Which method allows for the quickest recovery when a Nutanix cluster faces issues with VM integrity?

Using snapshots for VM recovery
Redundant system configurations
Scheduled backups for production VMs
Live migration techniques

The correct answer is: Using snapshots for VM recovery

Utilizing snapshots for VM recovery is the fastest method when addressing issues with VM integrity in a Nutanix cluster. Snapshots capture the state of a virtual machine at a specific moment in time, allowing for immediate restoration to that point if any corruption or failure occurs. This process is quick and efficient because it minimizes downtime and enables users to revert the VM to a known good configuration without the need to restore data from an external backup or go through a lengthy recovery process. In a Nutanix environment, snapshots can be taken frequently and on-demand, which adds flexibility and ensures that recovery points are close to the current state of the VM. This immediacy in recovering from a failure is unparalleled compared to other methods. Other methods, while useful for prevention or longer-term data integrity, do not offer the same rapid recovery capabilities. Redundant system configurations can help maintain availability but do not directly address VM integrity issues. Scheduled backups take longer to restore as they may involve copying larger amounts of data, and live migration techniques focus on transferring VMs rather than direct recovery from integrity problems.
