NetApp Certified Implementation Engineer – ONTAP v4 — Question 9

An engineer has a 100GB volume with the space guarantee set to volume and fractional reserve set to 100. The snapshot reserve is disabled. The volume contains two 20GB LUNs, and each LUN has the space guarantee enabled and is 50% full. The engineer creates a snapshot of the volume, and no data is written or modified after the snapshot is taken.
What is the available space in the volume?

Answer options

• A. 60GB
• B. 40 GB
• C. 20GB
• D. 80GB

Correct answer: C

Explanation

The available space in the volume is 20GB because the two LUNs occupy 20GB each, totaling 40GB used. With the snapshot reserve disabled and no changes made after the snapshot, the total usable space remains at the volume's original size minus the used space, resulting in 20GB free. The other options are incorrect as they do not accurately reflect the calculations based on the given conditions.
