  • Refer to the exhibit. A network administrator has configured R1 as shown. When the administrator checks the status of the serial interface, the interface is shown as being administratively down. What additional command must be entered on the serial interface of R1 to bring the interface up?

      • IPv6 enable

      • clockrate 128000

      • end

      • no shutdown

        Answers Explanation & Hints:

        By default all router interfaces are shut down. To bring the interfaces up, an administrator must issue the no shutdown command in interface mode.

    1. Refer to the exhibit. The network administrator wants to configure Switch1 to allow SSH connections and prohibit Telnet connections. How should the network administrator change the displayed configuration to satisfy the requirement?

      • Use SSH version 1.

      • Reconfigure the RSA key.

      • Configure SSH on a different line.

      • Modify the transport input command.

    1. Which solution would help a college alleviate network congestion due to collisions?

      • a firewall that connects to two Internet providers

      • a high port density switch

      • a router with two Ethernet ports

      • a router with three Ethernet ports

        Answers Explanation & Hints:

        Switches provide microsegmentation so that one device does not compete for the same Ethernet network bandwidth with another network device, thus practically eliminating collisions. A high port density switch provides very fast connectivity for many devices.

    2. Which two statements are correct with respect to SVI inter-VLAN routing? (Choose two.)

      • Switching packets is faster with SVI.

      • There is no need for a connection to a router.

      • Virtual interfaces support subinterfaces.

      • SVIs can be bundled into EtherChannels.

      • SVIs eliminate the need for a default gateway in the hosts.

        Answers Explanation & Hints:

        The SVI inter-VLAN routing method is faster than other methods. The switch can route the existing VLANs without the need for a router.

    3. Refer to the exhibit. A network administrator is configuring inter-VLAN routing on a network. For now, only one VLAN is being used, but more will be added soon. What is the missing parameter that is shown as the highlighted question mark in the graphic?

      • It identifies the subinterface.

      • It identifies the VLAN number.

      • It identifies the native VLAN number.

      • It identifies the type of encapsulation that is used.

      • It identifies the number of hosts that are allowed on the interface.

        Answers Explanation & Hints:

        The completed command would be encapsulation dot1q 7 . The encapsulation dot1q part of the command enables trunking and identifies the type of trunking to use. The 7 identifies the VLAN number.

    1. Which type of VLAN is used to designate which traffic is untagged when crossing a trunk port?

      • data

      • default

      • native

      • management

        Answers Explanation & Hints:

        A native VLAN is the VLAN that does not receive a VLAN tag in the IEEE 802.1Q frame header. Cisco best practices recommend the use of an unused VLAN (not a data VLAN, the default VLAN of VLAN 1, or the management VLAN) as the native VLAN whenever possible.

    2. A network administrator issues the show vlan brief command while troubleshooting a user support ticket. What output will be displayed?

      • the VLAN assignment and membership for device MAC addresses

      • the VLAN assignment and membership for all switch ports

      • the VLAN assignment and trunking encapsulation

      • the VLAN assignment and native VLAN

        Answers Explanation & Hints:

        The show vlan brief command will provide information displaying the VLAN assignment and membership for all switch ports on a switch.

    3. Open the PT Activity. Perform the tasks in the activity instructions and then answer the question.

    Which message is displayed when 10.10.10.1 is entered into the PC1 Web Browser address bar?

      • Local Server

      • Test Server

      • File Server

      • Cisco Server

    Answers Explanation & Hints:

    Examining the configuration of switch SW1 shows that interface Gi0/1 is not configured as a trunk. Issuing the interface configuration command switchport mode trunk on this interface will enable communications between PC1 and Server1.
