H19-301_V4.0 Exam Dumps : HCSA-Presales-IP Network V4.0

VXLAN (Virtual Extensible LAN) technology uses MAC-in-UDP encapsulation to extend Layer 2 networks over Layer 3 networks.

It encapsulates the original Ethernet frame into a UDP packet, allowing it to traverse an IP network.

VXLAN decouples the logical network from the underlying physical network, meaning MAC addresses of VMs are encapsulated and do not affect the routing of packets across the IP underlay.

VXLAN supports large-scale network expansion with up to 16 million VXLAN segments (compared to 4096 VLANs).

Furthermore, because VXLAN uses a routed underlay network, VM migration is not restricted by Layer 2 boundaries.

In Huawei'sUSB-based SD-WAN deployment method, thecommon stepsinclude:

D. Plan sites and configure devices and the network: This is done first in the iMaster NCE system.

B. Generate a deployment file: After planning, the system generates the configuration file.

C. Perform onsite ZTP deployment: This file is copied to a USB drive and plugged into the device for ZTP.

A. Import initial configuration files in batchesis not part of USB-based deployment but applies tobulk deploymentmethods using the network or controller directly.

Huawei defines theWLAN network lifecycleusing acomprehensive four-stage model, which includes:

B. Plan: Network coverage, capacity, and performance planning

A. Construct: Deployment of APs, controllers, and configurations

C. Maintain: Ongoing network operation and fault handling

D. Optimize: Performance tuning, channel optimization, and roaming refinement

These stages are covered in theWLAN planning and deployment methodologyusing tools likeSCTandiMaster NCE-Campus.
