You have created a virtual cloudnetwork (VCN) with three private subnets. Two of the subnets contain application servers and the third subnet contains a DB System. The application requires a shared file system so you have provisioned one using the file storage service (FSS). You also created the corresponding mount target in one of the application subnets. The VCN security lists are properly configured so that both application servers and the DB System can access the file system. The security team determines that the DB System should haveread-only access to the file system.
What change would you make to satisfy this requirement?

• A.Create an NFS export option that allows READ_ONLY access where the source is the CIDR range of the DB System subnet.
• B.Connect via SSH to one of the application servers where the file system has been mounted. Use the Unix command chmod to change permissions on the file system directory, allowing the database user read only access.
• C.Modify the security list associated with the subnet where the mount target resides. Change the ingress rules corresponding to the DB System subnet to be stateless.
• D.Create an instance principal for the DB System. Write an Identity and Access Management (IAM) policy that allows the instance principal read-only access to the filestorage service.

You have deployed a compute instance (VM.Standard2.24) to run an Oracle database. With this set up, you run into some performance issues and want to leverage an OCI Dense IO shape (VM.DenseIO2.24), with which you get 25.6 TB local NVMe SSD. You do not want to lose the configuration changes you made to the instance. Which of the following TWO steps ARE NOT required to make this transition?

• A.Terminate the VM.Standard2.24 instance and do not preserve the boot volume
• B.Create a new instance using the VM.Dense102.24 shape using the preserved boot volume and move the Oracle Database data to NVMe disks
• C.Terminate the VM.Standard2.24 instance and preserve the boot volume
• D.Create a new instance using a VM.DenseIO2.24 shape using the preserved boot volume and move the Oracle Database data to block volumes
