Three copies of data, on two different media types, with one copy offsite
Correct Answer: Three copies of data, on two different media types, with one copy offsite
The rule's whole point is surviving correlated failures: multiple copies defeat single-device loss, different media defeat media-class defects, and offsite defeats site disasters. / नियम का उद्देश्य सहसंबद्ध विफलताओं से बचना है: कई प्रतियाँ, भिन्न माध्यम, और एक ऑफसाइट प्रति। Option (a) is the trap — it invents an unrelated "3-2-1" about staffing.
