Free Practice Questions for Huawei H19-338 Exam

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 .

M-LAG (Multi-Chassis Link Aggregation Group) is the recommended networking mode for leaf switches. According to the Huawei CloudFabric Data Center Network Solution White Paper, M-LAG enables multiple leaf switches to form a logical device that provides high availability, load balancing, and simplified management.

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

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

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.

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

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.

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.
