The correct answer is D. The hardware failure will only impact the specific capacity disk, so the vSAN administrator will. Reduce the failure domain of a capacity device failure. A failure of a capacity device in a disk group for a cluster using "Compression only" will only impact that discrete storage device, whereas the same failure using DD&C would impact the entire disk group. This reduced…
Question
A single capacity disk fails within a vSAN 7.0 U1 cluster running with a "compression-only" configuration enabled. The vSAN administrator must recognize the platform impact that has occurred and take steps to correct it. Which action should the vSAN administrator take?
Options
- AThe hardware failure will impact the entire disk group, so the vSAN administrator will need to
- BThe hardware failure will stop the running workloads, so the vSAN administrator will need to
- CThe hardware failure will impact all disk groups within the ESXi host, so the vSAN
- DThe hardware failure will only impact the specific capacity disk, so the vSAN administrator will

Explanation
Reduce the failure domain of a capacity device failure. A failure of a capacity device in a disk group for a cluster using "Compression only" will only impact that discrete storage device, whereas the same failure using DD&C would impact the entire disk group. This reduced impact area of a device failure also reduces the amount of potential data that vSAN needs to rebuild upon a device failure. https://blogs.vmware.com/virtualblocks/2020/09/22/space-efficiency-using- the-new-compression-only-option-in-vsan-7-u1/
