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 wide area network (WAN) allows for the interconnection of various offices located in different geographical areas, enabling information sharing across vast distances. This capability is a significant advantage for expanding companies that need to maintain communication and access to shared resources internationally.
A) Does not require data encryption
This option is incorrect as it implies a lack of security measures, which is not a benefit of WANs. In fact, data encryption is often necessary in WANs to protect sensitive information transmitted over large distances, especially when the network spans multiple locations.
B) Uses cabled connections to prevent attacks
While it is true that some WAN implementations may use cabled connections for security, this statement is misleading as WANs can also utilize wireless connections. The primary benefit of WANs is not specifically the type of connection used but their ability to connect remote sites.
C) Can be used on a global scale
This option is correct because WANs are designed to connect multiple networks over large distances, including across different countries and continents. This scalability allows organizations to operate efficiently on a global level, facilitating collaboration and resource sharing among distant offices.
D) Relies on a peer-to-peer architecture
This option is incorrect since WANs typically do not rely on a peer-to-peer architecture. Instead, they often utilize a client-server model or a combination of hierarchical topologies to manage and facilitate communication across diverse locations effectively.
Conclusion
The ability of wide area networks to operate on a global scale is a critical benefit that supports the needs of expanding companies. In contrast, the other options either misrepresent the functionality of WANs or highlight aspects that do not pertain to their primary advantages. Thus, option C stands out as the only choice that accurately reflects a significant benefit of using a WAN.
