Which of the following descriptions about storage disaster recovery service SDRS is correct? (Multiple choice)

Question

Options

• ADisaster recovery is mainly aimed at major natural disasters such as fire and earthquake, so a
• BSupport GPU acceleration, FPGA acceleration, bare metal servers, and use storage disaster
• CThe disaster recovery system not only protects data, but also ensures business continuity
• DThe highest level of disaster recovery can achieve RPO=0, backup can set multiple automatic

• A
  75% (21)
• B
  25% (7)

Explanation

Options A, C, and D are correct because SDRS is designed primarily to protect against major disasters such as fires and earthquakes (A), it safeguards both data integrity and ongoing business operations rather than data alone (C), and at its highest protection tier it can achieve RPO=0 through synchronous replication while also supporting multiple automated backup schedules (D).

Option B is incorrect because SDRS does not support GPU acceleration, FPGA acceleration, or bare metal servers; these are specialized compute resources tied to other cloud services, and SDRS operates with standard Elastic Cloud Server instances for replication and failover.

Memory tip: Group the three correct answers by purpose - A covers the scope of threats (natural disasters), C covers the scope of protection (data plus continuity), and D covers the performance ceiling (RPO=0). B is the trap because it confuses disaster recovery with compute acceleration, which are entirely separate service categories.
