AWS Certified SysOps Administrator – Associate (legacy) — Question 574

Can a user depict CloudWatch metrics such as CPU utilization in % and Network I/O in bytes on a single graph?

Answer options

• A. No, a user cannot graph two separate metrics on the same graph.
• B. Yes, a user can graph several metrics over time on a single graph.
• C. No, a user cannot plot several metrics on a single graph since the units are different.
• D. Yes, a user can graph multiple metrics on the same graph provided they are of the same instance in the same AZ.

Correct answer: B

Explanation

Amazon CloudWatch allows you to graph multiple metrics on a single chart, even if they use different units, by leveraging a secondary Y-axis. This enables easy correlation of diverse performance indicators, such as CPU utilization and Network I/O, over the same time frame. There are no restrictions requiring the metrics to share the same units or originate from the exact same instance and Availability Zone.
