A Company Has a Web Application That Is Experiencing Performance

Multiple Choice

A company has a web application that is experiencing performance problems many times each night. A root cause analysis reveals spikes in CPU utilization that last 5 minutes on an Amazon EC2 Linux instance. A SysOps administrator is tasked with finding the process ID (PID) of the service or process that is consuming more CPU. How can the administrator accomplish this with the LEAST amount of effort?

A) Configure an AWS Lambda function in Python 3.7 to run every minute to capture the PID and send a notification.
B) Configure the procstat plugin to collect and send CPU metrics for the running processes.
C) Log in to the EC2 Linux instance using a .pem key each night and then run the top command.
D) Use the default Amazon CloudWatch CPU utilization metric to capture the PID in the CloudWatch dashboard.
