Which network type is not accessible from outside the organization by default?

• A. Internet
• B. Extranet
• C. Intranet
• D. LAN

Answer: (C)

The concept being tested is how access is controlled by network scope and boundaries. An intranet is a private network used inside an organization, housing internal websites, applications, and resources that are meant for internal users. By design, it isn’t accessible from outside the organization unless a controlled remote path is provided (such as a VPN or a secure gateway). This strict internal access policy is what makes it the best fit for “not accessible from outside by default.” In contrast, the Internet is public and accessible from outside, an extranet is a portion of the intranet extended to external partners with authentication, and a LAN is a local-area network inside a building or campus. While a LAN is also internal, the term intranet most directly conveys the idea of private resources that are not exposed to the broader Internet by default.
