Explanation
According to the Actions document1, there are four types of standard controller actions that are available to be created: Notification, Diagnostic, Remediation, and JIRA. Each type of action has different subtypes that perform specific tasks. For example, the Notification type includes Email, SMS, and HTTP Request subtypes, while the Diagnostic type includes Thread Dump, Heap Dump, and Diagnostic Session subtypes. Therefore, the correct answer is D and E, as Email and Thread Dump are subtypes of standard controller actions. Resolve, Close Incident, and Undeploy are not standard controller actions, but they may be custom actions that are created by the user or the administrator. References:

Explanation
According to the Tiers and Nodes document1, establishing standards for naming applications, tiers, and nodes can help you identify and organize the components of your monitored environment, as well as troubleshoot performance issues and health rule violations. Some of the statements about establishing naming conventions are true:
Application Tier and Node values can be configured in the application agent startup script: This is true for Java agents, as you can pass values to the agent that will be used as the application, tier, and node name for the system. For example, you can use the -Dappdynamics.agent.applicationName,
-Dappdynamics.agent.tierName, and -Dappdynamics.agent.nodeName properties to specify the names in the JVM startup script2.
Node names must be unique across the entire business application: This is true, as node names are used to identify the individual instances of the application components that are monitored by AppDynamics. Having duplicate node names can cause confusion and errors in the data collection and reporting. Therefore, you should use a naming convention that ensures uniqueness and clarity for each node1.
Application Tier and Node values can be configured in the controller-info.xml file: This is true for Java agents, as you can also configure the names in the controller-info.xml file, which is located in the
<agent_home>/conf directory. The controller-info.xml file contains the properties that define the agent identity and connection to the Controller. You can use the <application-name>, <tier-name>, and
<node-name> elements to specify the names in the file2.
Some of the statements about establishing naming conventions are false:
Nodes that reside on different Tiers and different machines (hosts) can have duplicate Node name:
This is false, as node names must be unique across the entire business application, regardless of the tier or the host they belong to. Having duplicate node names can cause confusion and errors in the data collection and reporting. Therefore, you should use a naming convention that ensures uniqueness and clarity for each node1.
Nodes that reside on the same Tier but on different machines (hosts) can have duplicate Node names: This is also false, as node names must be unique across the entire business application, regardless of the tier or the host they belong to. Having duplicate node names can cause confusion and errors in the data collection and reporting. Therefore, you should use a naming convention that ensures uniqueness and clarity for each node1.

Explanation
According to the Cisco AppDynamics Associate Administrator Certification document1, one of the topics covered in the exam is "Monitor agent performance and connectivity". To do this, you need to ensure that the application agent can communicate with the controller, which may require SSL configuration if the controller is using SSL2. You also need to check that there are enough licenses available on the controller for the application agent to register and report data3. If the agent is using the wrong application name or does not have enough memory, it may not start at all or may crash, which are different problems from not being able to connect to the controller.

Explanation
Error configuration is a feature in AppDynamics that allows you to exclude certain types of errors and exceptions from being reported on the dashboard. You can use error configuration to filter out noise and focus on the most relevant and actionable issues.
According to the Error Configuration - AppDynamics, the following types of errors and exceptions can be excluded using error configuration:
Database error return codes: These are codes that indicate a problem with the database server, such as
0x80004005 (access denied) or 0x8000005E (access violation). You can exclude these errors from being reported on the dashboard by adding them to the error configuration list.
JavaScript errors: These are errors that occur in the browser due to invalid or malformed JavaScript code, such as syntax errors or reference errors. You can exclude these errors from being reported on the dashboard by adding them to the error configuration list.
Therefore, A (Database error return codes) and C (JavaScript errors) are two options that can be excluded using error configuration. References:

Explanation
An HTTP Data Collector is a type of data collector that captures data from HTTP requests and responses. It can capture three kinds of data: parameter values, headers, and cookies. Parameter values are the values of the query string or form parameters in the HTTP request. Headers are the key-value pairs that are sent or received as part of the HTTP request or response. Cookies are the small pieces of data that are stored by the browser and sent to the server with each request. An HTTP Data Collector can be configured to capture any of these data types by specifying the name of the parameter, header, or cookie in the data collector settings. The captured data can be used for various purposes, such as adding context to business transactions, creating custom metrics, or triggering health rules.
