350-601 Network Practice Question
Which feature in NX-OS allows for direct API calls to the switch for automation purposes?
⚠ Common exam trap
Cisco often tests the distinction between a direct API (NX-API) and automation tools (Python, Bash) that may use APIs indirectly, leading candidates to confuse scripting languages or shell access with the actual API endpoint.
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
✓
NX-API
NX-API (option A) is the correct answer because it is the native NX-OS feature that exposes a RESTful API interface, allowing direct HTTP/HTTPS calls (e.g., GET, POST, PUT, DELETE) to the switch for automation and programmability. This enables tools like Ansible, Postman, or custom scripts to send structured data (JSON/XML) to configure, monitor, and manage the switch without requiring CLI parsing or SSH sessions.
