HPE7-A11: HPE Aruba Networking Certified Professional - Campus Access ArchitectDemo

A large multinational financial institution has engaged you to design a new full-stack wired and wireless network for its new 6-story regional office building. The bottom two floors of the facility will be retail space for a large banking branch. The upper floors will be carpeted corporate office space, with each floor measuring approximately 100,000 sq ft (9290 sq m). All data centers are offsite and are out of scope for this project. The customer is underserved by its existing L2-based network infrastructure and wants to apply modern best practices in the new design. The network must be fully resilient and fault-tolerant, with dynamic segmentation at the edge.

The retail space will provide public guest Wi-Fi access. Retail associates will use corporate tablets for customer service, and the retail floors will contain a mix of wired and wireless devices. Corporate users will primarily connect wirelessly, but several wired clients, printers, and hard VoIP phones will also be used.

The customer also plans to renovate the corporate office space to take advantage of 'smart office' technology. These enhancements will enable blue-dot wayfinding, presence analytics, and other location-based services.

The client has decided to manage two wiring closets as one stack totaling 10 switches, with a minimum transport speed of 25Gbps over OM4 MM fiber. They also want to minimize stacking-cabling cost.

Which switch series would most economically meet these requirements?
