Which of the following parameters is not required if you want to communicate with a system on the same LAN?
  1. IP address
  2. Subnet mask
  3. MAC address
  4. Default gateway
Explanation
Answer - D - You need not configure the default gateway if you are configuring a system to communicate with a system on the same LAN.

Key Takeaway: The best example for this scenario would be to setup a communication between 2 computers as peers. In this case, you would only assign a private IP to these computers. The subnet mask will be assigned by default based upon the IP assigned. You need not configure the default gateway since the packets to be transferred do not reach the default gateway.
