Selected Answer: B
I'm going with B because all computers joining the network won't receive a valid IP address, preventing them from communicating with the network and the internet. A. Incorrect default gateway: An incorrect default gateway would prevent computers from communicating outside their local network (including the internet) but wouldn't necessarily stop them from obtaining an IP address from the DHCP server.
