100-150 Question 27
Single answerAn organization has a main office located in a city center and several branch offices spread across multiple cities. Each branch office has its own local network, and all these networks are connected to the main office's network to facilitate communication. Which type of network best describes the overall structure connecting all the branch offices to the main office?
- A
Local Area Network (LAN)
- B
Wide Area Network (WAN)
- C
Metropolitan Area Network (MAN)
- D
Campus Area Network (CAN)
Show answer and explanation
Correct answer: B
Explanation
The scenario involves connecting multiple branch offices located in different cities to the main office, which aligns with the definition of a Wide Area Network (WAN). WANs are designed to link geographically dispersed networks over long distances, making them the correct choice for this situation.
- A. Incorrect.
A Local Area Network (LAN) typically covers a small geographic area, such as a single building or office. It is not suitable for connecting networks across multiple cities.
- B. Correct.
A Wide Area Network (WAN) connects multiple networks over a large geographic area, such as multiple cities or even countries, which matches the scenario described.
- C. Incorrect.
A Metropolitan Area Network (MAN) covers a city or a large campus but is not designed for interconnecting networks spread across multiple cities.
- D. Incorrect.
A Campus Area Network (CAN) refers to a network that spans a single campus or a limited geographic area, such as a university or business complex, and is not applicable to this scenario.
