CCSP Practice Question: A company has deployed a mission-critical…

A company has deployed a mission-critical application in the cloud and needs to ensure that it remains available even if an entire cloud region fails. Which architecture pattern should they adopt?

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

✓

Active-passive across regions

(active-passive across regions) is correct because this architecture ensures that if an entire cloud region fails, the passive standby in another region can take over, providing disaster recovery and high availability. Option A (regular backups to a different region) provides data recovery but not immediate failover or service continuity. Option C (vertical scaling within a single region) increases capacity but does not protect against region failure. Option D (horizontal scaling within a single availability zone) improves scalability within a zone but does not address region-level outages.

Answer analysis

Option-by-option breakdown

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

  • ✗

    Regular backups to a different region

    Why it's wrong here

    Backups require restore time and are not for continuous availability.

  • ✓

    Active-passive across regions

    Why this is correct

    Active-passive replicates to another region for failover.

  • ✗

    Vertical scaling within a single region

    Why it's wrong here

    Vertical scaling increases size, not availability across regions.

  • ✗

    Horizontal scaling within a single availability zone

    Why it's wrong here

    Scaling within one AZ does not protect against region failure.
