200-901 Practice Question: Which TWO statements about REST API design best…
Which TWO statements about REST API design best practices are true? (Choose two.)
⚠ Common exam trap
Cisco often tests the misconception that verbs in URIs (like /getDevices) are acceptable, when in fact REST mandates nouns for resources and HTTP methods for actions, and that avoiding versioning is a shortcut that breaks backward compatibility.
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 nouns for resource endpoints, e.g., /devices instead of /getDevices
RESTful APIs use nouns to represent resources (e.g., /devices) rather than verbs (e.g., /getDevices). This aligns with the uniform interface constraint of REST, where the HTTP method (GET, POST, etc.) defines the action, and the URI identifies the resource. Using nouns keeps the API intuitive, consistent, and scalable.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Avoid API versioning to keep the API simple
Why it's wrong here
Incorrect: Versioning is important for evolution.
- ✗
Include the HTTP method in the URI path, e.g., /getDevices
Why it's wrong here
Incorrect: The HTTP method should be used via the verb, not the path.
- ✗
Always use file-based transfer for large payloads
Why it's wrong here
Incorrect: REST can handle large payloads via streaming or chunking.
- ✓
Use nouns for resource endpoints, e.g., /devices instead of /getDevices
Why this is correct
Correct: Nouns represent resources.
- ✓
Use HTTP methods appropriately: GET for retrieval, POST for creation, etc.
Why this is correct
Correct: This aligns with REST principles.
