An administrator places a 300 GB virtual machine named `Finance1` on a 2 TB datastore containing other virtual machines. After virtual machine placement, the datastore has 200 GB of free space. The accounting department takes a nightly snapshot of Finance1, then deletes the previous snapshot. The administrator is concerned about snapshots filling the datastore.
Which statement is true regarding snapshots?
Any snapshot on Finance1 has the potential to fill the datastore to capacity. This is because snapshots capture the state of a virtual machine at a certain point in time and any changes made are written to a delta file. As the virtual machine continues to run and data changes, the snapshot file can grow, and in the worst-case scenario, it may grow large enough to fill the datastore, especially if substantial changes occur frequently.
B is Correct
B is Correct
Is option A completely wrong in this case?
It is unlikely that a snapshot of a 300gb VM would grow beyond 200gb in 24 hours, but it is possible. This would involve changes to 2/3rds or more of the VM's data in that 24 hour period. Still, this is possible, so B is correct.
I have seen poorly designed database servers/queries that could generate that much data
