Answer 2

Option 4 i.e., RDP, port 3389.

Step-by-step explanation:

The User has informed the helpdesk with such an issue that involves the specialist to link to the remote server utilizing Remote Assist to access the user's screen with a quite informative and ambiguous error. Every attempt made by the technician to link to the virtual server outcomes in a message saying that the link has been denied.

So the combinations of RDP and port 3389 would be enabled on the remote computer’s firewall to allow this connection.
