Explanation

NX-API CLI JSON-RPC: Creating an SVI

The correct answers are A and C (the question requires two; "A" alone appears to be a display artifact).

Why A is correct: The JSON-RPC interface requires the Content-Type header to be application/json-rpc - not plain application/json. This tells the Nexus switch to route the request through the JSON-RPC endpoint rather than the REST API endpoint.

Why C is correct: For configuration commands over JSON-RPC, the correct method is cli_conf, and the parameter key is command. Option C correctly uses cli_conf with a semicolon-separated command string to enter config mode and create the VLAN interface in a single payload.

Why B is wrong: Using content-type: application/json is for the NX-API REST interface, not JSON-RPC - the switch will reject or misroute the request.

Why D is wrong: The cli method is for show/exec (read-only) commands, not configuration; its parameter key is cmd. Option D incorrectly uses cli with cmd for config operations - the right combination for configuration is cli_conf with command.

Memory tip: Think RPC → -rpc in the header, and conf → cli_conf in the method. If you're configuring, both the header suffix and the method name must say it explicitly.
