200-901 Practice Question: Which THREE of the following are key…
Which THREE of the following are key characteristics of a RESTful API? (Choose three.)
⚠ Common exam trap
Cisco often tests the distinction between REST and SOAP, and the trap here is that candidates may confuse REST's statelessness with the need for session cookies (stateful behavior) or incorrectly associate REST with SOAP due to both being web service technologies.
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
✓
Resource-based URLs
RESTful APIs use resource-based URLs (e.g., /users/123) to uniquely identify resources, which aligns with the uniform interface constraint of REST. This design makes the API intuitive and self-descriptive, allowing clients to interact with resources directly via the URL structure.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Resource-based URLs
Why this is correct
Resources are identified by URIs.
- ✓
Stateless communication
Why this is correct
Each request from client to server must contain all necessary information.
- ✗
Uses SOAP protocol
Why it's wrong here
SOAP is a separate protocol, not characteristic of REST.
- ✗
Relies on session cookies for state
Why it's wrong here
REST APIs should be stateless; cookies introduce state.
- ✓
Uses standard HTTP methods (GET, POST, PUT, DELETE)
Why this is correct
REST APIs leverage HTTP methods for CRUD operations.
