WhileForward Error Correction (FEC)is a valuable feature in Huawei's SD-WAN solution for mitigating packet loss, it is not recommended to enable FEC forall traffic. FEC introduces additional overhead by transmitting redundant data, which can consume bandwidth and degrade performance for non-critical traffic.Instead, FEC should be selectively enabled for sensitive applications (e.g., real-time voice and video) where packet loss has a significant impact. This approach balances performance and resource utilization effectively.

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:

Option A:The S8700 supports ultra-high PoE++ output capability, enabling long-distance power delivery for devices such as Wi-Fi access points and IP cameras.

Option B:The main control boards in the S8700 operate in 1:1 backup mode, ensuring seamless failover without packet loss or performance degradation.

Option C:This statement is incorrect. Service subcards arenot integratedon the main control board panel; they are separate components that enhance flexibility.

Option D:The S8700 supports ultra-high-density cards with GE optical, GE electrical, and 10GE optical ports, providing versatile connectivity options.

Conclusion:The correct hardware characteristics are Options A, B, and D.

Overview of IoT Integration in Huawei APs:

Huawei IoT APs support various methods to integrate IoT modules or functions, enabling unified management of Wi-Fi and IoT devices.

Explanation of Each Method:

Built-in IoT chip:Some Huawei APs come with built-in IoT chips, providing native support for IoT protocols like Zigbee, Bluetooth, or RFID.

USB interface:External IoT modules can be connected via the USB interface, allowing flexible integration of additional IoT functionalities.

PCIe interface:High-speed IoT modules can be integrated using the PCIe interface, offering enhanced performance and scalability.

PoE out port:While PoE out ports provide power to external devices, they do not directly integrate IoT modules or functions.

Conclusion:The correct methods are Options A, B, and C.

Application-layer DDoS attacks target specific applications or services, such as HTTP floods or DNS amplification. Below is an analysis of each option:

AntiDDoS : This product is specifically designed to detect and mitigate DDoS attacks, including application-layer attacks. It provides real-time traffic analysis and automated mitigation capabilities.

FireHunter : This is a sandbox solution used for detecting advanced threats and malware. It is not designed to defend against DDoS attacks.

USG6000E : This is a next-generation firewall that provides basic DDoS protection but lacks the specialized capabilities of AntiDDoS for large-scale attacks.

HiSec Insight : This is a security analytics platform that provides visibility into threats and vulnerabilities. While it can help identify DDoS activity, it does not actively mitigate attacks.

Thus, the correct answer is A , as AntiDDoS is the best-suited product for defending against application-layer DDoS attacks.

MPLS (Multiprotocol Label Switching) uses labels to forward packets efficiently along predefined paths called Label Switched Paths (LSPs). These labels are assigned dynamically using protocols likeLabel Distribution Protocol (LDP)or RSVP-TE (Resource Reservation Protocol - Traffic Engineering).While static routing and manual configuration can define paths, they do not involve dynamic label assignment.Similarly, direct routes are not related to MPLS label distribution. LDP is specifically designed to exchange label information between routers, enabling MPLS forwarding.

Huawei'sAR routerssupport multiple deployment modes to simplify network setup and management:

USB-based deployment:Configuration files can be loaded via USB drives, enabling rapid deployment without manual intervention.

DCN deployment:Devices are automatically discovered and configured through Huawei's Device Control Network (DCN), streamlining large-scale deployments.

DHCP option-based deployment:Routers obtain configuration parameters from a DHCP server, reducing manual setup efforts.

Email-based deployment:Configuration files can be sent to devices via email, allowing remote provisioning.

These modes cater to different scenarios, ensuring flexibility and ease of deployment.

Hyper-Converged Data Center Network Solution:

Huawei's hyper-converged data center network solution emphasizes automation, intelligence, and efficiency across the entire lifecycle of network operations.

Impact of Full-Lifecycle Automation:

TTM (Time to Market):Full-lifecycle automation significantly reduces the time required to deploy and manage services, resulting in a90% reduction in TTM.

Proactive fault prediction:While automation enhances fault detection, proactive prediction of 90% of faults is primarily driven by AI and analytics, not just automation.

Storage performance:Improvements in storage performance are typically achieved through hardware optimization, not automation.

Unleashing computing power:This is related to resource utilization and orchestration, not directly to full-lifecycle automation.

Conclusion:The improvement attributed to full-lifecycle automation is Option A, as TTM is reduced by 90%.
