An engineer must deploy the Cisco Webex app to a Windows Virtual Desktop Infrastructure environment by using these settings: - Thin client plugin: Not installed - Call service-enabled user: Media is…

`ENABLEVDI=2` is typically used for specific VDI optimization scenarios that do not require a thin client plugin on the endpoint but still perform some media processing offload, which contradicts the requirement that media is not optimized.

The `ENABLEVDI=0` command-line argument during Cisco Webex app installation explicitly disables VDI-specific media optimization, meaning all media processing occurs directly on the virtual desktop without leveraging any thin client plugin. This configuration aligns with the requirements for 'Media is not optimized' and 'Thin client plugin: Not installed'.

`ALLUSERS=0` determines if the application is installed for the current user only or for all users on the system; it does not control VDI media optimization settings.

`ENABLEVDI=1` typically enables full VDI media optimization, often requiring the corresponding thin client plugin to be installed on the endpoint, which is contrary to the stated requirements.
