Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The Glue job failed before writing any log events to CloudWatch.
StoredBytes: 0 means no log events were stored, likely because the job failed before writing any logs or logging was not enabled. Option A is wrong because logs are not expired; they were never written. Option B is wrong because the stream exists. Option D is wrong because the command retrieved the latest stream.
