問題 #91
What are three effects of Development Level Monitoring? (Choose three.)

答案:A,C,E

解題說明:
Development Level Monitoring is intended for controlled development or diagnostic environments where maximum transaction visibility is more important than minimizing agent overhead. In this mode, the agent captures full call graphs, providing method-level execution detail rather than the reduced or partial call-graph collection associated with normal production monitoring.
The agent also attempts to collect a transaction snapshot for every transaction. "Attempts" is the critical distinction: snapshot creation remains subject to agent safeguards, resource constraints, transaction behavior, and collection limits. Therefore, Development Level Monitoring does not provide an absolute guarantee that every transaction will produce a retained snapshot, making option F incorrect.
Development mode additionally collects more detailed exit-call information for calls to backend systems, improving analysis of downstream databases, services, and other remote dependencies.
The agent does not ignore dev-mode-suspend-cpm. This property is a protective calls-per-minute threshold that can suspend development-mode collection when transaction volume becomes excessive. Relevant CAAPA Study Guide topics include Agent Configuration, Monitoring Levels, Transaction Snapshots, Call Graph Collection, Exit Calls, and Development-Mode Performance Safeguards.


問題 #92
Using the Business Transaction Discovery Sessions tools, which two items can a Performance Analyst browse? (Choose two.)

答案:B,D

解題說明:
Business Transaction Discovery Sessions allow a Performance Analyst to browse the application's classes and methods while identifying suitable entry points for custom Business Transaction detection. The discovery process observes application execution and exposes loaded or invoked code structures, enabling the analyst to locate the class and method that represent the beginning of a meaningful transaction.
Browsing classes helps narrow the search to the relevant package or application component. After selecting a class, the analyst can inspect its methods and choose the appropriate method as the transaction entry point.
This is particularly useful when automatic discovery does not recognize a proprietary framework, background process, scheduled task, or other nonstandard execution path.
Database Calls are analyzed as exit calls or backend activity rather than browsed as transaction entry-point code. JMX MBeans are accessed through JMX monitoring and metric configuration tools. Memory Objects are examined through memory diagnostics, object instance tracking, or leak-detection functions, not Business Transaction Discovery Sessions.
Relevant CAAPA Study Guide topics include Business Transaction Discovery Sessions, Class and Method Browsing, Custom Match Rules, Entry-Point Configuration, Automatic Discovery, and Application Agent Instrumentation.


問題 #93
Which Application Dashboard view categorizes transactions by load, response time, errors, slow transactions, and stalled transactions in a single aggregated value for a specific time range?

答案:B

解題說明:
The Transaction Score view in the Application Dashboard categorizes transactions by load, response time, errors, slow transactions, and stalled transactions. It provides an aggregated value for a specific time range, giving an at-a-glance indication of the health and performance of business transactions.

問題 #94
A Performance Analyst received an alert that the Average Response Time is increasing after a new marketing offer was released. Which metric would quickly help the Performance Analyst determine that users may not be critically impacted?

答案:C

解題說明:
If the Average Response Time is increasing after the release of a new marketing offer, seeing an increase in Calls per Minute could quickly help the Performance Analyst determine that users may not be critically impacted. This increase may indicate that despite the higher average response time, more users are engaging with the application, possibly due to interest generated by the marketing offer. It suggests that the system is handling more load, which could be a factor in the increased response time.
References:
AppDynamics documentation on Performance Metrics: Discusses the implications of various key performance indicators, including how an increase in Calls per Minute can be interpreted in the context of application performance.


問題 #95
In the Create Scheduled Report form, which built-in scheduled report type provides the transaction scorecard?

答案:A

解題說明:
The built-in Application Health scheduled report provides the Transaction Scorecard. This report is designed to summarize the operational health of a selected application over the configured reporting period and includes Business Transaction performance classifications.
The Transaction Scorecard shows the distribution of transaction executions across categories such as normal, slow, very slow, stalled, and errors. These classifications are derived from the application's configured transaction thresholds and dynamic baselines. The scorecard therefore gives recipients a concise indication of how much application traffic delivered an acceptable user experience and how much experienced degradation or failure.
The All Application Summary report provides a higher-level overview across applications rather than the detailed transaction scorecard for a specific application. The Home Screen option summarizes Controller- level information and is not the report type used for transaction-performance scoring. User Experience:
Browser Apps focuses on Browser Real User Monitoring measurements, including page-load and end-user response metrics, rather than server-side Business Transaction scoring.
Relevant CAAPA Study Guide topics include Scheduled Reports, Application Health Reports, Transaction Score, Business Transaction Performance Classification, Dynamic Baselines, and Email Report Delivery.
