Which of the following types of networks is most suitable for securely connecting geographically distant branches of a multinational company, while ensuring encrypted communications? 

A Wide Area Network (WAN) is the most appropriate network for connecting geographically distant branches of a multinational company. WANs can span countries and continents, making them suitable for organizations with offices worldwide. Importantly, WANs support encrypted communication, ensuring secure data transfer between distant branches. WANs often utilize public networks (such as the internet), but security is achieved through encryption methods like VPNs (Virtual Private Networks) or dedicated leased lines. The scalability and flexibility of WANs make them ideal for multinational corporations, allowing seamless, secure communication over long distances. Why Other Options are Incorrect: A) LAN (Local Area Network): LAN is limited to a smaller area, such as a building or campus, and is not suitable for connecting branches across different regions or countries. B) MAN (Metropolitan Area Network): MAN is designed for a city or metropolitan area, which is too limited in scope for multinational companies. C) CAN (Campus Area Network): CAN is typically used to connect several LANs within a campus, which is not adequate for linking distant branches across the globe. D) PAN (Personal Area Network): PAN is for very short-range communications (such as Bluetooth devices) and is not applicable to connecting organizational branches.
