Question
An administrator deploys a normal (non-stretched) cluster of six i3en.metal hosts in VMware Cloud on AWS. When deploying virtual machines to this cluster, which two of the listed storage policies would satisfy the service-level agreement (SLA) for a six host cluster? (Choose two.)
Options
- AFailure to tolerate = 1 failure -RAID-1 (mirroring)
- BSite disaster tolerance = Dual Site Mirroring
- CFailure to tolerate = 1 failure -RAID-5 (erasure coding)
- DFailure to tolerate = 2 failures -RAID-6 (erasure coding)
- EMC Workload Storage Policy -<cluster name>

Explanation
Clusters containing three to five hosts use 1 failure - RAID-1 (Mirroring). Clusters containing six or more hosts use 2 failures - RAID-6 (Erasure Coding). The VMC Workload Storage Policy -<cluster name> will be changed from 1 failure to 2 failures if the number of hosts change to 6 or more.
