The concept that provides information about the location and types of servers is:

• A. DNS records
• B. A
• C. MX
• D. NS

Answer: (A)

DNS records define how to locate services and describe their roles across a domain. They store mappings that tell clients where a service resides (for example, which IP hosts web or other services) and what kind of server provides each service. An A or AAAA record gives the IP address of a host for web or other services. An MX record designates the mail server for a domain and its priority. NS records indicate which servers are authoritative for the domain, pointing to where the zone data is managed. SRV records can specify exact service endpoints, including port and protocol. By combining these records, the system communicates both the who (what type of server) and the where (its location). That’s why the concept described is DNS records.
