同じOracleCloud Infrastructure(OCI)仮想クラウドネットワーク(VCN)内の2つの異なるサブネットで実行されている2つのNFSクライアントがあります。同じファイルシステムに接続する2つのNFSクライアント用の共有ファイルシステムを作成しましたが、一方のクライアントが読み取りアクセス権を持ち、もう一方のクライアントが読み取り/書き込みアクセス権を持つように制限したいとします。この要件を満たすためにどのOCr機能を活用しますか?
正解:C
Explanation
Oracle Cloud Infrastructure File Storage service provides a durable, scalable, secure,enterprise-grade network file system. You can connect to a File Storage service file system from any bare metal, virtual machine, or container instance in your Virtual Cloud Network (VCN). You can also access a file system from outside the VCN using OracleCloud Infrastructure FastConnect and Internet Protocol security (IPSec) virtual private network (VPN).
EXPORT
Exports control how NFS clients access file systems when they connect to a mount target. File systems are exported (made available) through mounttargets. Each mount target maintains an export set which contains one or many exports. A file system must have at least one export in one mount target in order for instances to mount the file system. The information used by an export includes the file system OCID, mount target OCID, export set OCID, export path, and client export options. For more information, see Managing Mount Targets.
EXPORT SET
Collection of one or more exports that control what filesystems the mount target exports using NFSv3 protocol and how those file systems are found using the NFS mount protocol. Each mount target has an export set. Each file system associated with the mount target has at least one export in the export set.
EXPORT PATH
A path that is specified when an export is created. It uniquely identifies the file system within the mount target, letting you associate up to 100 file systems to a single mount target. This path is unrelated to any path within the file system itself, or the client mount point path.
EXPORT OPTIONS
NFS export options are a set of parameters within the export that specify the level of access granted to NFS clients when they connect to a mount target. An NFS export options entry within an export defines access for a single IP address or CIDR block range. For more information, see Working with NFS Export Options.
