    Port Triggering and port forwarding can be used on which port(s)?

    • 80

    • 8080

    • 8088

    • 8888

    Correct Answer(s)
    A. 8080
    A. 8088
    Explanation
    Port triggering and port forwarding can be used on ports 8080 and 8088. These techniques are used to redirect incoming network traffic to specific ports on a local network. Port triggering is a dynamic method where a specific outgoing connection triggers the opening of a specific incoming port, while port forwarding is a static method that permanently redirects incoming traffic from a specific port to a designated device on the network. In this case, both port 8080 and 8088 can be used for port triggering and port forwarding.

    Check all port numbers used by NETBIOS:

    • 135

    • 136

    • 137

    • 138

    • 139

    • 140

    • 141

    • 445

    Correct Answer(s)
    A. 135
    A. 137
    A. 138
    A. 139
    A. 445
    Explanation
    NETBIOS (Network Basic Input/Output System) is a protocol used for communication between computers on a local area network (LAN). The given answer lists the port numbers used by NETBIOS. Port 135 is used for the Remote Procedure Call (RPC) endpoint mapper, which allows clients to inquire about the services available on a server. Ports 137 and 138 are used for the NETBIOS name service, which resolves NetBIOS names to IP addresses. Port 139 is used for file and printer sharing, while port 445 is used for the Server Message Block (SMB) protocol, which enables file sharing and other network services.
