Correct Answer: A
Question 17
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: A,B,C,D
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. References: * Huawei Campus Network Solution Overview, HCSA-Presales-IP Network Documentation.
Question 18
All mainstream switches in the industry support ECA (encrypted packet detection).
Correct Answer: B
Question 19
AR550C-2C6CE supports OSPF, BGP routing capabilities and MPLS functions.
Correct Answer: A
Question 20
Which of the following statements is FALSE about RR in Huawei's SD-WAN solution?
Correct Answer: A
* Understanding the Role of RR (Route Reflector): * In Huawei's SD-WAN solution, the Route Reflector (RR) plays a critical role in distributing routing information and ensuring efficient communication between CPEs (Customer Premises Equipment). * Analysis of Each Statement: * Option A:This is FALSE. The RR in Huawei's SD-WAN solution doesnot directly implement communicationbetween SD-WAN networks and legacy MPLS networks. Instead, it focuses on distributing VPN routes and tunnel information within the SD-WAN overlay network. Communication with legacy MPLS networks typically requires additional integration mechanisms. * Option B:This is correct. The RR can be deployed on a physical AR router or as a virtualized instance (AR1000V vCPE). * Option C:This is correct. The RR can be deployed independently or co-located witha CPE at a site, depending on the network design. * Option D:This is correct. The RR distributes VPN routes and tunnel information between CPEs based on predefined VPN topology policies. * Conclusion:The FALSE statement is Option A.
