   A financial services company is deploying a Dell Unity XT system for a new trading application. The application requires high availability and high write performance. The storage team has 12 drives available and needs to maximize usable capacity while ensuring the system can tolerate at least two drive failures without data loss. Which RAID configuration should they use?

   • ARAID 5 with all 12 drives in a single RAID group
   • BRAID 1 with six mirrored pairs
   • CRAID 10 with six drive pairs
   • DRAID 6 with all 12 drives in a single RAID group

   A company is using a Dell Unity XT system with thin provisioning enabled on a storage pool. The storage administrator notices that the pool's used capacity is approaching the physical capacity, and the system has started to generate warnings. The administrator needs to ensure that the pool does not run out of space, but there is no budget to add new drives immediately. Which action should the administrator take first?

   • AReview the pool's data reduction savings and identify volumes that can be migrated to another pool.
   • BDisable thin provisioning on the pool to prevent further over-allocation.
   • CEnable compression on the pool to reduce the size of data.
   • DEnable deduplication on the pool to eliminate duplicate data.

   What is the primary benefit of using thin provisioning in a Dell midrange storage environment?

   • AIt reduces the need for data deduplication.
   • BIt improves performance by allocating more cache to frequently accessed data.
   • CIt allows applications to see more capacity than is physically allocated, deferring actual disk usage until data is written.
   • DIt guarantees that all allocated capacity is always available for write operations.
