Which of the following services offers a shared file system in OCI?

The OCI File Storage Service is designed explicitly to provide a shared file system that multiple Oracle Cloud Infrastructure (OCI) instances can access simultaneously. This service supports file-based storage, which allows users to create file shares that can be mounted on various compute instances.

One of the primary benefits of the File Storage Service is that it uses the Network File System (NFS) protocol, making it easy to integrate with existing applications that rely on shared file systems. This capability is essential for workloads that require collaboration between multiple compute instances, enabling efficient access and management of shared data.

In contrast, OCI Block Volumes is designed for single-instance attachment and is used for more traditional block storage needs, such as databases or applications that require high performance, but it does not provide a shared file system. OCI Object Storage is tailored for unstructured data and is typically used for storing objects, such as backups or media files, and does not support a file system interface. Similarly, OCI Archive Storage is specifically for long-term storage and archiving, offering lower costs for infrequently accessed data but also lacks a shared file system capability.

Thus, the correct service that provides a shared file system in OCI is the File Storage Service, making it the best choice for scenarios that require simultaneous
