An operator needs to take a snapshot of a VM before an upgrade. The application team needs the ability to restore the VM with a consistent state of the guest file system while keeping the VM online. How can the operator accomplish this task?
A.
Right click VM > Migrate > Change Compute resource > Select Host > Finish
B.
Right click VM > Power > Power Off > Actions > Compatibility > Upgrade VM Compatibility > OK
C.
Power Off VM > right click VM > Snapshots > Take Snapshot > OK
D.
Right click VM > Snapshots > Take Snapshot > Choose option to quiesce guest file system > OK
D. The operator can accomplish this task by right-clicking the VM > Snapshots > Take Snapshot > Choosing the option to quiesce the guest file system > OK.
Quiescing a guest file system involves flushing any pending writes to disk and ensuring a consistent state of the file system.
By quiescing the guest file system before taking a snapshot, the application team can restore the virtual machine with a consistent state of the guest file system while keeping the virtual machine online.
This allows the operator to take a snapshot of the virtual machine and upgrade the virtual machine with minimal disruption to the application running on the virtual machine. The operator can simply revert to the snapshot if any issues arise after the upgrade.
