EMC Proven Professional – XtremIO Specialist — Question 2

On an EMC Data Domain system, what is the role of file system cleaning?

Answer options

• A. Remove unreferenced segments from physical storage
• B. Delete data from VTL cartridges that have been marked as expired
• C. Remove all traces of a file to resolve classified message incidents
• D. Eliminate older snapshots if the file system exceeds 90% utilization

Correct answer: B

Explanation

The correct answer is B because file system cleaning specifically deals with deleting data from VTL cartridges that have been marked as expired. Option A is incorrect as it pertains to segment management rather than cleaning. Option C does not relate to the file system cleaning function in this context, and option D is not relevant since snapshot management is separate from the cleaning process.
