1Z0-1072-25 Question 258
Select 2Your organization needs to share a single File Storage file system across multiple compute instances in different subnets within the same VCN. Which two steps are required to ensure secure and successful mounting of this file system from all subnets?
- A
- Configure an export for each subnet� CIDR block, specifying appropriate access permissions for each.
- B
- Update the security rules for the mount target� subnet to allow NFS traffic from each instance� subnet.
- C
- Create a separate mount target for each subnet in the file system� region.
- D
- Enable SMB protocol on the file system to mount it from any Windows or Linux instance.
Show answer and explanation
Correct answers: A, B
Explanation
When implementing File Storage in Oracle Cloud Infrastructure, you typically create a single mount target in a subnet that can be reached by other subnets with proper routing. You then configure export rules to control access from each subnet� CIDR block, and ensure security lists or network security groups permit NFS traffic on the required ports. Refer to the OCI File Storage documentation for details on configuring exports and network security to enable multi-subnet access.
- A. Correct.
- Correct. You must define export rules for each subnet� CIDR block (or IP address range) that needs access. These export rules specify read/write permissions, security settings, and ensure only authorized subnets can mount the file system.
- B. Correct.
- Correct. In addition to configuring exports, you need to allow NFS-related traffic in your network security configuration. This includes opening the required ports for NFS (for example, port 2049) in the security list or network security group assigned to the mount target� subnet, ensuring traffic can flow from each instance� subnet.
- C. Incorrect.
- Incorrect. You don�t need a dedicated mount target for each subnet if they are reachable within the same VCN. A single mount target can serve multiple subnets, provided routing, security rules, and exports are configured correctly.
- D. Incorrect.
- Incorrect. OCI File Storage uses NFS protocol. SMB mounting is not supported for File Storage, so enabling SMB protocol wouldn�t allow instances to mount the file system.
