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:
