What describes a network established by an organization that uses private IP address space and is commonly designed as a local area network?

• A. Public Network
• B. VPN
• C. Private Network
• D. Protocol

Answer: (C)

Private networks are built using private IP address ranges (such as 10.0.0.0/8, 172.16.0.0/12, or 192.168.0.0/16) and are typically designed as local area networks within an organization. These private addresses aren’t routable on the public Internet, which keeps internal traffic contained and makes address management simpler on a LAN. That combination—private IP space and a LAN design—defines a Private Network.

A public network would rely on public IPs and be exposed to the Internet. A VPN is a secure tunnel that can connect networks over untrusted networks, not the network type itself. A protocol is a rule set for communications, not a network type.
