What are the different types of wireless frames that can be seen on an 802.11 network?

Data
Error
Control
Management
Alert

Correct Answer(s)

A. Data
A. Control
A. Management

Explanation

Wireless frames on an 802.11 network can be categorized into three main types: data, control, and management frames. Data frames are used to carry actual user data, such as emails or web pages. Control frames are responsible for managing the wireless connection, including tasks like acknowledging received data or requesting retransmissions. Management frames handle network management functions, such as authentication, association, and disassociation. The given answer correctly identifies the three types of frames commonly found in an 802.11 network.

What is MFP?

Multi-Function Printer - requires special care when adding to the wireless network
Multiple Factor Protocol - used for security in the wireless network
Mic Function Protection - used to make sure Mic's are not duplicated
Management Frame Protection - helps to detect man in the middle and deauthentication attacks

Correct Answer

A. Management Frame Protection - helps to detect man in the middle and deauthentication attacks

Explanation

MFP, Management Frame Protection can be used to help protect against a rogue AP sending out impersonations of valid management frames on a network. This can be done at the AP level or both the AP and client level to protect against man in the middle and deauthentication attacks.

What ratio of antenna gain to cable loss is allowed by the FCC?

2:3
5:3
1:1
1:2
3:1

Correct Answer

A. 1:1

Explanation

The FCC allows for a ratio of 1:1 between antenna gain and cable loss. This means that the amount of gain achieved by the antenna should be equal to the amount of loss experienced in the cable. This ensures that the signal strength remains balanced and within the acceptable limits set by the FCC.

Version 4.0
Version 3.1
Version 2.5
Version 2.0
Version 2.1

Correct Answer

A. Version 3.1

Explanation

A WLAN controller must be running version 3.1 or better to upgrade an autonomous AP to LWAPP.

Which of the below is a WPAN network technology capable of supporting devices within 10 feet of each other? (Choose all)

Bluetooth
WiMAX
Dect6
Zigbee
WiMAN

Correct Answer(s)

A. Bluetooth
A. Zigbee

Explanation

Bluetooth and Zigbee are both WPAN (Wireless Personal Area Network) technologies that are capable of supporting devices within 10 feet of each other. Bluetooth is a widely used technology for short-range wireless communication between devices, such as smartphones, tablets, and wireless headphones. Zigbee, on the other hand, is a low-power wireless communication technology commonly used in home automation and Internet of Things (IoT) applications. Both Bluetooth and Zigbee provide reliable and secure connections over short distances, making them suitable for devices that are in close proximity to each other.

Which wireless standard(s) use OFDM for modulation? (Choose any/all)

802.11n
802.1q
802.11a
802.11b
802.11g

Correct Answer(s)

A. 802.11a
A. 802.11g

Explanation

802.11a and 802.11g use OFDM (Orthogonal Frequency Division Multiplexing) as their modulation technique, which gives them greater data rates than 802.11b.

A wireless LAN is often an extension of the _________ of a wired network

Core
Distribution
Edge
Hub

Correct Answer

A. Edge

Explanation

A wireless LAN is often an extension of the edge of a wired network. The edge refers to the outermost part of a network where devices connect to the network. In the context of a wired network, the edge typically includes devices such as computers, laptops, and mobile devices that connect wirelessly to the network. Therefore, a wireless LAN extends the connectivity and accessibility of the wired network to these edge devices, allowing them to connect and communicate without the need for physical cables.

A wireless client connects to what via its WLAN RF connection?

A bluetooth headset
An access point
A wirless controller
An ethernet port

Correct Answer

A. An access point

Explanation

A wireless client connects to an access point via its WLAN RF connection. An access point is a device that allows wireless devices to connect to a wired network. It acts as a bridge between the wireless client and the network, providing a wireless connection for devices to access the internet or other resources. The access point receives and transmits data between the client and the network, allowing the client to communicate with other devices on the network.

A WLAN access point converts between 802._ and 802._ frames.

802.1, 802.3
802.11, 802.3
802.11ac, 802.11n
802.11i, 802.3

Correct Answer

A. 802.11, 802.3

Explanation

A WLAN access point converts between 802.11 and 802.3 frames. The 802.11 standard is specifically designed for wireless local area networks (WLANs), whereas the 802.3 standard is used for wired Ethernet networks. The access point acts as a bridge between these two types of networks, allowing devices connected to the WLAN to communicate with devices on the Ethernet network. By converting the frames between the two standards, the access point enables seamless communication and connectivity between wireless and wired devices.
