Which action is the primary service provided by a host that is configured to operate as a Domain Name System (DNS) server on a small office/home office (SOHO) network?
It assigns dynamic IP addresses to devices that join the network.
It resolves human-readable domain names to their corresponding IP addresses so clients can find network resources.
It translates MAC addresses to IP addresses so routers can forward frames across subnets.
It encrypts web traffic and establishes secure channels between browsers and servers.
A DNS server's core job is to take the human-readable domain name (such as www.example.com) requested by a client and return the corresponding numerical IP address. This name-to-address resolution lets the client know where to send packets, enabling web browsing, email delivery, and other TCP/IP communications that rely on IP addressing. The other options describe functions performed by different services: translating MAC addresses to IP addresses is handled by ARP, encrypting web traffic is a role of HTTPS/TLS, and assigning dynamic IP addresses is done by DHCP.
