CCNA EXAM QUESTIONS WITH 100%
VERIFIED ANSWERS/////UPDATED
VERSION 2025
What is the IEEE of Bluetooth?=====802.15 WPAN
What is WiMAX and it IEEE?=====-Worldwide
Interoperability for Microwave Access
-IEEE 802.16 WWAN
In cellular broadband there are two types of cellular
networks, what are they?=====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.=====Satellite Broadband
What is the 802.11 WLAN?=====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?=====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?=====2.4GHz and 5GHz
Which 802.11 standards exclusively use the 5 GHz
radio frequency?=====802.11a
802.11ac
Which of the wireless networks typically uses lower
powered transmitters for short ranges?=====WPAN
In wireless, what does AP stand for?=====Access
Point
What does SSID stand for?=====shared service set
identifier (SSID)
The wireless router advertises its wireless services
by sending ______________containing its shared
service set identifier (SSID)=====Beacons
What does QoS stand for and what does it
do?=====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?=====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?=====Wireless Fidelity
technically, this is not the case. Wi-Fi is simply a
trademarked term meaning IEEE 802.11x.
,What is an Autonomous AP?=====-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?=====Wireless LAN
Controller
What does AS stand for?=====Autonomous System
What are Controller-based APs?=====-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=====Lightweight Access Points
LWAPP=====Light Weight Access Point Protocol
What is another name for LAPs?=====Controller-
based APs
LAG=====Link Aggregation Group
What is MIMO?=====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?
-Access Point
-Switch
-Router
-Range Extender=====Access Point, Switch, Router
What is infrastructure mode in WLAN?=====A
wireless router or AP connects wireless clients to a
wired distribution system.
What is API and what does the acronym stand for as
well?=====Application Programming Interface (API)
An API is software that allows other applications to
access its data or services. It is a set of rules
describing how one application can interact with
another, and the instructions to allow the interaction
to occur.
Data formats shared between smart devices often
use an Application Programming Interface (API
There are four types of web service
APIs=====Simple Object Access Protocol (SOAP)
Representational State Transfer (REST)
eXtensible Markup Language-Remote Procedure
Call (XML-RPC)
JavaScript Object Notation-Remote Procedure Call
(JSON-RPC)
Software-Defined Networking (SDN) is
what?=====The physical separation of the network
