You have created a virtual cloud network (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 have read-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 file storage service.

You have multiple applications installed on a compute instance and these applications generate a large amount of log files. These log files must reside on the boot volume for a minimum of 15 days and must be retained for at least 60 days. The 60-day retention requirement is causing an issue with available disk space. What are the two recommended methods to provide additional boot volume space for this compute instance? (Choose two.)

A. Terminate the instance while preserving the boot volume. Create a new instance from the boot volume and select a DenseIO shape to take advantage of local NVMe storage.

B. Create an object storage bucket and use a script that runs daily to move log files older than 15 days to the bucket.

C. Create and attach a block volume to the compute instance and copy the log files.

D. Create a custom image and launch a new compute instance with a larger boot volume size.

E. Write a custom script to remove the log files on a daily basis and free up the space on the boot volume.

Which statement is true about cloning a volume?

A. You need to detach a volume before cloning from it.

B. A cloned volume is the same as a snapshot that has a dependency on the source volume.

C. You can change the block volume size when cloning a volume.

D. You can create a clone for a volume across regions.

You are about to deploy an e-business application on Oracle Cloud Infrastructure and one of the

requirements is to use a shared file system that supports the NFS protocol.

Which storage service would meet this requirement?

A. object storage

B. block volume

C. data transfer appliance

D. file storage

As the Cloud Architect for your company, you have been tasked with designing a high performance (HPC)

cluster in Oracle Cloud Infrastructure (OCI). The following requirements have been defined:

The cluster must be a minimum of three nodes, but may increase to six nodes when demand requires.

The cluster must be resilient to any potential infrastructure failures. To minimize latency, all nodes must be

deployed within the same availability domain (AD). Adding or replacing nodes within the cluster should

take no more than 30 minutes. Which two steps should be performed to satisfy these requirements in OCI? (Choose two.)

A. Deploy the cluster in a single AD with a shared file system that leverages the file storage service (FSS). Deploy a standby cluster in another AD and configure it to use the same shared file system.

B. Deploy the cluster in a single AD. Place each of the nodes in one of the three different fault domains in that AD.

C. Create a backup of your HPC node compute instance boot volume. Launch new compute instances directly from the backup reduce provisioning time.

D. Create a custom image of your HPC node compute instance. Launch new compute instances using this image to reduce provisioning time.

E. Deploy the cluster in a single AD. Place each of the nodes in a different virtual cloud network (VCN) subnet.
