SAP-C02 Design for New Solutions Practice Question
A company is designing a new microservices-based application on AWS. They want to ensure that services can discover each other dynamically and that traffic can be load balanced across multiple Availability Zones. Which AWS service should they use for service discovery?
⚠ Common exam trap
Watch out — candidates often confuse Route 53 private hosted zones (which provide static DNS resolution) with a dynamic service discovery solution, overlooking that Cloud Map is specifically designed for dynamic registration and health-aware endpoint resolution.

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
✓
AWS Cloud Map
AWS Cloud Map is a cloud resource discovery service that allows microservices to dynamically register their endpoints (IP addresses, ports) and discover each other via DNS or API calls. It integrates with Amazon Route 53 auto-naming and health checks, enabling load-balanced traffic across multiple Availability Zones by returning healthy, available endpoints. This makes it the correct choice for dynamic service discovery in a microservices architecture.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS Service Catalog
Why it's wrong here
AWS Service Catalog is used to create and manage approved IT services, not for service discovery.
- ✗
Amazon Route 53 private hosted zones
Why it's wrong here
Route 53 private hosted zones are used for DNS resolution within a VPC but do not provide dynamic service registration and health checking out of the box.
- ✗
AWS Systems Manager Parameter Store
Why it's wrong here
Parameter Store is for configuration management, not dynamic service discovery.
- ✓
AWS Cloud Map
Why this is correct
AWS Cloud Map provides service discovery with health checks and integration with Route 53.
