A systems administrator is managing a file server that hosts user home directories on a shared volume. To better manage storage resources, the IT department has mandated a new policy: users should be notified when their directory reaches 45 GB of space, but they must be prevented from writing any new data once their usage hits 50 GB. Which of the following actions will BEST meet these requirements?
Enable data deduplication on the volume.
Configure a soft quota at 45 GB and a hard quota at 50 GB.
Enable a single hard quota at 50 GB for the volume.
Implement file screening to block files larger than 1 GB.
The best solution is to configure a soft quota at 45 GB and a hard quota at 50 GB. A soft quota functions as a monitoring threshold: when the user's consumption reaches 45 GB it can trigger e-mail, event-log, or other notifications, yet it still permits additional writes. A hard quota is an absolute ceiling; once the 50 GB limit is hit, further write operations are denied, satisfying the requirement to stop additional data. A single hard quota set to 50 GB would enforce the upper limit but, by itself, would not provide an earlier 45 GB warning. File screening in FSRM blocks files based on file types (for example, *.mp3 or *.exe) and cannot enforce a total-size limit for a user. Data deduplication reduces physical disk usage but does not alter the logical space attributed to each user, so it fails to meet either requirement.
