Answer 2

Firewall is the special type gateway that can keep ‘external users’ from accessing resources on the ‘LAN users access the external info’.

Answer: Option (b)

Explanation:

A firewall gateway along with the specific TCP/IP connections always provides an end to end connectivity options. This special gateway can be used for configuring the network traffic, thus it could be initiated from secure network zone, if the communicating components are in various security levels.

Usually open ports in firewall gateway should be reduced to single connection or single port. The security policy used in Firewall security should establish a more secure connection zone rather than less secure zone.
