What is the main advantage of using DHCP in a network?

The primary benefit of utilizing DHCP (Dynamic Host Configuration Protocol) in a network is that it prevents IP address conflicts. DHCP automates the process of assigning IP addresses to devices on a network, ensuring that each device is assigned a unique IP address from a defined range or pool. This automation mitigates the risk of assigning the same IP address to multiple devices, which can lead to connectivity issues or network malfunctions. By managing IP address allocations automatically, DHCP helps maintain a stable and efficient network environment, reducing administrative errors that can occur with manual IP address assignments.

While the other choices have their merits, they do not align as closely with the core function of DHCP. For instance, faster data transmission is more related to network speed and bandwidth rather than address assignment protocols. Similarly, while using DHCP can streamline network management and reduce the likelihood of errors—which might indirectly lead to reduced operational costs—it is not primarily aimed at cost reduction. Lastly, while security can be enhanced in networks using various measures, DHCP itself does not inherently provide security improvements, although it can be configured to operate within a secure environment.
