The hospital CIO is interested in reviewing the phase 1 approach and framework that will be used to achieve the goals of the network refresh project.

What is the phase 1 task?

'Don't Buy at Us' is a US-based retail company that is expanding Into Europe. They are expanding into EMEA with a regional headquarters called HQ2 inside The Netherlands.

Their US-based headquarters HQ1 was refreshed last year based on the Aruba ESP architecture. You have treated the design for HQ? based on the same design as HQ1. a two-tier architecture. The high level is shown below.

Switch BOM for this project based on Two Tier:

Collapsed Core: 2 x Aruba 8360-16Y2C in VSX (ISL 2» ICOG0E DAC)

Access Slack: 10 x Slack of Aruba 6200F 48G Class4 PoE 4SFP- 740W each stack has A members. VSF

with 10GbE VSF links) 12 x 10GbE uplink pet stack)

During the presentation of your design to the CTO of 'Don't Buy at Us' you were informed about the updated fiber infrastructure that Don't Buy at Us' has installed in HQ2.

The core stack is Installed in the MDF and per IOF there is one access stack installed. Based on best practice, what is the most cost-effective update to the switch BOM?

You are going with a 3-tier design and need to calculate the oversubscription ratio on the Access. Distribution. Core, and ToR Layer. What is a suitable oversubscription ratio for each layer?
