Exam 1Y0-402 topic 1 question 62 discussion

Scenario: A Citrix Architect is designing a new, 2,000-user XenApp and XenDesktop environment. The environment will use Windows Server 2016 for all Site infrastructure components (Delivery Controllers, StoreFront servers, Provisioning Services servers, Citrix Director). Provisioning Services (PVS) will be used to provision Virtual Delivery Agent (VDA) machines. The environment will include two primary use cases:
✑ Windows Server 2016 VDA machines providing hosted apps
✑ Windows 10 VDA machines providing random, non-persistent VDI
Within the company there is existing hardware which is hosting non-Citrix workloads. The hardware, which is using a third party hypervisor, has some spare capacity, but NOT enough to support the entire XenApp and XenDesktop environment. As a result, the IT team is planning to purchase additional hardware to support the expected capacity but has NOT determined which hypervisor will be used for that hardware. The IT team would like to utilize the existing hardware and wants to minimize the long-term costs of the solution while still providing a good user experience.
How should the architect design the hypervisor resource pools based on Citrix leading practice?
