Server Storage Management: Disk Quotas and Deduplication
Short answer
BC Deduplication Disk quotas
Question
Key Takeaways
The exam tests the distinction between space control mechanisms (quotas) and data reduction technologies (deduplication vs. compression), with the trap being the confusion between reducing file size via compression versus eliminating duplicate blocks.
This question tests the ability to select storage management techniques that enforce data limits and reduce redundancy. The community consensus confirms that disk quotas and deduplication are the correct solutions for controlling share size and minimizing redundant data respectively.
Common mistake: Candidates often confuse Compression with Deduplication; while compression reduces file size, it does not eliminate redundant data across multiple files or shares like deduplication does.
Expert Analysis
Why the Answer Is Correct
Disk quotas (Option C) are the standard mechanism for enforcing policies on how much data a specific user or group can store, directly addressing the 'enforcement policies' requirement. Deduplication (Option B) identifies and removes duplicate copies of repeating data at the block level, which is the most effective method for minimizing redundant data on the server.
Why the Other Options Are Wrong
Partitioning (Option A) divides a drive into logical sections but does not manage usage limits or redundancy. Compression (Option D) shrinks individual file sizes but does not remove identical data blocks shared across different files or users. Cloning (Option E) creates exact copies of data, which would increase redundancy rather than minimize it.
Community Comment Notes
Comments [2] and [3] provide clear mappings between the question's keywords and the answers. Comment [3] specifically highlights the technical distinction that compression only trims file size, whereas deduplication targets redundant data structures, reinforcing why B is superior to D in this context.
Exam Strategy
When asked about 'reducing redundancy,' prioritize Deduplication over Compression. When asked about 'enforcing limits' or 'policies' on user/group storage, always choose Disk Quotas.

PaytoPlay 👍 2I would go with B & C. Compression only shrinks file sizes.

cj207800 👍 1Disk quotas allow the administrator to enforce policies on how much data each home share can hold. This feature enables setting limits on the amount of disk space that users or groups can use, which directly addresses the requirement to control data allocation for home shares Deduplication is a technique that minimizes redundant data on the server by identifying and eliminating duplicate copies of repeating data. This process significantly reduces storage consumption, meeting the requirement to minimize redundant data on the server.

Stache 👍 1"enforcement policies on how much each home share can hold" = (C) Disk quotas "the amount of data that is redundant on the server must be minimized" = (B) Deduplication *Compression would only trim the file size down not minimize the redundant data
