What does DHCP do?

Resolves IP to MAC address
Converts FQDNs to IPs
Hands out IP addresses to network devices
Allows Microsoft systems to share resources

The correct answer is: Hands out IP addresses to network devices

DHCP stands for Dynamic Host Configuration Protocol and it is responsible for dynamically assigning IP addresses to network devices. Option A is incorrect because ARP (Address Resolution Protocol) resolves IP addresses to MAC addresses. Option B is incorrect because DNS (Domain Name System) converts FQDNs (Fully Qualified Domain Names) to IPs. Option D is incorrect because although DHCP is commonly used in Microsoft systems, it is not its main purpose and it is not exclusive to Microsoft systems. Therefore, option C is the most accurate answer as DHCP is specifically designed to hand out IP addresses and facilitate network connectivity.
