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. References:

To find the information that shows the current application, tier, and node that the agent currently reports to, you can go to View my settings > AppDynamics Agents section in the Controller UI. This section shows you the list of agents that are connected to the Controller, along with their status, version, application, tier, and node names. You can also filter the list by agent type, status, or application1 References: 1: AppDynamics Agents

Before creating a new database collector, you need to perform the following actions:

• Verify the database connection details. You need to provide the host, port, database name, and credentials for the database that you want to monitor. You also need to select the database type and the collector type1
• Create a database user and set user permissions. You need to create a database user with the minimum required permissions to access the database and run the queries that the Database Agent needs. You can use the scripts provided by AppDynamics to create the user and grant the permissions2

A data collector is used to capture application data in a single business transaction. A data collector is a configuration that specifies what data to capture from a business transaction and how to store it in the AppDynamics Controller or the analytics platform. You can capture data from HTTP requests, method invocations, custom fields, or information points. You can also apply filters and transformations to the captured data. The captured data can be used for various purposes, such as adding context to business transactions, creating custom metrics, triggering health rules, enriching transaction analytics, or creating business journeys.https://university.appdynamics.com/certifications/associate-administrator

According to the Widgets document1, there are various types of widgets that can be used to create visual representations of data in custom dashboards and war rooms. Some of the widget types are:

• Flow Map: A flow map widget displays the flow of traffic between different entities, such as applications, tiers, nodes, backends, and so on. You can customize the flow map to show different metrics, filters, and drill-down options.
• iFrame: An iFrame widget allows you to embed an external web page or another dashboard within a custom dashboard. You can specify the URL, height, and width of the iFrame widget.
• Health List: A health list widget displays the health status of different entities, such as applications, tiers, nodes, business transactions, and so on. You can customize the health list to show different metrics, filters, and drill-down options.

Therefore, the correct answer is A, B, and C. Snapshot and Funnel Analysts are not widget types, but features or tools that can be accessed from other widgets or dashboards. 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.https://docs.appdynamics.com/appd/23.x/latest/en/appdynamics-essentials/dashboards-and-reports/custom-dashboards/create-and-manage-custom-dashboards-and-templates

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>, , and 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 names: 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.

The default length of time events can be viewed with full detail before being purged is 7 days, unless archived. Events are records of significant occurrences in the monitored environment, such as errors, exceptions, policy violations, health rule violations, and more. You can view the events in the Controller UI under Events > All Events. You can also archive the events to retain them for longer periods or export them to external systems1 References: 1: Events
