Which of the following statements are TRUE about Huawei's audio and video service experience assurance? (Choose all that apply.)
Answer(s): A,D,E
Huawei uses beacon frames to dynamically manage network resources, including suppressing users generating heavy traffic to ensure a better quality of service for audio and video.Huawei's tests demonstrate that their solution significantly reduces delays in voice and video services during congestion scenarios, showcasing a performance improvement compared to industry averages.Heavy-traffic services are automatically suppressed to prioritize latency-sensitive audio and video services, ensuring a high-quality experience.
Which of the following Huawei AR models supports Wi-Fi and PoE power supply?
Answer(s): A
The Huawei AR651W-8P model supports both Wi-Fi and PoE (Power over Ethernet) power supply. This capability makes it suitable for scenarios where both wireless connectivity and powering connected devices through Ethernet are required. Other models like AR651, AR651W, and AR611W may have some of these features but not both Wi-Fi and PoE together.
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.
Answer(s): B
In Huawei's SD-WAN solution, Forward Error Correction (FEC) is recommended only for traffic that is sensitive to packet loss, such as voice and video traffic. Enabling FEC for all traffic can lead to unnecessary resource consumption and increased overhead, which may degrade network performance for non-critical traffic. It is better to selectively apply FEC where it is most beneficial.
Which of the following AR models supports SRv6?
Answer(s): C
The Huawei AR8140 model supports SRv6 (Segment Routing over IPv6). SRv6 is a modern network technology that simplifies network operations by enabling source routing directly in the IPv6 packet headers.This capability is typically found in high-performance and advanced router models like the AR8140.
What border security protection capabilities do AR routers provide? (Choose all that apply.)
Answer(s): A,B,C,D,E
Huawei AR routers provide comprehensive border security protection capabilities to ensure network safety.These include:Antivirus: Protects against malicious software by detecting and preventing virus infections.Application-level ACL: Enforces access control based on applications and improves security by applying rules at the application layer.Stateful inspection and packet filtering firewall: Monitors the state of active connections and filters traffic based on predefined security rules, providing robust protection.Remote URL filtering: Prevents access to malicious or inappropriate websites by filtering URLs in traffic.IPS (Intrusion Prevention System): Detects and mitigates threats by analyzing traffic for malicious activities,enhancing overall network defense.
