500-425 Exam Dumps : Cisco AppDynamics Associate Administrator (CAAA)

According to the Diagnostic Sessions document1, a diagnostic session is a timed session in which AppDynamics captures transaction snapshots for a business transaction at a more frequent interval that you set. In the session, AppDynamics captures full call graphs for the transactions. A diagnostic session can be triggered manually or automatically based on a health rule violation or a threshold of slow or error transactions. A diagnostic session is always associated with a specific business transaction, not all business transactions configured. Therefore, the correct answer is B. References:

 The default auto-refresh interval for custom dashboards is 120 seconds. This means that the data displayed on the dashboard will be updated every two minutes. The auto-refresh interval can be configured by the dashboard owner or administrator from the dashboard settings. The auto-refresh interval can be set to any value between 15 and 300 seconds, or disabled altogether. The auto-refresh interval applies to all the widgets on the dashboard, unless a widget has its own refresh interval specified.

According to the Data Collectors document1, a data collector is a configuration that captures application data from a method invocation or an HTTP request. A data collector is associated with a specific method signature or an HTTP parameter name. Therefore, if a new class and method have been deployed to the application, or a new method parameter has been added to an instrumented class, the existing data collector may not match the new code and may need to be updated. However, if the business transaction has been deprecated, or a new HTTP parameter has been added to an existing business transaction, the existing data collector may still work as expected, unless the data collector is specifically configured to filter by the business transaction name or the HTTP parameter value. References:
