Which type of information resides on a DHCP server?

A DHCP server maintains address pools and leases IP configuration to clients. The most basic information it holds is the list or range of available IP addresses that can be assigned from a pool, along with related options such as default gateway, DNS servers, domain name, and lease duration. It does not store public DNS name mappings; that is a DNS function. It does not normally store domain usernames and passwords; that belongs to directory or AAA systems. Static MAC-to-IP reservations can exist in DHCP, but the broad answer being tested is the available address pool. Cisco CCNA 200-301 v1.1 IP Services requires candidates to understand DHCP server, client, relay, pool, lease, exclusion, and default-router behavior. When a client sends DHCPDISCOVER, the server selects an address from the configured pool and offers it with network parameters. Therefore, the correct answer is A.
