Answer: B
NEW QUESTION # 88
Which of the following statements about LAN-WAN convergence b false?
- A. LAN-side services at the core, aggregation and access layers provide authentication for wired and wireless users on the campus network
- B. WAN-side services set VPNs on the egress gateway for Interconnection between LAN sites
- C. You can configure interfaces and routes between the core switch and the egress gateways to achieve Interconnection between LAN and WAN services.
- D. The WAN-side controller can manage both LAN and WAN.
Answer: D
Explanation:
Explanation
The WAN-side controller can manage only WAN services, not LAN services. The LAN-side controller can manage both LAN and WAN services. This is because the LAN-side controller supports both SD-WAN and SD-Campus functions, while the WAN-side controller only supports SD-WAN functions.
NEW QUESTION # 89
Which of the following are key features provided by SmartRadio?
- A. Intelligent load balancing
- B. Enhanced distributed channel access (EDCA)
- C. Dynamic Frequency Assignment (DFA)
- D. Airtime fair scheduling
Answer: A,C,D
Explanation:
Explanation
SmartRadio is a technology that provides intelligent radio resource management for wireless networks.
SmartRadio includes several features, such as Dynamic Frequency Assignment (DFA), which automatically adjusts the frequency allocation based on the interference situation; Intelligent load balancing, which distributes users among APs based on user density and traffic load; and Airtime fair scheduling, which allocates airtime resources fairly among users with different rates. Enhanced distributed channel access (EDCA) is not a feature of SmartRadio, but a standard mechanism defined by IEEE 802.11e to provide QoS differentiation for wireless multimedia applications.

NEW QUESTION # 92
Free mobility is supported on a hybrid network consisting of Huawei and third-party devices, and the authentication point can be deployed on third-party devices.
- A. False
- B. True
Answer: B
Explanation:
Explanation
Free mobility is supported on a hybrid network consisting of Huawei and third-party devices, and the authentication point can be deployed on third-party devices. According to the Huawei CloudCampus Solution Description, free mobility is a feature that allows users to access network resources without changing their IP addresses or VLANs when they move within a virtual network (VN). Free mobility can be implemented on a hybrid network by using VXLAN tunneling technology and policy association.

NEW QUESTION # 94
Which of the following redundancy designs are supported by the NE8000 X4 and X8?
- A. MPU 1+1 backup
- B. PEM 1+1 backup
- C. SFU 7+1 backup
- D. Power supply 9+1 backup
Answer: A,B,C
Explanation:
Explanation
NE8000 X4 and X8 are high-end core routers designed for large-scale IP backbone networks, data centers, and metro networks . They support various redundancy designs to ensure high availability and reliability, such as MPU (Main Processing Unit) 1+1 backup, SFU (Switch Fabric Unit) 7+1 backup, and PEM (Power Entry Module) 1+1 backup . MPU 1+1 backup means that two MPUs work in active/standbymode and provide control plane redundancy . SFU 7+1 backup means that eight SFUs work in N+1 mode and provide data plane redundancy . PEM 1+1 backup means that two PEMs work in active/standby mode and provide power supply redundancy . The NE8000 X4 and X8 do not support power supply 9+1 backup, which is a feature of the NE8000 X16 router .
NEW QUESTION # 95
Which of the following technologies is not recommended for data centers?
- A. 802. 1x
- B. VXLAN
- C. M-LAG
- D. BFD
Answer: A
Explanation:
Explanation
The technology that is not recommended for data centers is 802.1x. This is because 802.1x is a port-based authentication protocol that requires each device to be authenticated before accessing the network. This can cause delays and complexity in data center environments where there are many devices and high-speed connections2
