The major difference between Huawei S5731-H and S5731-S switches in software features is the VXLAN function.
Correct Answer:
A
TheS5731-HandS5731-Sare part of Huawei's CloudEngine S series switches, but they differ in their software capabilities. Specifically:
S5731-H:Supports advanced features likeVXLAN (Virtual Extensible LAN), which enables network virtualization and scalable overlay networks.
S5731-S:Lacks VXLAN support, making it suitable for simpler deployments without virtualization requirements.
This distinction is critical when selecting switches for environments that require advanced virtualization and cloud integration.

Which of the following statements are TRUE about fixed ports and cards of AR routers? (Select All that Apply)
Correct Answer:
BCD
Overview of Fixed Ports and Cards in AR Routers:
AR routers have fixed ports and modular cards that support various networking functions, including Layer 2 and Layer 3 operations.
Analysis of Each Statement:
Option A:This is incorrect. Not all Layer 2 cards support LAN/WAN switching; it depends on the specific model and card type.
Option B:This is correct. Layer 2 cards with VLANIF interfaces can perform simple Layer 3 forwarding but lack advanced features like NAT, MPLS, IPsec, and HQoS.
Option C:This is correct. Some AR router models allow WAN ports to be reconfigured as LAN ports, providing flexibility in deployment.
Option D:This is correct. Theundo portswitchcommand can be used to switch LAN ports to WAN ports, enabling Layer 3 functionality.
Conclusion:The correct statements are Options B, C, and D. References:

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:

Among the core values of the hyper-converged data center network solution, which of the following improvements is the result of full-lifecycle automation?
Correct Answer:
B
Hyper-converged data center network solutions emphasize automation across the entire lifecycle, from deployment to operations. Below is an analysis of each option:
100% unleashing of computing power : While automation can optimize resource allocation, achieving 100% utilization of computing power is not directly tied to full-lifecycle automation.
TTM reduced by 90% : Full-lifecycle automation streamlines processes such as provisioning, configuration, and scaling, significantly reducing Time-to-Market (TTM). This is a direct benefit of automation.
Proactive prediction of 90% of faults : Proactive fault prediction is typically achieved through AI-driven analytics, not solely through automation.
Storage performance improved by 90% : Improvements in storage performance are more closely related to advancements in hardware (e.g., NVMe over Fabrics) and software optimizations, rather than automation.
Thus, the correct answer is B , as full-lifecycle automation primarily reduces TTM. References:
