Which protocol is used for name resolution on Linux workstations?

1. DHCP

2. DNS

3. FTP

4. SMB

The correct answer is: DNS

The protocol utilized for name resolution on Linux workstations is Domain Name System (DNS). DNS serves as a hierarchical system that translates human-friendly domain names (like www.example.com) into IP addresses that computers use to identify each other on the network. This essential process allows users to access websites and services using easily memorable names, rather than having to remember numerical IP addresses. When it comes to network communication, DNS plays a crucial role. It helps resolve names to addresses, enabling applications and services to locate resources on a network or the internet seamlessly. This is particularly significant in environments where dynamic IP addressing and complex network topologies are common. Other options, while relevant to network functionality, do not serve the specific purpose of name resolution. DHCP (Dynamic Host Configuration Protocol) is used primarily for assigning IP addresses to devices on a network. FTP (File Transfer Protocol) is focused on transferring files over the internet. SMB (Server Message Block) is mainly used for file sharing and network printing. Thus, among these options, DNS is clearly the correct answer for name resolution on Linux workstations.
