Apply Latest Kernel Security Updates to Oracle Linux Instances in OCI

B.

The OCI service that will allow you to manage updates and patches across all your compute instances running Oracle Linux in OCI is the OS Management service (Option B).

The OS Management service provides automated tools to manage and automate patching and updates for your Oracle Linux instances. You can use the OS Management service to create and manage software packages, apply updates and patches, and track compliance across all your instances.

To use the OS Management service, you need to first set up an OS Management Agent on each instance. The agent communicates with the OS Management service to apply patches and updates. You can use the OS Management console to manage the agent installation and configuration, schedule patching jobs, and view compliance reports.

Option A, Resource Manager, is an OCI service that helps you automate the deployment and management of infrastructure resources. It is not specifically designed for managing updates and patches.

Option C, Storage Gateway, is an OCI service that allows you to integrate your on-premises applications with OCI object storage. It is not related to managing updates and patches.

Option D, Streaming, is an OCI service that allows you to ingest, process, and analyze streaming data in real-time. It is not related to managing updates and patches.

Option E, Registry, is an OCI service that allows you to store, manage, and deploy Docker images in OCI. It is not related to managing updates and patches for Oracle Linux instances.

Therefore, the correct answer is Option B, OS Management.
