Following are two statements in the context of internet.
i. The Domain Name System (DNS) is primarily designed for authenticating user ‘login’ and ‘password’.
ii. The Domain Name System (DNS) translates human-readable domain names into numerical IP addresses.
In light of the above two statements, choose the correct option.
Only ii is correct
The Domain Name System (DNS) is often called the phone book of the internet. Computers on a network locate each other by numerical IP addresses such as 142.250.183.14, while people find it easier to remember names such as www.example.com. DNS is the distributed naming system that connects these two forms, so that a typed name can be turned into the address a computer actually needs.
Statement i is wrong. DNS is not designed to check a user login name or password. Verifying a user identity is the job of authentication systems and protocols such as login servers, Kerberos, RADIUS or the sign in pages of websites. Statement ii is right. When a name is entered in a browser, a resolver queries root, top level domain and authoritative name servers and returns the matching numerical IP address.
Since statement i is false and statement ii is true, the choice that says only i is correct is wrong, and the choice that says both are correct is also wrong. The choice that says both statements are incorrect fails because the second statement correctly describes the main role of DNS, which is name resolution.
Hence, Only ii is correct.
