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
Which of the following are the hardware characteristics of the S8700? (Select All that Apply)
Correct Answer:ABD
Overview of the S8700 Switch:
The S8700 series is part of Huawei's high-end campus core switches, designed for large- scale enterprise networks. It offers advanced hardware features to meet demanding requirements.
Analysis of Each Option:

Which of the following statements are true?
Correct Answer:BC
Let us analyze each statement in detail:
The CloudEngine S5731-S supports VXLAN and can be used for VXLAN deployment across core and access layers : This statement is false . The CloudEngine S5731-S series does not support VXLAN. VXLAN capabilities are typically found in higher-end switches like the S5731-H or S6730-H series.
The CloudEngine S6730-H24X6C/S6730-H48X6C supports six 100GE ports, which can be auto-negotiated to 40GE ports : This statement is true . The S6730-H series switches support six 100GE ports that can be auto-negotiated to 40GE ports, providing flexibility for high-speed connectivity.
The CloudEngine S5731-H supports native AC and can be used as the core of a small- sized network : This statement is true . The S5731-H series supports native Access Controller (AC) functionality, enabling it to act as the core switch in small-sized networks while managing wireless APs.
The CloudEngine S8706 switch supports four independent service slots and two main control board slots with service ports : This statement is false . The S8706 switch supports six independent service slots and two main control board slots. The description provided in the statement is incorrect.
Thus, the correct answers are B and C . References:
