AWS Certified SysOps Administrator – Associate (legacy) — Question 185

When an EC2 EBS-backed (EBS root) instance is stopped, what happens to the data on any ephemeral store volumes?

Answer options

• A. Data will be deleted and win no longer be accessible
• B. Data is automatically saved in an EBS volume.
• C. Data is automatically saved as an EBS snapshot
• D. Data is unavailable until the instance is restarted

Correct answer: A

Explanation

When an EC2 EBS-backed instance is stopped, all data on ephemeral store volumes is lost, which is why option A is correct. Options B and C are incorrect because ephemeral storage does not automatically save data to EBS volumes or snapshots. Option D is also incorrect since the data is not just unavailable; it is permanently deleted.
