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.

Challenges in Campus Networks During the All-Cloud Era:

As enterprises transition to cloud-based architectures, campus networks face several challenges due to increased complexity, scalability demands, and integration with cloud services.

Explanation of Each Challenge:

Difficult network scaling:As businesses grow, scaling traditional campus networks to meet increasing demands becomes challenging without proper automation and flexibility.

Cloud outpacing network:The rapid adoption of cloud services often surpasses the ability of traditional networks to adapt, leading to performance bottlenecks.

Wi-Fi discontinuous networking:Ensuring seamless Wi-Fi coverage and connectivity across large campuses is a significant challenge, especially in environments with high user density.

Slow fault locating:Traditional networks lack advanced tools for real-time monitoring and troubleshooting, resulting in delays in identifying and resolving issues.

Cross-domain fragile infrastructure:Managing multiple domains (e.g., wired, wireless, and cloud) introduces complexity and increases the risk of failures if not properly integrated.

Conclusion:All the listed challenges are valid and commonly faced by enterprises moving toward the all-cloud era.

While Huawei'sUSG series firewallsinclude basicanti-DDoS capabilities, they are not designed to completely replace standaloneanti-DDoS products. Firewalls primarily focus on access control, threat prevention, and policy enforcement, whereas dedicated anti-DDoS solutions offer advanced features like large-scale traffic scrubbing, anomaly detection, and mitigation for massive DDoSattacks.For environments facing sophisticated or volumetric DDoS threats, standalone anti-DDoS appliances or cloud-based services are recommended to complement firewall capabilities.
