You are part of a project team working in the development environment created in Oracle Cloud Infrastructure (OCI). You realize that the CIDR block specified for one of the subnets in a Virtual Cloud Network (VCN) is not correct and want to delete the subnet. While deleting you get an error indicating that there are still resources that you must delete first. The error includes the OCID of the VNIC that is in the subnet.

You are responsible for a web application deployed on a set of compute VM instances in Oracle Cloud Infrastructure (OCI). Your application stores data on block volumes.
In production, the business requirement is a Recovery Point Objective (RPO) of two hours and that data should be recoverable in case of a regional failure.
How would you meet the RPO requirement in the event of a failure?
Your organization needs to migrate legacy monolithic applications into cloud-native containerized RESTful microservices. The development team is testing the use of packaged procedures with containers in a fully serverless environment. Before migrating the existing code to production, the team decides to perform a lift and shift of the monolithic application and code the new features that are essential for serverless microservices.
You want to carry out a steady migration to the Oracle Cloud Infrastructure (OCI) platform, making the new microservice functionalities available while maintaining the monolithic application for all the other activities. You also want to integrate the legacy monolithic application with the new microservices to have a single interface with simplified management for auditing and monitoring while meeting operational and compliance requirements.
How can you meet this requirement?
You work for a retail company and they developed a Microservices based shopping application that needs to access Oracle Autonomous Database from the application.
