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

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 designing a lab exercise for your team that has a large number of graphics with large file sizes. The application becomes unresponsive if the graphics are embedded in the application. You have uploaded the graphics to Oracle Cloud Infrastructure and only added the URL in the application. You need to ensure these graphics are accessible without requiring any authentication for an extended period of time.
How can you achieve these requirements?

• A.Create pre-authenticated requests (PAR) and specify 00:00:0000 as the expiration time.
• B.Make the object storage bucket private and all objects public and use the URL found in the Object
  "Details".
• C.Make the object storage bucket public and use the URL found in the Object "Details".
• D.Create PARs and do not specify an expiration date.

Correct Answer: C

Explanation
Pre-authenticated requests provide a way to let you access a bucket or an object without having your own credentials. For example, you can create a request that lets you upload backups to a bucket without owning API keys.
When you create a bucket, the bucket is considered a private bucket and the access to the bucket and bucket contents requires authentication and authorization. However, Object Storage supports anonymous, unauthenticated access to a bucket. You make a bucket public by enabling read access to the bucket.
pre-authenticated requests have to select expiration date
