Solutions
A user on your network has been moved to another office down
the hall. After the move she calls you complaining that she has
only occasional network access through her wireless connection.
Which of the following is most likely the cause of the problem?
Correct Answers The client system has moved too far away
from the access point.
An all-in-one security appliance is best suited for which type of
implementation? Correct Answers A remote office with no on-
site technician.
As a security precaution, you have implemented IPsec that is
used between any two devices on your network. IPsec provides
encryption for traffic between devices. You would like to
implement a solution that can scan the contents of the encrypted
traffic to prevent any malicious attacks. Which solution should
you implement? Correct Answers Host-based IDS
At what OSI layer does a router operate to forward network
messages? Correct Answers Network
At which layer of the OSI model do hubs operate? Correct
Answers Physical
At which of the following OSI layers does a router operate?
Correct Answers Layer 3
,Due to budget constraints, your client wants to upgrade only the
wireless access points in the network this year. Next year, she
will upgrade the wireless network boards in her users'
workstations. She has also indicated that the system must
continue to function during the transition period. Which 802.11
standard will work best in this situation? Correct Answers
802.11g
Ethernet 100BaseFX networks use what type of cabling?
Correct Answers Fiber optic
If your antivirus software does not detect and remove a virus,
what should you try first? Correct Answers Update your virus
detection software.
In a variation of the brute force attack, an attacker may use a
predefined list (dictionary) of commonly used usernames and
passwords to gain access to existing user accounts. Which
countermeasure best addresses this issue? Correct Answers A
strong password policy
In the OSI model, what is the primary function of the Network
layer? Correct Answers Routes messages between networks
In the OSI model, which of the following functions are
performed at the Application layer? Correct Answers
Integration of network functionality into the host operating
system AND Enabling communication between network clients
and services.
, In the OSI model, which of the following functions are
performed at the Presentation layer? (Select two.) Correct
Answers Specify data format (such as file formats) AND
Encrypt and compress data
Network signaling is a function of which layer of the OSI
model? Correct Answers Physical Layer
Review the output from the show interfaces fa0/1 command on
the switch2 switch in the exhibit. What is wrong with the fa0/1
interface in this example? Correct Answers A duplex mismatch
exists with the device on the other end of the connection.
The configuration document identifies specific configuration
information for a device. It might include information about the
connection to the network. A network diagram might include the
location of the workstation on your site and its connection to the
network. A wiring schematic might include information about
how the device connects to the punchdown blocks or patch
panels. For each of these documents, simply changing the drop
cable does not alter the information that would be in each
document, so no change would be required. Correct Answers
MAC flooding
The Data Link Layer of the OSI model is comprised of two
sublayers. What are they? (Select two.) Correct Answers LLC
and MAC
The router receives a packet addressed to network 10.1.0.0/16.
What will the router do with the packet? Correct Answers
