Question
A company is setting up a network and needs to assign IP addresses dynamically. Which protocol should they use?
A. DNS
B. DHCP
C. NAT
D. FTP
E. ARP
Answer
B. DHCP
Explanation
The Dynamic Host Configuration Protocol (DHCP) automatically assigns IP addresses to devices on a network.
The Dynamic Host Configuration Protocol (DHCP) is specifically designed to automatically assign IP addresses to devices on a network. When a device connects, it requests an IP address from the DHCP server, which then allocates an available address from its pool, along with other essential configuration details like subnet mask, default gateway, and DNS servers.
This process eliminates the need for manual IP address assignment, reduces configuration errors, and ensures efficient use of available addresses, especially in environments where devices frequently join or leave the network. DHCP supports both IPv4 and IPv6 and is widely used in networks of all sizes, from small offices to large enterprises.
Other protocols listed, such as DNS, NAT, FTP, and ARP, do not provide dynamic IP address assignment. DHCP remains the industry standard for this purpose.
