Which of the following best describes the purpose of a quota?

• A. It secures data using encryption
• B. It prevents overuse by limiting space for users or directories
• C. It mirrors data to another site
• D. It audits access to files

Answer: (B)

Quotas limit how much storage a user or directory can consume, which helps prevent overuse of space and keeps storage available for others. By setting soft and hard limits, you can allow some warning room or enforce a strict cap, so no single user or directory can exhaust the pool. Encryption, mirroring, and auditing serve other purposes—protecting data, replicating it for disaster recovery, and tracking access, respectively.
