H19-338 Exam Dumps - Huawei Certification Questions and Answers

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.

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.

SDR (Software Defined Radio) is a technology that can be used to switch the number of RFs (Radio Frequencies) dynamically. According to the Huawei AirEngine Wi-Fi 6 Solution White Paper, SDR enables an AP to dynamically switch between 2.4 GHz and 5 GHz bands based on the number of users and service requirements, improving spectrum utilization and user experience.

AirEngine 6760R-51E is a Wi-Fi 6 AP designed for rail transit scenarios. It supports 8x8 MU-MIMO and eight spatial streams, achieving a rate of up to 5.95 Gbit/s2. AirEngine 6761-21T is a Wi-Fi 6 AP designed for indoor scenarios such as offices and classrooms. AirEngine 6760-X1E is a Wi-Fi 6 AP designed for indoor scenarios such as hotels and shopping malls. AirEngine 6760-51EI is a Wi-Fi 6 AP designed for indoor scenarios such as stadiums and exhibition halls.

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.

Compared with common Ethernet, the NOF+ scenario greatly improves usability and reliability. According to the Huawei CloudFabric Data Center Network Solution White Paper, NOF+ (Network-Oriented Fabric+) is a data center network architecture that supports both Layer 2 and Layer 3 connectivity between servers and leaf nodes. NOF+ uses VXLAN technology to create overlay networks on top of theunderlay network, which improves network scalability, flexibility, and security. NOF+ also uses M-LAG technology to provide link redundancy and load balancing between leaf nodes and servers, which improves network availability and performance.

The free mobility function allows users to obtain the consistent network access policy regardless of their location and IP address, but it does not require the network to be made up entirely of Huawei devices. According to the Huawei CloudCampus Solution Description, 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.
