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.

For USG6000F series firewalls, 10 virtual systems and 100 concurrent SSL VPN users are provided for free by default.
Correct Answer:B
Virtual Systems and SSL VPN Licenses:
Virtual systems allow a single firewall to act as multiple logical firewalls, each with its own policies and resources.
Concurrent SSL VPN users require licenses for secure remote access. Default Licensing for USG6000F Series:
By default, the USG6000F series providesfree licenses for 10 virtual systems. However,SSL VPN licenses are not included by defaultand must be purchased separately. Conclusion:The statement is FALSE because only 10 virtual systems are provided for free,
while SSL VPN licenses are not included by default. References:

In 2021, China Communications Standards Association (CCSA) released the IPv6 Enhanced standard system, and Huawei helped set up the IPv6 national standard team.
Correct Answer:A
In2021, theChina Communications Standards Association (CCSA)introduced theIPv6
Enhancedstandard system to driveIPv6+ adoption.
Huawei played a major role in the standardization process, contributing expertise in areas such asSRv6, network slicing, and intelligent O&M.
This initiativealigns with China's strategy to accelerate IPv6 deploymentfor next-generation networks.

WLAN is a wireless local area network constructed using wireless technologies, including Wi-Fi, infrared, Bluetooth, and ZigBee.
Correct Answer:B
A WLAN (Wireless Local Area Network) is specifically defined as a network that uses radio frequency (RF) technologies , primarily Wi-Fi, to provide wireless connectivity. While technologies like infrared, Bluetooth, and ZigBee are wireless communication methods, they are not part of the WLAN definition.
Wi-Fi : Operates in the 2.4 GHz and 5 GHz frequency bands and is the primary technology used in WLANs.
Infrared : Uses light waves for short-range communication and is not part of WLAN standards.
Bluetooth : Designed for short-range personal area networks (PANs), not LANs. ZigBee : Used for low-power, low-data-rate IoT applications, not WLANs.
Thus, the statement is FALSE , as WLANs are exclusively based on RF technologies like Wi-Fi.

Huawei Cloud Engine S12700E is front-to-back airflow design, improving the heat dissipation efficiency of the rack.
Correct Answer:A
Airflow Design in Data Center Switches:
Airflow design is critical for efficient heat dissipation in data center switches. Front-to-back airflow ensures that cool air enters from the front and hot air exits from the back, aligning with typical data center cooling systems.
Huawei Cloud Engine S12700E:
The S12700E series switches are designed with front-to-back airflow to improve heat dissipation efficiency. This design minimizes overheating risks and ensures stable operation in high-density environments.
Conclusion:The statement is TRUE because the S12700E series uses a front-to-back airflow design.
