Which of the following devices acts as a gateway between clients and servers?
A. WINS server
B. Proxy server
C. Content filter
D. DNS server
Correct Answer: B

A network administrator suspects a broadcast storm is causing performance issues on the network. Which of the
following would be used to verify this situation?
A. Environmental monitor
B. Multimeter
C. Toner probe
D. Protocol analyzer
Correct Answer: D
A “Protocol analyzer” is a tool (hardware or software) used to capture and analyze signals and data traffic over a
communication channel.

Which of the following is the control when observing network bandwidth patterns over time?
A. Network log
B. Baseline
C. Flow data
D. Interface statistics
Correct Answer: B
To successfully baseline a network it is important to consider two functions; performance at protocol level and
performance at application level. There are many significant metrics to consider at the protocol level, but only a few
which are critical. The most important is bandwidth utilization compared with bandwidth availability. The most likely
cause of poor network performance is insufficient bandwidth. Trending bandwidth utilization allows you to recognize
problem areas, provide enough bandwidth to reach performance objectives, and predict future capacity requirements.
Changes in bandwidth utilization patterns also provide a clear indication of network usage alterations, such as a change
in end-user behavior, or the unauthorized addition of an application.

Which of the following wireless parameters may need to be modified when a new cordless telephone is installed?
A. Encryption type
C. IP address
D. Channel
Correct Answer: D

A technician has low signal strength connecting two wireless bridges. Which of the following could be the problem?
A. Low PoE wattage
B. Opposing antenna polarizations
C. Short distance between antennas
D. WPA 2 encryption
Correct Answer: B
The polarization of an antenna is the orientation of the electric field (E-plane) of the radio wave with respect to the
Earth\\’s surface and is determined by the physical structure of the antenna and by its orientation. It has nothing in
common with antenna directionality terms: “horizontal”, “vertical”, and “circular”. Thus, a simple straight wire antenna will
have one polarization when mounted vertically, and a different polarization when mounted horizontally.

Which of the following would a technician do to monitor remote traffic through an access point?
A. Enable an SNMP agent
B. Enable network mapping
C. Set monitoring SSID
D. Select WPA2
Correct Answer: A
Large networks with hundreds or thousands of nodes are difficult to manage without a large staff to monitor every
computer. SNMP, which is widely used in local area networks (LANs), lets you monitor network nodes from a
management host. You can monitor network devices such as servers, workstations, printers, routers, bridges, and hubs,
as well as services such as Dynamic Host Configuration Protocol (DHCP) or Windows Internet Name Service (WINS).

Which of the following would be the BEST solution for an IDS to monitor known attacks?
A. Host-based
B. Signature-based
C. Network-based
D. Behavior-based

Some employees are unable to maintain a wireless network connection. The network\\’s wireless infrastructure is
comprised of three different buildings with the configurations listed below. Wireless network in Building A and C is used
exclusively for internal employees and Building B is used for visitors and requires no additional configuration on their
Which of the following settings would need to be modified to provide the BEST wireless experience for all employees as
they move between buildings?
Building A Building B Building C Channel: 1 Channel: 6 Channel: 11 Encryption: WPA2 Encryption: Open Encryption:
WPA2 SSID. Corp SSID. Guest SSID. Sales
A. Change Channel in Building B to 7
B. Change Encryption in Building B to match A and C
C. Change Channel in Building C to 1
D. Change SSID in Building C to match Building A
Correct Answer: D
The configuration difference between users in building A and C is that they have same encryption however the SSID is
different so the user has to manually authenticate and connect to the network whenever he will move between buildings.
If the SSID\\’s are same then he will not have to authenticate himself again and he will get automatic connectivity.

After a new user moves furniture into a cubicle, the computer does not connect to the network any longer. Which of the
following would be the MOST likely reason? (Select TWO).
A. Bad Ethernet switch port
B. TX/RX reversed
C. Bad connectors

E. Mismatched MTU
Correct Answer: CD
It could be problem with the bad connector because the user just moved furniture to the cubicle and it is quite possible
that the movement of the furniture has created problem by disrupting the cabling and connections. These two are the
important things which can be broken down whenever there is a physical movement.

network resources for an organization. Which of the following would BEST provide this functionality?
B. Single sign on
C. Multifactor authentication
D. Two-factor authentication
Correct Answer: B
Single sign-on (SSO)is a session/user authentication process that permits a user to enter one name and password in
order to access multiple applications. The process authenticates the user for all the applications they have been given
rights to and eliminates further prompts when they switch applications during a particular session.
