AWS Certified SysOps Administrator – Associate (legacy) — Question 767

You can create a CloudWatch alarm that watches a single metric. The alarm performs one or more actions based on the value of the metric relative to a threshold over a number of time periods. Which of the following states is possible for the CloudWatch alarm?

Answer options

• A. OK
• B. ALERT
• C. THRESHOLD
• D. ERROR

Correct answer: A

Explanation

Amazon CloudWatch alarms can only be in one of three states: OK, ALARM, or INSUFFICIENT_DATA. Therefore, 'OK' is the only valid state listed in the options. States such as ALERT, THRESHOLD, and ERROR are not recognized by CloudWatch.
