Which AWS service or tool will monitor AWS resources and applications in real time?

Answer options

Correct answer: B

Explanation

Amazon CloudWatch is designed to monitor AWS resources and applications in real time by collecting metrics, logs, and events.

AWS Cost Explorer is focused strictly on analyzing and visualizing your AWS spending over time.
