B. that's what the official AWS docs and exam guides both suggest for this scenario. TTL attribute plus enabling the feature means no scripts needed. I saw similar on practice tests, pretty sure that's what they're after.
Why not just use TTL? Option B mentions enabling it with an expiration attribute, which sounds like the built-in way.
B had something like this in a mock and TTL is the easiest way to handle it.
B tbh, DynamoDB TTL makes this super easy without extra scripts or weird table tricks.
D imo, matches what I've seen in similar practice sets. Question is really clear about rollback needs.
Be respectful. No spam.
