질문 # 105
Which health rule violation event will be triggered when a Performance Analyst modifies an existing health rule that is already in critical violation?
정답：D
설명：
When an existing health rule is modified while it has an active critical violation, AppDynamics generates a Health Rule Violation Canceled - Critical event. Editing the health rule changes the definition under which the current violation was originally evaluated. The Controller therefore cancels the active violation rather than continuing to evaluate it against a configuration that no longer matches its originating criteria.
A Continues - Critical event is generated when the same active violation remains in the critical state during subsequent evaluation and update intervals without a configuration change. A Started - Critical event indicates that a new critical violation has opened. An Ended - Critical event occurs when the monitored condition returns to an acceptable state according to the unchanged health-rule criteria.
After the rule is modified, AppDynamics evaluates the revised conditions as a new monitoring definition. If those revised criteria are subsequently breached, a new violation-start event can be generated.
Relevant CAAPA Study Guide topics include Health Rule Violation Lifecycle, Critical and Warning Events, Rule Modification Behavior, Violation Cancellation, Evaluation Criteria, and Policy Event Triggers.
질문 # 106
An AppDynamics deployment has Business Transaction Lock Down turned on. The company has just added an important service to its application and wants to track this service as a unique Business Transaction. What action is needed to achieve this?
정답：C
설명：
With Business Transaction Lock Down enabled, AppDynamics prevents automatically discovered traffic from registering additional Business Transactions. Newly observed requests that do not match an existing registered transaction are generally aggregated under the tier's All Other Traffic transaction, protecting the Controller from uncontrolled Business Transaction growth.
To monitor the new web service as an explicitly named, unique Business Transaction, the Performance Analyst should create a Custom Transaction Match Rule. The rule can identify the service by its Web Service Name and Operation Name, providing deterministic matching and naming independently of automatic transaction discovery. Custom rules are the appropriate mechanism for intentionally introducing important transactions while maintaining lockdown governance.
Changing the automatic discovery rule does not overcome the purpose of lockdown because new automatically discovered transactions remain restricted. Live Preview assists with validating detection-rule behavior but is not the persistent configuration that defines the transaction. All Other Traffic provides aggregated visibility into unregistered traffic; it does not replace a precise custom detection rule.
Relevant CAAPA Study Guide topics include Business Transaction Lock Down, Custom Match Rules, Web- Service Entry Points, Transaction Naming, Automatic Discovery, and All Other Traffic.
질문 # 107
Which three pieces of information are required when creating a new database collector? (Choose three.)
정답：A,B
설명：
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.
질문 # 108
A team of developers deploys new Java servlet code that should create new business transactions in AppDynamics. After applying load on the new code function, there are no new Business Transactions on the Business Transaction Dashboard. Whichtwo options should the developers check in AppDynamics to make sure the Business Transactions can be discovered?
[Choose two.)
정답：C,D
설명：
When new business transactions are not appearing on the Business Transaction Dashboard after deploying new code, developers should verify that there are no exclusion rules in place on the tier where the new code was deployed. Additionally, it is crucial to ensure that the Auto Discovery feature for servlets is enabled for Java agents, as this allows AppDynamics to automatically detect and name business transactions based on incoming requests to servlets. Both of these checks are necessary to ensure that new business transactions can be discovered and monitored.References:AppDynamics documentation on Business Transaction detection and Java Agent configuration.
질문 # 109
A client needs to reference a metric from different applications on an AppDynamics dashboard. Which of the following is true?
정답：C
설명：
In AppDynamics, metrics from different applications can indeed be cross-referenced on a single dashboard.
This allows for a more holistic view of an organization's application ecosystem, facilitating the comparison and correlation of performance metrics across different applications within the same AppDynamics controller.
References:
AppDynamics documentation on Custom Dashboards: Details how to create custom dashboards that can include metrics from multiple applications, enabling cross-referencing and comprehensive performance monitoring.
