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
Correct Answer: B
Explanation/Reference:
Explanation:
An eager-zero disk allocates and zeroes out all the block at once. While this type of disk takes significantly longer to create, the disk performs better than the others because the other disks require the block to be zeroed out before writing to the block. Since the blocks have already been zeroed with eager-zero, that is not necessary.
