Depending on the geographical coverage, networks can be classified into local area networks (LANs), wide area networks (WANs), and metropolitan area networks (MANs) between LANs and WANs.

Correct Answer:A
Network Classification Based on Geographical Coverage:
Networks are categorized based on their geographical scope into three primary types: Local Area Network (LAN):Covers a small geographic area, such as a single building or campus.
Metropolitan Area Network (MAN):Covers a larger area than a LAN, typically spanning a city or metropolitan region. It serves as an intermediate between LANs and WANs.
Wide Area Network (WAN):Covers a large geographic area, often spanning multiple cities, countries, or continents.
Role of MANs:MANs act as a bridge between LANs and WANs, providing connectivity for organizations that need to connect multiple LANs within a city or region.
Conclusion:The statement is correct because networks are indeed classified into LANs, MANs, and WANs based on their geographical coverage.

Huawei's CloudWAN 3.0 solution propels WANs into the intelligent cloud-network era. Which of the following are the key highlights of CloudWAN 3.0?

Correct Answer:ABCE
Huawei'sCloudWAN 3.0solution introduces several innovative features to modernize wide- area networks (WANs):
One-click fast scheduling:Simplifies resource allocation and improves efficiency using SDN and intelligent algorithms.
One-fiber multipurpose transport:Enables multiple services (e.g., Internet, private lines) to share a single fiber, reducing costs.
One-network wide connection:Provides seamless connectivity across diverse locations and devices.
One-hop cloud access:Ensures direct and efficient access to cloud services, reducing latency.
The option"One-click maintenance"is not explicitly highlighted as a key feature of CloudWAN3.0. While maintenance tools exist, they are not marketed as a core highlight of this solution.
