1Z0-1072-25 Question 257
Select 3You have created a new File Storage service file system in Oracle Cloud Infrastructure 2025. Multiple compute instances in the same private subnet should share this file system over NFS, but you find that the instances cannot mount the file system even though it was successfully created. Which three steps must you take to allow these instances to mount and use the file system?
- A
Create a mount target in the same VCN or a connected VCN reachable by your compute instances.
- B
Enable NFS v4.1 explicitly in the mount target configuration.
- C
Create an export for the file system with the correct export path and allowed subnets/IP addresses.
- D
Attach the file system as a block volume to each compute instance using iSCSI.
- E
Configure security lists or network security groups to allow NFS traffic on port 2049.
Show answer and explanation
Correct answers: A, C, E
Explanation
In Oracle Cloud Infrastructure, to configure File Storage for multiple compute instances, you must first create a file system and then establish a mount target to provide an NFS endpoint. An export is defined to specify where and how the file system can be mounted (e.g., export path, allowed subnets). Additionally, security lists or network security groups in your VCN must be configured to allow NFS traffic on port 2049. Refer to Oracle Cloud Infrastructure File Storage documentation for detailed instructions and best practices.
- A. Correct.
Option 1 is correct. A mount target is required to provide an NFS endpoint that compute instances can connect to. It must reside in the same VCN (or a peered/connected VCN) to be reachable by the instances.
- B. Incorrect.
Option 2 is incorrect. Oracle Cloud Infrastructure File Storage supports both NFS v3 and v4.1 by default without requiring an extra step to enable NFS v4.1 specifically in the mount target settings.
- C. Correct.
Option 3 is correct. You need to create an export for the file system specifying the export path (e.g., /myfiles) and the subnets or IP addresses that are allowed to mount it.
- D. Incorrect.
Option 4 is incorrect. File Storage is accessed via the NFS protocol, not attached as a block storage device. Attaching as a block volume applies to the Block Volume service, not File Storage.
- E. Correct.
Option 5 is correct. You must ensure that your security lists or network security groups permit inbound and outbound traffic on port 2049 for NFS, or mounting will fail.
