WLAN is a wireless local area network constructed using wireless technologies, including Wi-Fi, infrared, Bluetooth, and ZigBee.
- A. True
- B. False
Answer: B
Explanation:
WLAN (Wireless Local Area Network)specifically refers towireless networks based on the IEEE 802.11 standards, which arecommonly known as Wi-Fi. Whileinfrared, Bluetooth, and ZigBeeare also wireless technologies,they are not part of WLAN:
Wi-Fi (802.11)= WLAN
Bluetooth, ZigBee, Infrared= PAN or IoT technologies, not WLAN
Thus, grouping all these under WLAN isincorrect, making the correct answerFalse.

NEW QUESTION # 43
What are the characteristics of Segment Routing?
- A. It introduces the source routing mechanism conforming to SDN.
- B. Its deployment is dependent on LDP and RSVP.
- C. It reduces the number of protocols and extends IGP/BGP to support label distribution without depending on LDP or RSVP.
- D. Its deployment is dependent on the controller.
Answer: A,C
Explanation:
Segment Routing (SR) introduces a source routing model where the source node defines the path that packets take through the network by imposing a list of segments (instructions).
SR is aligned with SDN principles - the network is programmable and flexible.
SR does NOT depend on LDP or RSVP. Instead, SR uses extensions to IGP (OSPF or IS-IS) or BGP to distribute segment information.
SR simplifies the control plane by reducing the number of protocols needed for label distribution.
SR can work with or without a controller - the controller enhances path computation but is not mandatory for basic SR operation.

NEW QUESTION # 49
The free mobility solution allows a user on a campus network to obtain the same network access policy regardless of the user's location and IP address. When configuring a policy, the administrator does not need to pay attention to the IP address ranges of different users, but only needs to focus on the logical access relationships between users and servers.
- A. True
- B. False
Answer: A
Explanation:
Huawei's Free Mobility Solution decouples user identity from IP address and physical location.
Regardless of where a user accesses the campus network (wired or wireless), the same network access policies (such as ACLs, QoS, VLAN assignments) are dynamically applied based on the user identity.
Administrators only need to define access policies between user groups and server resources based on logical relationships (e.g., HR can access payroll servers) without worrying about IP addressing or user location.
This mechanism uses technologies like VXLAN-based campus network combined with policy association via iMaster NCE-Campus.

Huawei Wi-Fi 7 stands out for exclusive Wi-Fi Shield technology. Specifically, the AP sends extra interference signals as noise to ensure that only the target station (STA) can accurately receive data packets and signals cannot be demodulated at other locations. This prevents malicious users from intercepting the packets, ensuring campus network security.
- A. True
- B. False
Answer: A
Explanation:
Huawei's Wi-Fi 7 AirEngine APs integrate proprietary Wi-Fi Shield technology, which:
Uses spatial beamforming and artificial interference generation to emit "decoy" signals.
These signals act as deliberate noise, preventing nearby attackers from eavesdropping.
The intended recipient (STA) can still demodulate and receive data correctly using signal-processing algorithms.
This adds an additional physical layer of wireless security to protect against passive attacks.
