Which two steps does a Citrix Engineer need to take to enable shadowing in XenDesktop? (Choose two.)

Windows Remote Assistance is the underlying Windows feature that Citrix leverages for session shadowing; without it enabled, the shadowing request cannot be initiated or accepted.

Enable-PSRemoting configures Windows PowerShell remoting over WinRM and is unrelated to the RDP-based shadowing mechanism used in XenDesktop.

Windows Remote Management (WinRM) is a management protocol for PowerShell remoting and scripting, not a prerequisite for Citrix session shadowing.

Disabling UAC is not required for shadowing; UAC controls elevation prompts and does not gate the Remote Assistance functionality needed for shadowing.

Port 3389 is the default RDP port used by the shadowing connection; if this port is blocked by a firewall, the administrator's client cannot establish the remote view of the user session.
