Q1. CORRECT TEXT - (Topic 7)

Central Florida Widgets recently installed a new router in their office. Complete the network installation by performing the initial router configurations and configuring R1PV2 routing using the router command line interface (CLI) on the RC.

Configure the router per the following requirements: Name of the router is R2

Enable. secret password is cisco

The password to access user EXEC mode using the console is cisco2 The password to allow telnet access to the router is cisco3

IPV4 addresses must be configured as follows:

Ethernet network 209.165.201.0/27 - router has fourth assignable host address in subnet Serial network is 192.0.2.176/28 - router has last assignable host address in the subnet. Interfaces should be enabled.

Router protocol is RIPV2

Attention:

In practical examinations, please note the following, the actual information will prevail.

1. Name or the router is xxx

2. Enable. secret password is xxx

3. Password In access user EXEC mode using the console is xxx

4. The password to allow telnet access to the router is xxx

5. IP information

Answer:

Router>enable Router#config terminal Router(config)#hostname R2 R2(config)#enable secret Cisco 1 R2(config)#line console 0

R2(config-line)#password Cisco 2 R2(config-line)#exit R2(config)#line vty 0 4

R2(config-if)#ip address 209.165.201.4 255.255.255.224 R2(config)#interface s0/0/0

R2(config-if)#ip address 192.0.2.190 255.255.255.240 R2(config-if)#no shutdown

R2(config-if)#exit R2(config)#router rip R2(config-router)#version 2

R2(config-router)#network 209.165.201.0

R2(config-router)#network 192.0.2.176

R2(config-router)#end R2#copy run start

Q2. - (Topic 3)

Refer to the graphic.

A static route to the 10.5.6.0/24 network is to be configured on the HFD router. Which commands will accomplish this? (Choose two.)

A. HFD(config)# ip route 10.5.6.0 0.0.0.255 fa0/0

B. HFD(config)# ip route 10.5.6.0 0.0.0.255 10.5.4.6

C. HFD(config)# ip route 10.5.6.0 255.255.255.0 fa0/0

D. HFD(config)# ip route 10.5.6.0 255.255.255.0 10.5.4.6

E. HFD(config)# ip route 10.5.4.6 0.0.0.255 10.5.6.0

F. HFD(config)# ip route 10.5.4.6 255.255.255.0 10.5.6.0

Answer: C,D

Explanation:

The simple syntax of static route:

ip route destination-network-address subnet-mask {next-hop-IP-address | exit-interface}

+ destination-network-address: destination network address of the remote network

+ subnet mask: subnet mask of the destination network

+ next-hop-IP-address: the IP address of the receiving interface on the next-hop router

+ exit-interface: the local interface of this router where the packets will go out In the statement “ip route 10.5.6.0 255.255.255.0 fa0/0:

+ 10.5.6.0 255.255.255.0: the destination network

+fa0/0: the exit-interface

Q3. - (Topic 5)

What will happen if a private IP address is assigned to a public interface connected to an ISP?

A. Addresses in a private range will not be routed on the Internet backbone.

B. Only the ISP router will have the capability to access the public network.

C. The NAT process will be used to translate this address to a valid IP address.

D. A conflict of IP addresses happens, because other public routers can use the same range.

Answer: A

Explanation:

Private RFC 1918 IP addresses are meant to be used by organizations locally within their own network only, and cannot be used globally for Internet use.

Q4. - (Topic 8)

Which statement about switch access ports is true?

A. They drop packets with 802.1Q tags.

B. A VLAN must be assigned to an access port before it is created.

C. They can receive traffic from more than one VLAN with no voice support

D. By default, they carry traffic for VLAN 10.

Answer: A

Explanation:

"If an access port receives a packet with an 802.1Q tag in the header other than the access VLAN value, that port drops the packet without learning its MAC source address."

Q5. - (Topic 3)

Refer to the exhibit.

What commands must be configured on the 2950 switch and the router to allow communication between host 1 and host 2? (Choose two.)

A. Router(config)# interface fastethernet 0/0 Router(config-if)# ip address 192.168.1.1 255.255.255.0 Router(config-if)# no shut down

B. Router(config)# interface fastethernet 0/0 Router(config-if)# no shut down Router(config)# interface fastethernet 0/0.1 Router(config-subif)# encapsulation dot1q 10

Router(config-subif)# ip address 192.168.10.1 255.255.255.0 Router(config)# interface fastethernet 0/0.2

Router(config-subif)# encapsulation dot1q 20

Router(config-subif)# ip address 192.168.20.1 255.255.255.0

C. Router(config)# router eigrp 100 Router(config-router)# network 192.168.10.0

Router(config-router)# network 192.168.20.0

D. Switch1(config)# vlan database Switch1(config-vlan)# vtp domain XYZ

Switch1(config-vlan)# vtp server

E. Switch1(config)# interface fastethernet 0/1 Switch1(config-if)# switchport mode trunk

F. Switch1(config)# interface vlan 1 Switch1(config-if)# ip default-gateway 192.168.1.1

Answer: B,E

Explanation:

The router will need to use subinterfaces, where each subinterface is assigned a VLAN and IP address for each VLAN. On the switch, the connection to the router need to be configured as a trunk using the switchport mode trunk command and it will need a default gateway for VLAN 1.

Q6. - (Topic 8)

Which routing protocol has the smallest default administrative distance?

A. IBGP

B. OSPF

C. IS-IS

D. EIGRP

Q7. DRAG DROP - (Topic 4)

Drag the Frame Relay acronym on the left to match its definition on the right. (Not all acronyms are used.)

Answer:

Q8. - (Topic 8)

On which type of port can switches interconnect for multi-VLAN communication?

A. interface port

B. access port

C. switch port

D. trunk port

Answer: D

Q9. - (Topic 8)

Refer to the exhibit. Which two statements are true about the loopback address that is configured on RouterB? (Choose two.)

A. It ensures that data will be forwarded by RouterB.

B. It provides stability for the OSPF process on RouterB.

C. It specifies that the router ID for RouterB should be 10.0.0.1.

D. It decreases the metric for routes that are advertised from RouterB.

E. It indicates that RouterB should be elected the DR for the LAN.

Answer: B,C

Explanation:

A loopback interface never comes down even if the link is broken so it provides stability for the OSPF process (for example we use that loopback interface as the router-id) -

The router-ID is chosen in the order below:

+ The highest IP address assigned to a loopback (logical) interface.+ If a loopback interface is not defined, the highest IP address of all active router’s physical interfaces will be chosen.

-> The loopback interface will be chosen as the router ID of RouterB –

Q10. - (Topic 3)

Refer to the exhibit.

The network administrator must establish a route by which London workstations can forward traffic to the Manchester workstations. What is the simplest way to accomplish this?

A. Configure a dynamic routing protocol on London to advertise all routes to Manchester.

B. Configure a dynamic routing protocol on London to advertise summarized routes to Manchester.

C. Configure a dynamic routing protocol on Manchester to advertise a default route to the London router.

D. Configure a static default route on London with a next hop of 10.1.1.1.

E. Configure a static route on London to direct all traffic destined for 172.16.0.0/22 to 10.1.1.2.

F. Configure Manchester to advertise a static default route to London.

Answer: E

Explanation:

This static route will allow for communication to the Manchester workstations and it is better to use this more specific route than a default route as traffic destined to the Internet will then not go out the London Internet connection.
