Question 1

What is the purpose of VLANs in networking?

Accepted Answer

To segment a network into smaller, isolated networks

Answer

VLANs (Virtual Local Area Networks) are used to logically segment a single physical network into multiple distinct broadcast domains. This segmentation improves network performance by reducing broadcast traffic and enhances security by isolating different groups of devices. It allows for more flexible network management without requiring separate physical hardware for each segment.

Question 2

Which protocol is commonly used to dynamically assign IP addresses in a LAN?

Accepted Answer

DHCP

Answer

DHCP (Dynamic Host Configuration Protocol) is a network protocol specifically designed to automatically assign IP addresses and other network configuration parameters to devices on a network. This eliminates the need for manual configuration, simplifying network administration and ensuring efficient use of IP addresses. It is crucial for managing large and dynamic networks.
