The correct answer is C. 16. Explanation/Reference: Note: (vCPUs per VM x VMs per Host) / Overcommit (2 x 40) / 8 = 10 80 vCPU/8 = 10 pCPU. You can also get there with the Rule of 5 and 10. So 40 VMs/5 = 8 pCPU. So 8- 10 pCPU should allow plenty for performance hits since we would choose 16 cores. Also…

Question

Scenario: A Citrix Architect needs to design a new XenApp and XenDesktop environment. The table in the Exhibit lists details about the requirements of the current user groups and their Virtual Delivery Agent (VDA) machine workloads. Click the Exhibit button to view the table. The architect should scale the hardware used to host the VMs for User Group 1 to ______ cores. (Choose the correct option to complete the sentence.)

Explanation

Explanation/Reference: Note: (vCPUs per VM x VMs per Host) / Overcommit (2 x 40) / 8 = 10 80 vCPU/8 = 10 pCPU. You can also get there with the Rule of 5 and 10. So 40 VMs/5 = 8 pCPU. So 8- 10 pCPU should allow plenty for performance hits since we would choose 16 cores. Also, 8:1 is a high number. I like 6:1 better. But they are trying to turn it into a math problem, so you basically go for close without going over. 8/10/13... all would.be good on hardware with 16 cores. https://matthewmccarron.wordpress.com/ Let's say you just bought some new blades from Cisco and they're equipped with dual sockets and 16 cores each (i.e. 2×16). You're about to embark on your XenDesktop project and you're wondering how many VDIs each blade can support. Well, 160 VMs, of course! All I did there was multiply the number of physical cores in the box (32) by the magical XenDesktop multiplier (5).
