AWS Certified SysOps Administrator – Associate (legacy) — Question 463

In EC2, what happens to the data in an instance store if an instance reboots (either intentionally or unintentionally)?

Answer options

• A. Data is partially present in the instance store.
• B. Data persists in the instance store.
• C. Data is deleted from the instance store for security reasons.
• D. Data in the instance store will be lost.

Correct answer: B

Explanation

Data stored in an EC2 instance store persists during an instance reboot, whether it is initiated intentionally or occurs unexpectedly. In contrast, the data is lost if the instance is stopped, terminated, or suffers a hardware failure. Thus, a simple reboot does not cause data loss on instance store volumes.
