How does NIS provide functionality like a DNS server?

A.
It has a central host table.

B.
It forwards hostname to IP mapping requests.

C.
It carries out zone transfers.

D.
It contains configuration files.

Explanation:
A host table is a file that contains hostname-to-IP mappings. It is
used in the same way that DNS is, but it is a file that computers can use to map a
hostname to a specific IP address instead of a technology or a product. This is why
NIS is sometimes compared to DNS, because they both provide the necessary mechanisms
for computers to be able to uncover the IP address of a system.
