QUESTION 38 Note: The following 3 questions relate to the scenario below:
Contoso is manufacturer and importer of fasteners, including nuts and bolts. The main
campus is composed ofthree buildings that are less than 200 meters apart. All campus
wiring is Category 5e copper. Network accessand distribution devices are currently 100
Mbps hubs, and the core is a 100 Mbps Layer-2 switch. Developmentof the network has
taken place over the past eight years in a series of steps that involved minimal planning,
withthe exception of the WAN links, which have been recentlyredesigned. The current
network is characterized by slow response and frequent outages. The engineering
department uses a database server located in the engineering building. This server
processes heavy local trafficthat keeps the local network at 70% of bandwidth. Accounting
uses commercial package for general ledger,accounts payable, and accounts receivable;
these packages are located on a server in the administrationbuilding. This server
processes heavy local traffic and light traffic from other buildings. All other servers
arelocated in the information-processing center. All employee use e-mail located on one
server in the information-processing center. There is a web server that is available for
public use and an internal web server that is available to employees for company news
items and for human resource applications, such as an internal jobs-available database.
The external web server is in a new Corporate Internet module.The internal network traffic
is expected to grow at 10% per year for the next five years. The IT manager of Contoso has
asked you to design an up-to-date, high-performance, scalable, secure, manageable, and
reliable campus network to meet the strategic goals of Contoso. Finances are limited, so
the design needs to meet requirements but with minimum cost.

QUESTION 25 Your client has recently upgraded the users in a Token Ring network to PC
running 3270 emulation software. What would you recommend to provide access to an
SNA mainframe in New York across a serial link?
A. RSRB
B. APPN
C. SDLLC
D. STUN
Answer: D
Explanation: The correct answer is STUN as per the Cisco Internet work Design version 3.0
courseware, P 2224. "SDLC tunneling (STUN) has fewer encapsulation options than RSRB: Serial direct between serial ports on the router ... ". The question is here, is this connection in
New York local or not? Since the question has the work "serial" in it, the correct answer should be
STUN, since no-where does is the word "serial" used when
discussing RSRB. If the question say WAN or Frame relay, the answer would be RSRB, but
because they actually say Serial it must be STUN.
QUESTION 26 You have a PRI and 10 users needing dial-in access. The appropriate

A. Per-user access lists at the access server.
B. A server using TACACS + or RADIUS.

QUESTION 28 A router using EIGRP will have a routing table that will contain routes that
______.
A. Are its own and all routers in the segment.
B. Are its own and all adjacent routers.
C. Are its own.
D. Are its own and its neighbors.
Answer: D
Explanation: The correct answer is "Are its own and its neighbors" as per the Cisco Internet work
Design version 3.0 courseware, P 10-23: "In addition to the local routing table, Enhanced IGRP
keeps the active routing table of each adjacent router, which gives the Enhanced IGRP router a
fast way to predict how routing will change when a network link changes state"
QUESTION 29 A broadcast domain:
A. Is all devices contending for the same bandwidth.
B. Does not usually cross routers.
C. Is also called a collision domain in Ethernet terminology.
D. Forwards Domain Name System lookups.
Answer: B
QUESTION 30 Which of the following is not a rule associated with the hierarchical design
model?
A. Use a consistent number of layers throughout the internet work.
B. Use consistent bandwidth links within each layer of the model.
C. Design the core for maximum availability.
D. Implement policy and security at the access layer.
Answer: D

QUESTION 31 Connecting two Novell NetWare Ethernet networks that use different
encapsulation ______.
A. Can be done by configuring sub interfaces on a Cisco router.
B. Can be done by using Enhanced IGRP instead of IPX RIP.
C. Cannot be done.
D. Has no effect on network performance.
Answer: A
Explanation: Per the Cisco Internet work Design version 3.0 courseware, P 12-7: "Sub interfaces
can be. configured on the router to support several IPX networks on the same LAN. Hosts on
different networks do not communicate directly and can use different encapsulations"
