91. Frage
Which two match conditions can be added when you configure an Information Point? (Choose two.)
Antwort: C,D
Begründung:
When configuring an Information Point in AppDynamics, you can add match conditions to refine what gets measured. Match conditions based on a regex applied to the method allow you to specify which methods to include based on a regular expression pattern. Matching based on the invoked object allows you to specify which objects' methods are included, filtering the data according to the object type or instance. These conditions help in pinpointing specific methods or objects for which you want to collect runtime information.References:AppDynamics documentation on Information Points and Match Conditions.
92. Frage
Which three pieces of information are required when creating a new database collector? (Choose three.)
Antwort: A,B
Begründung:
When creating a new database collector in AppDynamics, the essential pieces of information required include the "Database hostname/IP address," "Database Type," and "Port number." These details are crucial for establishing a connection to the database and ensuring accurate monitoring. The hostname/IP address identifies the server where the database is hosted, the Database Type specifies the database management system (e.g., MySQL, Oracle), and the Port number is necessary for network communication with the database server.
References:
AppDynamics documentation on Database Visibility: This section explains how to set up database collectors, including the required information for successful configuration.
93. Frage
In which two cases does AppDynamics start transaction snapshots? (Choose two.)
Antwort: A,D
Begründung:
AppDynamics initiates transaction snapshot collection when a Business Transaction is classified as slow, very slow, stalled, or erroneous, subject to the configured snapshot thresholds and agent collection limits. These snapshots preserve detailed diagnostic context, including call graphs, exit calls, errors, and participating tiers, allowing analysts to isolate the code path or downstream dependency responsible for degraded user experience.
AppDynamics also captures snapshots through periodic snapshot collection. Periodic collection samples transactions at configured intervals even when their performance is normal. This provides representative diagnostic evidence and enables comparison between healthy and problematic executions without requiring every transaction to violate a performance threshold.
A sudden increase in Calls per Minute does not, by itself, constitute a standard snapshot trigger. Workload surges may influence application performance, but snapshots begin only when an applicable collection mechanism or diagnostic condition is satisfied. An "asynchronous session" is also not a standard snapshot- start condition; asynchronous processing can be included within a correlated snapshot after collection has already been initiated.
Relevant CAAPA Study Guide topics include Transaction Snapshots, User Experience Classification, Slow and Error Transactions, Periodic Snapshot Collection, Call Graphs, and Snapshot Collection Thresholds.
94. Frage
Business users of an e-commerce site want to see the running aggregate checkout value stored in the Java class Checkout. How would a Performance Analyst capture this data?
Antwort: A
Begründung:
A method invocation data collector is used because the required business value exists inside the Java application's Checkout class rather than in the HTTP request.
The Performance Analyst configures the collector against the appropriate class and method, then identifies the value through a method argument, return value, object field, or getter chain. AppDynamics captures that checkout value when the configured method executes and associates it with the corresponding Business Transaction data. The collected value can subsequently be used for business analysis and aggregation, allowing stakeholders to report total or running checkout value over a selected time period.
A dashboard widget can visualize or aggregate data that AppDynamics already collects, but it cannot independently extract a value from Java code. An HTTP data collector is appropriate only when the required value is contained in request parameters, headers, cookies, session attributes, or other HTTP data. A REST export retrieves existing Controller data and therefore does not solve the initial instrumentation requirement.
Relevant CAAPA Study Guide topics include Method Invocation Data Collectors, Java Class and Method Instrumentation, Getter Chains, Business Data Collection, Transaction Analytics, and Custom Dashboard Visualization.
95. Frage
A Performance Analyst has noticed a significant decrease in an application ' s workload, measured in calls per minute, and is trying to identify the root cause. Which option will give the Performance Analyst insight into the behavior of the affected Business Transactions?
Antwort: C
Begründung:
The Performance Analyst should open the Business Transactions view and enable Show Trends. This presents historical behavior for individual Business Transactions, making it possible to identify which transactions experienced a decline in calls per minute and when the change began. The analyst can compare workload patterns across transactions and correlate the decrease with changes in response time, errors, transaction activity, or application usage.
The Top Business Transactions by Load widget emphasizes the highest-volume transactions for the selected period, but it may not clearly expose transactions whose volume has sharply declined. Plotting application- level Calls/min in the Metric Browser confirms that total workload decreased but does not immediately identify the affected Business Transactions. The Application Flow Map focuses on tier and dependency relationships, while Transaction Score summarizes transaction performance classifications rather than workload trends.
The Show Trends capability is therefore the most direct method for examining historical transaction behavior and isolating the Business Transactions responsible for the workload change.
Relevant CAAPA Study Guide topics include Business Transaction Monitoring, Show Trends, Calls per Minute, Workload Analysis, Historical Comparison, and Application Performance Troubleshooting.
