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 twosteps 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 thesame 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 thebackup 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.

You need to create a high performance shared file system, and have been advised to use file storage service (FSS). You have loggedinto the Oracle Cloud Infrastructure console, created a file system, and followed the steps to mount the shared file system on your Linux instance. However, you are still unable to access the shared file system from your Linux instance.
What is the likely reason for this?

• A.There are no security list rules for mount target traffic
• B.There is no internet gateway (IGW) set up for mount target traffic
• C.There is no Identity and Access Management (IAM) policies set up to allow you to access the mount target
• D.There is no route in your virtual cloud network's (VCN) route table for mount target traffic
