CorpServ is a small company with 14 client systems and a network printer. Because there are only a limited number of networked systems, you decide to use APIPA addressing for the network. With APIPA configured, all systems are able to communicate with each other, but you are having trouble configuring Internet access.
What is the likely cause of the problem?
A) The default gateway is not set on the client systems.
B) The default gateway is not set on the server.
C) Private addresses cannot directly communicate to hosts outside the local subnet.
D) All client systems must be rebooted.
E) The DNS server is unavailable to resolve internet host names.

Based on the scenario being described within the question it can be said that the likely cause of this problem would be that Private addresses cannot directly communicate to hosts outside the local subnet. Therefore since you are using APIPA (Automatic Private IP Addressing) which basically assigns private IP addresses to each machine then none of these machines will be able to communicate to outside hosts which is needed to connect to the internet.
