Question 1:

Which describes the changes made to a packet's IP destination address, as that packet is passed from router to router on it's way to the destination host?

   The destination IP address changes each hop, to be the address of the next router.

   The destination IP address changes anytime a router is sending the packet over a WAN.

   The destination IP address will always be the address of the first router.

   The destination IP address never changes.

 

Question 2:

When sending data to a host on a different network, the source host encapsulates data so that it contains what destination address in the IP header?

   IP address of the router

   MAC address of the router

   MAC address of the destination device

   IP address of the destination host

 

Question 3:

Which protocol is used to dynamically assign IP addresses?

   DHCP

   ARP

   proxy ARP

   IGRP

 

uestion 4:

What are the two proprietary routing protocols developed by Cisco?

   RIP and OSPF

   IGRP and EIGRP

   IPX and SPX

   TCP and IP

 

Question 5:

What is the most common protocol used to transfer routing information between routers located on the same network?

   OSPF

   RIP

   IGRP

   EIGRP

Question 6:

The IP address for a router interface should be part of what?

   the network attached to the interface

   any network attached to the router

   it does not matter

   router interfaces never have IP addresses

 

Question 7:

What is the correct term for when routes are learned automatically?

   automatic routing

   enhanced routing

   dynamic routing

 

Question 8:

Which is an example of a Layer 3 internetworking device that passes data packets between networks?

   router

   hub

   bridge

   switch

 

Question 9:

Which is an example of a routed protocol?

   RIP

   IPX/SPX

   EIGRP

   OSPF

 

Question 10:

Connection-oriented network processes are often referred to as what?

   packet switched

   segment switched

   circuit switched

   network switched

 

Question 11:

Which of the following is an example of an IGP (Interior Gateway Protocol)?

   IPX

   SPX

   UDP

   IGRP

 

Question 12:

Which type of routing protocol is RIP?

   distance vector

   link state

   hybrid

   spanning tree

 

Question 13:

Router ARP tables hold information from which of the following?

   all Ethernet LANs

   all networks connected to them

   all networks in the Internet

   MAC addresses only

 

Question 14:

In a connectionless system, which of the following is correct?

   The destination is not contacted before a packet is sent.

   The destination is contacted before a packet is sent.

   A connectionless connection is established with the recipient before a packet is sent.

   A non-connection is established between the sender and recipient before a packet is sent.

 

Question 15:

What do bridges and switches use to make data forwarding decisions?

   logical addresses

   physical addresses

   network addresses

   IP addresses

 

Question 16:

Which type of routing allows routers to adjust to changing network conditions?

   static

   dynamic

   automatic

   stub

 

Question 17:

What do routers use to exchange routing tables and share route information?

   routed protocols

   transport protocols

   routing protocols

   UDP protocols

 

Question 18:

Which protocol can find the MAC address of a computer given its IP address?

   RARP

   DHCP

   ARP

   Proxy RARP

 

Question 19:

When configuring a host computer, which of the following describes the router interface that connects to the same network segment?

   default interface

   default gateway

   default port

   default subnet

 

Question 20:

Which of the following contains a unique network number that is used in routing?

   MAC address

   physical address

   IP address

   NIC card

 

Question 21:

What happens if a data packet reaches a router that is destined for a network with which that router is not directly connected?

   The router forwards the packet to all other routers.

   The router returns the packet to the source device with no explanation.

   The router forwards the packet to another router that most likely contains information about the destination.

   The router returns the packet to the source device with the explanation that the destination was unreachable.

 

Question 22:

What is described when a router acts as a default gateway, allowing a device on one subnet to find the MAC address of a host on another subnet?

   proxy ARP

   proxy RARP

   RARP

   subnetting

 

Question 23:

In a connection-oriented system, what happens before any user data is transferred?

   a connection is established with the recipient's local router

   a connection is established between the sender and receiver

   a connection is established with the sender's local router

   the destination is not contacted before any actual data is sent

 

Question 24:

Which is a network layer protocol that can be routed?

   IP

   ISP

   NetBEUI

   ARP

 

Question 25:

Why is a static route the preferred method for reaching stub networks?

   static routing requires less overhead

   static routing requires more overhead on the network

   this allows routers to adjust to changes in the network

   the routes are learned automatically

 

Question 26:
