SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
A company is migrating a critical application to AWS using a rehost (lift-and-shift) approach. The application consists of a web tier and a database tier. The company wants to ensure high availability and disaster recovery. Which TWO actions should the company take? (Choose TWO.)
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 web tier across multiple Availability Zones.
The correct answers are B and C. Deploying the web tier across multiple Availability Zones provides high availability within a region. Using Amazon RDS Multi-AZ provides automatic failover for the database, ensuring high availability. Option A is incorrect because Auto Scaling across multiple regions is not typical for a lift-and-shift migration and adds unnecessary complexity; cross-region deployment is more suited for disaster recovery, not high availability within a rehost. Option D is incorrect because RDS read replicas are for scaling read traffic, not for high availability or automatic failover. Option E is incorrect because using a single Availability Zone for the database creates a single point of failure and does not provide high availability.
