A systems administrator is tasked with deploying a new VI Workload Domain cluster to support the HR system. A new storage policy must be created to satisfy the following requirements:
• Support two host failures
• Use the least amount of hosts
• Minimize storage capacity usage
Which configuration will satisfy these requirements?
To meet the requirement of supporting two host failures while minimizing storage capacity usage and utilizing the least amount of hosts, a configuration of 6 hosts with FTT=2 and RAID 5/6 is optimal. RAID 5/6 (Erasure Coding) is more space-efficient compared to RAID 1, which would require more storage overhead. Although RAID 1 offers higher performance, it is not space-efficient. Therefore, using 6 hosts with RAID 5/6 achieves the balance of fault tolerance, minimized storage usage, and efficient host utilization.
because RAID-5/6 (Erasure Coding) uses less disk space, but the performance is reduced. and FTT2

This is so wrong. First off, this VCF, not VMC on AWS. Second, RAID1 is the failure protection method that most consumes space. Right answer is B.
I think correct answer is C because "Use the least amount of hosts" is a pre-requisites.
Yes but notice it says failures to tolerate = 2. C cannot be correct.
