500-420 Online Practice Questions and Answers

Correct Answer: A

The performance pattern outside of business hours on 6/16/18 that would be of most interest to a Performance Analyst is the elevated response time, as indicated on 6/19/18. This is because it shows a significant spike in response time,

which could indicate a performance issue that needs to be addressed. Anomalies in response time can often be more indicative of underlying problems than changes in call volume, especially when they occur outside of expected peak

periods.

Correct Answer: A

If a Performance Analyst has an urgent need to gather more data for an ongoing issue, they should enable Development Level Monitoring. This monitoring level increases the amount of detailed diagnostic data collected by the agent, such as

snapshots and transaction traces, which can provide deeper insights into the issue at hand.

Correct Answer: A

To identify if automatic remediation actions have been taken for a health rule violation in AppDynamics, a Performance Analyst should expand the "Description" field of the health rule violation event. This section will provide details on the actions executed as part of the automatic remediation process. These details help analysts understand the steps taken by the system to mitigate the issue without manual intervention.References:AppDynamics documentation on Health Rule Violations and Automated Actions.

Correct Answer: BC

Information Points in AppDynamics are designed to collect custom metrics that are specific to the business or code aspects of an application. They can capture Business Metric Data, which pertains to the performance metrics that directly

impact business processes, and Code Metric Data, which relates to the performance of specific methods or segments of code within the application. This allows for targeted monitoring and analysis of areas significant to the business's

objectives and technical performance.

Correct Answer: C

To view all captured endpoints by service using the REST interface in AppDynamics, a Performance Analyst would navigate to the Metric Browser and proceed to the "Consumed Endpoints" section. From there, drilling down on specific

endpoints within the Metric Browser allows the analyst to explore the services associated with each endpoint. This method enables detailed analysis of endpoint metrics, facilitating the monitoring and optimization of service performance.

Correct Answer: A

A transaction snapshot in AppDynamics is a detailed report of a single execution of a business transaction. Its primary purpose is to analyze issues with a specific business transaction by providing a comprehensive view of the transaction's

execution path, including timing, call graphs, and database queries. This allows performance analystsand developers to drill down into individual transactions to diagnose performance bottlenecks, errors, or anomalies.

Correct Answer: C

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.
