Question 1

A routing domain uses a link-state routing protocol. Which of the following would NOT be an advantage of dividing the entire routing domain into areas?

A : Detailed topology information is only shared among routers within the same area, thus reducing the complexity of the SPF calculation.

B : Route tables can be reduced by summarizing the IP prefixes advertised between areas.

C : Less-capable routers can be isolated from having to keep track of IP prefixes that are external to the local routing domain.

D : Fewer routers are required to handle the same amount of traffic, as compared to a single-area domain.

Answer: D

Question 2

You work as the network administrator at ABC.com. The ABC.com network has a domain named ABC.com.

The servers at the ABC.com network run Windows Server 2003 and the workstations, Windows XP

Professional.

ABC.com has recently configured a server named ABC-SR01 to make use of IPSec to connections to it.

What actions must you take to check if there are any IPSec connections to ABC-SR01?

A : You should run the Netsh ipsec dynamic show all.

B : You should run the Net start /show all

C : u should run the wuauclt /detectnow

D : u should run the Nslookup.

Answer: A

Question 3

You are using Network Monitor to analyze IPSec packets that are using ESP. The data packet section is not viewable. What must you do to properly view the data packet section of the frames?

A : t ESP to use the same encryption policy as the Network Monitor machine.

B : able AH policies.

C : tall the ESP filter DLL and update the parser.ini file.

D : nfigure the ESP policy to use null encryption.

Answer: D

Question 4

A routing domain is using a single-area link-state routing protocol. Which of the following is NOT information that a router can share with other routers in the domain using protocol-specific messages?

A : The IP prefixes of subnets directly attached to the router.

B : IP prefixes known by the router because it is running ad additional routing protocol.

C : A copy of the local routing table.

D : The local router ID and the router IDs of neighboring routers.

Answer: C

Question 5

Refer to the exhibit.Routers R1 through R4 are running an IGP in such a way that they have each others system IP addresses in their routing tables. A static route is configured on router R1 so that it can reach subnetwork 10.4.100.0. The network administrator decides to use an indirect static route, as shown in the diagram. However, pinging the server from router R1 fails. What may be the problem in this case?

A : Router R1 drops the echo request because address 10.10.10.3 does not belong to an adjacent router.

B : Router R2 drops the echo request because it does not have subnet 10.4.100.0 in its routing table.

C : Router R3 drops the echo request because it does not have subnet 10.4.100.0 in its routing table.

D : The echo request arrives at the server but there is no path for the echo response to return to router R1.
