Explanation: In Oracle Cloud Infrastructure (OCI), cross -region access is facilitated by configuring IAM policies that grant users or groups permissions to access resources in other regions. IAM policies in OCI are global, meaning they apply across all regions by default. However, an administrator can specifically configure these policies to allow or restrict access to resources in different regions. Example: An administrator can write a policy that allows a user to manage compute instances in a specific region by including the region's name in the policy statement.

Explanation: When performing a multipart upload using the Multipart Upload API in Oracle Cloud Infrastructure (OCI) Object Storage, the following points are true: C . Each part can be as large as 50 GiB: OCI allows each part of a multipart upload to be up to 50 GiB in size. This enables the efficient uploading of large objects in smaller, manageable parts. D . You can keep adding parts as long as the total number is less than 10,000: The Multipart Upload API supports up to 10,000 parts for a single object. This allows the upload of very large objects by dividing them into multiple parts. Incorrect Statements: A . After uploading all parts, you must commit the upload to finalize the multipart upload and combine all parts into a single object. B . The object must be split into parts before uploading when using the Multipart Upload API. Reference: Oracle Cloud Infrastructure Documentation: Multipart Uploads Which OCI service would you use to apply kernel security updates to all instances?
management. Relevant OCI Documentation: OS Management Service Overview This documentation provides details on how to use OS Management Service to handle kernel security updates and other OS -level management tasks. Which statement is true about pre -authenticated requests?
Enable Oracle Cloud Guard in the tenancy to automatically detect and respond to security misconfigurations and threats. -> Correct. Cloud Guard acts as a security monitoring and response system by detecting misconfigurations, threats, and anomalous activities within OCI environments, making it a critical component for enhancing security posture. Configure Oracle Data Safe for all databases to manage sensitive data through discovery, masking, and auditing. -> Correct. Oracle Data Safe provides a unified control center for managing sensitive data and improving security across OCI databases by offering features like sensitive data discovery, data masking, and activity auditing. Implement Oracle Identity Cloud Service (IDCS) for network security by configuring security lists and network security groups. -> Incorrect. While IDCS is a comprehensive identity management service, it is not directly used for configuring network security, which is typically managed through Virtual Cloud Networks (VCN) settings in OCI. Use OCI Email Delivery service for securing email communications with encryption in transit. -> Incorrect. Although OCI Email Delivery service supports secure email sending, it is not primarily a security service focused on the broader aspects of security posture management within OCI. Install third -party antivirus software on all compute instances to protect against malware and threats. -> Incorrect. While installing antivirus might be a part of an overall security strategy, it's not specific to leveraging OCI's built -in security services, which offer a wide range of cloud -native security solutions. When configuring the OS Management service for an existing Compute instance, which of the following actions is required to enable automatic management of the operating system's updates and patches?
Associate the Compute instance with a dedicated Virtual Cloud Network (VCN) specifically configured for OS Management. -> Incorrect. While network configurations are important, a dedicated VCN for OS Management is not necessary. Install a third -party management agent on the Compute instance. -> Incorrect. Installing a third -party agent is not required since OCI provides its own OS Management service agent. A company is planning to migrate its data processing application to Oracle Cloud Infrastructure (OCI). The application requires a high degree of compute performance for large -scale numerical simulations. The workload involves both CPU -intensive computations and GPU -accelerated tasks. Given the need for flexibility in scaling and managing compute resources, which of the following compute options should the company choose?
Explanation of Incorrect Options: Option A: Creating a new Object Storage bucket in another region and configuring a recycle policy to move data every 5 days does not provide real-time data availability or the fault tolerance required for a financial application. Recycle policies are intended for managing the lifecycle of data, not for high availability or disaster recovery. Option C: While lifecycle policies are useful for moving less frequently accessed data to a more cost - effective storage tier (e.g., from Standard to Archive), they do not address cross -region redundancy or real-time availability, which are critical for this use case. Option D: Copying an Object Storage bucket to a block volume is not a recommended practice for ensuring data durability and fault tolerance. Block volumes are used for persistent storage attached to compute instances, and copying object storage data to block volumes does not achieve the same level of redundancy and cross -region availability as replication policies. Thus, Option B is the correct and most efficient method for ensuring high availability and fault tolerance in this scenario. Which TWO statements are TRUE about Private IP addresses in Oracle Cloud Infrastructure (OCI)?
