After implementing these networks, the administrator realizes there has been a mistake. Which of the following BEST describes the mistake?

   • 10.0.10.0/24 is not valid because 0 in the second octet cannot be used in the network portion of the IP address.
   • 127.0.0.0/24 is the reserved loopback network and cannot be used for host networks.
   • 172.16.0.0/24 is the reserved multicast network and cannot be used for host networks.
   • 192.168.255.0/24 is not valid because 255 in the third octet cannot be used in the network portion of the IP address.

8. A company is redesigning its office to remove the divider walls between desks and create an open collaboration area. All network cables are run through the divider walls, and a new wireless network will be installed. Which of the following sets of documents will need to be revised based on the new configuration?

   • 192.168.11.255
   • 192.168.255.255

10. A senior technician is reconfiguring the company’s firewall because a number of additional devices have been added to the network. The company has acquired a new VoIP phone system, and a group of junior technicians has set up an experimental lab with access to the Internet. Management has given the team latitude for research and development, but would like the company network to be secure and the performance to remain consistent with existing baselines. Which of the following would be the BEST method to reconfigure the network?

    • The technician should put the junior team’s lab in a VLAN and the phone system in the DMZ.
    • The technician should put the junior team’s lab in a DMZ and the phone system in a VLAN.
    • The technician should put the junior team’s lab in the LAN and the phone system in the WAN.
    • The technician should put the junior team’s lab in the WAN and the phone system in a WLAN

11. A network technician discovers there is no connectivity on a T1 line even though the cable connection appears to be in place. The router shows there is no active connection on the port. The issue is occurring between the demarcation point and the router port. The router cable tests fine and is terminated at the demarcation panel. Which of the following tools should be used to fix the issue?

    • Crimper
    • OTDR
    • Loopback adapter

12. Which of the following properties should be configured to extend logical network separation on an uplink interface to a second switch?
