Question

What are some reasons DNS is necessary? Check all that apply. It makes Internet website IP addresses accessible with human readable domain names. It maps local addresses to simple names without editing hosts files. It improves network throughput. It simplifies remote access.

Answer 1

Answer:

DNS is the de facto way of addressing computer services. We use names more often than we use IP addresses. If DNS were to fail we would have no way of finding the IP address, and would be unable to access any Internet services. DNS also virtualizes a service, making its IP address less significant.
