What term describes a private network that spans multiple sites and uses public infrastructure to connect, accessible to partner organizations?

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

Answer: (B)

Extranet is a private network extended to external partner organizations, allowing multiple sites to connect over public infrastructure such as the Internet while maintaining controlled access. This setup lets a company securely collaborate with suppliers, distributors, or customers across different locations. The Internet by itself is public, not restricted to partners; an intranet is confined to internal users; cloud refers to hosted services rather than a private network that connects multiple sites for external partners. So the description matches an extranet.
