NEW QUESTION # 87
A Performance Analyst has decided to replace a Servlet Business Transaction with a Service Endpoint. There were no Business Transaction Custom Match Rules, and the analyst created a Business Transaction Custom Exclude Rule matching the transaction URI. The analyst also created a Service Endpoint Custom Match Rule matching the URI. Which statement is true?
Answer: C
Explanation:
The custom exclude rule prevents the servlet request from being registered and monitored as a Business Transaction, while the Service Endpoint custom match rule independently instruments the matching URI as a Service Endpoint. AppDynamics therefore continues to collect Service Endpoint metrics, including average response time, calls per minute, and errors, allowing the analyst to monitor the service's performance without consuming a Business Transaction registration.
The excluded request does not produce normal Business Transaction snapshots, so the analyst cannot rely on snapshot call graphs to inspect the Service Endpoint or its downstream exit calls. Exit-point visibility is normally obtained through Business Transaction snapshots and call graphs.
EUM correlation also depends on the server-side request being represented as a correlated Business Transaction. A standalone Service Endpoint does not replace that Business Transaction correlation path and therefore cannot provide equivalent browser or mobile EUM linkage.
Relevant CAAPA Study Guide topics include Service Endpoint Detection, Custom Service Endpoint Match Rules, Business Transaction Exclude Rules, Service Endpoint Metrics, Transaction Snapshots, Exit Calls, and EUM Correlation.
NEW QUESTION # 88
By default, how often do the violations displayed on the Health Rules Violations page update?
Answer: D
Explanation:
By default, an active health rule violation displayed on the Health Rules Violations page is updated at 30- minute intervals after the initial violation event is triggered. AppDynamics first evaluates the health-rule condition against the configured critical or warning criteria. When the condition remains true for the configured evaluation and wait period, the Controller opens a health rule violation event.
While that violation remains active, AppDynamics periodically updates its displayed status and associated event information. The default continuation-update interval is 30 minutes. The violation is subsequently closed when the monitored metric no longer satisfies the violation criteria for the required duration.
The wait time after violation determines how long a condition must persist before AppDynamics opens the violation; it does not define the ongoing update frequency. The page is also not limited to updating only when a new violation starts, nor must an existing violation close before updated information can be recorded.
Relevant CAAPA Study Guide topics include Health Rule Evaluation, Warning and Critical Conditions, Wait Time After Violation, Health Rule Violation Events, Violation Lifecycle, and Controller Event Updates.
NEW QUESTION # 89
Which option should a Performance Analyst use in an environment where virtual machines are routinely created and destroyed?
Answer: D
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 # 90
What are two differences between creating a Transaction Group using the 'Create Group' action and defining a Transaction Detection rule? (Choose two.)
Answer: C,D
Explanation:
Creating a Transaction Group using the 'Create Group' action in AppDynamics allows for the aggregation of data from multiple transactions under a single group, facilitating a consolidated view of similar transactions.
This differs from defining a Transaction Detection Rule, which typically focuses on identifying and categorizing individual transactions based on specific criteria. Transaction Groups do not change the names of incoming requests nor reduce the number of overall business transactions; instead, they provide a method for organizing and analyzing related transactions collectively, offering a streamlined approach compared to individually configuring Transaction Detection Rules for each transaction.
References:
AppDynamics documentation on Business Transactions: Covers the concept of Transaction Groups and their role in organizing and analyzing transaction data, as well as the process for creating and managing Transaction Detection Rules.
NEW QUESTION # 91
A Business Transaction was registered and displayed on the Business Transaction Dashboard. It has continuous load on it. After an hour, the Business Transaction stopped being displayed in the Business Transaction Dashboard. Which action stopped the display of the Business Transaction?
Answer: A
Explanation:
Excluding the Business Transaction from the Business Transaction Dashboard removes it from the displayed transaction list even while traffic continues to execute. Exclusion is specifically intended to suppress unwanted or low-value transactions from normal Business Transaction visibility and prevent them from consuming monitored transaction capacity.
Deleting the Business Transaction alone would not reliably keep it absent. Because the transaction has continuous load, the Application Agent could rediscover and register it again, causing it to reappear. Enabling Business Transaction Lock Down prevents newly discovered transactions from being registered, but it does not automatically remove Business Transactions that were already registered before lockdown was enabled.
Deleting a Custom Match Rule also does not directly remove the existing registered Business Transaction.
The transaction might remain registered, or automatic transaction discovery could continue detecting the same entry point.
Therefore, the action that directly explains why the continuously active transaction stopped appearing is that it was excluded from the Business Transaction Dashboard.
Relevant CAAPA topics include Business Transaction Exclusion, Transaction Registration, Automatic Rediscovery, Business Transaction Lock Down, Custom Match Rules, and Dashboard Visibility.
