Explanation
A mount target is an NFS endpoint that lives in a VCN subnet of your choice and provides network access for file systems. The mounttarget provides the IP address or DNS name that is used together with a unique export path to mount the file system. A single mount target can export many file systems. Typically, you create your first mount target and export when you create your first file system. The mount target maintains an export set which contains all of the exports for its associated file systems.
Limitations and Considerations
Eachavailability domain is limited to two mount targets by default. However, you can export up to 100 file systems through each mount target.
See Service Limits for a list of applicable limits and instructions for requesting a limit increase.
Each mount target requires three internal IP addresses in the subnet to function. Two of the IP addresses are used during mount target creation. The third IP address must remain available for the mount target to use for high availability failover.
The File Storage service doesn't "reserve" the third IP address required for high availability failover. Use care when designing your subnets and file systems to ensure that sufficient IP addresses remain available for your mount targets.

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).
