H19-338 Huawei HCSP-Presales-Storage Free Practice Exam Questions (2025 Updated)

The switch that does not support iStack is S1730S-H. This is because the S1730S-H does not have any stack ports or support stack cards. The iStack technology allows multiple switches to be connected and managed as a single logical device, which improves network scalability and reliability.

The leader AP does not establish a CAPWAP tunnel with the fit AP. The leader AP communicates with the fit AP through the management VLAN, and the fit AP establishes a CAPWAP tunnel with the AC. In tunnel forwarding mode, user traffic needs to pass through the leader AP. In direct forwarding mode, user traffic is directly transmitted from the AP egress rather than from the leader AP. In tunnel forwarding mode, the leader AP can manage more fit APs than in direct forwarding mode.

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

iMaster NCE-FabricInsight is a network analysis platform that provides intelligent O&M for data center networks . It has the following features:

1-3-5 intelligent O&M: This is a methodology that enables network administrators to locate faults within 1 minute, identify root causes within 3 minutes, and rectify faults within 5 minutes . It uses AI algorithms and big data analysis to provide proactive fault prevention, rapid fault location, and intelligent fault recovery .

Network health check: This is a function that monitors the network status and performance in real time, and provides comprehensive network health reports and suggestions for improvement . It uses various indicators such as availability, reliability, latency, jitter, packet loss, and bandwidth utilization to evaluate the network health .

Flow analysis: This is a function that collects and analyzes the network traffic data, and provides granular visibility into the network flows and applications . It uses technologies such as sFlow, NetStream, and Telemetry to obtain the flow information, and supports features such as flow path tracing, flow quality analysis, flow anomaly detection, and flow optimization .

AI-scenario data visualization: This is a function that displays the network data in a visual and interactive way, and provides insights into the network behavior and trends . It uses technologies such as graph databases, natural language processing, and machine learning to present the network data in various scenarios, such as topology views, service views, device views, alarm views, and report views .

Capacity/traffic risk prediction: This is a function that predicts the future network capacity and traffic demand based on historical data and trend analysis, and provides suggestions for network planning and optimization . It uses technologies such as time series analysis, regression analysis, and neural networks to forecast the network growth and identify potential risks .

CloudEngine S5732-H series multi-GE switches do not deliver a switching performance of 1760 Gbit/s. According to the CloudEngine S5732-H Series Multi-GE Switches Datasheet, CloudEngine S5732-H series multi-GE switches deliver a switching performance of up to 336 Gbit/s.

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.

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.

Huawei CloudFabric solution has been awarded Gartner’s “Customer Choice” three times by March 2021. According to the Huawei CloudFabric Solution Wins Gartner Peer Insights Customers’ Choice for Third Consecutive Year article, Huawei CloudFabric solution received this honor in 2019, 2020, and 2021.

NE8000 M1A and F1A are not both 220 mm deep. According to the Huawei NetEngine 8000 M14 Routers Support Guide, NE8000 M1A is 220 mm deep, but NE8000 F1A is 400 mm deep.

CloudEngine S1270OE-O8 provides eight LPU slots, four SFU slots, two MPU slots, two CMU slots, and six power module slots1.

AirEngine 8760-Xi-PRO is Huawei’s flagship Wi-Fi 6 product that has a unique industrial design with features such as an 18-degree angle of tilt for network ports and optical ports, a shark fin bionic heat dissipation channel, and a removable cover for IoT card installation . These features are designed to improve the performance, reliability, and convenience of the product. Easy and flexible is not an industrial design feature of the AirEngine 8760-Xi-PRO, but rather a general description of its deployment and management capabilities .

The model that is not included in the CloudEngine S7700 family is S7709. The CloudEngine S7700 family consists of three models: S7703, S7706, and S7712. These are smart routing switches designed for next-generation enterprise networks, with features such as wired and wireless convergence, unified user management, quality awareness, and SVF 2.04

Each AP does not need to be designed to cover as large an area as possible in order to provide better coverage in a high-density scenario. According to the Huawei AirEngine Wi-Fi 6 Solution White Paper, in a high-density scenario, each AP should be designed to cover a small area with high signal strength and low interference, which can improve user experience and network capacity.

NE8000 M14 cannot be deployed in a 300 mm-deep cabinet. According to the Huawei NetEngine 8000 M14 Routers Support Guide1, the NE8000 M14 requires a cabinet with a depth of at least 800 mm.

The maximum single-radio rate supported by Wi-Fi 6 products is 9.6 Gbit/s. This is achieved by using 1024-QAM modulation, 160 MHz channel bandwidth, and 8 spatial streams1

The built-in LAN ports on all Huawei NetEngine AR6000/600 series routers can be used as WAN ports. According to the NetEngine AR6000 Series Enterprise Routers Product Overview, NetEngine AR6000/600 series routers support flexible WAN/LAN port configuration, which allows users to use any built-in LAN port as a WAN port.

Huawei AirEngine 8760X1-PRO is not Huawei’s flagship Wi-Fi 6 model. According to the Huawei AirEngine Wi-Fi 6 Solution White Paper, Huawei AirEngine 8760X1-PRO is a high-performance Wi-Fi 6 AP that supports 16 spatial streams and a rate of up to 10.75 Gbit/s, but it is not the flagship model. The flagship model is Huawei AirEngine 8760R-PRO, which supports 24 spatial streams and a rate of up to 16.13 Gbit/s.
