You have two NFS clientsrunning in two different subnets within the same Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN). You have created a shared file system for the two NFS clients who want to connect to the same file system, but you want to restrict one of the clients to have READ access while the other has READ/Write access. Which OCr feature would you leverage to meet this requirement?

• A.Use VCN security rules to control access for the NFS clients
• B.Use OCI Identity Access Management to control access for the NFS clients
• C.Use File Storage NFS Export Options to control access for the NFS clients
• D.Use NFS security to control access for the NES clients

You are running several Linux based operating systems in your on .premises environment that you want to import to OCI as custom images. You can launch your imported images as OCI compute Virtual machines.
Which two modes below can be usedto launch these imported Linux VMs?

• A.Native
• B.Mixed
• C.Paravirtualized
• D.Emulated

Correct Answer: C,D

Explanation
You can use the Console or API to import exported images from Object Storage. To import an image, you need read access to the Object Storage object containing the image.
during the Import you can select the Launch mode:
For custom images where the image format is .oci, Oracle Cloud Infrastructure selects the applicable launch mode based on the launch mode for the source image.
For custom images exported from Oracle Cloud Infrastructure where the image type is QCOW2, select Native Mode.
To import other custom images select Paravirtualized Mode or Emulated Mode. For more information, see Bring Your Own Image (BYOI).

You are responsible for creating and maintaining an enterprise application that consists of multiple storage volumes across multiple compute instances in Oracle Cloud Infrastructure (OCI).
The storage volumes include boot volumes and block volumes for your data storage. You need to create backups of these storage volumes in the most time-efficient manner.
How can you meet this requirement?

• A.Create clones of all boot volumes and block volumes one at a time.
• B.Create on-demand full backups of bootvolumes, and copy data in block volumes to Object Storage using OCI CLI.
• C.Create on-demand full backups of block volumes, and create custom images from the boot volumes.
• D.Group together multiple storage volumes in a volume group and create volume groupbackups.

You want an Oracle Cloud Infrastructure (OCI) compute instance in your compartment to make API calls to other services within OCI without storing credentials in a configuration file.
What do you need to do?

• A.Instances cannot access services outside their compartment
• B.By default, all VM instances are created with an instance principal. Reference this instance principal in your IAM policy statement
• C.Create a dynamic group with appropriate matching rules to include the instance, and reference this group in your IAM policy statement
• D.VM instances are treated as users. Create a user, assign the user to that VM instance, and reference the instance in your Identity and Access Management (IAM) policy statement
