Huawei H19-301_V4.0 - HCSA-Presales-IP Network V4.0

Huawei’sSD-WAN solutionprovides the following capabilities:

B. Intelligent traffic steering: Dynamically selects the best WAN link based on application SLA (e.g., latency, jitter).

C. Flexible overlay networking: Uses MPLS, Internet, and 4G/5G links in a hybrid WAN architecture.

D. Centralized management and WAN visualization: ThroughiMaster NCE, enabling centralized control and real-time monitoring.

A. Radio calibration on the Wi-Fiis a WLAN function andnot part of SD-WAN capabilities.

Huawei’sAR6700Vis avirtual router(vCPE) that supports deployment onmainstream public clouds, including:

Huawei Cloud

Microsoft Azure

AWS Cloud

However, as per the latest support matrix,Baidu Cloudisnot listed as a supported platformfor AR6700V deployment.

Huawei’s"1-3-5" troubleshooting model, powered byknowledge graphs and AI-driven analysis, enables:

1-minute fault detection

3-minute root cause analysis

5-minute fault resolution or demarcation

This mechanism is part of Huawei’siMaster NCE-based intelligent O&M system, ensuring24/7 online service,proactive monitoring, andover 90% fault identification accuracy within minutes.

Huawei’sHiSecEngine firewallshave achievedrecognition in the Gartner Magic Quadrant for Network Firewalls, butnot for 12 consecutive years. Huawei’s presence in this quadrant ismore recent, with consistent recognition over the past few years, particularly following the rebranding to HiSecEngine and performance improvements. The "12 consecutive years" claim is inaccurate per Gartner reports.

WheniMaster NCE (controller) and the analyzerare deployed on asingle node (combined deployment),certain advanced functions are limited or unavailabledue to resource constraints:

A. ERSPAN,C. MDC (Multi-Domain Control), andD. IFIT (In-situ Flow Information Telemetry)are still supported in basic or partial forms.

B. Multi-cloud simulationis aresource-intensive featurethat requiresindependent, dedicated controller and simulation nodesfor cloud interconnection emulation, and isnot supportedin combined deployments.

QoS (Quality of Service)is thetechnology used to prioritize and guarantee bandwidthand latency performance forVIP users and mission-critical applications. It enables:

Traffic classification and prioritization

Bandwidth guarantees and rate limiting

Low latency paths for real-time services

A. IPsec VPN– Provides secure tunneling, not traffic prioritization

B. SSH and C. SSL– Offerencryptionfor secure access, but not performance assurance

Huawei’s Data Center Network Solution, part of the CloudFabric architecture, highlights four core capabilities:

A. Ultra-stable reliability — Ensures 99.999% availability, delivering sustainable computing and fault-tolerant network infrastructure across various failure scenarios.

B. One network for diverse computing — Seamlessly supports diverse workloads (e.g., HPC, AI, traditional computing) with non-blocking fabric and intelligent forwarding, ensuring zero interruptions.

C. One map for intelligent O&M — Uses Huawei’s iMaster NCE to provide full-network visibility, proactive alarms, and AI-driven assurance, addressing O&M concerns.

D. One platform for simplified deployment — Enables centralized automation with zero-touch provisioning, minimizing configuration errors.

Huawei SecoManageris thecentralized management platformfor Huawei security devices, includinganti-DDoSappliances. It is used for:

Defense policy configuration

Dynamic scheduling of scrubbing resources

Device management

Report and log visualization for threat analysis

The other options serve different roles:

Qiankun-OP: Huawei's cloud-based SOC platform

HiSec Insight: Used for security situation awareness

DireHunter: Threat hunting and deep analysis tool

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.

Huawei SD-WAN providesflexible Internet access optionsbased on enterprise architecture and policies:

A. Centralized Internet access: Internet traffic from branches is sent to HQ or data center before being forwarded to the Internet

C. Local Internet access: Internet traffic is directly forwarded at the branch (also called DIA — Direct Internet Access)

D. Hybrid Internet access: Combines centralized and local Internet access based on application type or policy

B. Remote Internet accessisnot a standard Huawei-defined modein this context.
