質問 # 41 
Refer to the exhibit. On which tab will the configured transaction threshold be found?
正解：A
解説：
In Cisco AppDynamics, the transaction threshold configurations are typically found under the "Overview" tab.
This is where you can view the health rule violations and performance baselines that are associated with transaction snapshots, which can include the configured transaction thresholds. These thresholds set the acceptable performance limits for transactions, and when these limits are exceeded, it may trigger health rule violations that are visible on the Overview tab.

質問 # 42
Developers and operations personnel complain that the Controller tracks many irrelevant Java classes and methods. How does a Performance Analyst exclude this unhelpful information?
正解：D
解説：
The Performance Analyst should navigate to Configuration > Instrumentation > Call Graph Settings and configure package exclusions. Call Graph Settings control which Java packages, classes, and methods the Application Agent includes when constructing call graphs for transaction snapshots.
Excluding irrelevant package prefixes removes low-value framework, utility, generated-code, or third-party method detail from captured call graphs. This reduces diagnostic noise, makes transaction snapshots easier for developers to interpret, and can lower instrumentation and data-collection overhead. Exclusions should be applied carefully so that application-owned packages and methods required for root-cause analysis remain visible.
The controller-info.xml file contains Java Agent registration and Controller connectivity settings, such as the Controller address, account information, application, tier, and node identity. It is not the appropriate location for call-graph package exclusions. Baselines evaluate normal metric behavior and have no effect on instrumented classes or methods. The mbeans-server.xml file concerns JMX or MBean-related monitoring rather than Java call-graph filtering.
Relevant CAAPA Study Guide topics include Instrumentation Configuration, Call Graph Settings, Package Exclusions, Java Agent Overhead Management, Transaction Snapshots, and Code-Level Visibility.
質問 # 43
How can a Business Transaction be permanently deleted?
正解：C
解説：
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.
質問 # 44
Which option should a Performance Analyst use in an environment where virtual machines are routinely created and destroyed?
正解：D
解説：
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.
質問 # 45
After reviewing a problem that caused an outage, a Performance Analyst wants to create a single health rule that evaluates multiple conditions. Which two options are valid condition-matching values? (Choose two.)
正解：B、C
解説：
AppDynamics health-rule criteria provide two supported methods for evaluating multiple conditions: All of the following conditions are met and Any of the following conditions are met.
Selecting All applies logical AND behavior. Every configured condition must evaluate as true during the health rule's evaluation period before AppDynamics generates the warning or critical violation. For the outage scenario, this is the appropriate selection when the alert must occur only when several symptoms- such as elevated response time, increased errors, and high CPU utilization-happen together.
Selecting Any applies logical OR behavior. AppDynamics creates the violation when at least one configured condition becomes true. This is useful when several independent symptoms can indicate the same operational problem.
Although "And" and "Or" describe the underlying logical concepts, they are not the named values presented for multi-condition health-rule evaluation in this context. The interface uses All and Any.
Relevant CAAPA Study Guide topics include Health Rule Conditions, Warning and Critical Criteria, Condition Evaluation Logic, Evaluation Time, Violation Wait Time, and Policy Triggering.
