AWS Certified SysOps Administrator – Associate (legacy) — Question 847

A user has configured an EC2 instance in the US-East-1a zone. The user has enabled detailed monitoring of the instance. The user is trying to get the data from
CloudWatch using a CLI. Which of the below mentioned CloudWatch endpoint URLs should the user use?

Answer options

• A. monitoring.us-east-1.amazonaws.com
• B. monitoring.us-east-1-a.amazonaws.com
• C. monitoring.us-east-1a.amazonaws.com
• D. cloudwatch.us-east-1a.amazonaws.com

Correct answer: A

Explanation

CloudWatch endpoints are regional rather than zone-specific, meaning they target the region identifier (us-east-1) instead of the Availability Zone (us-east-1a). The standard endpoint for the CloudWatch monitoring service in the US East (N. Virginia) region is monitoring.us-east-1.amazonaws.com. The other options are incorrect because they mistakenly include the Availability Zone suffix or use an invalid subdomain.
