   What is the primary performance benefit of disk striping in a RAID configuration?

   • AIt allows multiple drives to be accessed in parallel, improving read and write throughput.
   • BIt increases storage capacity by compressing data before writing.
   • CIt reduces the number of drives needed by using parity to store data more efficiently.
   • DIt ensures data is written to the fastest drive in the array, minimizing latency.

   A company is deploying a new storage array for a file server that will store large files. The administrator must choose between RAID 5 and RAID 6. The array has ten drives. The administrator wants to maximize usable capacity while providing fault tolerance against at least one drive failure. Which RAID level should be selected?

   • ARAID 10
   • BRAID 6
   • CRAID 5
   • DRAID 0

   A company runs a mission-critical database that must be protected against both hardware failures and logical corruption. The database is stored on a storage array that supports snapshots and replication. The administrator needs to ensure that a logical corruption event can be rolled back quickly, while also protecting against a site failure. Which combination of techniques should the administrator implement?

   • ASynchronous replication only
   • BStorage virtualization and RAID 6
   • CFrequent snapshots and asynchronous replication to a remote site
   • DRAID 10 and snapshots

   An administrator is configuring a new RAID array for a database server that handles a high volume of small random writes. The database requires high availability and can tolerate the loss of only one drive. The administrator is considering RAID 5 and RAID 10. Which RAID level should be selected to best meet the performance and fault tolerance requirements?

   • ARAID 10
   • BRAID 0
   • CRAID 1
   • DRAID 5
