chapter 7 review

What is the result of segmenting a network with a bridge(switch)? (choose 2 options).

A. To prevent unauthorized Telnet access to a switch port E. It makes smaller collision domains.

What are the three distinct functions of layer 2 switching that increase available bandwidth on the network?

A. Address learning C. Forward and filtering E. Loop avoidance.

Why does the switch in the following illustration have two MAC addresses assigned to the Fast Ethernet 0/1 port in the switch address table?

A. Data from Host C and Host D has been received by the switch port Fast Ethernet 0/1.

17. Layer 2 switching provides which of the following? (choose 4)

A. Hardware-based bridging (ASIC) B. Wire speed C. Low latency D. Low cost.

Which two characteristics apply to layer 2 switches?

A. Increase the number of collision domains. C. Implements VLAN

An Ethernet cable is attached to a PC NIC and then attached to a switch port. The PC power is turned on, and the switch port link LED turns green. The link light indicates what two conditions?

A. Layer 2 communication has been established between the PC and switch E. The layer 1 media is functioning between the PC and switch.

Which three of the following statements about switch microsegmentations are correct?

A. Microsegmentation increases bandwidth availability D. Microsegmentation eliminates collisions. E. Each device on a network segment is connected directly to a switch port.

Your switch has a port status LED that is alternating between green and amber. What could this indicate?

A. The port is experiencing errors.

The system LED is amber on a Cisco switch. What does this mean?

A. The system is malfunctioning.

Which of the following statements is true?

B. A switch creates separate collision domains but one broadcast domain. A router provides a separate broadcast domain for each interface.

You connect a router into a switch port, and the port is not turning orange or green. What steps would you take to troubleshoot this problem? (choose 3)

B. Ensure that the cable from the router to the switch is a straight through cable. E. Ensure that the switch has power F. Reset all the cable.

You need to allow one host to be permitted to attach dynamically to each switch interface. Which two of the following commands must you configure on your catalyst switch to meet this policy?

B. Switch(config-if)#switchport port-security maximum 1 D.Switch(config-if)#switchport port-security violation shutdown.

What are two advantages of layer 2 Ethernet switches over hubs?

B. They filter frames based on MAC address. C. They allow simultaneous frame transmissions.

If a switch receives a frame and the source MAC address is not in the MAC address table but the destination address is, what will the switch do with the frame?

C. Add the source address and port to the MAC address table and forward the frame out the destination port.

Why would a network administrator configure port security on a switch?

C. To prevent unauthorized hosts from accessing the LAN.

What command will display the forward/filter table?

C. show mac address-table

What does a switch do when a frame is received on an interface and the destination hardware address is unknown or not in the filter table?

D. Floods the frame out all ports except the port the frame was received on.

You need to configure a Catalyst switch so it can be managed remotely. Which of the following would you use to accomplish this task?

E. Switch(config)#ip default-gateway 192.168.10.254
