Cisco AppDynamics Associate Performance Analyst Sample Questions (Q21-Q26):

NEW QUESTION # 21
Which option is a prerequisite for installing the AppDynamics Database Agent?

Answer: D

Explanation:
The database host must be reachable from the Database Agent host. The AppDynamics Database Agent normally runs as a standalone process and connects remotely to monitored database instances. Before installation and configuration, the agent host therefore requires network connectivity to each target database over the appropriate database listener port.
This prerequisite includes successful hostname or IP resolution, routing, firewall access, and permission for the agent host to establish a TCP connection to the database service. The Database Agent also requires valid monitoring credentials with the database-specific permissions needed to collect performance statistics, sessions, waits, queries, and other diagnostic data.
Reviewing frequently used primary keys is a database-design activity and is unrelated to agent installation.
Adjusting tcp_max_syn_backlog is an operating-system network-tuning task, not a standard Database Agent prerequisite. Dropping system-table keys would be unnecessary and potentially damaging; AppDynamics monitoring does not require destructive changes to database system objects.
Relevant CAAPA Study Guide topics include Database Visibility Architecture, Database Agent Deployment, Network Connectivity Requirements, Database Collector Configuration, Listener Ports, and Monitoring User Permissions.


NEW QUESTION # 22
What is the Application Agent limit for Service Endpoints with respect to Controller and Agent configurations?

Answer: A

Explanation:
The Application Agent supports a default maximum of 50 Service Endpoints per entry point type. An entry point type represents the technology or execution mechanism through which the monitored request enters the application, such as a servlet, web service, message listener, or asynchronous processing framework.
This limit prevents excessive endpoint registration and metric creation at both the Agent and Controller layers. When Service Endpoint detection rules identify more endpoints than the configured threshold for a particular entry point type, the Agent restricts registration to the permitted maximum. The limit can be governed through the relevant Agent node-property configuration, but the standard tested value is 50.
The asynchronous-worker-thread options are too narrowly scoped and do not describe the general Service Endpoint registration limit. Likewise, 25 endpoints per entry point type is not the standard default Application Agent threshold.
This distinction is important because Service Endpoints generate independent performance metrics while remaining subordinate to the associated Business Transaction. Relevant CAAPA Study Guide topics include Service Endpoint Detection, Agent and Controller Limits, Entry Point Types, Agent Node Properties, Metric Registration, and Business Transaction Visibility.


NEW QUESTION # 23
Which statement is correct regarding controller-level and tier/node-level dashboards?

Answer: C

Explanation:
Controller-level and tier/node-level dashboards in AppDynamics are treated as separate entities. They are scoped differently, with controller-level dashboards providing a global view across the entire AppDynamics domain, and tier/node-level dashboards being specific to particular tiers or nodes within an application.
Performance Analysts do not have the ability to cross-reference directly between these two sets of dashboards within the AppDynamics UI.

NEW QUESTION # 24

Refer to the exhibit. Using this heap utilization graph, which method is used to confirm if a memory leak is occurring during a certain time frame?

Answer: D

Explanation:
To confirm if a memory leak is occurring, one should refer to the Tiers and Nodes section of the AppDynamics Controller UI, navigate to the Memory tab, and observe the Heap Utilization over time in relation to the Heap's Current Usage (MB) versus the Maximum (MB) allocated. Consistent growth in heap utilization or an upward trend that does not decrement even after garbage collection indicates a potential memory leak.References:AppDynamics documentation on Memory Leak Detection and Heap Analysis.


NEW QUESTION # 25
A Performance Analyst has a full set of health rules in place to proactively detect anomalies in an application.
The analyst wants to send these events to an external alerting system. Which two Create Action options allow integration with a third-party alerting system? (Choose two.)

Answer: C,E

Explanation:
HTTP Request and Custom Actions are the two action types designed to integrate AppDynamics policy events with external alerting or event-management platforms.
An HTTP Request action sends an outbound request to a configured third-party endpoint when a policy is triggered. The analyst can specify the URL, HTTP method, authentication, headers, and event payload. This is commonly used with webhook-enabled alerting, incident-management, automation, and collaboration systems.
A Custom Action extends the Controller's standard action framework through a custom action module. It is appropriate when the external platform requires specialized processing, a proprietary protocol, payload transformation, or integration logic that cannot be handled by a standard HTTP request.
Notifications primarily deliver native email or SMS messages. Diagnostics initiate troubleshooting activities such as diagnostic sessions or thread dumps, while Remediation performs corrective operations. Issue Tracking System Integrations are specifically intended for creating or updating work items in supported issue- management platforms rather than providing a general alerting integration mechanism.
Relevant CAAPA topics include Health Rules, Policies, Policy Actions, HTTP Request Actions, Custom Actions, Webhook Integration, and Third-Party Event Management.
