New Cisco 100-105 Exam Dumps Collection (Question 15 - Question 24)

New Questions 15

Refer to the exhibit.

Why are two OSPF designated routers identified on Core-Router?

A. Core-Router is connected to more than one multi-access network.

B. The router at is a secondary DR in case the primary fails.

C. Two router IDs have the same OSPF priority and are therefore tied for DR election

D. The DR election is still underway and there are two contenders for the role.

Answer: A


OSPF elects one DR per multi-access network. In the exhibit there are two DR so there must have more than one multi-access network.

New Questions 16

Which two statements describe the IP address (Choose two.)

A. The subnet address is

B. The lowest host address in the subnet is

C. The last valid host address in the subnet is

D. The broadcast address of the subnet is

E. The network is not subnetted.

Answer: B,D


The mask (/23) used with a Class A address means that there are 15 subnet bits and 9 host bits. The block size in the third octet is 2 (256 - 254). So this makes the subnets in 0, 2, 4, 6, etc., all the way to 254. The host is in the 2.0 subnet. The next subnet is 4.0, so the broadcast address for the 2.0 subnet is 3.255. The valid host addresses are 2.1 through 3.254

New Questions 17

Given an IP address of, what is the subnet address?






Answer: C


248 mask uses 5 bits (1111 1000)

42 IP in binary is (0010 1010)

The base subnet therefore is the lowest binary value that can be written without changing the output of an AND operation of the subnet mask and IP...

1111 1000 AND

0010 1010 equals

0010 1000 - which is .40

/24 is standard class C mask.

Adding the 5 bits from the .248 mask gives /29

New Questions 18

What command sequence will configure a router to run OSPF and add network /24 to area 0?

A. router ospf area 0

network area 0

B. router ospf


C. router ospf 1

network area 0

D. router ospf area 0

network area 0

E. router ospf

network area 0

F. router ospf 1


Answer: C



1.enable 2.configureterminal 3.router ospfprocess-id

4.networkip-addresswildcard-maskareaarea-id 5.end


Command or Action Purpose

Step 1 enable


Device> enable

Enables privileged EXEC mode.

Step 2

Enter your password if prompted.

configure terminal


Device# configure terminal Enters global configuration mode.

Step 3

router ospf process-id


Device(config)# router ospf 109

Enables OSPF routing and enters router configuration mode.

Step 4

network ip-address wildcard-mask area area-id


Device(config-router)# network area 0

Defines an interface on which OSPF runs and defines the area ID for that interface.

Step 5 end


Device(config-router)# end

Exits router configuration mode and returns to privileged EXEC mode.

New Questions 19

Refer to the exhibit.

Which two statements are correct? (Choose two.)

A. This is a default route.

B. Adding the subnet mask is optional for the ip route command.

C. This will allow any host on the network to reach all known destinations beyond RouterA.

D. This command is incorrect, it needs to specify the interface, such as s0/0/0 rather than an IP address.

E. The same command needs to be entered on RouterA so that hosts on the network can reach network

Answer: A,C


This is obviously the default route which is set between the routers and since it is entered in such a manner that it ensures connectivity between the stub network and any host lying beyond RouterA.

New Questions 20

Refer to the exhibit.

Host A can communicate with Host B but not with Hosts C or D. How can the network administrator solve this problem?

A. Configure Hosts C and D with IP addresses in the network.

B. Install a router and configure a route to route between VLANs 2 and 3.

C. Install a second switch and put Hosts C and D on that switch while Hosts A and B remain on the original switch.

D. Enable the VLAN trunking protocol on the switch.

Answer: B


Two VLANs require a router in between otherwise they cannot communicate. Different VLANs and different IP subnets need a router to route between them.

New Questions 21

Refer to the exhibit.

If host A sends an IP packet to host B, what will the source physical address be in the frame when it reaches host B?



C. A1:A1:A1:A1:A1:A1

D. B2:B2:B2:B2:B2:B2

E. C3:C3:C3:C3:C3:C3

F. D4:D4:D4:D4:D4:D4

Answer: E


When packets transfer from one host to another across a routed segment, the source IP address always remains the same source IP address, and the source physical (MAC) address will be the existing routeru2019s interface address. Similarly, the destination IP address always remains the same and the destination physical (MAC) address is the destination routeru2019s interface address.

New Questions 22

Refer to the output of the corporate router routing table shown in the graphic.

The corporate router receives an IP packet with a source IP address of and a destination address of

What will the router do with this packet?

A. It will encapsulate the packet as Frame Relay and forward it out interface Serial 0/0.117.

B. It will discard the packet and send an ICMP Destination Unreachable message out interface FastEthernet 0/0.

C. It will forward the packet out interface Serial 0/1 and send an ICMP Echo Reply message out interface serial 0/0.102.

D. It will change the IP packet to an ARP frame and forward it out FastEthernet 0/0.

Answer: B


Since the destination network is not in the routing table, and no default gateway has been configured, the router will discard the packet and send an ICMP Destination Unreachable message out interface FastEthernet 0/0. It knows to send it out Fa 0/0 because the routing table for the source IP address of shows it was learned from the Fa 0/0 interface.

New Questions 23

Which three statements are correct about RIP version 2? (Choose three)

A. It uses broadcast for its routing updates.

B. It supports authentication.

C. It is a classless routing protocol.

D. It has a lower default administrative distance then RIP version 1.

E. It has the same maximum hop count as RIP version 1.

F. It does not send the subnet mask any updates.

Answer: B,C,E


A and E are correct according to the theory of RIP.

RIP version 1 updates are broadcasts, and RIP version 2 updates are multicast to -> B is not correct.

RIP v1 is a classful routing protocol but RIP v2 is a classless routing protocol -> C is correct.

RIPv1 and RIPv2 have the same default administrative distance of 120 -> D is not correct. RIPv2 is a classless routing protocol so it does send the subnet mask in updates -> F is not correct.

New Questions 24

The network administrator has found the following problem.

The remote networks,, and are accessed through the Central router's serial 0/0 interface. No users are able to access After reviewing the command output shown in the graphic, what is the most likely cause of the problem?

A. no gateway of last resort on Central

B. Central router's not receiving update

C. incorrect static route for

D. not located in Central's routing table

Answer: C


If we use to route to, then the packet will route back. To clear this error we have to use #no ip route

command in configuration mode.
