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:

To properly configure a database agent from a zip file, you need to provide the following minimum details:

Controller Host: This is the hostname or IP address of the machine where the Controller is installed.You need to specify this so that the Database Agent can communicate with the Controller and send the collected data1

Controller Port: This is the port number that the Controller listens on for incoming connections. You need to specify this so that the Database Agent can connect to the Controller using the correct protocol.The default ports are 8090 for HTTP and 8181 for HTTPS for on-premise Controllers, and 80 for HTTP and 443 for HTTPS for SaaS Controllers1

Account Access Key: This is the key that authenticates the Database Agent with the Controller. You need to specify this so that the Database Agent can register itself with the Controller and access the license.You can find the account access key in the Controller UI under Settings > License > Account1

Account Name: This is the name of the account that the Database Agent belongs to. You need to specify this so that the Database Agent can associate itself with the correct application and user permissions.You can find the account name in the Controller UI under Settings > License > Account1

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 /conf directory. The controller-info.xml file contains the properties that define the agent identity and connection to the Controller.You can use the , <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 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.

When troubleshooting an application using AppDynamics, the fastest way to narrow down a code problem with a specific business transaction is to follow this order:

Review Application Dashboard: This is the first step to get an overview of the health and performance of your application and its components. You can see the key metrics, such as response time, throughput, error rate, and load, for each tier, node, and business transaction. You can also see the health rule violations, events, and alerts that indicate any issues or anomalies in your application.

Check transaction scorecard: This is the second step to drill down to the details of a specific business transaction that you want to troubleshoot. You can see the transaction scorecard by clicking on the business transaction name on the application dashboard. The transaction scorecard shows the metrics, such as average response time, calls per minute, errors per minute, and slow calls, for the selected business transaction. You can also see the breakdown of the response time by tier, node, and remote service, and the distribution of the response time by percentile.

Check transaction snapshots for problems: This is the third step to identify the root cause of the code problem for the selected business transaction. You can see the transaction snapshots by clicking on the View Snapshots button on the transaction scorecard. Transaction snapshots are the detailed records of the execution of a business transaction, including the call graph, the exit calls, the errors, the exceptions, the logs, the HTTP parameters, the cookies, the session attributes, and the custom data. You can use the transaction snapshots to analyze the code execution, the database queries, the web service calls, the message queues, the errors, and the exceptions that affect the performance of the business transaction.

Therefore,A(Review Application Dashboard > Check transaction scorecard > Check Transactions snapshots for problems) is the correct answer.Reference:

To alert the operations team that a cloud-based application has provisioned a new instance of a JVM, an administrator should create a policy trigger for Discovery > New Node Discovered. This policy trigger will fire an event when a new node is discovered by the AppDynamics Controller, either by auto-discovery or manual registration. The event will contain information such as the node name, tier name, application name, and agent type. The administrator can then configure an action to send an email, SMS, or custom notification to the operations team with the event details. Alternatively, the administrator can also use the built-in alerting feature of the cloud provider to notify the operations team of the new instance creation.
