Answer: Dual-Regional: Stores data across two specific regions, offering redundancy and high availability even during regional outages., Multi-Regional: Ensures data availability across multiple regions within a continent, suitable for high availability and resilience.

**Correct Options:** - **E. Dual-Regional:** This storage class is designed for scenarios requiring high availability and resilience by storing data across two specific regions. It meets compliance requirements through geo-redundancy and enhanced availability. - **C. Multi-Regional:** Ideal for applications needing high availability and resilience, this class stores data across multiple regions within a continent, ensuring data remains accessible even if an entire region becomes unavailable. **Incorrect Options:** - **A. Coldline:** While offering redundancy, this class is optimized for less frequently accessed data and does not meet the high availability needs during regional outages. - **B. Standard:** Lacks the resilience against regional outages, offering only high availability within a single region. - **D. Regional:** Similar to Standard, it provides high availability within a single region but fails to ensure resilience in the face of regional outages.
