The service that is designed to provide the functionality of warning employees when they try to visit untrusted sites, based on a list of valid websites, is generally related to web filtering or content filtering services. However, looking at the options provided:

A. **Hashing** - This is a method used to ensure data integrity and is not related to filtering websites.

B. **DNS server** - A DNS (Domain Name System) server resolves domain names to IP addresses. While it can be configured to block certain domains, it typically does not provide certificate warnings.

C. **Extensions** - This could refer to browser extensions that provide content filtering, but it's not a service on the network level.

D. **DHCP server** - A DHCP (Dynamic Host Configuration Protocol) server assigns IP addresses to devices on the network and does not handle web filtering.

Given these options, none of them directly describe a service that provides certificate warnings for untrusted sites. However, the closest functional component in a typical corporate environment for managing access to sites would often involve **DNS filtering** features that are available alongside DNS services.

That said, if forced to choose from the options provided without additional context regarding specific implementations, **B. DNS server** might be the most plausible choice, as DNS filtering can be done through the DNS server configuration. Nonetheless, a dedicated web filtering solution would be more appropriate for providing such warnings.
