PAS-C01 Operations and Maintenance Practice Question

A company runs SAP on AWS and has configured a cross-region DR strategy using Amazon EBS snapshots. The DR region is in us-west-2. After a region-wide outage, the administrator attempts to restore the snapshots but finds the latest snapshot is incomplete. What is the most likely cause?

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

✓

The latest snapshot copy had not completed before the outage

Cross-region snapshot copies are asynchronous and may fail if the source region becomes unavailable. Option A is wrong because IAM does not prevent copying. Option C is wrong because KMS keys can be used cross-region with proper configuration. Option D is wrong because the snapshot ID would not become invalid.

Answer analysis

Option-by-option breakdown

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

  • ✗

    The IAM role used for copying snapshots does not have permissions

    Why it's wrong here

    If permissions were missing, the copy would not start at all.

  • ✓

    The latest snapshot copy had not completed before the outage

    Why this is correct

    Cross-region copy takes time; if outage occurs during copy, snapshot may be partial.

  • ✗

    The snapshots are encrypted with a KMS key that is not available in us-west-2

    Why it's wrong here

    KMS keys can be replicated to other regions.

  • ✗

    The snapshot ID used for recovery is not valid

    Why it's wrong here

    Snapshot IDs remain valid unless deleted.
