13 During a review of the proposed bill of materials, the ABC Networking Company account manager realizes that the systems engineer included a lower cost, less capable switch model for the access layer connectivity than was specified by the network designer. When questioned, the systems engineer responds that the switches that were recommended 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 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.

Inform the customer that the project budget must be increased.

It allows a greater variety of network devices to be used for VPN connections.

16

Refer to the exhibit. What does the JAX router do with traffic that is destined for a web server with an IP address of 128.107.10.24?

The traffic is sent out Serial 0/0/0.

The router sends the traffic out all interfaces other than the one it came in on.

A request is sent to neighboring routers for paths to the 128.107.0.0 network.

The packets are placed into a queue until a better route is discovered via RIP.

There is a single route to the 172.18.20.0/24 LAN via the DSL connection.

EIGRP installs all three routes to the 172.18.20.0/24 LAN and load balances the traffic.

25

Refer to the exhibit. A network designer is validating an IP addressing scheme with a test network that is configured with RIPv1. However, while the designer can ping between routers RA and RB, communications between network A and network B cannot be established. What should be done to solve the problem?

Change the routing protocol.

Use the S0/0/0 interface on RB to connect to RA.

Configure both routers with the no auto-summary command.

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.

28 What is meant by "tunneling" in the context of migrating from IPv4 to IPv6?

obtaining IPv6 addresses from an IPv4 DHCP server

allowing both protocol stacks to run on the same network device

encapsulating one protocol packet within another protocol

30 A user in a large office calls tech support to complain that the PC no longer connects to the Internet or to any network resources, but seems otherwise normal. The help desk technician asks the caller to talk to nearby users to see if other machines are affected. After a few minutes, the caller reports that several immediate neighbors have the same problem, but those seated further away do not. Assuming that the description is accurate, what should be checked next?

power outlet to the PC that is used by the caller

workgroup switch in the telecommunications room

cable between any network outlet and the telecommunications room

cable between the PC that is used by the caller and the network outlet it connects to

cable between the PC that is used by a neighbor and the network outlet the neighbor PC it connects to
