H19-338 Practice Exam Questions and Answers

next-generation NetEngine AR routers are intelligent edge routers that provide comprehensive services for enterprises, such as WAN access, SD-WAN, VPN, voice, video, security, cloud interconnection, and IoT . They have several strengths that differentiate them from other products in the market, such as:

Incorporating an industry-leading CPU+NP architecture, providing industry-leading L3 to L7 full-service efficient processing. The CPU+NP architecture combines the advantages of both CPU-based general-purpose processing and NP-based hardware acceleration, enabling high-performance processing of various services at different layers .

Incorporating iPath (application-based intelligent traffic steering & optimization) and A-FEC {no frame freezing or artifacts even at a 20% packet loss rate). iPath is a technology that intelligently steers traffic based on application types, quality requirements, link conditions, and policies, optimizing the user experience and resource utilization . A-FEC is a technology that enhances the error correction capability of video streams, ensuring smooth video transmission even under high packet loss scenarios .

Offering three times the industry average performance based on x86. The next-generation NetEngine AR routers use x86 processors that deliver high computing power and scalability, enabling them to support more services and users with lower power consumption .

Featuring multi-mode ZTP on-demand network orchestration; real-time fault alarms and 45+ visualized reports. The next-generation NetEngine AR routers support zero-touch provisioning (ZTP), which simplifies the network deployment and management process by automatically discovering, registering, configuring, and upgrading devices . They also support real-time fault alarms and 45+ visualized reports that provide comprehensive network monitoring and analysis capabilities .

Huawei AirEngine 6760 series supports four spatial streams by default, but after an RTU (Right To Use) license is purchased, it can support up to eight spatial streams on the 5 GHz band. It can also support four spatial streams on the 2.4 GHz band or scanning mode. Therefore, the possible spatial stream combinations are 4+8, 4+8+4, 4+4+scanning, and 4+6+scanning.

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.
