Answer 1

To enable the use of Net BIOS through a firewall, you should open ports 137 through 139.

Step-by-step explanation:

The correct answer is option A) 137 through 139. NetBIOS (Network Basic Input/Output System) uses these ports to enable communication between computers on a local network. Port 137 is used for NetBIOS Name Resolution, port 138 is used for NetBIOS Datagram Service, and port 139 is used for NetBIOS Session Service.
