An employee has contacted the IT Support call center where you work. They are complaining that they are unable to access any web pages other than the internal intranet site. Which option is the least likely to cause this issue?
Remember the question says LEAST LIKELY. The questions states that internal web servers work but external ones do not. If wireless were the issue nothing would work at all. The issue is more likely to be related to external DNS, a firewall or an issue with the proxy used to connect outside the local network.
