affected or
involved in a new design. This information is included in which section of the
Network Design
Requirements Document?
Project Goal

Technical Requirements
Current State of the Network
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.)
amount of NVRAM installed
model number of the router
number of interfaces and installed HWICs
installed Cisco IOS feature set and version
error statistics for each interface
3
Which three pieces of information need to be considered when selecting the proper
Cisco IOS
version for an upgrade? (Choose three.)
processor ID
interface type
amount of DRAM
bootstrap version

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.)
Be sure the interface card faceplate does not touch the chassis rear panel.
Do not tighten the captive screws until the router has been powered on and recognizes
the card.
Store the blank faceplate inside the card slot to be used if the card is removed.
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 cannot be installed while the router is powered on because static discharge
could damage the card.
The card cannot be installed until the router is powered off and completely cooled
down.
The card can be installed while the router is powered on if the router supports this
technology.
The card is a replacement and must be installed in the same slot as the card it is
replacing.
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.)

None of the directly connected network devices have been configured with an IP
address.
Device EDGE_2811 is connected to port Fast Ethernet 0/0 on device C3750-
24_MDF.
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 value of the configuration register.
The router selects the third Cisco IOS image because it is the most recent IOS image.

The router selects an image depending on the boot system command in the
configuration.
The router selects the third Cisco IOS image because it contains the advipservicesk9
image.

router. Which
command performs this task?

copy flash run
copy start tftp
copy flash tftp

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.
There is enough DRAM and flash.
There is enough DRAM but not enough flash.
There is enough flash but not enough DRAM.
10
Which two items are objectives of a WLAN design site survey? (Choose two.)
identify coverage areas
determine primary AP locations
determine what AP equipment should be purchased
determine how many users will access the WLAN
identify the bottleneck of the LAN infrastructure
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 reduntant link from all access layer switches to Admin, Dist, and Server
Farm.
Implement a backup firewall with a link to a secondary ISP and implement a
redundant link to the DMZ.
Implement reduntant links from the existing firewall to all access layer switches.
Implement redundant links from the DMZ to Admin and Dist.
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?
processor type
storage space in NVRAM
interfaces and modules to be supported
compatibility of the bootstrap version with the new Cisco IOS software
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.)
type and model number of the WNIC of the laptop
number of users in the area
location of the AP
list of MAC addresses filtered by the AP
number of simultaneous applications running on the laptop of the employee
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.)
number of routers and switches owned by AnyCompany
routers that will support extra ASICs and WWICs
size of DRAM and flash on each device
routers that will support HWICs and VWICs

system bootstrap version on each router and switch
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.
The new HWIC cards have not been installed yet.
The TFTP server needs to be present during a reload.

There is not enough RAM or flash on this router.
A full version of the Cisco IOS was located and loaded.
A configuration file was not located in NVRAM or from a TFTP server.
The router did not locate the Cisco IOS in flash, so it defaulted to ROM.
18
