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

Huawei'sWAN ISP solutionis designed for Internet Service Providers (ISPs) with the following key highlights:

A. 99% satisfaction of customer requirements: Huawei emphasizes its end-to-end solution capability and customer satisfaction, making the solution highly competitive and marketable.

B. BNG/CGN/SR/IPsec 4-in-1 design: This integration minimizes device deployment and simplifies O&M.

C. Compact design (1U/2U): Ideal for small PoPs (Points of Presence), improves space efficiency.

D. Energy-saving: Huawei routers adopt energy-saving technologies, helping reduceenergy consumption by up to 30%.

These features are documented in Huawei'sISP WAN Solution brochureand emphasized in HCSA-IP training.

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.

Thefive-layer TCP/IP modelconsists of the following layers:

Application layer

Transport layer

Network layer

Data link layer

Physical layer

A. Application layer– Handles application-level protocols (e.g., HTTP, FTP).

B. Network layer– Handles logical addressing and routing (e.g., IP).

D. Transport layer– Manages end-to-end connections and reliability (e.g., TCP, UDP).

C. Radio layeris not part of the standard TCP/IP model — it's relevant in wireless physical-layer communication, butnot defined in the TCP/IP layering structure.
