CRW2602 MCQ CERTIFICATION EVALUATION
EXAM 2026 QUESTIONS WITH ANSWERS
GRADED A+
◉ What is WiMAX and it IEEE? Answer: -Worldwide Interoperability
for Microwave Access
-IEEE 802.16 WWAN
◉ In cellular broadband there are two types of cellular networks, what
are they? Answer: Global System for Mobile (GSM) and Code Division
Multiple Access (CDMA).
GSM is internationally recognized, while CDMA is primarily used in the
US.
◉ Typically, it is used by rural homeowners and businesses where cable
and DSL are not available. It is usually more expensive and requires a
clear line of sight. Answer: Satellite Broadband
◉ What is the 802.11 WLAN? Answer: WiFi/wireless devices are based
on IEEE 802.11
set of protocols and wireless local area network (WLAN) Wi-Fi
computer communication in various frequencies
,-Radio frequency is 2.4 GHz
◉ What is the 802.11a? Answer: 5 Ghz frequency band
IEEE standard for transmitting data over a wireless network.
◉ What are the two allocated radio frequency in 802.11 wireless LANs?
Answer: 2.4GHz and 5GHz
◉ Which 802.11 standards exclusively use the 5 GHz radio frequency?
Answer: 802.11a
802.11ac
◉ Which of the wireless networks typically uses lower powered
transmitters for short ranges? Answer: WPAN
◉ In wireless, what does AP stand for? Answer: Access Point
◉ What does SSID stand for? Answer: shared service set identifier
(SSID)
◉ The wireless router advertises its wireless services by sending
______________containing its shared service set identifier (SSID).
Answer: Beacons
,◉ What does QoS stand for and what does it do? Answer: Quality of
Service
is a feature of routers and switches which prioritizes traffic so that more
important traffic can pass first.
◉ What does WAP stand for and what is it exactly? Answer: Wireless
Access Point
more generally just an access point, is a networking hardware devices
that allows other Wi-Fi devices to connect to a wired network.
◉ What does Wi-Fi stand for? Answer: Wireless Fidelity
technically, this is not the case. Wi-Fi is simply a trademarked term
meaning IEEE 802.11x.
◉ What is an Autonomous AP? Answer: -Standalone devices like a
home router. Where the entire WLAN configuration resides on the
device.
-Sometimes called thick APs
-do not require a controller to control the AP and it use WLSE for
management software
-use for a network that requires only a couple of access points.
◉ What does WLC stand for? Answer: Wireless LAN Controller
, ◉ What does AS stand for? Answer: Autonomous System
◉ What are Controller-based APs? Answer: -These devices require no
initial configuration and are often called lightweight APs (LAPs).
-Also called thin APs
-Centralized management, configuration, encryption, updates and policy
settings through a centralized controller
◉ LAPs. Answer: Lightweight Access Points
◉ LWAPP. Answer: Light Weight Access Point Protocol
◉ What is another name for LAPs? Answer: Controller-based APs
◉ LAG. Answer: Link Aggregation Group
◉ What is MIMO? Answer: Multiple Input Multiple Output.
Uses multiple antennas to increase available bandwidth for IEEE
802.11n/ac/ax wireless networks. Up to eight transmit and receive
antennas can be used to increase throughput.
◉ Which of the following components are integrated in a wireless home
router?
