CompTIA Server+ SK0-005 Practice Question
A financial-services firm hosts its production SQL database on a single 2U rack server that contains eight 4 TB SAS drives. Because customer transactions occur 24 × 7, losing data or experiencing more than a few minutes of downtime is unacceptable. The security team has flagged hardware failure of a local disk as a major data-security risk. Which mitigation strategy most directly addresses this risk and allows the server to keep running if as many as two drives fail at the same time?
Enable full-disk AES-256 encryption on all server volumes.
Require multifactor authentication (MFA) for all administrator logins.
Schedule nightly incremental tape backups to an off-site library.
Configure the eight drives as a RAID 6 array and designate one global hot spare.
