In Huawei??s SD-WAN solution, to reduce the impact of packet loss on user services, you are advised to enable Forward Error Correction (FEC) for all traffic.

1. A. TRUE
2. B. FALSE

Correct Answer: B
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. References:

To meet service requirements in different industries, the campus network architecture and technical applications are designed based on industry characteristics. Which of the following options are the service requirements of large and midsize campus networks?

1. A. Network O&M needs to be automated and intelligent to perceive user experience anytime and anywhere.
2. B. As applications and services surge, the network needs to be automated to address the deployment and policy complexity.
3. C. Unknown threats must be detected and contained to prevent intrusion and spread.
4. D. Diversified access terminals and services are calling for a converged network.

Correct Answer: ABCD
Large and midsize campus networks face unique challenges due to their scale and diversity. Key service requirements include:
Automated and intelligent O&M:Ensures real-time monitoring and optimization of user experience, reducing manual intervention.
Automation for deployment and policy management:Simplifies the handling of complex configurations and policies as applications grow.
Threat detection and containment:Protects against unknown threats using AI-driven security solutions.
Converged networks:Supports diverse access terminals (e.g., IoT devices, smartphones) and services through unified infrastructure.
These requirements drive the adoption of modern technologies like SDN, AI, and network virtualization.
