A customer is deploying a new cluster and wants to be able to patch and update two hosts in parallel. The cluster must be able to maintain N+1 resiliency across the remaining hosts while patching activities are performed. The current expected utilization of the platform requires a minimum of two hosts to support all of the virtual machines.
What is the minimum number of hosts the customer will require in the cluster in order to meet the required resiliency level?
To maintain N+1 resiliency, the cluster must have enough hosts to support the workload even if one host fails. Given that a minimum of two hosts are needed to support the virtual machines, we need one additional host for resiliency, making it three hosts required during normal operation. Since the customer wants to patch and update two hosts in parallel without losing resiliency, an additional two hosts are needed for those updates. Therefore, the minimum number of hosts required is five (three for workload and resiliency, plus two for maintenance).
A. Five cluster must be able to maintain N+1 current expected utilization of the platform requires a minimum of two hosts to support all of the virtual machines. So, we need 3 hosts to support N+1. Customer wants to be able to patch and update two hosts in parallel. So that means 5 hosts are required.
i think is A
agree. Need N+1
Answer is A (N) 2 for workload+ 1 for resilience = 3 2 for maintenance so Total = 5
- (3) N+1 resiliency across the remaining hosts while patching activities are performed [minimum of two hosts to support all of the virtual machine] - (2) patch and update two hosts in parallel TOTAL 5
How about C : four We just need 3 hosts for support N+1 We can update and patch for 2 hosts in parallel in one time, and then update and patch for other 2 hosts ! So four is OK !
I change my answer to A ,when you patch ,you also need keep N+1
I think A. Five Focus: "update two hosts in parallel"
A. Five ;)
We need 5 hosts : once 2 hosts are in maintenance, we need to have 2 hosts left for the VMs, and 1 for resiliency. 2+2+1 = 5
