The secure snapshot technology of OceanStor Dorado SAN is based on HyperCDP. What is the maximum retention time of secure snapshots that this feature can support?

Question

Options

• A40 years
• B20 years
• C30 years
• D10 years

• A
  13% (4)
• B
  77% (24)
• C
  6% (2)
• D
  3% (1)

Explanation

Option B (20 years) is correct because Huawei's HyperCDP-based secure snapshot feature on OceanStor Dorado SAN is designed with a maximum retention period of 20 years, balancing long-term data protection needs with practical storage and management constraints.

• A (40 years) is incorrect - this figure is double the actual limit and likely a distractor designed to catch test-takers who think "more must be better."
• C (30 years) is incorrect - this is another plausible-sounding number that exceeds the actual supported maximum by a decade.
• D (10 years) is incorrect - while a common retention period in many enterprise backup policies, it falls short of what HyperCDP's secure snapshot feature actually supports.

Memory tip: Think of 20 = two decades - HyperCDP gives you "two full decades" of snapshot retention, which aligns with long-term compliance requirements (like financial or healthcare regulations) without going to an impractical extreme.
