Answers to Assessment Test

39.  B.  Only the EIGRP route will be placed in the routing table because EIGRP has the low-

est administrative distance (AD), and that is always used before metrics. See Chapter 8 for 

more information.

40.  D.  Switches send information about only one VLAN down a link unless it is configured as 

a trunk link. See Chapter 11 for more information.

41.  B, G.  To enable OSPF, you must first start OSPF using a process ID. The number is irrel-

evant; just choose a number from 1 to 65,535 and you’re good to go. After you start the 

OSPF process, you must configure interfaces on which to activate OSPF using the network 

command with wildcards and specification of an area. Option F is wrong because there 

must be a space after the parameter area and before you list the area number. See Chapter 9 

for more information.

42.  A.  By default, switches break up collision domains on a per-port basis but are one large 

broadcast domain. See Chapter 1 for more information.

43.  B.  At the moment of OSPF process startup, the highest IP address on any active interface 

will be the router ID (RID) of the router. If you have a loopback interface configured  

(logical interface), then that will override the interface IP address and become the RID of 

the router automatically. See Chapter 18 for more information.

44.  C, D.  VLAN Trunking Protocol (VTP) is not right because it has nothing to do with trunk-

ing except that it sends VLAN information across a trunk link. 802.1q and ISL encapsula-

tions are used to configure trunking on a port. See Chapter 11 for more information.

45.  D.  Stub networks have only one connection to an internetwork. Default routes should be 

set on a stub network or network loops may occur; however, there are exceptions to this 

rule. See Chapter 9 for more information.
