NEW QUESTION # 47
What is the Node limit of the maximum Service Endpoints per node?
Answer: B
Explanation:
AppDynamics imposes a limit on the number of Service Endpoints that can be registered per node to ensure manageable performance and overhead. The limit per node is set to 100 Service Endpoints, which is a balance between providing detailed monitoring and maintaining application performance.

NEW QUESTION # 48
Which Application Dashboard view categorizes transactions by load, response time, errors, slow transactions, and stalled transactions in a single aggregated value for a specific time range?
Answer: B
Explanation:
The Transaction Score view in the Application Dashboard categorizes transactions by load, response time, errors, slow transactions, and stalled transactions. It provides an aggregated value for a specific time range, giving an at-a-glance indication of the health and performance of business transactions.

NEW QUESTION # 49
In the Create Scheduled Report form, which built-in scheduled report type provides the transaction scorecard?
Answer: A
Explanation:
The built-in Application Health scheduled report provides the Transaction Scorecard. This report is designed to summarize the operational health of a selected application over the configured reporting period and includes Business Transaction performance classifications.
The Transaction Scorecard shows the distribution of transaction executions across categories such as normal, slow, very slow, stalled, and errors. These classifications are derived from the application's configured transaction thresholds and dynamic baselines. The scorecard therefore gives recipients a concise indication of how much application traffic delivered an acceptable user experience and how much experienced degradation or failure.
The All Application Summary report provides a higher-level overview across applications rather than the detailed transaction scorecard for a specific application. The Home Screen option summarizes Controller- level information and is not the report type used for transaction-performance scoring. User Experience:
Browser Apps focuses on Browser Real User Monitoring measurements, including page-load and end-user response metrics, rather than server-side Business Transaction scoring.
Relevant CAAPA Study Guide topics include Scheduled Reports, Application Health Reports, Transaction Score, Business Transaction Performance Classification, Dynamic Baselines, and Email Report Delivery.
NEW QUESTION # 50
Which option is a prerequisite for installing the AppDynamics Database Agent?
Answer: B
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 # 51
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?
Answer: C
Explanation:
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.
