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

✓

Use the AWS CLI or Console to initiate a point-in-time restore specifying the desired timestamp.

To restore a DynamoDB table to a point in time, the table must have point-in-time recovery (PITR) enabled. If it is enabled, you can use the AWS CLI or Console to initiate a point-in-time restore by specifying the desired timestamp. Option A is incorrect because a manual backup is not required; PITR uses continuous backups. Option B is incorrect because AWS Backup is not necessary; DynamoDB PITR is sufficient. Option C is incorrect because PITR does not require any on-demand backups; it relies on continuous backups.

Answer analysis

Option-by-option breakdown

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

  • ✗

    Create a manual backup of the table first.

    Why it's wrong here

    PITR eliminates the need for manual backups.

  • ✗

    Enable AWS Backup to schedule automatic backups.

    Why it's wrong here

    DynamoDB PITR is independent of AWS Backup.

  • ✗

    Ensure the table has at least one on-demand backup.

    Why it's wrong here

    PITR uses continuous backups, not on-demand.

  • ✓

    Use the AWS CLI or Console to initiate a point-in-time restore specifying the desired timestamp.

    Why this is correct

    PITR is enabled, so restore is straightforward.
