Networking Fundamentals — Question 15

A network that separates an organization's private network from a public network is a/an:

Answer options

• A. Firewall
• B. Extranet
• C. Perimeter
• D. Internet

Correct answer: C

Explanation

The correct answer is C, Perimeter, which refers to the boundary that separates internal networks from external networks. A Firewall is a device that monitors and controls incoming and outgoing network traffic but does not define the separation itself. An Extranet is a controlled private network that allows access to outsiders, and the Internet is the global public network, not a separating entity.
