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

✓

Review the CloudWatch logs for the replication instance and task.

The first step is to check the CloudWatch logs for DMS to find detailed error messages. Option A is wrong because restarting without investigation may lead to the same error. Option B is wrong because modifying table mappings may not be the issue. Option C is wrong because creating a new task without understanding the failure is inefficient.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    Restart the replication task with a different migration type.

    Why it's wrong here

    Changing migration type may not address the underlying issue.

  • ✗

    Modify the table mappings to exclude all tables.

    Why it's wrong here

    Excluding tables would not help identify the failure.

  • ✗

    Create a new replication task with the same settings.

    Why it's wrong here

    The new task would likely fail with the same error.

  • ✓

    Review the CloudWatch logs for the replication instance and task.

    Why this is correct

    CloudWatch logs provide detailed error messages for troubleshooting.
