An administrator was asked to enable deduplication and compression in the existing vSAN cluster. Which action must be taken prior to that action?
The correct answer is A. Ensure there is enough space to perform disk re-formatting operation. Before enabling deduplication and compression in a vSAN cluster, the operation requires reformatting all disk groups to apply the new data services. During this process, vSAN needs temporary space to migrate and protect existing data while the disks are being reformatted…

Explanation
Before enabling deduplication and compression in a vSAN cluster, the operation requires reformatting all disk groups to apply the new data services. During this process, vSAN needs temporary space to migrate and protect existing data while the disks are being reformatted. Therefore, it is critical to verify that sufficient free capacity (at least 30% recommended) is available in the cluster before enabling deduplication and compression to prevent data loss or reformat failure.
