A VNX SnapSure snapshot has recently been created on a production file system (PFS). The
second block in the PFS will be modified for the second time.
How will SnapSure handle the bitmap value for this file system update?
A.
It remains unchanged; PFS is updated
B.
It is changed to 1; PFS is updated
C.
It remains unchanged; SavVol is updated
D.
It is changed to 1; SavVol is updated
correct answer is D, it will change the bitmap value for 1 and put the ‘old blcok data’ in savvol + add an entry in blockmap

“second block in the PFS will be modified for the second time…”
At the second time bitmap is not changed. New data is only written in the PFS.
