Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

SAN provides multiple levels of redundancy throughout the entire data path: redundant switches, multiple paths (via multipathing), redundant controllers in storage arrays, RAID within the storage, and often replicated storage at different locations. NAS has some redundancy but not as comprehensive. DAS and JBOD have minimal redundancy as they're directly attached with single paths.
