What are two modules of the CCX Lite program? (Choose two.) A. foundation
B. voice
C. RF power
D. roaming Answer: AB
Explanation:
In summer 2011, Cisco separated the CCX features into four subfamilies to help vendors integrate only those features that are needed for their specific wireless clients (called application-specific devices, which are devices built for a specific function [for example, barcode scanners or VoWLAN phones] and therefore do not need all the CCX features that a data laptop would need). This is called the CCX Lite program, with four components:
QUESTION 222
What are two security threats to wireless networks? (Choose two.)
A. ad-hoc networks
B. client misassociation
C. port redirection
D. cross-site scripting Answer: AB
Explanation:
An ad hoc network is a collection of wireless clients that form a network amongst themselves without the use of an AP. As far as network administrators are concerned, ad hoc wireless networks are uncontrolled. If they do not use encryption, they may expose sensitive data to outside eavesdroppers. If a device is connected to a wired network and has bridging enabled, an ad-hoc network may also function like a rogue AP. Additionally, ad-hoc networks can expose client devices to viruses and other security vulnerabilities. For these reasons, many administrators choose to prohibit ad-hoc networks.
Valid Client Misassociation:
This feature does not detect attacks, but rather it monitors authorized (valid) wireless clients and their association within the network. Valid client misassociation is potentially dangerous to network security. The four types of misassociation that we monitor are:

QUESTION 223
In a network with a deployed Cisco WLC, which two entities must be configured with the shared secret key for 802.1X authentication? (Choose two.)
A. WLC
B. RADIUS server
C. AP
D. supplicant
E. wireless client Answer: AB
Explanation:
The WLC needs to be configured in order to forward the user credentials to an external RADIUS server. The external RADIUS server then validates the user credentials and provides access to the wireless clients.

Which statement describes spread spectrum technology in wireless communications? A. Signal is spread across optical pulses.
B. Signal is spread across variations of amplitudes.
C. Signal is spread across one frequency.
D. Signal is spread across a whole band of frequencies. Answer: D
Explanation:
spread-spectrum techniques are methods by which a signal with a particular bandwidth is deliberately spread in the frequency domain, resulting in a signal with a wider bandwidth. Spread spectrum generally makes use of a sequential noise-like signal structure to spread the normally narrowband information signal over a relatively wideband (radio) band of frequencies.

QUESTION 230
Which type of basic radiation pattern does a Yagi antenna have?
A. circular
B. semicircular
C. straight line
D. cone Answer: D
Explanation:
High gain directional antennas: A point to point high gain antenna is a directional antenna that has a focused radiation pattern. The radiation pattern is typically a cone 10 to 30 degrees wide.
A yagi and a parabolic dish are examples of high gain directional antennas.

D. VLAN 1 Answer: A
Explanation:
Assigning the IP Address to the BVI
When you assign an IP address to the access point by using the CLI, you must assign the address to the bridge-group virtual interface (BVI). Beginning in a privileged EXEC mode, follow these steps to assign an IP address to the access point BVI using the access point console port.

QUESTION 235
What does RF determine?
A. cycle pattern size
B. how often a wave occurs
C. signal size
D. quantity of energy injected in a signal Answer: B
Explanation:
RF communication works by creating electromagnetic waves at a source and being able to pick up those electromagnetic waves at a particular destination. These electromagnetic waves travel through the air at near the speed of light. The wavelength of an electromagnetic signal is inversely proportional to the frequency; the higher the frequency, the shorter the wavelength.

QUESTION 238
You are configuring SNMPv1/v2c on a WLC. What should you do for improved security?
A. Remove the default SNMPv1 community.
B. Remove the default SNMPv1 and SNMPv2 communities.
C. Remove the default SNMPv2 community.
D. Remove the default SNMPv3 users. Answer: B
Explanation:
The controller has commonly known default values of "public" and "private" for the read-only and read-write SNMP community strings. Using these standard values presents a security risk. If you use the default community names, and since these are known, the community names could be used to communicate to the controller using SNMP. Therefore, we strongly advise that you change these values.
Step 1
Choose Management and then Communities under SNMP. The SNMP v1 / v2c Community page appears.
Step 2
If "public" or "private" appears in the Community Name column, hover your cursor over the blue drop-down arrow for the desired community and choose Remove to delete this community.
Step 3
Click New to create a new community. The SNMP v1 / v2c Community > New page appears.
Step 4
In the Community Name text box, enter a unique name containing up to 16 alphanumeric characters. Do not enter "public" or "private."
Step 5
In the next two text boxes, enter the IPv4/IPv6 address and IP Mask/Prefix Length from which this device accepts SNMP packets with the associated community and the IP mask.
Step 6
Choose Read Only or Read/Write from the Access Mode drop-down list to specify the access level for this community.
Step 7
Choose Enable or Disable from the Status drop-down list to specify the status of this community.
Step 8
Click Apply to commit your changes.
Step 9
Click Save Configuration to save your settings.
Step 10
Repeat this procedure if a "public" or "private" community still appears on the SNMP v1 / v2c Community page.
QUESTION 239
Which spread spectrum technique uses 11-bit chips to transmit 1 bit of data over a 22-MHz channel?
A. DSSS
B. FHSS
C. OFDM
D. MIMO
E. CCK Answer: A
Explanation:
For every 0 or 1 you want to send, DSSS generates a code representing that 0 or that 1. This code, also called symbol or chip, can be a sequence of up to 11 bits (this is called the Barker 11 code), and these 11 bits are sent in parallel over the 22 MHz channel. You can lose up to nine of these 11 bits due to interferences and still understand whether the code sent was supposed to represent a 0 or a 1.
QUESTION 240
The network administrator has used VLANs to separate VoIP frames from data frames in the wired network. What must the administrator use to separate those frames in the wireless network?
A. multiple SSIDs
B. multiple authentications
C. multiple WEP or WPA keys
D. multiple channels
E. multiple 802.11 radios (a, b, g, n) Answer: A
Explanation:
Multiple IEEE 802.11 service set identifiers (SSIDs) allow you to create different levels of network access and to access virtual LANs (VLANs).You can configure up to 16 separate SSIDs to support up to 16 VLANs. Each VLAN can have a different wireless security configuration so that the devices that support the latest Cisco security enhancements can exist alongside legacy devices. This additional access point functionality enables a variety of users having different security levels to access different parts of the network.
