Huawei HCSP-Presales-Storage H19-338 Exam Dumps: Updated Questions & Answers (October 2025)

Huawei Wi-Fi 6 products implement 10 ms ultra-fast roaming for all terminals, not only Huawei terminals, by introducing a cache mechanism, ensuring that there is no frame freezing during roaming. According to the Huawei AirEngine Wi-Fi 6 Solution White Paper, Huawei Wi-Fi 6 products use a cache mechanism to store user information on APs and switches, which enables fast authentication and reconnection when users roam between APs. This mechanism is compatible with all terminals that support IEEE 802.11k/v/r standards.

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.

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.

NE8000 F1A has 36 1GE ports. According to the NetEngine 8000 F1A Service Router Datasheet3, NE8000 F1A supports flexible combinations of up to 56 ports, including 36 x GE, 16 x 10GE, 2 x 40GE, and 2 x 100GE ports.

USG6680E, USG6712E, and USG6716E are firewalls that are recommended for data centers. They provide high-performance security protection, virtualization, and cloud management capabilities for data center networks. USG12004 and USG12008 are not firewalls, but routers that are designed for enterprise WANs.

RU-5G-101 supports independent deployment. According to the Huawei RU-5G-101 Datasheet2, RU-5G-101 is a high-speed wireless WAN access component that provides 5G wireless broadband access services for enterprises to implement wireless high-bandwidth data transmission. An RU-5G can be deployed independently to provide basic router functions.

The redundancy design of key components of the S12700E series switches can achieve 99.999% reliability. According to the CloudEngine S12700E Series Switches Datasheet, CloudEngine S12700E series switches support N+1 backup for MPUs, SFUs, CMUs, and power modules, as well as hot swapping for all components, ensuring high availability and reliability.

Free mobility cannot be deployed for traffic between VNs. Free mobility is supported only for policies in a VN. Communication between VNs can be directly implemented on the border node or through the external firewall. Free mobility is a feature that allows users to access network resources without changing their IP addresses or VLANs when they move within a VN. Communication between VNs requires inter-VN routing or firewall policies to ensure security and isolation.

The NE8000M1C supports dual AC/DC power modules. According to the NetEngine 8000 M1C Service Router Datasheet, NE8000M1C supports two power modules that can work in 1+1 redundancy mode. The power modules can be AC or DC power modules.

iFIT is a technology that can provide real-time service quality visualization and minutes-level fault demarcation. It can collect and analyze network traffic data, identify network problems, and optimize network performance. iFIT uses Telemetry to collect data from network devices, and uses Network Cloud Engine (NCE) to process and display the data. iFIT can also use In-band Network Telemetry (INT) to embed data into packets for more accurate measurement.
