H12-891_V1.0 Exam Dumps : HCIE-Datacom V1.0

Huawei’sSD-WAN solutionoffers a full suite of application optimization technologies, including:

Application identification: Uses DPI and traffic signatures to identify applications.

Intelligent traffic steering: Dynamically routes traffic based on application type and real-time link performance.

WAN optimization: Reduces latency, deduplicates traffic, and optimizes throughput for key apps.

QoS: Prioritizes critical applications and ensures bandwidth guarantees.

All listed options are part of the Huawei SD-WAN solutionfor optimizing user experience and application performance.

Correct answers: A, B, C, D

Comprehensive and Detailed In-Depth Explanation:

In theCloudCampus public cloud scenario, when devices are deployed through theHuawei registration query center, there isno need to configure DHCP Option 148on the campus network’s DHCP server.

Theregistration query centerautomatically provides thecontroller IP addressto the devices during the registration process.

DHCP Option 148is typically used to provide theiMaster NCE-Campus addressin on-premises or private cloud scenarios.

In thepublic cloud scenario, the devices obtain this information directly from the Huawei cloud platform, makingOption 148 unnecessary.

Virtual Networks in Huawei CloudCampus Solution:

Virtual networks (VNs) aresegmented based on services(e.g., IoT, Guest Wi-Fi, Enterprise Wi-Fi).

Each VN has its ownrouting and forwarding instance(VRF).

Isolation Between Virtual Networks:

By default,different virtual networks are isolated.

If inter-VN communication is required, it must be manually configuredusingpolicy-based routing (PBR), inter-VRF routing, or firewall policies.
