Question

A Windows user contacted the help desk with a problem that requires the technician to connect to the remote computer using Remote Assistance to view a very detailed and cryptic error message on the user’s desktop. Each attempt the technician makes to connect to the remote computer results in a message stating the connection was refused.
Which of the following protocol and port number combinations should be opened on the remote computer’s firewall to allow this connection?

Group of answer choices

1. SSH, port 22
2. Telnet, port 23
3. DNS, port 53
4. RDP, port 3389

Answer 1

Answer:

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

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.
