Watch out for

Common High Availability exam traps

▸Answering from memory before reading the full scenario.
▸Missing a constraint such as cost, availability, security, scope or command context.
▸Choosing a broad answer when the question asks for the most specific fix.
▸Ignoring why the wrong options are tempting.

A company is designing a new microservices architecture on AWS. They need a solution for service discovery that allows services to register themselves and discover other services dynamically. The solution must be highly available and integrated with AWS-native services. Which AWS service should they use?

Trap 1: Amazon ECS Service Discovery

ECS Service Discovery is built on AWS Cloud Map; Cloud Map is the recommended service for this use case.

Trap 2: Application Load Balancer (ALB)

ALB distributes traffic but does not provide service discovery for multiple service types.

Trap 3: Amazon Route 53 private hosted zones

Route 53 private hosted zones provide DNS resolution but not automatic service registration or health-based deregistration.

A
Amazon ECS Service Discovery
Why wrong: ECS Service Discovery is built on AWS Cloud Map; Cloud Map is the recommended service for this use case.
B
Application Load Balancer (ALB)
Why wrong: ALB distributes traffic but does not provide service discovery for multiple service types.
C
AWS Cloud Map
Cloud Map is a service discovery service that allows resources to register and discover each other, with health checks.
D
Amazon Route 53 private hosted zones
Why wrong: Route 53 private hosted zones provide DNS resolution but not automatic service registration or health-based deregistration.
