Authentic Huawei Certification Exam H19-338 Questions Answers

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.

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.
