220-1101 - Hardware and Network Troubleshooting - Section 5.3
Troubleshoot and diagnose problems with storage drives and RAID arrays in a given scenario.
Diagnose storage faults from symptoms such as read/write failures, slow performance, clicking or grinding noises, S.M.A.R.T. failures, and a degraded or failed RAID array, and recognise when data is recoverable versus lost. Distinguish a drive controller or cable fault from media failure, and verify with appropriate tools before deciding whether to rebuild the array or restore from backup.
