Question

Explanation

This question tests the ability to construct a Python function using the Cisco vManage REST API to retrieve the list of devices participating in an SD-WAN overlay network. It validates knowledge of the correct API endpoint, session handling, authentication flow, and JSON response parsing.

Approach. The correct approach follows the standard vManage REST API pattern: (1) create a persistent session using requests.Session(), (2) authenticate by POSTing credentials to /j_security_check with j_username and j_password form fields, (3) optionally fetch a CSRF token via GET /dataservice/client/token and attach it as the X-XSRF-TOKEN header, (4) call GET /dataservice/device to retrieve device inventory, and (5) parse the response with .json()['data'] since vManage wraps its payload in a top-level data key. The verify=False flag is typically required because vManage uses self-signed TLS certificates. The function should return the list extracted from response.json()['data'], which contains each device's system-IP, hostname, reachability status, and device type.

Concept tested. Cisco vManage SD-WAN REST API usage - specifically the device inventory endpoint (GET /dataservice/device), session-based authentication via /j_security_check, CSRF token handling, and correct JSON response extraction using the data key. This maps to Cisco DevNet Associate/Professional and CCNP SD-WAN exam objectives around programmability of SD-WAN controllers.
