In Huawei's SD-WAN solution, overlay topologies can be planned based on services. Different service topologies are independent of each other.
Correct Answer:A
Understanding Overlay Topologies in SD-WAN:
In Huawei's SD-WAN solution, overlay networks are created on top of the physical underlay network. These overlays can be customized based on specific services or applications.
Service Independence:
Different service topologies (e.g., voice, video, data) areindependent of each other, allowing granular control over traffic paths, QoS policies, and security settings. Conclusion:The statement is TRUE because overlay topologies in Huawei's SD-WAN solution are service-specific and operate independently.

Which of the following campus network challenges are enterprises facing as they move towards the all-cloud era?
Correct Answer:ABCDE
As enterprises transition to cloud-centric architectures, campus networks face several challenges:
Slow fault locating:Traditional networks lack intelligent tools for rapid fault detection and resolution, leading to prolonged downtime.
Wi-Fi discontinuous networking:Poorly designed wireless networks result in coverage gaps and inconsistent user experiences.
Cloud outpacing network:Cloud services evolve faster than traditional networks can adapt, creating bottlenecks.
Difficult network scaling:Legacy networks struggle to scale dynamically to meet growing demands.
Cross-domain fragile infrastructure:Fragmented management across domains (e.g., wired, wireless, WAN) leads to inefficiencies and vulnerabilities.
Addressing these challenges requires modern solutions like SDN (Software-Defined Networking), AI-driven O&M, and unified management platforms.

DCs can be classified based on the number of standard racks. Which type is a DC with 3000-10000 racks classified to?
Correct Answer:A
Classification of Data Centers (DCs):
Data centers are classified into categories such as small, midsize, large, and ultra-large based on the number of standard racks they house.
Rack Classification Criteria: Small DC:Less than 500 racks. Midsize DC:500-1000 racks. Large DC:1000-3000 racks.
Ultra-large DC:3000-10000 racks.
Conclusion:A data center with 3000-10000 racks falls under theultra-large DCcategory. References:
