SAP-C02 Design for New Solutions Practice Question
A company is migrating a legacy application to AWS. The application consists of several components that communicate via TCP. The solutions architect must design a solution that minimizes operational overhead and provides high availability. Which TWO strategies should be used?
⚠ Common exam trap
Test-takers frequently confuse high availability with data persistence, incorrectly choosing instance store volumes (Option A) for persistence, or assume that Spot Instances (Option C) can be used for all compute resources despite their interruption risk, overlooking the need for reliable TCP communication in a production migration.
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
✓
Use managed services like Amazon RDS and Amazon ElastiCache to reduce operational overhead.
Using managed services like Amazon RDS and Amazon ElastiCache offloads administrative tasks such as patching, backups, and replication setup, significantly reducing operational overhead. Option E is correct because an Application Load Balancer (ALB) distributes incoming TCP traffic across multiple EC2 instances in different Availability Zones, providing high availability and fault tolerance for the application components.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use instance store volumes for data persistence.
Why it's wrong here
Instance store is ephemeral; use EBS or RDS for persistence.
- ✓
Use managed services like Amazon RDS and Amazon ElastiCache to reduce operational overhead.
Why this is correct
Managed services reduce overhead and provide HA out-of-the-box.
- ✗
Use Spot Instances for all compute resources.
Why it's wrong here
Spot Instances can be terminated, not suitable for critical production.
- ✗
Use VPC Peering to connect components.
Why it's wrong here
VPC Peering provides connectivity but not HA.
- ✓
Use an Application Load Balancer to distribute traffic across multiple EC2 instances.
Why this is correct
ALB provides high availability and decoupling.
