Q82. - (Topic 4) 

The ip helper-address command does what? 

A. assigns an IP address to a host 

B. resolves an IP address from a DNS server 

C. relays a DHCP request across networks 

D. resolves an IP address overlapping issue 

Answer: C 

Explanation: 

http://cisconet.com/tcpip/dhcp/107-how-to-use-ip-helper-address-to-connect-remote-dhcp-

server.html 

When the DHCP client sends the DHCP request packet, it doesn’t have an IP address. So it uses the all-zeroes address, 0.0.0.0, as the IP source address. And it doesn’t know how to reach the DHCP server, so it uses a general broadcast address, 255.255.255.255, for the destination. So the router must replace the source address with its own IP address, for the interface that received the request. And it replaces the destination address with the address specified in the ip helper-address command. The client device’s MAC address is included in the payload of the original DHCP request packet, so the router doesn’t need to do anything to ensure that the server receives this information. The router then relays the DHCP request to the DHCP server. 


Q83. - (Topic 7) 

Refer to the exhibit. 

Which statement describes the effect of this configuration? 

A. The VLAN 10 VTP configuration is displayed. 

B. VLAN 10 spanning-tree output is displayed. 

C. The VLAN 10 configuration is saved when the router exits VLAN configuration mode. 

D. VLAN 10 is added to the VLAN database. 

Answer: D 


Q84. - (Topic 3) 

What is the network address for the host with IP address 192.168.23.61/28? 

A. 192.168.23.0 

B. 192.168.23.32 

C. 192.168.23.48 

D. 192.168.23.56 

E. 192.168.23.60 

Answer: C 

Explanation: 

Convert bit-length prefix to quad-dotted decimal representation, then from it find the number of bits used for subnetting you can find previously calculated number of subnets by separating subnets each having value of last bit used for subnet masking Find that your IP address is in which subnet, that subnet's first address is network address and last address is broadcast address. Based on above steps the answer is option C 


Q85. - (Topic 3) 

Refer to the exhibit. 

If CDP is enabled on all devices and interfaces, which devices will appear in the output of a show cdp neighbors command issued from R2? 

A. R2 and R3 

B. R1 and R3 

C. R3 and S2 

D. R1, S1, S2, and R3 

E. R1, S1, S2, R3, and S3 

Answer: C 

Explanation: 

A Cisco device enabled with CDP sends out periodic interface updates to a multicast address in order to make itself known to neighbors. Since it is a layer two protocol, these packets are not routed. So the devices detected would be immediate connected neighbors.

Q86. - (Topic 3) 

Refer to the exhibit. 

Which command would you use to configure a static route on Router1 to network 192.168.202.0/24 with a nondefault administrative distance? 

A. router1(config)#ip route 1 192.168.201.1 255.255.255.0 192.168.201.2 

B. router1(config)#ip route 192.168.202.0 255.255.255.0 192.168.201.2 1 

C. router1(config)#ip route 5 192.168.202.0 255.255.255.0 192.168.201.2 

D. router1(config)#ip route 192.168.202.0 255.255.255.0 192.168.201.2 5 

Answer: D 

Explanation: 

The default AD for a static route is 1. To change this, configure a different value to be used as the AD at the very end of the “ip route” statement. 


Q87. - (Topic 5) 

Select two options which are security Issues which need to be modified before RouterA is used? (Choose two.) 

A. unencrypted weak password is configured to protect privilege mode 

B. inappropriate wording in banner message 

C. the virtual terminal lines have a weak password configured 

D. virtual terminal lines have a password, but it will not be used 

E. configuration supports un-secure web server access 

Answer: B,D 


Q88. - (Topic 1) 

Refer to the exhibit. 

SwitchA receives the frame with the addressing shown in the exhibit. According to the command output also shown in the exhibit, how will SwitchA handle this frame? 

A. It will drop the frame. 

B. It will forward the frame out port Fa0/6 only. 

C. It will forward the frame out port Fa0/3 only. 

D. It will flood the frame out all ports. 

E. It will flood the frame out all ports except Fa0/3. 

Answer: E 

Explanation: 

When frame receives the frame, it checks the source address on MAC table if MAC address found in MAC table it tries to forward if not in MAC table adds the Address on MAC table. After checking the source address, it checks the destination address on MAC table, if MAC address found on MAC table it forwards to proper ports otherwise floods on all ports except the source port. 


Q89. - (Topic 3) 

Which address are OSPF hello packets addressed to on point-to-point networks? 

A. 224.0.0.5 

B. 172.16.0.1 

C. 192.168.0.5 

D. 223.0.0.1 

E. 254.255.255.255 

Answer: A 

Explanation: 

Why does the show ip ospf neighbor Command Reveal Neighbors in the Init State? http://www.cisco.com/en/US/tech/tk365/technologies_tech_note09186a0080093f11.shtml OSPF hello packets have a destination address of 224.0.0.5 (the all ospf routers multicast 

address). 


Q90. - (Topic 3) 

Refer to the exhibit. 

A network associate has configured OSPF with the command: 

City(config-router)# network 192.168.12.64 0.0.0.63 area 0 

After completing the configuration, the associate discovers that not all the interfaces are participating in OSPF. Which three of the interfaces shown in the exhibit will participate in OSPF according to this configuration statement? (Choose three.) 

A. FastEthernet0 /0 

B. FastEthernet0 /1 

C. Serial0/0 

D. Serial0/1.102 

E. Serial0/1.103 

F. Serial0/1.104 

Answer: B,C,D 

Explanation: 

The “network 192.168.12.64 0.0.0.63 equals to network 192.168.12.64/26. This network has: 

+

 Increment: 64 (/26= 1111 1111.1111 1111.1111 1111.1100 0000) 

+

 Network address: 192.168.12.64 

+

 Broadcast address: 192.168.12.127 

Therefore all interface in the range of this network will join OSPF.
