AWS Certified Solutions Architect – Professional — Question 169

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

Correct answer: C

Explanation

The correct endpoint is monitoring.us-east-1.amazonaws.com, which is the regional endpoint for CloudWatch in the US-East-1 region. The other options either include the availability zone 'a' or have incorrect formatting; CloudWatch URLs do not require the availability zone in their endpoints.
