Refer to the exhibit. What does the host do when using the IPv4 Preferred function?
The correct answer is B. It requests the same IPv4 address when it renews its lease with the DHCP server.. When a host uses the IPv4 Preferred function during DHCP, it specifically requests to renew its current IPv4 address lease from the DHCP server.

Why each option
When a host uses the IPv4 Preferred function during DHCP, it specifically requests to renew its current IPv4 address lease from the DHCP server.
DNS servers are responsible for resolving domain names to IP addresses, not for assigning or renewing IP addresses, which is the role of DHCP.
The 'IPv4 Preferred' function refers to the DHCP client's behavior during lease renewal, where it attempts to retain the same IPv4 address it was previously assigned, signaling this preference to the DHCP server.
A client requests a specific preferred address, not a pool of addresses; the DHCP server manages the address pool from which addresses are allocated.
A statically assigned IPv4 address is manually configured and does not involve DHCP lease renewal or a 'preferred' function, as its address remains constant.
