Show answer & explanation
Correct answer: D
Correct answer: DHCP is a protocol that allows both manual IP address assignment and automatic assignment.
What DHCP does: it automatically provides IP configuration (IP address, subnet mask, default gateway, DNS servers) to hosts and also supports manual/static assignment through reservations or manual configuration.
Automatic (dynamic) assignment: DHCP servers lease addresses to clients and manage lease times and renewals.
Manual/static assignment: administrators can assign fixed addresses or configure reservations on the DHCP server for specific hardware addresses.
Centralized management: DHCP centralizes network configuration so hosts can be configured automatically when they join the network.
Typical DHCP message exchange (DORA):
Discover: client broadcasts to find DHCP servers.
Offer: server offers an IP address and configuration.
Request: client requests the offered configuration.
Acknowledge: server confirms and assigns the lease.
In summary, the statement that DHCP allows both manual and automatic IP assignment correctly captures DHCP's role in network configuration.
