200-901 Cisco Platforms and Development Practice Question
A developer is creating a Python script to interact with a Cisco NX-OS device using the NX-API. The script will send HTTP requests to the device's management IP. Which command must be configured on the NX-OS device to enable the NX-API feature?
⚠ Common exam trap
The trap here is assuming that enabling the generic HTTP server is sufficient for NX-API, when a specific feature command is required.
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
✓
feature nxapi
On Cisco NX-OS, the NX-API is enabled by entering the global configuration command 'feature nxapi'. This activates the API and allows the device to accept HTTP/HTTPS requests on the management interface. Other commands like 'ip http server' do not provide the NX-API functionality, so they cannot be used as substitutes.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
ip http server
Why it's wrong here
The 'ip http server' command enables the traditional HTTP server for web-based management, but it does not enable the NX-API. While NX-API uses HTTP/HTTPS transport, it requires the specific 'feature nxapi' command. Using only 'ip http server' would not provide the JSON-RPC or REST API capabilities needed.
- ✗
nxapi enable
Why it's wrong here
There is no command 'nxapi enable' in NX-OS. The correct syntax uses the 'feature' keyword to turn on the NX-API functionality. Attempting this command would result in an error, and the API would remain disabled, preventing the script from communicating with the device.
- ✗
feature http-server
Why it's wrong here
The command 'feature http-server' does not exist in NX-OS for enabling NX-API. The correct feature name is 'nxapi'. This option is a distractor that might confuse those familiar with other platforms. Without the correct feature enabled, the NX-API endpoints will not be available.
- ✓
feature nxapi
Why this is correct
The command 'feature nxapi' enables the NX-API feature on Cisco NX-OS devices. Without this command, the device does not listen for HTTP/HTTPS API requests. This is the correct and required configuration step to allow programmatic access via the NX-API.
