問題 #64
How can a Business Transaction be permanently deleted?

A. Use Business Transaction Automatic Cleanup
B. Modify the detection rule and delete the Business Transaction
C. Delete the transaction from the Business Transaction list
D. Exclude the transaction from the Business Transaction list and delete the Business Transaction

答案：D

解題說明：
To permanently remove a Business Transaction, the analyst must first exclude it from transaction detection and then delete it from the Business Transaction list. Deleting the transaction alone removes its current registration and associated visibility from the Controller, but the Application Agent can rediscover and register it again when matching traffic is observed.
An exclusion rule prevents future requests matching the specified entry point or transaction criteria from being detected as that Business Transaction. After the exclusion is configured and applied, the existing Business Transaction can be deleted safely without being recreated by automatic discovery.
Business Transaction Automatic Cleanup removes stale or inactive transactions according to retention and cleanup criteria; it does not prevent an active transaction from being rediscovered. Merely deleting the transaction from the list is therefore temporary when matching requests continue. Modifying a detection rule may alter transaction classification, but the explicit and reliable method for permanent removal is to exclude the transaction before deleting its existing registration.
Relevant CAAPA Study Guide topics include Business Transaction Detection, Exclude Rules, Automatic Discovery, Business Transaction Registration, Transaction Cleanup, and Business Transaction Management.

問題 #65
When using the REST interface, where would a Performance Analyst go to see all captured endpoints by service?

A. Navigate to the Applications browser, drill down to the requested endpoint, select the available dashboard and metric indicators, and then select the desired metric.
B. Navigate to the Metric Browser, open the Consumed Endpoints location, and drill down into a specific endpoint to identify its services.
C. Access the MySQL database, locate all endpoints in an application, drill down to the tiers and transactions, and select the REST feature enabled by the Service Endpoint.
D. Navigate to the Metric Browser, locate a specific metric, copy its REST URL, and use a wildcard query to retrieve metrics for the other Service Endpoints.

答案：D

解題說明：
The Metric Browser provides the authoritative metric hierarchy and can generate the REST URL corresponding to a selected Service Endpoint metric. A Performance Analyst first navigates to a representative Service Endpoint and metric, then copies the generated REST URL. The metric path in that URL can be modified with supported wildcard expressions to return matching metrics for all captured Service Endpoints or services within the application.
This method avoids manually constructing an unfamiliar metric path and ensures that the application identifier, metric hierarchy, time-range parameters, and REST endpoint syntax are correct. Wildcards allow the analyst to query multiple Service Endpoint names, tiers, or metric branches in one request.
Direct access to the Controller's underlying database is unsupported and bypasses the Controller API model.
The Applications browser is useful for interactive analysis but does not itself provide the most direct REST- query construction workflow. "Consumed Endpoints" is not the required location for enumerating all Service Endpoint metrics through the REST interface.
Relevant CAAPA Study Guide topics include Metric Browser, Service Endpoint Metrics, Metric Data REST API, Metric Paths, Wildcard Queries, and REST URL Generation.

問題 #66
What are three effects of Development Level Monitoring? (Choose three.)

A. The agent captures a combination of full and partial call graphs in development mode.
B. The agent attempts to take a snapshot for every transaction.
C. The agent guarantees a snapshot for every transaction.
D. The agent captures full call graphs in development mode.
E. The agent ignores the "dev-mode-suspend-cpm" property.
F. AppDynamics increases information collected for exit calls to backend systems.

答案：B,D,F

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 #67
Where would a Performance Analyst view detailed trend graphs representing application performance from the viewpoint of the end user in AppDynamics?

A. Applications
B. Browser Apps
C. Transaction Analytics
D. Remote Services

答案：B

解題說明：
The Performance Analyst should use Browser Apps. This area contains Browser Real User Monitoring data and presents application performance from the actual end user's perspective. It provides detailed trend graphs for browser pages and AJAX requests, including metrics such as end-user response time, page load time, network time, server time, DOM processing time, resource-loading time, request volume, errors, and geographic or browser-related performance variations.
These measurements enable the analyst to determine whether a performance problem originates in the browser, network, content-delivery path, application server, or a downstream dependency. The graphs can also be filtered by time range, page, browser type, device, operating system, location, and other user-session dimensions.
Transaction Analytics is used for querying and analyzing transaction and business-event data. Remote Services focuses on backend dependencies and external service calls. Applications primarily provides server- side APM visibility into Business Transactions, tiers, nodes, and application flow.
Relevant CAAPA Study Guide topics include Browser Real User Monitoring, Browser Applications, End- User Response Time, Page and AJAX Performance, User Experience Analysis, and Client-Side Performance Trends.

問題 #68
Which type of Data Collector will capture code data such as method arguments, variables, and return values?

A. Transaction Data Collector
B. Servlet Container Collector
C. URI Data Collector
D. Method Invocation Data Collector

答案：D

解題說明：
The "Method Invocation Data Collector" is specifically designed to capture code-level data such as method arguments, variables, and return values. This type of data collector enables deep visibility into the execution of methods within transactions, providing valuable insights into the application's behavior and performance. This detailed level of monitoring is essential for diagnosing complex issues and understanding the inner workings of business transactions.
