Question 1

What is the function of a wireless access point (AP)?

Accepted Answer

Connects wireless clients to a network

Answer

A wireless access point (AP) serves as a central hub that allows wireless-enabled devices, such as laptops and smartphones, to connect to a wired network. It broadcasts a Wi-Fi signal, creating a wireless local area network (WLAN) and enabling these clients to access network resources and the internet. Essentially, it bridges the wireless and wired parts of a network.

Question 2

Which hardware device manages IP address distribution?

Accepted Answer

DHCP server

Answer

A DHCP (Dynamic Host Configuration Protocol) server is responsible for automatically assigning IP addresses and other network configuration parameters to devices on a network. This automation simplifies network management by preventing IP address conflicts and ensuring that new devices can easily join the network without manual configuration. It's crucial for efficient network operation.

Question 3

What does a wireless LAN controller (WLC) do?

Accepted Answer

Manages multiple APs

Answer

A wireless LAN controller (WLC) centralizes the management, configuration, and security of multiple access points (APs) within a large wireless network. This allows network administrators to efficiently deploy, monitor, and troubleshoot the entire Wi-Fi infrastructure from a single point. WLCs are essential for scaling and maintaining robust enterprise wireless environments.

Question 4

What type of device connects computers within the same network?

Accepted Answer

Switch

Answer

A network switch is a fundamental device that connects multiple computers and other network devices within the same local area network (LAN). Unlike a hub, a switch intelligently forwards data packets only to the intended recipient device, based on their MAC addresses. This directed communication significantly improves network efficiency and performance.

Question 5

What role does network interface card (NIC) play?

Accepted Answer

Connects a device to a network

Answer

A Network Interface Card (NIC) is a crucial hardware component that enables a computer or other network device to connect to a network. It acts as an intermediary, translating data between the device's operating system and the network medium, whether it's a wired Ethernet cable or a wireless Wi-Fi signal. Without a NIC, a device cannot communicate over a network.
