The stuff had drag and drops, exhibits and all that
is required for the exam.

all of the packets on the VLAN. Which technique would
the hacker use?

QUESTION NO: 5
A customer is trying to decide what type of VPN to implement.
They are trying to decide between an IPSec VPN and a
Secure Socket Layer (SSL) VPN. They need to support
remote access and branch office VPNs. Which option should
they choose and why?
A. SSL VPN, because it does not require client software
B. SSL VPN, because it supports the use of a web browser
to establish the VPN.
C. IPSec VPN, because it supports branch office and
remote access users.
D. IPSec VPN, because it is supported by all router
and firewall implementations.
QUESTION NO: 6

or hardware cannot be used on the network. The Information
Technology (IT) department has requested that they be
excluded from this policy. Which justification best
explains why IT needs packet capture software?

the same collision domain
D. to bill departments for network use
QUESTION NO: 7

QUESTION NO: 8
A customer is concerned about implementing Internet
Group Management Protocol (IGMP) v2 on their network.
They wonder what would happen if a multicast application
on their PC either died or was shut down before sending
the leave group message. What should you tell the customer
to reassure them?
A. The PC will issue a leave message automatically when
it receives multicast traffic for a group to which it
is not subscribed.
B. The switch will send the multicast stream to the
port attached to the PC until the multicast stream ends
or the port is inactive.
C. The PC will be removed from the IGMP group when it
fails to respond to a specified number of membership
D. The PC will be removed from the IGMP group when it
fails to respond to host membership reports.
QUESTION NO: 9
A large retail store has decided to use a wireless network
to attach cash registers and computers and computers
to the network, so that they can rearrange the floor
layout without having to pull network cable every time
they rearrange displays. The issue is that when they
first tried to implement IEE 802.11b last year, there
was too much interference from other WLANs and cordless
telephones, and the computers received very poor signal
strength.Which change would most help fix this problem?
A. Use 802.11g to increase the number of channels available.
B. Use 802.11a on the 5GHz range with more channels.
C. Use 802.11b on a non-standard channel to keep from
conflicting with the other WLANs.
D. Use 802.11b on thealtemate 5GHz range with more channels.
QUESTION NO: 10
A customer would like to specify the source IP addresses
for multicast feeds that will be accepted on the host
systems. They would also like the ability to specify
that hosts not receive data from particular source IP
addresses. Which protocol allows the host to filter
multicast traffic, based upon source IP address?
A. Internet Group Management Protocol (IGMP) v2
B. Protocol Independent Multicast - Sparse Mode (PIM-SM)
C. Internet Group Management Protocol (IGMP) v3
D. Distance Vector Multicast Routing Protocol (DVMRP)
QUESTION NO: 11
Line-of-sight is one of the boundaries of Radio Frequency
(RF) waves. They are also affected by obstacles that
can cause the waves to bend, bounce, or become distorted.
Which type of electromagnetic wave is a radio wave?
A. direct wave
B. ground wave
C. space wave
D. fluid wave
QUESTION NO: 12
An engineer downloaded confidential email while working
from a hotspot. The hotspot requires that the user login,
but does not have data encryption. The email program
uses POP3 to transfer email and does not use encryption.
Another patron at the hotspot was running packet capture
software on the WLAN and received all of the engineer
email in plain text. Which security measure, if taken
by the engineer, would be ineffective?
A. Use a VNP to connect into corporate and check email,
the VPN would encrypt the traffic.
B. Connect only to access points that use an encryption
protocol to encrypt data.
C. Select only an email program that encrypts the messages
using a secure protocol such as SSL.
D. Select an email program that uses HTTP to transfer
QUESTION NO: 13
A customer has enabled Single Host Single Authentication
Extensible Authentication Protocol over LAN (EAPoL)
on ports on their Ethernet switch. Not all PCs have
the ability to authenticate against the RADIUS server.
They would like to allow these users to access limited
network resources, and they do not want to use MAC authentication
against the non-EAP customers. Which EAPoL feature should
they use to allow non-EAP-enabled customers to send
data on an EAP-enabled port when there are no authorized
A. Multi-host single authentication (MHSA)
B. Guest VLAN
C. Multi-host multiple authentication (MHMA)
D. Non-EAP hosts (NEAP)
