DNS is a protocol used to?

Hand out IP addresses to network devices
Convert FQDNs to IPs
Access a directory service
Allow remote management of a device

The correct answer is: Convert FQDNs to IPs

DNS, or Domain Name System, is a protocol used to convert Fully Qualified Domain Names (FQDNs) to IP addresses. This is essential as humans find it easier to remember alphanumeric names rather than a string of numbers. Option A is incorrect because while DNS does provide IP addresses to network devices, it doesn't hand them out. Option C is incorrect because DNS does not access directory services, it simply performs a lookup to convert names to IPs. Option D is incorrect because while DNS allows for remote management, that is not its primary purpose. The main purpose of DNS is to translate domain names to IP addresses.
