NEW QUESTION # 13
What are two differences between creating a Transaction Group using the 'Create Group' action and defining a Transaction Detection rule? (Choose two.)
Answer: A,D
NEW QUESTION # 14
A Performance Analyst has noticed a significant decrease in an application's workload (calls/min) and is trying to identify the root cause. Which option will give the Performance Analyst insight into the behavior of the affected Business Transactions?
Answer: A
Explanation:
When a Performance Analyst observes a significant decrease in an application's workload (calls/min), reviewing the "Top Business Transactions by Load" in the Application Dashboard can provide valuable insights. This feature allows the analyst to quickly identify which business transactions have experienced the most significant changes in load, potentially pinpointing the root cause of the overall workload decrease. It offers a focused view of the application's performance, highlighting areas that may require further investigation or immediate action.
References:
AppDynamics documentation on Application Dashboard: Describes the features and capabilities of the Application Dashboard, including how to view and analyze the top business transactions by load.
AppDynamics documentation on Business Transactions: Details the importance of monitoring business transactions and how they can be used to understand application performance trends.
NEW QUESTION # 15
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?
Answer: C
Explanation:
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.
NEW QUESTION # 16
Which option should a Performance Analyst use in an environment where virtual machines are routinely created and destroyed?
Answer: A
Explanation:
In an elastic environment where virtual machines are frequently provisioned and terminated, the Performance Analyst should enable node-name reuse by using -Dappdynamics.agent.reuse.nodeName together with - Dappdynamics.agent.reuse.nodeName.prefix.
The reuse setting allows an Application Agent to register against an available historical node identity rather than continually creating a new node record each time a replacement virtual machine starts. The prefix groups reusable node names for a particular tier, service, or deployment pool, ensuring that agents select node identities from the correct logical set. This prevents excessive node proliferation in the Controller and preserves cleaner historical monitoring for short-lived infrastructure.
A typical configuration enables reuse and supplies a stable prefix, for example:
-Dappdynamics.agent.reuse.nodeName=true
-Dappdynamics.agent.reuse.nodeName.prefix=checkout-node
Proxy properties only control Controller connectivity through an HTTP proxy. Node metadata and a fixed node name do not provide controlled reuse across an automatically scaling pool.
Relevant CAAPA Study Guide topics include Dynamic and Elastic Environments, Node Name Reuse, Application Agent Registration, Tier and Node Configuration, and Controller Node Management.
NEW QUESTION # 17
Periodic Snapshot thresholds can be configured at which two levels? (Choose two.)
Answer: C,D
Explanation:
Periodic Transaction Snapshot thresholds can be configured at the Application level and overridden for an individual Business Transaction.
The application-level configuration establishes the default periodic snapshot behavior for all Business Transactions within the monitored application. This provides a consistent collection policy, including how frequently normal transaction snapshots are captured for ongoing diagnostic visibility.
For a particularly important or high-risk Business Transaction, the Performance Analyst can define transaction-specific settings. The individual-transaction configuration overrides the application default, allowing more frequent or specialized snapshot collection for critical operations such as checkout, payment authorization, login, or order submission.
Periodic snapshot thresholds are not configured directly at the node or tier level. Nodes inherit the transaction- monitoring configuration associated with their application and Business Transactions. Service Endpoints generate their own performance metrics, but they do not use the Business Transaction periodic snapshot threshold model independently.
This hierarchy enables broad application-wide governance while still allowing targeted diagnostic depth for selected transactions. Relevant CAAPA Study Guide topics include Transaction Snapshot Collection, Periodic Snapshots, Application-Level Snapshot Configuration, Business Transaction Overrides, Diagnostic Sessions, and Snapshot Collection Thresholds.
