PROMPT

Recall, from an earlier lesson that Resiliency of Object Storage is selected based on data protection and access you require. Choose “Cross Region” to store your data across three regions within a geography for highest availability and resiliency. Choose “Regional” to store your data across multiple data center facilities within a single geographic region for best availability and performance. Choose “Single Data Center” to store your data across multiple devices in a single data center for when data locality matters most.

Similarly, you select Storage Class (or tier) of your Object Storage based on how often you expect to read the stored data, and impacts its cost. For example Choose “Standard” for active workloads.

Provide two other possible values for the Storage Class, other than “Standard”.
