A large multinational financial institution has contracted you to design a new full-stack wired and wireless network for their new 6-story regional office building. The bottom two floors of this facility will be retail space for a large banking branch. The upper floors will be carpeted office space for corporate users, each floor being approximately 100.000 sq ft (9290 sqm). Data centers are all off site and will be out of scope for this project. The customer is underserved by its existing L2-based network Infrastructure and would like to take advantage of modern best practices in the new design. The network should be fully resilient and fault-tolerant, with dynamic segmentation at the edge.
The retail space will include public guest Wi-Fi access. Retail associates will have corporate tablets for customer service, and there will be a mix of wired and wireless devices throughout the retail floors. The corporate users will primarily use wireless for connectivity, but several wired clients, printers, and hard VoIP phones will be In use.
The customer is also planning on renovating the corporate office space in order to take advantage of "smart office' technology. These improvements will drive blue-dot wayfinding. presence analytics, and other location-based services.
The client has decided that more critical switch stacks supporting Contact Center resources will need to support greater than 600W of CL4 PoE and have redundant power supplies These stacks will have approximately six members.
What would be the most economical choice Aruba switch series to meet these requirements?

What would be needed to ensure proper licensing of the solution?
ACME Retail has 38 locations spread out across five US states and two provinces in Canada. They are looking to grow 20% over the next two years. They have a head office (HO) with a staff of 200 employees. The organization has eight regional managers and two VPs who work from home and on the road. Stores typically have 17 employees on average per location.
The two warehouses have a remote loading system and 20 employees each to load the trucks and fulfill the online orders. The warehouse has 40-foot ceilings and large metal racks to store inventory. The main warehouse is 240,000 sq ft (≈22,300 sqm), and the Canadian warehouse is 130,000 sq ft (≈12,100 sqm). Forklifts on the loading docks are equipped with wireless tablets onboard.
A typical store is about 60,000 sq ft (≈5,575 sqm), and smaller stores are planned at 25,000 sq ft (≈2,320 sqm). The locations need to expand wireless access to vendors who set up displays or interactive kiosks.
The current infrastructure was installed in 2015 using wireless N technology in a coverage model. Wiring is Cat5, and fiber connections are uncertain. Inventory is placed directly on the floor when delivered.
Inventory control is handled through Zebra barcode scanners, but poor coverage and signal issues have made monthly inventory counts difficult.
The organization has a small help desk for store support and PC support for the office. The company plans to move away from the current PBX system later this year. They want to cut costs, move services to the cloud, and achieve real-time inventory control for online order fulfillment.
The network has been wired over the last 10 years, but new systems are trending wireless. They want to provide wireless access for employees, guests, vendors, and contractors. The new IT director will start next week, and the CTO has prioritized this project.
Additional context:
Marketing wants to interact with customers and collect more data.
The IT support desk needs to reduce staff by half.
The HO has an MDF and two IDFs (floors 1 and 2).
WAN circuits exist for HO.
Each store has a local Ethernet handoff from the cable provider in the office.
Budget is a concern, but the solution must last 7+ years.
Based on best practices and customer requirements, what is the correct WLAN approach?
