Question 26

DHCP is used to assign IP addresses to hosts on a network.

Dynamic Host Configuration Protocol (DHCP) is the service responsible for automatically assigning IP addresses to devices on a network, ensuring that each device can communicate effectively within the network.

A) VLAN

A Virtual Local Area Network (VLAN) is a technology that allows the segmentation of a physical network into smaller, logical networks. While VLANs improve network management and efficiency, they do not handle the assignment of IP addresses to hosts.

B) DHCP

DHCP (Dynamic Host Configuration Protocol) is specifically designed to allocate IP addresses and configure network settings automatically for devices on a network. This service simplifies network administration and helps prevent IP address conflicts.

C) Syslog

Syslog is a protocol used for logging information about system events and messages from various devices in a network. While it is useful for monitoring and troubleshooting, it does not assign IP addresses to hosts.

D) DNS

The Domain Name System (DNS) translates human-readable domain names into IP addresses, enabling users to access websites and services. However, DNS does not assign IP addresses to devices; this function is performed by DHCP.

Conclusion

DHCP is the definitive service for assigning IP addresses to hosts on a network, making it the correct answer. The other options—VLAN, Syslog, and DNS—serve different purposes and do not perform the critical function of IP address allocation.
