Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
It provides a single entry point for client requests and handles cross-cutting concerns
Why this is correct
The gateway abstracts the backend services and provides centralized management.
- ✗
It replaces the need for service meshes
Why it's wrong here
API gateways and service meshes serve different purposes and can complement each other.
- ✗
It stores application state
Why it's wrong here
State should be stored in databases or caches, not in the API gateway.

It performs service-to-service communication
Why it's wrong here
Service-to-service communication is handled by service mesh or direct calls, not necessarily the API gateway.
