Which option must be enabled in a DHCP server for it to function properly?

• A. DHCP Option 82
• B. Interface address pool
• C. DHCP globally
• D. Global address pool

Answer: (C)

For a DHCP server to function properly, enabling DHCP globally is essential. When DHCP globally is enabled, it allows the server to provide IP addresses to devices on the network, managing the lease of addresses from its available pool. Without this essential configuration, the server would not offer any DHCP services, making it impossible for client devices to receive IP addresses automatically. While DHCP Option 82 is useful for relay agents and can aid in ensuring more intricate and secure deployments, it is not a requirement for all DHCP servers to provide basic functionality. The interface address pool is important as it specifies the range of addresses a server can issue, but it is not sufficient alone without the global DHCP feature. The global address pool refers to the overall collection of available IP addresses, which also cannot function without the global activation. Therefore, enabling DHCP globally is the foundational step required for a DHCP server to operate effectively.
