trends for each of Snapshots, Average Response Time, and Events within one central view?

A. Application Flow Map
B. Network Dashboard
C. Dashboard
D. Events
E. Transaction Score

正解：E

解説：
The Transaction Score tab within the Application Dashboard is designed to display performance trends across various metrics including Snapshots, Average Response Time, and Events. It gives a comprehensive view of the transaction performance, providing a score that reflects the health and reliability of transactions over time.

質問 # 59

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?

A. In metric browser go through Application Infrastructure > Hardware Resources and select Memory Total (MB) and Used (MB)
B. Refer to the Tiers and Nodes section and into the Memory tab and visualize Heap Utilization (%) and Heap Current Usage (MB) Vs Max (MB)
C. In metric browser go through Application Infrastructure > Hardware Resources > Memory Total (MB) and Swap Used (MB)
D. Refer to the Tiers and Nodes section and into the JMX tab and select JVM > Memory > Heap > Max Available (MB) and Current usage (MB)

正解：B

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 # 60
Which built-in scheduled report Includes load, response time, and error graphs?

A. User Experience: Browser Apps
B. Application Health Report
C. Dashboard Report
D. All Application Summary

正解：B

解説：
The "Application Health Report" is a built-in scheduled report in AppDynamics that includes vital metrics such as load, response time, and error graphs. This report provides a comprehensive overview of the application's health and performance, making it an essential tool for Performance Analysts to regularly review and share with stakeholders to ensure the application meets performance standards and user expectations.
References:
AppDynamics documentation on Reporting: Covers the types of reports available within AppDynamics, including the Application Health Report, detailing its contents and how to schedule and customize it.
AppDynamics documentation on Application Performance Management: Provides an overview of key performance indicators and metrics critical for assessing application health, many of which are included in the Application Health Report.

質問 # 61
Which two roll-up types can be configured for an Information Point? (Choose two.)

A. Sum
B. Count
C. Max
D. Average

正解：A、D

解説：
An Information Point custom metric can be configured with the roll-up types Average and Sum. The selected roll-up determines how values reported by repeated executions of the monitored class and method are aggregated during each metric reporting interval.
Average calculates the mean of all collected values within the interval. This is appropriate for measurements such as average item-processing time, average order value, or another numeric value where typical behavior is the primary concern.
Sum adds all collected values reported during the interval. It is appropriate for cumulative business or operational measurements, such as the total number of items processed, total transaction value, or total quantity handled by the instrumented method.
Max is not one of the configurable Information Point roll-up choices in this context. Although maximum values can appear in other AppDynamics metric-analysis scenarios, they are not selected as an Information Point custom-metric roll-up type. Count is represented separately through invocation-frequency metrics such as Calls per Minute rather than as the configured roll-up method for the collected numeric value.
Relevant CAAPA Study Guide topics include Information Points, Custom Metrics, Metric Aggregation, Average Roll-Up, Sum Roll-Up, Method Invocation Monitoring, and Calls per Minute.
