200-901 Practice Question: Which two authentication methods are commonly…
Which two authentication methods are commonly used with Cisco APIs? (Choose two.)
⚠ Common exam trap
Cisco often tests the distinction between authentication methods used for API access versus those used for device management or network protocols, so the trap here is confusing SNMPv3 or SSH keys (which are for device CLI/management) with HTTP-based API authentication methods.
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 over HTTPS
Basic Authentication over HTTPS is commonly used with Cisco APIs because it sends a base64-encoded username:password pair in the Authorization header, which is a simple and widely supported method for authenticating REST API requests. Cisco's REST APIs, such as those on DNA Center and Meraki, often accept Basic Auth as a fallback or for legacy integration, though it is less secure than token-based methods.
Answer analysis
Option-by-option breakdown

- ✗
SNMPv3
Why it's wrong here
SNMPv3 is used for SNMP management, not REST APIs.
- ✓
Basic Authentication over HTTPS
Why this is correct
Many Cisco APIs support Basic Auth for initial token acquisition.
- ✗
SSH Key
Why it's wrong here
SSH keys are used for device access, not REST API authentication.
- ✗
RADIUS
Why it's wrong here
RADIUS is for network access authentication, not API calls.
- ✓
API Token (Bearer Token)
Why this is correct
Token-based auth is widely used in Cisco APIs like DNA Center and Meraki.
