SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
Network Topology
A company is migrating a critical database server to Amazon EC2. The root volume (EBS) is configured with DeleteOnTermination=false. After migration, the company needs to ensure that if the EC2 instance fails, a new instance can be quickly launched using the same data. The company takes regular snapshots of the volume. Which statement is correct regarding the root volume's behavior?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The root volume will persist after instance termination and can be attached to another instance.
When DeleteOnTermination is set to false, the root volume persists after the EC2 instance is terminated. This allows the volume to be attached to another instance, enabling quick recovery. Option A is incorrect because the root volume can be used as a boot volume for a new instance when attached. Option B is incorrect because the volume is not automatically deleted; deletion only occurs when DeleteOnTermination is true. Option D is incorrect because snapshots are independent of the DeleteOnTermination setting and are not automatically deleted upon instance termination.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The root volume cannot be used as a boot volume for a new instance.
Why it's wrong here
A preserved root EBS volume can be attached and booted by a new instance, so it can serve as a boot volume. It is tempting because root volumes are tied to their original instance's AMI metadata, and it would be correct only for volumes encrypted with keys unavailable to the new instance.
- ✗
The root volume will be automatically deleted when the instance is terminated.
Why it's wrong here
DeleteOnTermination=false preserves the root EBS volume on termination, so automatic deletion contradicts the configured setting. It is tempting because default root volumes are deleted on termination, and it would be correct had the administrator left DeleteOnTermination at its default true value.
- ✓
The root volume will persist after instance termination and can be attached to another instance.
Why this is correct
With DeleteOnTermination set to false, the EBS root volume survives instance termination, satisfying the requirement that data remains available for a replacement instance. The volume detaches and can be reattached to a new EC2 instance in the same Availability Zone, enabling rapid recovery without restoring from snapshots.
- ✗
Snapshots of the volume will be automatically deleted when the instance is terminated.
Why it's wrong here
Snapshots are independent EBS resources and are never deleted automatically when an instance terminates, regardless of DeleteOnTermination. It is tempting because volume deletion feels linked to snapshot lifecycle, and it would be correct only if a lifecycle policy or manual deletion removed them.
