CWS Wireless Technologies & Network Fundamentals

Question 1

Which frequency band is commonly used in Wi-Fi networks?

Accepted Answer

2.4 GHz

Answer

The 2.4 GHz frequency band is one of the most common bands used for Wi-Fi networks (alongside 5 GHz). It offers a wider range and better penetration through walls compared to 5 GHz, though it typically has lower data rates and is more susceptible to interference from other devices.

Question 2

What does SSID stand for?

Accepted Answer

Service Set Identifier

Answer

SSID stands for Service Set Identifier. It is the name of a Wi-Fi network that users see when they search for available networks. It acts as a unique identifier for a wireless local area network (WLAN).

Question 3

What is the purpose of a wireless access point?

Accepted Answer

To enable wireless connectivity

Answer

A wireless access point (WAP) is a networking hardware device that allows Wi-Fi compliant devices to connect to a wired network. It acts as a central hub for wireless devices, enabling them to communicate with each other and access the internet without physical cables.

Question 4

Which of the following is a wireless encryption protocol?

Accepted Answer

WPA2

Answer

WPA2 (Wi-Fi Protected Access II) is a robust and widely adopted security protocol used to secure wireless computer networks. It provides strong encryption and authentication, protecting data transmitted over Wi-Fi from unauthorized access. HTTP, FTP, and SMTP are application-layer protocols, not encryption protocols.

Question 5

Which device assigns IP addresses in a wireless network?

Accepted Answer

DHCP Server

Answer

A DHCP (Dynamic Host Configuration Protocol) server automatically assigns IP addresses and other network configuration parameters to devices connected to a network. This simplifies network management by eliminating the need to manually configure each device's IP address, ensuring efficient network operation.
