Final answer:
Dynamic DNS (DDNS) is the service that automatically manages DNS host records in conjunction with IP address lease changes handled by DHCP.
Step-by-step explanation:
The service that automatically creates and deletes DNS host records when an IP address lease is created or released is Dynamic DNS (DDNS). Unlike Dynamic NAT, which translates private IP addresses to public IP addresses, or DHCP Relay, which forwards DHCP messages between clients and servers on different networks, DDNS allows for the automatic update of a name server in the Domain Name System.
This means that when a device on the network gets an IP address from the Dynamic Host Configuration Protocol (DHCP), a corresponding DNS record is created or updated, and when the IP address lease is released or expires, the record is removed.
The correct answer to the question is C) Dynamic DNS.
