Question

A network engineer is developing a Python script to configure multiple Nexus 9000 switches through the NX-API REST interface. The script must authenticate once and reuse the session for subsequent configuration calls to avoid re-sending credentials with every request. Which mechanism should the engineer use to maintain the authenticated session across multiple NX-API REST calls?

Accepted Answer

Store the session cookie returned by the aaaLogin request and include it in the HTTP header of subsequent requests

Answer

Send the username and password as URL query parameters on every API call to re-establish trust

Answer

Enable SNMPv3 credentials so the REST calls inherit the SNMP engine ID as a session identifier

Answer

Configure a static pre-shared key in the feature nxapi settings and embed it in each JSON payload
