Oracle Cloud Infrastructure (OCI) File Storage Service offers robust encryption capabilities to ensure data security. * B. Customer-Managed Encryption:Customers can choose to encrypt their data using their own keys stored in the OCI Vault service. This gives customers control over their encryption keys and enhances data security. * D. Oracle-Managed Encryption:By default, all data stored in OCI File Storage is encrypted using Oracle-managed keys. This ensures that data is encrypted at rest without requiring any action from the customer. Incorrect Statements: * A. Communication is not encrypted via HTTPSwhen accessing file systems; instead, encryption in transit is typically managed via NFS over TLS. * C. Encryption of communication to a mount target is handled via network configurations, not through export options. References: * Oracle Cloud Infrastructure Documentation:File Storage Encryption
