   A media scan on an E-Series array detects a block with a Data Assurance (DA) checksum mismatch. According to the media scan process, what is the next step the controller takes?

   • AIt sends an alert to the host and waits for the administrator to initiate a rebuild.
   • BIt copies the block to a spare area and continues the scan without rewriting the original.
   • CIt marks the block as bad and removes it from the volume, logging an error.
   • DIt immediately rewrites the block with corrected data from the RAID parity or mirror.

   • BThe 'Hardware' tab to check for disk errors.
   • CThe 'Performance' tab to see if the scan is consuming I/O.
   • DThe 'Media Scan' tab under the volume group's properties.

   An administrator is reviewing the media scan report and sees a large number of 'Corrected' errors on a specific disk. What is the most appropriate course of action?

   • ACheck the disk's overall health and consider replacing it if errors continue to increase.
   • BContinue to monitor the disk, as corrected errors are normal and require no action.

   • DReplace the disk immediately, as any corrected error indicates imminent failure.

   A company stores long-term archival data on an E-Series array. The data is written once and rarely read. The administrator is concerned about silent data corruption over time. What is the primary benefit of enabling media scan in this scenario?

   • AIt reduces the total cost of ownership by using less disk space.
   • BIt improves the write performance of the archival data.
   • CIt allows the array to use slower, cheaper disks for archival data.
   • DIt detects and repairs media errors that could corrupt the archived data.
