AWS Certified SysOps Administrator – Associate (legacy) — Question 243

A user has setup a billing alarm using CloudWatch for $200. The usage of AWS exceeded $200 after some days. The user wants to increase the limit from $200 to $400? What should the user do?

Answer options

• A. Create a new alarm of $400 and link it with the first alarm
• B. It is not possible to modify the alarm once it has crossed the usage limit
• C. Update the alarm to set the limit at $400 instead of $200
• D. Create a new alarm for the additional $200 amount

Correct answer: C

Explanation

The correct answer is C because existing CloudWatch alarms can be updated to change their thresholds. Option A suggests creating a new alarm, which is unnecessary, and option B is incorrect because it is possible to modify alarms. Option D is also not ideal since adjusting the existing alarm is the more straightforward approach.
