A customer needs a router that will be able to handle all incoming and outgoing networking traffic independent of the rest of the building. The customer would like
the PCs to immediately connect to the Internet and network resources without any additional configuration. Which of the following should the technician do to meet
the requirements?
A.
Configure the router for DHCP.
B.
Configure the router for NAT.
C.
Configure the router for port forwarding.
D.
Configure the router for QoS.
Assuming B.

C and D are immediately disqualified. Port forwarding merely allows incoming traffic to be dedicated to a single computer/server/box. QoS allows priority of certain applications over others (SSL is more important than torrenting). DHCP assigns internal IP addresses, enabling computers to have their own IP address within the intranet. However, NAT makes the most sense as it’d be turning the internal IPs to a single public IP.
NAT is essentially a big man-in-the-middle proxy that funnels connections to save money. Read http://whatismyipaddress.com/nat

Answer is A. Main us of NAT is limit the number of public IP in a private network and that was never ask in the question.
