How do quotas work in ONTAP, and what is the difference between hard quotas and soft quotas?

• A. Hard quotas block usage when the limit is reached, while soft quotas provide alerts or warnings before blocking.
• B. Hard quotas and soft quotas both block usage immediately.
• C. Quotas only apply to the root volume.
• D. Quotas are used to encrypt data.

Answer: (A)

Quotas in ONTAP control how much space a specific namespace can use, such as a volume or a qtree. The key difference between the two modes is how strictly they enforce that limit. A hard quota blocks writes as soon as the limit is reached, enforcing the cap with no room for overages. A soft quota, by contrast, allows usage beyond a soft threshold for a defined grace period while issuing warnings, giving administrators time to intervene; if the grace period expires (or if a higher hard limit is set), enforcement kicks in. In short, soft quotas monitor and allow temporary overuse, while hard quotas enforce an exact cap. Quotas apply to volumes and qtrees, not just the root volume, and they don’t relate to encryption.
