Which two of the following are valid ways to authenticate to the Cisco DNA Center API?
⚠ Common exam trap
Cisco often tests the distinction between device-level authentication (SNMP, SSH) and API-level authentication (tokens, OAuth 2.0), leading candidates to mistakenly select protocols used for network device management instead of REST API authentication methods.

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
✓
Provide API token in HTTP header
The Cisco DNA Center API uses token-based authentication. After obtaining a token via a POST request to the /dna/system/api/v1/auth/token endpoint with valid credentials, the token must be included in the HTTP header as 'X-Auth-Token: <token>' for all subsequent API requests. This is the standard method for authenticating REST API calls to Cisco DNA Center.

Use SNMP v3

Tokens are obtained via login and passed in headers.
