Which database service deployment option meets this requirement?

• A.two node bare metal system with data guard enabled
• B.two node real application cluster (RAC) system
• C.Autonomous Data Warehouse (ADW) system as it provides auto fail over functionality
• D.single node baremetal system

You had an outage in yourapplication caused by the loss of a shared volume provisioned by File Storage Service (FSS). At this point, you need to restore the data from a snapshot you created of the FSS.
What are the steps to restore the data?

• A.Open OCI Console, select File Storage Service, find the shared storage, then click onsnapshot and restore.
• B.Open OCI Console, select File Storage Service, find the snapshot you created and click restore.
• C.Access the directory, where you mounted the shared volume, then cd into .snapshot folder and find the snapshot folder you want to recover and rename that folder to the original folder name.
• D.Access the directory where the shared volume is mounted, then cd into .snapshot folder, find the snapshot folder you want to recover and use cp or rsync tool to copy the files to the original location.

You are designing a lab exercise for your team that has a large number of graphics with large filesizes. 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 publicand 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 by enabling read access to the bucket.
pre-authenticated requests have to select expiration date
