Explanation:
For confidential documents requiring high availability and resilience against regional outages, Multi-Regional and Dual-Regional storage classes are ideal. Multi-Regional replicates data across multiple regions globally, offering the highest level of availability. Dual-Regional replicates data across two regions within a single geographic area, ensuring high availability within that region. Other options like Nearline, Standard, and Regional do not meet the high availability and resilience requirements due to their design and storage replication strategies.

To ensure the highest availability and resilience for confidential documents in Cloud Storage, especially in the event of a regional outage, which storage classes should your company consider?
A
Nearline: Best for infrequent access, not designed for high availability.
B
Standard: Balances performance and cost but lacks regional redundancy.
C
Multi-Regional: Replicates data across multiple global regions for maximum availability.
D
Dual-Regional: Replicates data across two regions within a single geographic area for high availability.
E
Regional: Stores data in a single region, not suitable for high availability.
