Question 1
IntermediateDescribe different data protection technologies · Explain 3-2-1 as a data retention strategy
A healthcare provider is redesigning its data protection strategy to comply with strict HIPAA regulations. The architect recommends implementing a 3-2-1-1-0 backup rule instead of the traditional 3-2-1 rule to mitigate modern ransomware threats.
Which specific data protection concept is introduced by the first '1' in the 3-2-1-1-0 strategy?
Answer and explanation
Correct answer: C
While the traditional 3-2-1 rule dictates 3 copies of data, across 2 different media types, with 1 copy offsite, modern ransomware threats require additional safeguards. The 3-2-1-1-0 rule adds a requirement for 1 copy to be offline, air-gapped, or immutable (meaning it cannot be altered or deleted, even by an administrator, for a set period). The '0' represents zero errors during backup recovery verification.
