200-901 Understanding and Using APIs Practice Question

Which three statements are true about the Cisco Catalyst Center (formerly DNA Center) intent API? (Choose three.)

⚠ Common exam trap

Cisco often tests the distinction between Catalyst Center and Meraki APIs, so the trap here is confusing the authentication method (token-based vs. API key) and assuming only GET/POST are used, when in fact RESTful APIs support full CRUD operations.

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

The base URL for the API includes the Catalyst Center hostname and port.

The Cisco Catalyst Center intent API uses a base URL that includes the Catalyst Center hostname (or IP address) and port (typically 443 for HTTPS). For example, the base URL is formatted as `https://<catalyst-center-hostname>:443/dna/intent/api/v1/`. This is required to direct API calls to the specific Catalyst Center instance.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • The base URL for the API includes the Catalyst Center hostname and port.

    Why this is correct

    Yes, e.g., https://<host>:<port>/dna/intent/...

  • Authentication is done by sending a POST request to /dna/system/api/v1/auth/token with credentials.

    Why this is correct

    Yes, to obtain a token.

  • The API uses only GET and POST methods.

    Why it's wrong here

    It uses GET, POST, PUT, DELETE, etc.

  • It uses RESTful principles and returns JSON responses.

    Why this is correct

    Yes, it is a REST API with JSON.

  • It requires an API key passed in the X-Cisco-Meraki-API-Key header.

    Why it's wrong here

    That is for Meraki, not Catalyst Center.
