123. Frage 
Refer to the exhibit. The transaction score in the graphic displays an interesting performance pattern outside of business hours on 6/16/18. Which additional performance anomaly should be of most interest to a Performance Analyst?
Antwort: D
Begründung:
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.

124. Frage
When a team of developers refactored their code, resulting in class-name changes, Business iQ users reported that metrics had disappeared. Where should a Performance Analyst look to troubleshoot this problem?
Antwort: D
Begründung:
The Performance Analyst should review Configuration > Instrumentation > Data Collectors. Business iQ commonly depends on transaction data collected from application code, including values obtained through method invocation data collectors. These collectors can be configured against specific class names, method names, method arguments, return values, object properties, or getter chains.
When developers refactor code and rename or relocate classes, an existing data collector may no longer match the instrumented method. As a result, the expected business data is not captured, and the related Business iQ fields, measures, or metrics can disappear from analytics views even though the application continues processing transactions.
The analyst should verify the configured class and method signatures, confirm that the new classes are instrumented, update any affected getter chains, and validate collection through new transaction snapshots or Analytics data.
The Errors page focuses on application exceptions, while Slow Transaction Thresholds controls performance classifications. Database collectors configure Database Visibility connections and are unrelated to application- code refactoring.
Relevant CAAPA Study Guide topics include Business iQ, Analytics Data Collection, Method Invocation Data Collectors, Class and Method Matching, Getter Chains, Instrumentation Configuration, and Transaction Snapshot Validation.
125. Frage
A Performance Analyst notices an increase in Business Transaction error rate that is much higher than normal alerts. The Performance Analyst can see these are related to the Health Rules defined for the Shopping Service that is monitored with AppDynamics Browser RUM. While troubleshooting the Performance Analyst wants details on which Browsers and Devices are affected. Which section of the Browser App Dashboard will provide this detail for a given time period?
Antwort: A
Begründung:
In the Browser Real User Monitoring (RUM) Dashboard, the Usage Stats section provides insights into user demographics, including the types of browsers and devices they are using. This section would help the Performance Analyst understand which browsers and devices are affected during a specific time period when there has been an increase in the Business Transaction error rate.

126. Frage
By default, how often do the violations displayed on the Health Rules Violations page update?
Antwort: B
Begründung:
By default, an active health rule violation displayed on the Health Rules Violations page is updated at 30- minute intervals after the initial violation event is triggered. AppDynamics first evaluates the health-rule condition against the configured critical or warning criteria. When the condition remains true for the configured evaluation and wait period, the Controller opens a health rule violation event.
While that violation remains active, AppDynamics periodically updates its displayed status and associated event information. The default continuation-update interval is 30 minutes. The violation is subsequently closed when the monitored metric no longer satisfies the violation criteria for the required duration.
The wait time after violation determines how long a condition must persist before AppDynamics opens the violation; it does not define the ongoing update frequency. The page is also not limited to updating only when a new violation starts, nor must an existing violation close before updated information can be recorded.
Relevant CAAPA Study Guide topics include Health Rule Evaluation, Warning and Critical Conditions, Wait Time After Violation, Health Rule Violation Events, Violation Lifecycle, and Controller Event Updates.
127. Frage
A Performance Analyst needs to send a summary report of specific events every two hours. Which feature can enable this automated report summary?
Antwort: C
Begründung:
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.
