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.Reference:

Correct : B

When you have a custom dashboard that has only one widget, you can delete that widget by clicking the Delete Widget button on the widget properties panel. This will remove the widget from the dashboard, but it will not delete the dashboard itself. You can still view and edit the dashboard from the Controller UI or the Events Service.

According to theCreate and Manage Custom Dashboards and Templates - AppDynamics, when you delete a widget from a custom dashboard, AppDynamics does not create a blank widget because empty dashboards are not allowed. Instead, it preserves the existing widgets on the dashboard and displays them in a single row.

Therefore,B(The widget is deleted, but an empty custom dashboard is maintained) is true.Reference:

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. https://docs.appdynamics.com/appd/23.x/latest/en/appdynamics-essentials/dashboards-and-reports/custom-dashboards/create-and-manage-custom-dashboards-and-templates

Correct : C, D

The App Server agent configuration GUI allows you to set the configuration for the following agent properties:

Node-name: This property defines the name of the node that appears in the Controller UI.You can use the GUI to change the node name or use auto-naming rules based on environment variables or system properties1

Max-business-transactions per node: This property sets the maximum number of business transactions that can be registered on a node. If the number of business transactions exceeds this limit, the agent stops registering new business transactions and reports them as ''All Other Traffic''.You can use the GUI to increase or decrease this limit2

Correct : B, C

An exception in AppDynamics is a code-level event that indicates a problem or abnormality in the execution of a business transaction. AppDynamics captures and presents information on exceptions in the monitored environment, and allows you to configure the rules and criteria for detecting and reporting exceptions.

According to theErrors and Exceptions - AppDynamics, the following two types of events would be marked as an exception in AppDynamics:

A custom-configured error method and error message: This is a type of event that you can define as an exception based on a specific method and message that indicate an error condition in your application code. You can configure the error detection rules to mark a business transaction as an error and capture the exception information when such a method and message are encountered. For example, you can configure a rule to mark a business transaction as an error and capture the exception when the methodcom.example.MyClass.myMethodreturns the messageInvalid input.

Any message that is logged with a severity of Error or Fatal: This is a type of event that AppDynamics automatically detects as an exception based on the log messages that are generated by your application code. AppDynamics scans the log messages for the keywordsErrororFatal, and marks the business transaction as an error and captures the exception information when such a message is found. For example, AppDynamics will mark a business transaction as an error and capture the exception when the log message containsError: Null pointer exception.

Therefore,B(a custom-configured error method and error message) andC(any message that is logged with a severity of Error or Fatal) are two types of events that would be marked as an exception in AppDynamics.Reference:
