Which OCI feature can be used to manage multiple filesystems connected to NFS clients?

The feature that can be used to manage multiple filesystems connected to NFS clients is the Export Path. In Oracle Cloud Infrastructure (OCI), the Export Path is a specification provided when configuring NFS (Network File System) sharing, which defines the directories and filesystems that can be accessed over the NFS protocol from client machines.

By setting the Export Path, you can direct permissions and access rules specifically to different filesystems, ensuring that only the designated NFS clients can mount and interact with those filesystems. This allows for effective management of multiple filesystems by specifying which file systems are accessible by which clients, making it a crucial component in environments where multiple clients need to access different resources securely and efficiently.

In contrast, the other options have different purposes. Sharing Rules typically define policies regarding how resources are shared but are not specifically geared towards managing connections to multiple filesystems. Access Control Lists (ACLs) provide granular control over individual user permissions within a filesystem but do not facilitate the connection to NFS clients directly. Subscription Plans relate to the consumption of cloud resources and are not relevant to filesystem management in an NFS context. Hence, the Export Path stands out as the most pertinent feature for managing NFS connections to multiple filesystems.
