AWS Certified SysOps Administrator – Associate (legacy) — Question 186

A user has launched an EBS backed instance. The user started the instance at 9 AM in the morning. Between 9 AM to 10 AM, the user is testing some script.
Thus, he stopped the instance twice and restarted it. In the same hour the user rebooted the instance once. For how many instance hours will AWS charge the user?

Answer options

• A. 3 hours
• B. 4 hours
• C. 2 hours
• D. 1 hour

Correct answer: A

Explanation

AWS charges for instance hours from the moment the instance is started until it is stopped. In this case, the instance was started at 9 AM and remained running until the user stopped it, accumulating 3 instance hours, including the time spent during restarts and reboots. The other options do not account for the total running time correctly.
