Which of the following campus network challenges are enterprises facing as they move towards the all-cloud era? (Select All that Apply)
Correct Answer:
ABCDE
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.

Which of the following statements is FALSE about Huawei AirEngine 5761-11W?
Correct Answer:
B
The Huawei AirEngine 5761-11W is a Wi-Fi 6 access point (AP) designed for enterprise networks. Let us analyze each statement:
It supports a device rate of 1.775 Gbps : This is true . The AirEngine 5761-11W supports a maximum device rate of 1.775 Gbps, making it suitable for high-speed wireless connectivity.
It has no USB port : This is false . The AirEngine 5761-11W does have a USB port, which can be used for IoT expansion or other purposes.
It has one GE uplink port and four GE electrical downlink ports : This is true . The device includes one Gigabit Ethernet (GE) uplink port and four GE electrical downlink ports for wired connections.
It supports the leader AP feature : This is true . The leader AP feature allows the device to act as a controller for other APs in small-scale deployments, simplifying network management.
Thus, the false statement is B . References:

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
Huawei'sSD-WAN solutionallows for the creation ofoverlay topologiestailored to specific services. These topologies are logically independent, meaning they can be customized and optimized for different types of traffic (e.g., voice, video, data) without interfering with one another.This independence ensures that each service topology can meet its unique requirements, such as latency, bandwidth, and security, while maintaining overall network efficiency.

As more and more enterprise DCNs step into the AI era, more and more spine switch port bandwidth upgrades to 400G from 100G and leaf switch port bandwidth upgrades to 25G from 10G. If the customer requires the 25G TOR switch, which Huawei model can we propose?
Correct Answer:
C
Huawei'sCloudEngine series switchesare designed to meet the evolving demands of modern data center networks (DCNs). For customers requiring25G Top-of-Rack (TOR) switches, theCE6881is the ideal choice.Key details about the models mentioned:
CE6820:A lower-end switch that does not support 25G ports. CE6870:Primarily supports 10G and 40G ports, not 25G.
CE6881:Specifically designed for 25G access and 100G uplinks, making it suitable for AI- era DCNs.
CE6863E:Focuses on high-density 100G/400G switching, not 25G TOR requirements. TheCE6881aligns perfectly with the need for 25G TOR switches, enabling higher bandwidth and scalability for AI and cloud workloads.
