200-901 Practice Question: A developer uses Cisco Intersight API to manage…
A developer uses Cisco Intersight API to manage UCS servers. Which authentication method is required for Intersight API calls?
⚠ Common exam trap
Cisco often tests the distinction between web UI authentication (session cookies) and API authentication (HMAC keys), and candidates mistakenly choose session cookies because they are familiar from the Intersight web interface, forgetting that API calls require a different, stateless mechanism.

Correct answer & explanation
✓
API key with HMAC signature
Cisco Intersight API requires API key authentication with HMAC (Hash-Based Message Authentication Code) signing for all REST API calls. The developer generates an API key pair (private and public) in the Intersight GUI, then uses the private key to create an HMAC-SHA256 signature over the request headers and payload. This signature is included in the Authorization header, ensuring request integrity and non-repudiation without transmitting the secret key over the network.
