What is the maximum packet loss rate allowed by A-FEC while ensuring smooth video playback in Huawei's SD-WAN solution?

Correct Answer:A
Understanding A-FEC (Adaptive Forward Error Correction):
A-FEC is a technology used in Huawei's SD-WAN solution to ensure smooth video playback even in the presence of packet loss. It adds redundant data to compensate for lost packets.
Maximum Packet Loss Rate:
A-FEC can tolerate up to40% packet loss (0.4)while maintaining smooth video playback. This ensures high-quality video streaming even in challenging network conditions. Conclusion:The correct answer is Option A, as the maximum packet loss rate allowed by A- FEC is 0.4.

What are the basic roles of devices in the typical MPLS VPN technical architecture? (Select All that Apply)

Correct Answer:ACE
MPLS VPN Architecture Overview:
MPLS (Multiprotocol Label Switching) VPN is a widely used technology for creating virtual private networks over a shared infrastructure. It involves specific roles for devices in the network.
Explanation of Each Role:
PE (Provider Edge):These devices sit at the edge of the service provider's network and connect to customer sites. They are responsible for assigning labels and managing VPN routes.
P (Provider):These devices are located in the core of the service provider's network.They perform label switching but do not participate in VPN-specific functions.
CE (Customer Edge):These devices belong to the customer and connect to the PE devices. They are unaware of the MPLS network and simply forward traffic to the PE. Aggregation and Core:These terms are not specific to MPLS VPN architecture. "Aggregation" refers to a general networking concept, and "Core" is too broad to describe a specific role in MPLS VPNs.
Conclusion:The correct roles in MPLS VPN architecture are PE, P, and CE. 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?

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.

By default, the USG6000E-B supports hardware bypass. If hardware bypass is required, you do not need to purchase an external bypass device.

Correct Answer:B
TheUSG6000E-Bfirewall doesnotsupport hardware bypass by default. If hardware bypass functionality is required, anexternal bypass devicemust be purchased and configured.Hardware bypass ensures network continuity in case of a firewall failure by physically rerouting traffic around the device. Since this feature is not included by default in the USG6000E-B, additional hardware is necessary to achieve it.

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?

Correct Answer:ABCD
Large and midsize campus networks face unique challenges due to their scale, diversity of devices, and evolving service demands. Below is an analysis of each option:
Unknown threats must be detected and contained to prevent intrusion and spread :
Security is a top priority in campus networks. Advanced threat detection mechanisms, such as AI-driven analytics and sandboxing, are essential to identify and mitigate unknown threats before they impact the network.
Diversified access terminals and services are calling for a converged network : Modern campus networks must accommodate a wide range of devices (e.g., smartphones, IoT devices, laptops) and services (e.g., voice, video, data). A converged network architecture simplifies management and ensures seamless connectivity across all devices.
As applications and services surge, the network needs to be automated to address the deployment and policy complexity : Automation tools, such as SDN and intent-driven networking (IDN), help streamline network deployment and policy enforcement, reducing manual intervention and minimizing errors.
Network O&M needs to be automated and intelligent to perceive user experience anytime and anywhere : Intelligent O&M solutions leverage AI and machine learning to monitor network performance, predict issues, and optimize user experience in real time.
All four options accurately describe the service requirements of large and midsize campus networks.
