Show answer & explanation
Correct answer: B
Concept
An Internet naming service links human-readable domain names with the numerical network addresses used to route traffic. DNS is the standard hierarchical and distributed naming system used for this name-to-address resolution.
Application
The expansion of the acronym DNS is “Domain Name System.” It identifies the naming system used for domain-to-address resolution.
Contrast
Dynamic Name System resembles the term dynamic DNS, which refers to updating DNS records when address information changes; it is not the expansion of DNS.
Distributed Name System describes an architectural property. DNS operates in a distributed manner, but this phrase is not the expansion of the acronym.
None of these does not apply because a standard expansion is present among the choices.
Result
Therefore, DNS stands for Domain Name System.
