To answer this question, we need to understand what a DMZ (Demilitarized Zone) is.
Option A) DMZ is the place where customers servers are deployed - This option is incorrect. While it is true that servers can be deployed in a DMZ, a DMZ itself is not specifically for customer servers.
Option B) DMZ is an area where all the protocols are allowed to pass through - This option is incorrect. A DMZ does not allow all protocols to pass through. It is designed to allow only specific protocols or services that are necessary for external communication.
Option C) A semi-trusted network zone that separates the untrusted internet from the company's trusted internal network - This option is correct. A DMZ is a network segment that acts as a buffer zone between an organization's trusted internal network and the untrusted external network (such as the internet). It is designed to provide an additional layer of security by isolating externally accessible services from the internal network.
Option D) DMZ is cyber warfare terminology - This option is incorrect. While the term "DMZ" may be used in the context of cyber warfare, in the context of computer networks, a DMZ refers to a specific network configuration.
The correct answer is C) A semi-trusted network zone that separates the untrusted internet from the company's trusted internal network. This option is correct because it accurately describes the purpose and function of a DMZ.
