What is true about the security patch application in OCI?

In Oracle Cloud Infrastructure (OCI), security patch application is designed to be seamless and to minimize disruptions for users. The correct statement emphasizes that security patches are automatically applied to ensure high availability. This automatic application is crucial because it allows OCI to maintain its infrastructure without requiring extensive downtime, thereby supporting the continuous operation of services.

By ensuring that security patches are applied automatically, OCI can quickly safeguard its environment against vulnerabilities, providing users with a more secure and reliable infrastructure. This proactive approach helps in maintaining service performance and availability, making it less likely for users to experience interruptions or to manage the patching process manually. This operational model is a key selling point of OCI, showcasing its commitment to security and reliability for enterprise workloads.

Other statements don't reflect the automated, high-availability features of OCI's security patch management. For instance, requiring downtime for all services would counter the very essence of cloud service offerings, while manual application would burden users with operational overhead. Limiting patch applications to certain services would not align with the overall goal of comprehensive security across the platform.
