NEW QUESTION # 88
If a user request results in the discovery of an entry point, what is the one key item that must be defined as one or more asynchronous activities are spawned?
Answer: D
Explanation:
A Business Transaction must be defined when a discovered entry point initiates one or more asynchronous activities. The Business Transaction establishes the logical monitoring context for the original user request and enables AppDynamics to associate subsequently spawned asynchronous work with that request.
When asynchronous processing occurs, execution may continue on different threads, task executors, queues, or callback mechanisms after the initiating thread has completed or moved on. AppDynamics propagates the Business Transaction correlation context across these asynchronous boundaries so the resulting activity can be represented as part of the same end-to-end transaction. This allows the analyst to evaluate total response time, asynchronous segments, downstream calls, errors, and call-graph execution in the proper transaction context.
A Custom Endpoint is not required merely because asynchronous work is spawned. Asynchronous metrics and endpoint metrics are measurements generated from monitoring; they do not establish the identity or correlation boundary of the request.
Relevant CAAPA Study Guide topics include Business Transaction Discovery, Entry Points, Asynchronous Transaction Tracking, Thread Handoffs, Transaction Correlation, Call Graphs, and End-to-End Transaction Visibility.
NEW QUESTION # 89
Which three programming languages are supported by the AppDynamics Application Performance Monitoring solution? (Choose three.)
Answer: B,C,E
Explanation:
The supported programming-language options are Go, C/C++, and C#. AppDynamics provides monitoring capabilities for applications built with these languages through language-specific agents, supported runtime instrumentation, or application-monitoring SDKs.
C# is monitored through the AppDynamics .NET Agent, which instruments supported .NET and .NET Framework applications to discover Business Transactions, collect call graphs, monitor exceptions, and correlate downstream service calls. C/C++ applications can be monitored using the AppDynamics C/C++ SDK and associated application instrumentation capabilities, enabling custom Business Transaction definition, exit-call tracking, and distributed transaction correlation. Go applications are supported through AppDynamics monitoring components designed for Go-based services, allowing transaction visibility and correlation within distributed application environments.
Perl is not listed as a standard AppDynamics APM language-agent platform. React is a JavaScript user- interface library rather than a programming language; browser-side React applications are typically observed through Browser Real User Monitoring. iOS Family describes a mobile platform, not a programming language, and is addressed through Mobile Real User Monitoring.
Relevant CAAPA topics include Application Agent Platforms, .NET Agent, C/C++ SDK, Go Application Monitoring, Business Transaction Instrumentation, and Real User Monitoring.
NEW QUESTION # 90
How does a Performance Analyst identify if automatic remediation has been taken for a health rule violation?
Answer: C
Explanation:
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.
NEW QUESTION # 91
In which two cases does AppDynamics start transaction snapshots? (Choose two.)
Answer: B,C
Explanation:
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.
NEW QUESTION # 92
What are two examples of backend calls? (Choose two.)
Answer: B,C
Explanation:
A remote services call and a tier-to-tier request are examples of outbound backend or dependency calls made while processing a Business Transaction.
A remote services call occurs when application code invokes an external HTTP service, web service, messaging destination, or another remote system. AppDynamics detects the associated exit point and reports metrics such as call count, response time, and errors. When the remote destination is not instrumented, it is typically represented as a backend or remote service on the application flow map.
A tier-to-tier request occurs when one monitored application tier calls another instrumented tier.
AppDynamics correlates the outbound exit call with the downstream entry point, producing cross-tier transaction visibility and showing how much downstream processing contributes to total response time.
An asynchronous request represents an execution or thread-handoff pattern and does not inherently constitute a backend call; it may execute entirely within the same tier. A browser request is an inbound entry-point request from an end user, not an outbound dependency invocation.
Relevant CAAPA Study Guide topics include Backend Detection, Exit Calls, Remote Services, Cross-Tier Correlation, Tier-to-Tier Calls, Business Transaction Flow Maps, and Asynchronous Transaction Tracking.
