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

It is a Single-AZ MySQL DB instance.

The output shows engine=mysql, MultiAZ=false, SecondaryAvailabilityZone=null, and DBInstanceStatus=available. This indicates a Single-AZ MySQL DB instance, not a Multi-AZ deployment, not Aurora, and not in a failed state. Therefore, option D is correct.

Answer analysis

Option-by-option breakdown

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

  • It is an Amazon Aurora MySQL-Compatible DB cluster.

    Why it's wrong here

    The engine is mysql, not aurora.

  • It is a MySQL DB instance that is currently in a failed state.

    Why it's wrong here

    DBInstanceStatus is 'available', so it is not failed.

  • It is a Multi-AZ DB instance with a standby in a different AZ.

    Why it's wrong here

    MultiAZ is false, so it is not Multi-AZ.

  • It is a Single-AZ MySQL DB instance.

    Why this is correct

    MultiAZ is false and SecondaryAvailabilityZone is null, confirming Single-AZ.
