Question

Almost immediately after a server migration project, employees are complaining that they can't reach the Internet. You sit down at a machine and try to ping a well-known website using the host name, which fails. You then try to ping a known public IP address, which succeeds. What is most likely the problem?

Answer 1

Answer:

DNS settings are incorrect.

Explanation:

DNS servers match domain names to their associated IP addresses.

When working properly, if one types a domain name into a browser, computer contacts current DNS server and asks what IP address is associated with the domain name. The computer then connects to the IP address and retrieves the right web page.

You try to ping a well-known website using the host name, which fails. You then try to ping a known public IP address, which succeeds; this means that DNS settings are not correct.
