You are a network architect of an application running on Oracle Cloud Infrastructure (OCI). Your security team has informed you about a security patch that needs to be applied immediately to one of the backend web servers. What should you do to ensure that the OCI load balancer does not forward traffic to this backend server during maintenance?

• A.Drain all existing connections to this backend server and mark the backend web server offline
• B.Create another OCI load balancer for the backend web servers, which are active and handling traffic
• C.Edit the security list associated with the subnet to avoid traffic connectivity to this backend serve
• D.Stop the load balancer for maintenance and restart the load balancer after the maintenance is finished

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 used to 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 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 should 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.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.
• D.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.
