4

Refer to the exhibit. What can the field engineer conclude about the EIGRP authentication between RouterA

and RouterB?

Authentication will fail because only one key is configured.

Authentication will fail because the key chain names do not match.

Authentication will succeed and EIGRP updates can be exchanged.

Authentication will fail because the key chain names must match the router names.

5

Refer to the exhibit. A networking company designer is reviewing a diagram of a customer network. What are

the two problems that need to be resolved in the topology that is shown? (Choose two.)

The firewall router and ISP connection represent a single point of failure.

If one of the Layer 3 switches fails, the Cisco Call Manager will be unreachable.

A power supply failure of the server block switch will cause the entire IP telephony system to fail.

Using Layer 3 switches to interconnect the server block servers to the IP phones introduces too much delay.

The IP phones need to be redundantly connected to the switches to prevent single points of failure at the

access layer.

to allow connectivity between traditional phone devices and IP-based telephony devices

9 While troubleshooting a Frame Relay link, the network administrator executes the show ip interface brief

command on both sides of the PVC link. All interfaces show a configured IP address and that the line protocol is

ip 10.1.10.1 35 on a router? (Choose two.)

The remote router updates the Frame Relay map table with DLCI 35 to reach the 10.1.10.0 network.

DLCI 35 replaces the MAC address in the ARP table for entry 10.1.10.1.

A Layer 2 address is statically mapped to a Layer 3 address.

Router BRT uses DLCI 35 to forward data to 10.1.10.1.

The WAN links need IP addresses from a different major network.

The WAN link that connects R1 to R2 overlaps with the R3 LAN.

The IP addressing in R1 LAN is incorrect because subnet zero cannot be used with VLSM.

20 A large company plans to add several servers and requires that the servers be reachable directly from the

Internet. Which action will help the company accomplish this goal?

Assign to each server a static internal IP address that is mapped statically to a public IP address.

Place all servers in their own Class C private subnet.

Provide a private address to each server using DHCP.

Assign addresses from a pool of public Class B addresses using DHCP.

21

Refer to the exhibit. A network associate is configuring a new router to provide routing between VLANs. The

associate removes the router from the box and connects the Fa0/0 interface to a trunking port on the switch.

After the configuration is applied to the router, the traffic between VLANs still fails. What is causing this to

occur?

The router needs a routing protocol configured.

The router needs additional Fast Ethernet interfaces installed.

The subinterfaces of the router should have IP addresses applied.

All the subinterfaces of the router should be configured in the same VLAN.

The subinterfaces must be the same value as the VLAN ID that they are routing for.

22 The network infrastructure at the headquarters of an organization consists of Cisco network devices that are

running RIPv1. As part of an upgrade project, a portion of the company backbone will be increased to 10 Gb/s

BGP

EIGRP

OSPF

RIPv2

23 The main office of a NetworkingCompany customer currently connects to three branch offices via three separate

point-to-point T1 circuits. The customer network uses RIPv2 as the routing protocol within both the LAN and

the WAN. The account manager proposes a change to a Frame Relay network because the costs are lower. A

single local loop connection can be installed at the main office with three separate PVCs to connect the branch

offices. How can the main office edge router be configured to enable the customer to continue to use RIP as the

WAN routing protocol?

Enable Inverse ARP on the serial interface in order to learn the routes to the IP addresses of the remote

routers.

To prevent the Frame Relay network from causing a routing loop, disable split horizon on the serial

interface.

Create three separate point-to-point subinterfaces on the serial interface and assign a different subnet IP

address to each one.

Configure the serial interface with a single interface DLCI number and create frame-relay map statements

for each remote site address.

24 A network designer has chosen to specify the use of a dedicated firewall appliance at the perimeter of a large

network. Why would the designer use a dedicated firewall rather than using the Cisco IOS firewall feature set on

the existing router?

Traffic filtering is needed on the internal LAN.

Multiple levels of access to the network are needed.

The DMZ requires packet filtering and port blocking.

Heavy network traffic will be handled best by using a dedicated device.

Ensure that automatic route summarization has been disabled on all routers in the network.

Change the IP address for the Router3 LAN to be 192.168.7.0/24.

It allows user traffic that is destined for the corporate network to travel across the VPN tunnel, while traffic

destined for the Internet travels through the local LAN of the VPN client.

It allows separate tunnels so that high priority traffic, such as voice and video, uses the higher bandwidth

tunnel, while all other user traffic travels on the lower bandwidth tunnel.

50 During a review of the proposed bill of materials, an account manager of the network solution company realizes

that the systems engineer included a switch with lower cost and reduced capabilities for the access layer than

was originally specified by the network designer. When questioned, the systems engineer responds that the

switches specified by the designer cannot be purchased within the budget limitations of the customer. Which

action should the account manager take?

Inform the customer that the project budget must be increased.

Inform the customer that the project cannot be completed given the unreasonable budget constraints.

Communicate any risks that are associated with the equipment substitution and obtain customer approval to

proceed.

Because the customer is probably aware that the budget limitations will require lower cost, less capable

equipment, the account manager should do nothing.
