CV0-004 Practice Question: A cloud architect is designing a deployment for a…
A cloud architect is designing a deployment for a multi-tier application that must meet compliance requirements for data residency. The application consists of a web tier, application tier, and database tier. Which TWO deployment strategies should the architect consider to ensure data remains in a specific geographic region while maintaining high availability?
⚠ Common exam trap
CompTIA often tests the distinction between 'high availability' and 'disaster recovery' — candidates mistakenly choose multi-region deployment for high availability, but that violates data residency, while the correct answer uses multiple AZs within a single region to satisfy both constraints.
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 across multiple availability zones in the same region
Deploying across multiple Availability Zones (AZs) within the same region ensures that application components remain within the geographic boundary required for data residency, while providing high availability through fault isolation. If one AZ fails, traffic is automatically routed to healthy instances in other AZs, maintaining uptime without leaving the region.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Set up a VPN to a neighboring region
Why it's wrong here
Would route data outside the required region.
- ✓
Deploy across multiple availability zones in the same region
Why this is correct
Keeps data in region and provides HA.
- ✗
Deploy in a single availability zone
Why it's wrong here
Single point of failure, not highly available.
- ✓
Use regional load balancers
Why this is correct
Keeps traffic within the region.
- ✗
Deploy across multiple regions
Why it's wrong here
May violate data residency requirements.
