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
✓
s3:PutObject
Options A and E are correct. A Glue job requires s3:GetObject to read input data from S3 and s3:PutObject to write output data to S3. Option B (kms:Decrypt) is only needed if the S3 objects are encrypted with KMS. Option C (dynamodb:GetItem) is not relevant unless the job accesses DynamoDB. Option D (glue:StartJobRun) is not needed for the job's execution itself; it is used to start a job run.
