76. An expanding company has decided to use a wide area network to share information among its many offices. What is a benefit of using this type of network?
Answer: C
Wide area networks can be used on a global scale.
A significant benefit of using a wide area network (WAN) is its ability to connect multiple offices across vast geographical distances, enabling the sharing of information on a global scale.
A) Does not require data encryption
This option is incorrect because while a WAN may not inherently require data encryption, it is often necessary to implement encryption to protect sensitive information transmitted over large distances. Security measures are crucial in WANs to safeguard data from potential breaches.
B) Uses cabled connections to prevent attacks
This option is misleading as WANs can utilize various types of connections, including wireless. While cabled connections may provide certain security advantages, they are not a defining characteristic of WANs and do not inherently prevent attacks.
C) Can be used on a global scale
This option is correct as WANs are specifically designed to connect networks over large distances, including international boundaries. This capability allows companies to effectively manage their operations and communications across multiple locations worldwide.
D) Relies on a peer-to-peer architecture
This option is incorrect because WANs typically rely on a client-server architecture rather than a peer-to-peer model. Peer-to-peer networks are more common in local area networks (LANs) and do not scale effectively for the extensive reach of WANs.
Conclusion
The correct answer highlights the global scalability of wide area networks, which is essential for companies with multiple offices. Other options fail to accurately describe WAN characteristics, focusing instead on aspects that do not define the network's primary advantages, emphasizing the unique utility of WANs in connecting distant locations.
