Which platform supports domain name resolution (the service used to map domain names to IP addresses)?

• A. Domain Name System (DNS)
• B. Endpoint Security Solution (ESS)
• C. CSCS
• D. C3MS

Answer: (A)

Domain name resolution is the process of turning human-friendly domain names into the IP addresses computers use to locate resources on the network. The service that performs this mapping is the Domain Name System (DNS). When you type a domain into a browser, your device asks a DNS resolver to find the corresponding IP address. The resolver may query multiple servers in a hierarchy (root, top-level domain, and authoritative servers) and then returns the IP address so the connection can be established. DNS exists specifically to translate names into addresses, which is why it’s the correct choice. Endpoint Security Solution focuses on protecting devices from threats, not translating domain names to IPs. The other options, CSCS and C3MS, are not standard name-resolution services and do not perform DNS mappings, so they don’t fit this function.
