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?
A) IP Address of each machine is set incorrectly
B) subnet mask is wrong
C) no gateway address is set
D) DNS settings are incorrect

Question

Quizplus · Accepted Answer

Since pinging using the IP address is successful, it means that the network connectivity is fine. However, the fact that pinging using the hostname fails suggests that the DNS settings are incorrect, which is preventing machines from resolving domain names to IP addresses. Therefore, the most likely problem is with the DNS settings.
