2. /30
3. /23
4. /27

75. University has a small campus where 25 faculty members are located. The faculty offices and student computers are currently on the same network. The faculty is concerned about students being able to capture packets going across the network and obtain sensitive material. What could a network administrator do to protect faculty network traffic from student connections?

1. Install anti-virus software on the student computers.
2. Remove the student computers from the network and put them on a peer-to-peer network
3. Power down the switches that connect to faculty computers when they are not in use
4. Put the faculty computers in a separate VLAN.

76. A Ethernet switch receives a unicast frame with a destination MAC that is listed in the switch table. What will this switch do with the frame?

1. The switch will forward the frame to a specific port
2. The switch will remove the destination MAC from the switch table
3. The switch will forward the frame to all ports except the port on which it was received
4. The switch will return a copy of the frame out the source port

77. Why was the "show processes" command used on a router before a debug command was entered on it?

1. To view the number of timers that are currently in use
2. To verify the amount of space in flash memory
3. To verify that the CPU utilization is low enough to handle the effects of a debug command
4. To check if the load meter file has enough space left to store the output of the debug command

78. You have just purchased a brand new router and wish to have the router prompt you through the initial configuration commands. Which router mode does this describe?

1. ROM Monitor mode
2. SETUP mode
3. Autoflash mode
4. RXBOOT mode

79. In which circumstance are multiple copies of the same unicast frame likely to be transmitted in the Switched LAN?

1. After broken links are re-established
2. When upper-layer protocols require high reliability
3. In an improperly implemented redundant topology
4. During high traffic periods

80. The network administrator needs to add a switch named PC1 to become the root bridge for a redundant path switched network. What can be done to ensure that PC1 will always assume the role as the root bridge?

1. Configure the switch full-duplex operation and configure the other switches for half-duplex operation
2. Configure the switch so that it has lower priority than other switches in the network
3. Assign the switch a higher MAC address than the other switches in the network have
4. Establish a direct link from the switch to all other switches in the network
