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
✓
Basic Authentication with username and password to obtain a token
Cisco DNA Center uses Basic Authentication to obtain a token by sending a POST request to /dna/system/api/v1/auth/token with a Basic Auth header. The returned token is then used in subsequent API calls.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
OAuth 2.0 client credentials grant
Why it's wrong here
DNA Center does not use OAuth 2.0 for its API authentication.
- ✗
API key in the X-Cisco-Meraki-API-Key header
Why it's wrong here
This is used for Meraki Dashboard API, not DNA Center.
- ✗
Bearer token in the Authorization header directly with no initial authentication
Why it's wrong here
A token must first be obtained using Basic Auth.
- ✓
Basic Authentication with username and password to obtain a token
Why this is correct
Correct. The token is obtained via Basic Auth and then used in subsequent requests.
