In what situation is object storage access different than block volume access?

The choice regarding object storage allowing for sharing across multiple instances is correct because it highlights a key characteristic of object storage that differentiates it from block storage. Object storage is designed for scalability and ease of distribution, making it ideal for use cases where data needs to be accessible by multiple users or applications simultaneously. This feature is particularly useful in scenarios such as big data analytics, media storage, and backup solutions, where multiple compute instances may need to read from or write to the same data stored.

In contrast, block storage typically presents a single volume to one instance at a time, so it doesn’t naturally support concurrent access by multiple instances without implementing specific configurations or using shared file systems. This fundamental design choice reflects the different use cases that object storage and block storage are intended to support.

Additionally, the other options do not accurately represent the distinguishing characteristics of object storage versus block volume access. Object storage is not limited to temporary data; it is often used for persistent and long-term storage. While block volumes do require a private IP to connect to instances, object storage can be accessed over the internet or a private network without a dedicated IP. Finally, while block volumes can indeed have regional constraints, this characteristic does not fundamentally differentiate them from object storage, which also
