Networking Chapter 7 Quiz

1. What is a router? A. A piece of hardware that forwards packets based on IP address B. A device that separates your computers from the Internet C. A piece of hardware that distributes a single Internet connection to multiple computers D. A synonym for a firewall

1. A. A router is a piece of hardware that forwards packets based on IP address.

10. The traceroute utility is useful for? A. Configuring routers remotely B. Showing the physical location of the route between you and the destination C. Discovering information about the routers between you and the destination address D. Fixing the computer's local routing table

10. C. The traceroute utility is useful for discovering information about the routers between you and the destination address.

2. Routers must use the same type of connection for all routes, such as Ethernet to Ethernet or ATM to ATM. A. True B. False

2. B. False; a router can interconnect different Layer 2 technologies.

3. What technology allows you to share a single public IP address with many computers? A. Static Address Translation B. Natural Address Translation C. Computed Public Address Translation D. Port Address Translation

3. D. Port Address Translation, commonly known as PAT, enables you to share a single public IP address with many computers.

4. Given the following routing table: where would a packet with the address 64.165.5.34 be sent? A. To the default gateway on interface WAN. B. To the 10.11.12.0/24 network on interface LAN. C. To the 64.165.5.0/24 network on interface WAN. D. Nowhere; the routing table does not have a route for that address.

4. C. It would be sent to the 64.165.5.0/24 network on interface WAN.

5. Distance vector routing protocols such as RIP rely on what metric to determine the best route? A. Hop count. B. Link speed. C. Ping time. D. Routes are chosen at random.

5. A. Distance vector routing protocols use hop count to determine the best route.

6. What are two big advantages to using OSPF over RIP? (Select two.) A. OSPF is a modern protocol that does not have legacy problems. B. OSPF chooses routes based on link speed, not hop count. C. OSPF runs on all routers, big and small. D. OSPF sends only routing table changes, reducing network traffic.

6. B and D. OSPF bases routes on speed and sends only route changes to minimize traffic.

7. What is Area 0 called in OSPF? A. Local Area B. Primary Zone C. Trunk D. Backbone

7. D. Area 0 is called the backbone area.

8. What is the name of the cable that you use to connect to the console port on Cisco routers? A. Router console cable B. Yost cable C. That funny blue Cisco cable D. Null modem cable

8. B. You use Yost cable, which was invented to standardize the serial console interface, to connect to the console port on Cisco routers.

9. When you are first setting up a new router, you should never plug it into an existing network. A. True B. False

9. A. True; never plug a new router into an existing network.
