DEA-C01 Data Store Management Practice Question
A company is using Amazon S3 to store sensitive data. They need to automatically transition objects to S3 Glacier Deep Archive after 90 days and delete them after 7 years. Which S3 lifecycle configuration action should be used?
⚠ Common exam trap
Candidates often confuse 'Expiration' with 'Transition', thinking that deleting objects after a period is the same as moving them to a colder storage class, but expiration deletes data while transition preserves it in a different tier.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Transition
The S3 lifecycle 'Transition' action is specifically designed to move objects between storage classes. To automatically move objects to S3 Glacier Deep Archive after 90 days, you define a transition rule with a 'Days' value of 90 and a 'StorageClass' of 'DEEP_ARCHIVE'. This action directly meets the requirement for transitioning data to a colder storage tier.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Transition
Why this is correct
Transition moves objects to another storage class based on age.
- ✗
AbortIncompleteMultipartUpload
Why it's wrong here
This action is used to abort incomplete multipart uploads, not to transition objects.
- ✗
Expiration
Why it's wrong here
Expiration only deletes objects, it does not transition them to another storage class.
- ✗
NoncurrentVersionExpiration
Why it's wrong here
This applies to noncurrent versions of objects, not to transitioning current versions.
