CCNA 1 Module 8 Exam Result

1. What is characteristic of the operation of a Layer 2 switch?
• forwards data based on logical addressing
• duplicates the electrical signal of each frame to every port
• learns the port assigned to a host by examining the destination MAC address
• 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 hub operates at Layer 2 of the OSI model.
• A hub reduces the number of collisions on a LAN.
• A hub works at a higher OSI model layer than a switch.
• A switch provides more throughput to hosts on a LAN
• A switch provides a collision-free environment on a LAN.
• The number of collisions on a LAN are the same whether a hub or a switch is used.

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.

• Replace the hub with a router.

• Replace the hub with a 1 Gbps hub.

• Replace the hub with a 10 Mbps fiber hub.

4.

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

• segments 1 and 2

• segment 2

• segments 3 and 4

• segments 2, 3, and 4

• segments 1, 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

• workstations B and C

• workstations B, C, and the E0 interface of the router

• workstations B, C, D, E, F, and the E0 interface of the router

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?

• hub

• router

• switch

• repeater

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

• NIC

• bridge

• hub

• switch

• repeater

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

• switch

• repeater

• router

• bridge

• hub

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

• NIC

• hub

• switch

• router

• repeater

10.

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

• 1

• 2

• 5

• 12

•13

• 15

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 frame is a runt frame.

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

• The transmitting host generated a jam signal during the frame transmission.

• The recalculated checksum for the frame does not match the FCS on the frame.

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?

• bridge

• hub

• router

• transceiver

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

• discard frame

• ignore frame

• send frame to appropriate port

• send frame to all ports except source port

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

• hub

• Layer 2 switch

• router

• bridge

• repeater

15. What is used to prevent Layer 2 switching loops?

• bridging

• segmentation

• Address Resolution Protocol

• Spanning-Tree Protocol
