CCNA 1 Module 8 Exam

1. What is characteristic of the operation of a Layer 2 switch?

*uses the destination MAC address to determine the specific interface to forward a frame

2 Two newly hired technicians are discussing the implementation of a new LAN. One technician proposes installing a hub. The other technician advises installing a switch. Which statements are true about the differences between a hub and a switch? (Choose two.)

*A switch provides more throughput to hosts on a LAN
*A switch provides a collision-free environment on a LAN.

3. Refer to the exhibit. Forty-eight workstations are connected to a hub. The users are able to connect to the network, but access is very slow. An entry-level technician replaces the 10 Mbps hub with 100 Mbps hub but the problem still exists. What is the most economical way to correct the problem?

*Replace the hub with a switch.

4. Exhibited is a portion of ABC Company internetwork. Which of the connections can be full duplex?

*segments 2, 3, and 4

5 Refer to the exhibit. The switch and the hub have default configurations, and the switch has built its CAM table. Which of the hosts will receive the data when workstation A sends a unicast packet to workstation C?

*workstation C

6 An administrator would like to connect ten workstations on a 192.168.0.0/24 network. The device selected by the administrator must allow connectivity between hosts without sharing bandwidth. Which device would be appropriate?

*switch

7 Which networking devices use the MAC address to make forwarding decisions? (Choose two.)

*bridge
*switch

8 Which devices are primarily used to extend cable segments within a collision domain by regenerating the data signals? (Choose two.)

*repeater
*hub

9 Which devices will create multiple collision domains in an Ethernet network? (Choose two.)

*switch
*router

10 Refer to the exhibit. How many broadcast domains exist in classroom 240?

*1

11 A PC receives a frame. Which situation will cause the NIC on the receiving host to pass the frame contents up the OSI layers to be processed by the PC?

*The destination MAC address of the frame is FFFF.FFFF.FFFF.

12 A network administrator has a multi-floor LAN to monitor and maintain. Through careful monitoring, the administrator has noticed a large amount of broadcast traffic slowing the network. Which device would you use to best solve this problem?

*router

13 What will a bridge do if it receives a frame with a MAC address that is not within the table?

*send frame to all ports except source port

14 Which networking device reduces the size of both collision domains and broadcast domains?

*router

15 What is used to prevent Layer 2 switching loops?

*Spanning-Tree Protocol
