QUESTION 45
Which of the following best practices makes a wireless network more difficult to find?
A. Implement MAC filtering
B. UseWPA2-PSK
C. Disable SSID broadcast
D. Power down unused WAPs

Correct Answer: C Explanation
Explanation/Reference:
Network administrators may choose to disable SSID broadcast to hide their network from unauthorized personnel. However, the SSID is still needed to direct
packets to and from the base station, so it’s a discoverable value using a wireless packet sniffer. Thus, the SSID should be disabled if the network isn’t for public
use.
Incorrect Answers:

A: A MAC filter is a list of authorized wireless client interface MAC addresses that is used by a WAP to block access to all unauthorized devices. It does not, however, increase the difficulty of finding a wireless network.
B: WPA-Personal, also referred to as WPA-PSK (Pre-shared key) mode, is designed for home and small office networks and doesn’t require an authentication server. Each wireless network device authenticates with the access point using the same 256-bit key generated from a password or passphrase. Using this option will not decrease the chances of discovering the wireless network.
D: Using this option will not decrease the chances of discovering the wireless network in use.

QUESTION 47
Which of the following wireless security technologies continuously supplies new keys for WEP?
A. TKIP
B. Mac filtering

C. WPA2
D. WPA
Correct Answer: A Explanation
Explanation/Reference:
TKIP is a suite of algorithms that works as a “wrapper” to WEP, which allows users of legacy WLAN equipment to upgrade to TKIP without replacing hardware. TKIP uses the original WEP programming but “wraps” additional code at the beginning and end to encapsulate and modify it.
Incorrect Answers:
B: Networks can use MAC address filtering, only allowing devices with specific MAC addresses to connect to a network. It does not continuously supply new keys
for WEP.

C: WPA2 makes use of Counter Mode with Cipher Block Chaining Message Authentication Code Protocol (CCMP) and is a more secure standard that WEP or
WPA.

D: WPA replaces WEP, and also uses TKIP.

QUESTION 48
A network administrator has been tasked with securing the WLAN. Which of the following cryptographic products would be used to provide the MOST secure environment for the WLAN?
A. WPA2 CCMP
B. WPA
C. WPA with MAC filtering

D. WPA2 TKIP
Correct Answer: A Explanation
Explanation/Reference:
CCMP is the standard encryption protocol for use with the WPA2 standard and is much more secure than the WEP protocol and TKIP protocol of WPA. CCMP provides the following security services: Data confidentiality; ensures only authorized parties can access the information Authentication; provides proof of genuineness of the user Access control in conjunction with layer management
Because CCMP is a block cipher mode using a 128-bit key, it is secure against attacks to the 264 steps of operation.
Incorrect Answers:
B: The Wi-Fi Alliance intended WPA as an intermediate measure to take the place of WEP pending the availability of the full IEEE 802.11i standard. The WPA protocol implements much of the IEEE 802.11i standard. Specifically, the Temporal Key Integrity Protocol (TKIP) was adopted for WPA. WEP used a 40-bit or 104-bit encryption key that must be manually entered on wireless access points and devices and does not change. TKIP employs a per-packet key, meaning that it dynamically generates a new 128-bit key for each packet and thus prevents the types of attacks that compromised WEP. WPA also includes a message integrity check. This is designed to prevent an attacker from capturing, altering and/or resending data packets. This replaces the cyclic redundancy check (CRC) that was used by the WEP standard. CRC’s main flaw was that it did not provide a sufficiently strong data integrity guarantee for the packets it handled. Well tested message authentication codes existed to solve these problems, but they required too much computation to be used on old network cards. WPA uses a message integrity check algorithm called Michael to verify the integrity of the packets. Michael is much stronger than a CRC, but not as strong as the algorithm used in WPA2.
C: WPA even with the added security of MAC filtering is still inherently less secure than WPA2.
D: CCMP is the standard encryption protocol for use with the WPA2 standard and is much more secure than the TKIP protocol of WPA.

QUESTION 49
An access point has been configured for AES encryption but a client is unable to connect to it. Which of the following should be configured on the client to fix this issue?
A. WEP
B. CCMP
C. TKIP
D. RC4
Correct Answer: B Explanation
Explanation/Reference:
CCMP is an encryption protocol designed for Wireless LAN products that implement the standards of the IEEE 802.11i amendment to the original IEEE 802.11 standard. CCMP is an enhanced data cryptographic encapsulation mechanism designed for data confidentiality and based upon the Counter Mode with CBC-MAC (CCM) of the AES standard.
Incorrect Answers:
A: WEP is based on RC4, and does not use AES.
C: TKIP is a basis for WPA.
D: RC4 is the basis of WEP.

A. Placement of antenna
B. Disabling the SSID
C. Implementing WPA2
D. Enabling the MAC filtering
Correct Answer: A Explanation

Explanation/Reference:
You should try to avoid placing access points near metal (which includes appliances) or near the ground. Placing them in the center of the area to be served and high enough to get around most obstacles is recommended. On the chance that the signal is actually traveling too far, some access points include power level controls, which allow you to reduce the amount of output provided.
Incorrect Answers:
B: This option would “cloak” the network, not limit its signal strength.

C: This deals with authentication and would not make sure that the network is inaccessible from the parking area.

D: This would require clients to furnish the security administrator with their device’s MAC address.

QUESTION 58
An administrator wants to establish a WiFi network using a high gain directional antenna with a narrow radiation pattern to connect two buildings separated by a very long distance. Which of the following antennas would be BEST for this situation?
A. Dipole
B. Yagi
C. Sector
D. Omni

Correct Answer: B Explanation
Explanation/Reference:
A Yagi-Uda antenna, commonly known simply as a Yagi antenna, is a directional antenna consisting of multiple parallel dipole elements in a line, usually made of metal rods. It consists of a single driven element connected to the transmitter or receiver with a transmission line, and additional parasitic elements: a so-called reflector and one or more directors. The reflector element is slightly longer than the driven dipole, whereas the directors are a little shorter. This design achieves a very substantial increase in the antenna’s directionality and gain compared to a simple dipole.
Incorrect Answers:
A: The 15 cm long vertical element you see on most Wi-Fi equipment is actually a dipole antenna. It consists of two elements and is popular because of its omnidirectional radiation pattern.
C: A sector antenna is a type of directional microwave antenna with a sector-shaped radiation pattern. The word “sector” is used in the geometric sense; some portion of the circumference of a circle measured in degrees of arc. 60? 90?and 120?designs are typical, often with a few degrees ‘extra’ to ensure overlap and mounted in multiples when wider or full-circle coverage is required.
D: An omnidirectional antenna is designed to provide a 360-degree pattern and an even signal in all directions
