Answer:
Selective Repeat protocols
Explanation:
It is better to make use of the selective repeat protocol here. From what we have here, there is a high error rate on this channel.
If we had implemented Go back N protocol, the whole N packets would be retransmitted. Much bandwidth would be needed here.
But we are told that bandwidth is limited. So if packet get lost when we implement selective protocol, we would only need less bandwidth since we would retransmit only this packet.

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

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.
