CCNA 4 - Chapter 3

1 It is important to identify the details of network sections and devices that will be affected or involved in a new design. This information is included in which section of the Network Design
Requirements Document?
#Project Scope


2 Which two pieces of information does the network designer need to determine if the Cisco IOS of a router requires an upgrade? (Choose two.)
#model number of the router
#installed Cisco IOS feature set and version

3 Which
three pieces of information need to be considered when selecting the
proper Cisco IOS version for an upgrade? (Choose three.)
#amount of DRAM
#device make and model
#size of system flash memory


4 What
are two practices a network technician should follow when installing a
new interface card in a router? (Choose two.)
#Handle the interface card by the edges to avoid static discharge.
#Push the interface card into place until the edge connector is seated securely


5 The
new serial interface card for the router arrives and the network
technician reads that it is hotswappable. What does this mean?
#The card can be installed while the router is powered on if the router supports this technology.

6 Refer
to the exhibit. A network administrator issues the command shown to
gain knowledge about a poorly documented network. Which two pieces
of information can the network administrator discover from the
command output? (Choose two.)
#One connected device has router capability.
#Five Cisco devices with CDP enabled are directly connected to device C3750-24_MDF

7 Refer to the exhibit. Which of the three Cisco IOS images shown will load into RAM?
#The router selects an image depending on the boot system command in the configuration.

8 An
administrator wants to download a new Cisco IOS software version to the
local router. Which command performs this task?
#copy tftp flash

9 Refer
to the exhibit. The top of the output shows the Cisco Feature Navigator
regarding a Cisco IOS image that the administrator wants to
install on a router. Below it is the output from the show version
command for that router. Which statement is true regarding the capacity
of the router to
run this Cisco IOS image?
#There is not enough DRAM and flash.

10 Which two items are objectives of a WLAN design site survey? (Choose two.)
#identify coverage areas
#determine primary AP locations


11 Refer
to the exhibit. Which two actions improve the weaknesses of the
topology shown, assuming that each access layer segment is in its
own subnet? (Choose two.)
#Implement redundant links to each server by adding additional NICs.
#Implement a backup firewall with a link to a secondary ISP and implement a redundant link to the DMZ.

12 A
company is beginning to analyze their new Cisco IOS upgrade
requirements. What is one of the router components that a network
administrator must consider when selecting a new Cisco IOS version?
#interfaces and modules to be supported

13 An
employee at a company notices that the wireless signal strength
indicator on his laptop fluctuates from good to low. The network
administrator decides to do a site survey of that area.
Which three factors need to be included in the survey? (Choose three.)
#number of users in the area
#location of the AP

#location of walls and filing cabinets in the office

14 The
new network design for AnyCompany must include support of voice and
video traffic. Before upgrading, the network designer checks
whether the existing devices can support the new
requirements. Which three items does the designer need to check? (Choose three.)
#size of DRAM and flash on each device
#routers that will support HWICs and VWICs

#modules supported on the loaded Cisco IOS

15 A
new Cisco IOS version has been copied into flash from a TFTP server.
When a reload is issued to upgrade the Cisco IOS, the router
freezes part of the way through the loading process. What
could be the problem?
#There is enough flash but not enough RAM in the router.

16 Refer
to the exhibit. A network designer has no documentation and is
attempting to create a logical diagram of the network using the
output from show commands. What can be determined
from the output shown?
#The designer cannot telnet to the attached switch.

17 A
production router is reloaded and finishes with a Router> prompt.
What three facts can be determined? (Choose three.)
#POST occurred normally.
#A full version of the Cisco IOS was located and loaded.
#A configuration file was not located in NVRAM or from a TFTP server.


18 During
a site survey, the network designer noticed that people were accessing
the company wireless network from the parking lot. What should be
done to stop the wireless signal from
radiating out into the parking lot?
#change the type of antenna attached to the AP

19 A
network design project includes a review of the existing network. What
is the purpose of this phase of the project?
#To determine what existing network devices require upgrades to meet the new

20 Refer
to the exhibit. Based upon the Cisco IOS file naming convention, what
is represented by the value ipvoicek9 listed in the IOS filename?
#feature set

21 Refer to the exhibit. What two items can be determined from the output? (Choose two.)
#R2 is a Cisco 2600 device.
#The version of the IOS is 12.3.

22 During
a wireless site survey, a consultant is determining the hours of
peak usage and the estimated number of users in each location. The
consultant is currently in what step of the site survey process?
#the identification of coverage areas

23 Refer
to the exhibit. The network administrator is attempting to install a
new version of the IOS on R2. Based on the exhibited output, what
are two possible reasons that the transfer failed?(Choose two.)
#Connectivity between R2 and the TFTP server was not verified.
#The administrator did not verify that the TFTP server is running.

24 In
which section of the Network Design Requirements document would a
network consulting team detail names and IP addresses of important
networking components and servers, provide network diagrams and
topologies, and define strengths and weaknesses of the network?
#state of the network
