Cloud Digital Leader Fundamental Cloud Concepts Practice Question
A company is designing a disaster recovery strategy for a critical application. They need to ensure that if an entire Google Cloud region becomes unavailable, the application can still serve traffic from another region with minimal data loss. Which TWO strategies should they implement? (Choose 2.)
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
✓
Deploy the application in multiple regions
Multi-region deployment across at least two regions provides region-level failure protection. To minimize data loss, synchronous replication (e.g., using Cloud Spanner or multi-region Cloud Storage) ensures data consistency across regions.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Deploy the application in multiple regions
Why this is correct
Multi-region deployment ensures availability if one region fails.
- ✓
Use synchronous replication for the database
Why this is correct
Synchronous replication ensures no data loss across regions.
- ✗
Deploy the application in multiple zones within a single region
Why it's wrong here
This protects against zone failure but not region failure.
- ✗
Use asynchronous replication for the database
Why it's wrong here
Asynchronous replication may cause data loss during failover.
- ✗
Use a single load balancer
Why it's wrong here
A single load balancer does not provide region-level redundancy.
