Computer Networks Practice Test 7

1. What is route poisoning?

It is information received from a router that can't be sent back to the originating router.RIPv2 supports classless routing

It prevents regular update messages from reinstating a route that has just come up

It describes when a router sets the metric for a downed link to infinity

It sends back the protocol received from a router as a poison pill, which stops the regular updates. The use of variable length subnet masks is permitted

2. In Novell's use of RIP, there are two metrics used to make routing decisions. Select the correct metrics.

Loops & Counts

Counts & Ticks

Hops & Loops

Ticks & Hops

3. Which command displays RIP routing updates?

Show IP route

Debug IP rip

Show protocols

Debug IP route

4. Default administrative distance of a static route is ________

100

5. If you wanted to have 12 subnets with a Class C network ID, which subnet mask would you use?

255.255.255.255

255.255.255.240

255.255.255.248

255.255.255.252

6. Which statement is true regarding classless routing protocol?

RIPv1 is a classless routing protocol

Use of variable length subnet masks is permitted

The use of discontinuous networks is not allowed

IGRP supports classes routing within the same autonomous system

7. What is the subnet id of a host with an IP address 172.16.66.0/21?

172.16.48.0

172.16.0.0

172.16.36.0

172.16.64.0

8. NetWare IPX addressing uses a network number and a node number. Which statement is not true?

The network address is administratively assigned and can be up to 16 hexadecimal digits long

The node address is usually the MAC address

If the MAC address is used as the node address, then IPX eliminates the use of ARP

The node address is always administratively assigned

9. Which routing protocol implements the diffusing update algorithm?

IS-IS

EIGRP

OSPF

IGRP

10. _________ is a collective term for a number of Ethernet Standards that carry traffic at the nominal rate of 1000 Mbit/s against the original Ethernet speed of 10 Mbit/s.

Fast Ethernet

Ethernet

Gigabit Ethernet

Gigabyte Ethernet
