You need a CloudWatch dashboard to display CPU utilization for multiple EC2 instances side by side. Which JSON widget configuration is the best practice?

hard📝 Application Q8 of 15

AWS - CloudWatch

ACreate separate dashboards for each EC2 instance's CPUUtilization metric

BUse a single metric widget with multiple metrics arrays, each specifying one instance's CPUUtilization

CUse a text widget listing all instance IDs and their CPU values manually updated

DConfigure a single metric widget with a wildcard for InstanceId to aggregate all instances

Step-by-Step Solution

Solution:

Step 1: Understand widget metric arrays
A single metric widget can display multiple metrics side by side by listing each instance's metric separately.
Step 2: Evaluate other options
Separate dashboards reduce visibility; text widgets don't show live metrics; wildcards aggregate metrics, not side-by-side.
Final Answer:
Use a single metric widget with multiple metrics arrays, each specifying one instance's CPUUtilization -> Option B
Quick Check:
Multiple metrics in one widget show side-by-side [OK]

Quick Trick: List multiple metrics in one widget for side-by-side display [OK]

Common Mistakes:

MISTAKES

Creating multiple dashboards instead of one
Using text widgets for dynamic metrics
Using wildcards that aggregate rather than separate metrics
