,1. Multiple Choice: What is the maximum data rate
supported by IEEE 802.11n?
a) 150 Mbps
b) 300 Mbps
c) 600 Mbps
d) 1 Gbps
Correct Answer: c) 600 Mbps
Rationale: IEEE 802.11n, also known as Wi-Fi 4, can
theoretically support up to 600 Mbps under optimal
conditions, using multiple spatial streams and channel
bonding.
2. Fill-in-the-Blank: The ________ protocol is used to
assign IP addresses to devices in a wireless network.
Correct Answer: DHCP (Dynamic Host Configuration
Protocol)
Rationale: DHCP is used to dynamically assign IP
addresses to devices on a network, allowing them to
communicate with other devices and access the internet.
3. True/False: In wireless networking, the term 'roaming'
refers to the ability of a user to move from one access point
to another seamlessly.
Correct Answer: True
Rationale: Roaming allows a user to move across
different access points without losing connection, which is
essential for mobile devices in large networks.
4. Multiple Response: Which of the following are considered
as non-overlapping channels in 2.4 GHz Wi-Fi? (Select all

, that apply)
a) Channel 1
b) Channel 6
c) Channel 11
d) Channel 13
Correct Answers: a) Channel 1, b) Channel 6, c) Channel
11
Rationale: In the 2.4 GHz band, channels 1, 6, and 11 are
widely recognized as non-overlapping and can be used
simultaneously in the same area without interference.
5. Multiple Choice: Which modulation technique is used by
IEEE 802.11ac?
a) BPSK
b) QPSK
c) 16-QAM
d) 256-QAM
Correct Answer: d) 256-QAM
Rationale: IEEE 802.11ac, also known as Wi-Fi 5, uses
256-QAM to increase data rate by encoding more bits per
symbol.
6. Fill-in-the-Blank: The process of combining multiple
signals to increase data rates in wireless networking is
called ________.
Correct Answer: MIMO (Multiple Input Multiple Output)
Rationale: MIMO technology involves using multiple
antennas at both the transmitter and receiver to improve
communication performance.
7. True/False: Wi-Fi Protected Access 3 (WPA3) is less
secure than its predecessor WPA2.
Correct Answer: False
