200-901 Cisco Platforms and Development Practice Question
A developer is using the Cisco DNA Center API and receives a token. How is this token typically used in subsequent API requests?
⚠ Common exam trap
Cisco often tests the specific header name (X-Auth-Token) versus the more generic Authorization header with Bearer scheme, so the trap here is that candidates familiar with OAuth 2.0 may incorrectly choose Option D, not realizing that Cisco DNA Center uses its own proprietary header for token transmission.
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
✓
In the X-Auth-Token header
The Cisco DNA Center API uses token-based authentication where the token is passed in the X-Auth-Token HTTP header for subsequent requests. This is the standard method specified in the Cisco DNA Center API documentation, ensuring the server can validate the session without relying on cookies or query parameters.
