200-901 Cisco Platforms and Development Practice Question
This 200-901 practice question tests your understanding of cisco platforms and development. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A developer is using the Cisco DNA Center API and receives a token. How is this token typically used in subsequent API requests?
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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
As a query parameter named token
Why it's wrong here
Tokens are not passed as query parameters.
- ✗
In the request body
Why it's wrong here
Token is in the header, not body.
- ✓
In the X-Auth-Token header
Why this is correct
This is the correct header for DNA Center API requests.

Why it's wrong here
DNA Center uses X-Auth-Token, not Bearer.
Common exam traps
Common exam trap: answer the scenario, not the keyword
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.
Detailed technical explanation
How to think about this question
Under the hood, the token is a JSON Web Token (JWT) issued by the DNA Center authentication endpoint (e.g., POST /dna/system/api/v1/auth/token). The token contains claims like the user's roles and expiration time, and the server verifies it on each request by decoding the JWT signature. In a real-world scenario, if the token expires, the developer must re-authenticate to obtain a new token, as the API returns a 401 Unauthorized status for expired tokens.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A junior network technician can log in to a core router but cannot reach the enable prompt or configuration mode. The AAA server is authenticating the login — but the authorisation policy only grants privilege level 1, not 15. Authentication (who you are) is working; authorisation (what you can do) is not.
