   A large enterprise is planning to automate network changes across both campus and WAN. The team has decided to use Catalyst Center for campus devices and SD-WAN Manager for WAN devices. The team wants to create a single automation workflow that triggers a configuration change on a campus switch and a policy change on a WAN edge router. What is the best way to implement this workflow?

   • AUse the SD-WAN Manager API to make both changes because it can manage campus devices.
   • BUse a single API call to a unified endpoint that manages both platforms.
   • CCreate two separate scripts: one that calls the Catalyst Center API and one that calls the SD-WAN Manager API, and run them sequentially.
   • DUse the Catalyst Center API to make both changes because it can manage WAN devices.

   An organization is migrating from a legacy network management system to Catalyst Center. The automation team has written a script that uses the Catalyst Center API to retrieve device inventory and then push a new configuration to all switches. The script works in the lab but fails in production with a 401 error on the first API call. The team has verified that the credentials are correct. What is the most likely cause?

   • AThe production Catalyst Center has a different API base path than the lab.
   • BThe script is using the wrong authentication method; production requires a certificate instead of a token.
   • CThe production Catalyst Center has a different API version, and the script is using an outdated endpoint.
   • DThe script is not sending the Authorization header with the token in production.

   A network engineer is building a script that uses the SD-WAN Manager API to retrieve the configuration of all devices in a specific site. The engineer has authenticated and can retrieve the device list. However, when the script tries to retrieve the configuration for each device using GET /dataservice/device/{deviceId}?config=true, it receives an empty response for some devices. What is the most likely reason?

   • AThe script is using an incorrect deviceId for those devices.
   • BThose devices are vSmart controllers, which do not expose configuration via the API.
   • CThose devices have not been synchronized with vManage.
   • DThose devices are not reachable from vManage at the moment.

   A network administrator wants to use the SD-WAN Manager API to automate the deployment of a new VPN policy across all WAN edges. The administrator needs to authenticate to the API. Which authentication method is supported by SD-WAN Manager?

   • ABasic authentication with username and password in each request
   • BOAuth2 client credentials to obtain a token, then use the token in the X-XSRF-TOKEN header for subsequent requests
   • CCertificate-based authentication using a client certificate
   • DAPI key generated from the SD-WAN Manager UI and passed in the header
