    The correct answer states that the ACL should be applied to all vty lines in the in direction to prevent an unwanted user from connecting to an unsecured port. This means that the ACL should be configured to control Telnet traffic that is destined to the router itself, specifically on the virtual terminal lines (vty lines). By applying the ACL in the in direction on all vty lines, any Telnet traffic coming into the router will be filtered and unwanted users will be prevented from accessing the router through an unsecured port.

    Which three switch security commands are required to enable port security on a portso that it will dynamically learn a single MAC address and disable the port if a host with any other MAC address is connected? (Choose three.)

    • Switchport mode access

    • Switchport mode trunk

    • Switchportport-security

    • Switchport port-security maximum 2

    • Switchportport-security mac-address sticky

    • Switchport port-security mac-addressmac-address

    Correct Answer(s)
    A. Switchport mode access
    A. Switchportport-security
    A. Switchportport-security mac-address sticky
    Explanation
    The first command, "switchport mode access," is required to configure the port as an access port, which means it will only accept traffic from a single VLAN. This is necessary for port security to work properly.

    The second command, "switchportport-security," is required to enable port security on the port. This command allows the switch to monitor the MAC addresses of devices connected to the port.

    The third command, "switchportport-security mac-address sticky," is required to enable sticky MAC address learning on the port. This means that the switch will dynamically learn the MAC address of the first device connected to the port and only allow that MAC address to communicate through the port. If any other device with a different MAC address is connected, the port will be disabled.

    These three commands together enable port security on the port, allowing it to dynamically learn a single MAC address and disable the port if any other MAC address is connected.
