You have a block volume created in the US West (Phoenix) region. You enabled Cross Region Replication for the volume and selected US West (San Jose) as the destination region. Now, you would like to create a new volume from the volume replica in the US West (San Jose) region.
What should you do?
The explanation is that when you enable Cross Region Replication for a block volume, Object Storage creates a replica of the volume in another region of your choice. The replica is not available as a block volume until you activate it. To activate a replica, you need to select the replica from the Block Storage console and click Activate Replica. This will create a new block volume from the replica in the destination region.
You plan to upload a large file (3 TiB) to Oracle Cloud Infrastructure (OCI) Object Storage. You would like to minimize the impact of network failures while uploading, and therefore you decide to use the multipart upload capability.
Which TWO statements are true about performing a multipart upload using the Multipart Upload API?
While a multipart upload is still active, you can keep adding parts as long as the total number is less than 10,000. When you split the object into individual parts, each part can be as large as 50 GiB. The explanation is that a multipart upload allows you to upload a large object in parts, which can improve performance and reliability. You need to split the object into parts yourself and upload each part separately using the Multipart Upload API. You can add parts to an active multipart upload until you reach the maximum number of 10,000 parts per upload. Each part can range from 10 MiB to 50 GiB in size, except for the last part, which can be any size.
You have objects stored in an OCI Object Storage bucket that you want to share with a partner company. You decide to use pre-authenticated requests to grant access to the objects. Which statement is true about preauthenticated requests?
You cannot edit a pre-authenticated request is a true statement about pre-authenticated requests. Pre-authenticated requests are URLs that allow users to access objects or buckets in OCI Object Storage without requiring additional authentication or authorization. Pre-authenticated requests can be created with an expiration date and time, and can be used for read or write operations. However, once created, pre-authenticated requests cannot be edited, but can only be deleted or extended. The other statements are false about pre-authenticated requests.

company sells services to photographers where patrons can preview the photos that they want prints for.
To avoid unauthorized copies, the sample photos have lower resolution and are watermarked. The photos are processed after they are uploaded. The process is fast but not immediate. It creates samples and sends them to storage outside of the instances. Which type of instance is ideal for a process like this; short lived and one that keeps the cost low?
The explanation is that preemptible instances are VM instances that offer lower costs than regular instances but can be reclaimed by OCI at any time due to capacity constraints or after running for a maximum of 24 hours. Preemptible instances are ideal for short-lived and stateless workloads that can tolerate interruptions and do not require guaranteed availability or performance. Preemptible instances are billed by the second at a fixed rate that is lower than regular instances.
You want a full-featured Identity-as-a-Service (IDaaS) solution that helps you manage workforce authentication and access to all of your Oracle and non-Oracle applications, whether they are SaaS apps, on-premises enterprise apps, or apps that are hosted in the cloud. Which IAM Identity Domain type should you create?
Premium is the IAM Identity Domain type that you should create if you want a full-featured IDaaS solution that helps you manage workforce authentication and access to all of your Oracle and non-Oracle applications. Premium Identity Domain provides users with access to Oracle Identity Cloud Service, which is an IDaaS solution that offers identity management, single sign-on, multifactor authentication, identity governance, and integration with third-party applications. The other options are not IAM Identity Domain types that provide a full-featured IDaaS solution. Reference: [Identity Domains], [Oracle Identity Cloud Service]
