Which type of virtual disk takes the longest to create but performs the best?

A.
Thin provisioned

B.
Eager-zero

C.
Lazy-zero

D.
Flat

Explanation:

An eager-zero disk allocates and zeros out all the block at once. While this type of disk
takessignificantly longer to create, the disk performs better than the others because the other
disks require the blockto be zeroed out before writing to the block. Since the blocks have already
been zeroed with eager-zero, that isnot necessary.
