Question 13

Which of the following statements are TRUE aboutiMaster NCEin terms of management and control?

Correct Answer:AC
iMaster NCE (Huawei??s Network Cloud Engine)is anintent-driven network management and control systemdesigned forSDN networks.
It supports both traditional and SDN-capable networks:
SNMPis used to manage and controltraditional (non-SDN) devices.
NETCONF + YANGis used to manageSDN-capable devicesin a structured and automated manner.
CLI is not a preferred method in SDN environmentsas it lacks automation and scalability. Reference:HCSA-Presales-IP Network Official Documentation – iMaster NCE Management Capabilities

Question 14

All Huawei NetEngine routers support IPsec, VXLAN, MACsec, and FlexE.

Correct Answer:B
Features Supported by Huawei NetEngine Routers:
Huawei NetEngine routers are designed for various use cases, including WAN, data center interconnect (DCI), and enterprise networking. However, not all models support every advanced feature.
Analysis of Features:
IPsec:Most NetEngine routers support IPsec for secure communication over public networks.
VXLAN:VXLAN support is limited to specific models optimized for data center or cloud environments.
MACsec:MACsec is supported only on certain high-end models for Layer 2 encryption. FlexE:FlexE is a feature available only on select high-end NetEngine routers designed for 5G transport and DCI.
Conclusion:The statement is FALSE because not all NetEngine routers support all four features (IPsec, VXLAN, MACsec, and FlexE).

Question 15

Huawei's vision for the datacom industry is "IP on everything".

Correct Answer:A
Huawei's vision for the datacom industry is indeed "IP on everything," reflecting its commitment to building ubiquitous, intelligent, and converged IP networks. This vision emphasizes the integration of IP technologies into all aspects of communication, including data centers, campuses, and wide-area networks, to support digital transformation and innovation.
The statement is therefore TRUE . References:

Question 16

Which of the following are factors affecting the wireless rate (throughput) of a Wi-Fi AP? (Select All that Apply)

Correct Answer:ABCD
Factors Affecting Wireless Rate:
The wireless rate (throughput) of a Wi-Fi AP depends on multiple factors, including hardware capabilities, environmental conditions, and configuration settings. Explanation of Each Factor:
CPU performance:The AP's CPU processes data packets and performs tasks like encryption/decryption. Higher CPU performance enables better throughput.
SNR (Signal-to-Noise Ratio):A higher SNR indicates a stronger signal relative to noise, resulting in better data rates.
Spatial stream:Wi-Fi 6 supports multiple spatial streams (MIMO), increasing throughput by transmitting multiple data streams simultaneously.
Frequency bandwidth:Wider channels (e.g., 20 MHz, 40 MHz, 80 MHz, or 160 MHz) allow higher data rates but may increase interference in crowded environments.
Conclusion:All four options are factors that affect the wireless rate of a Wi-Fi AP. References:

Question 17

Forwarding performance is an important metric for core routers. How much is the highest forwarding performance of Huawei core router NetEngine 40E X16A/X8A service processing unit?

Correct Answer:B
TheHuawei NetEngine 40E X16A/X8Ais ahigh-performance core routerused incarrier-grade networks.
Maximum forwarding performance: 2 Tbit/s per service processing unit. Supportshigh-density 100GE and 400GE interfaces.
Providesintelligent traffic scheduling, high reliability, and scalable architecture. Reference:HCSA-Presales-IP Network Official Study Guide, NetEngine 40E X16A/X8A Specifications

Question 18

What is the normal operating temperature of Huawei NetEngine 8000 M6 routers with DC power supply?

Correct Answer:B
The Huawei NetEngine 8000 M6 series routers are designed for robust performance in various environmental conditions. For models with DC power supply , the normal operating temperature range is -20??C to +65??C .
Below is an explanation of the other options:
0??C to +45??C : This range is too narrow and does not reflect the router's actual capabilities.
-40??C to +65??C : This range applies to extreme environments and is typically associated with AC-powered models or specialized variants.
-20??C to +45??C : This range is incorrect for DC-powered models, as the upper limit is lower than the actual specification.
Thus, the correct answer is B , as the operating temperature for DC-powered NetEngine 8000 M6 routers is -20??C to +65??C .
