Answer: Multi-Regional, Dual-Regional

The storage classes that best meet the requirement of high availability and resilience even in case of a regional outage are **Multi-Regional** and **Dual-Regional**. These storage classes replicate data across multiple regions, ensuring that even if one region experiences an outage, the data remains accessible from another. Here’s a breakdown of the options: - **Standard**: Offers a balance of performance and cost, but does not provide regional redundancy. - **Regional**: Stores data in a single region and is not suitable for high availability requirements. - **Coldline**: Optimized for infrequent access and is not designed for high availability. - **Dual-Regional**: Replicates data across two regions within a single geographic area, providing high availability within that region. - **Multi-Regional**: Replicates data across multiple regions globally, providing the highest level of availability and resilience. Therefore, **Dual-Regional** or **Multi-Regional** storage classes are the most appropriate choices to meet the company’s requirements for highly available and resilient cloud storage.
