   A security auditor is reviewing a company's deployment. The company runs a multi-tenant application where each customer's data must be strongly isolated. The application is currently containerized. The auditor notes that containers share the host kernel, which could be a risk. What is the most appropriate action to address this concern?

   • AUse containers with the same image for all customers to simplify management.
   • BRun each customer's workload in a separate VM while using containers inside the VM for application packaging.
   • CUse a container orchestrator to isolate workloads by namespace.
   • DDisable the container runtime's network access to prevent data leakage.

   A company is running a long-running, stateful analytics workload that processes streaming data. The workload is currently running on a single VM. They want to move to a containerized platform to improve scalability and resilience. Which consideration is most important when designing the containerized solution?

   • AThe workload should be run on a single container with a large resource limit.
   • BThe workload must use persistent storage that is accessible from any node in the cluster.
   • CThe workload should be moved to a serverless function to avoid managing infrastructure.
   • DThe workload should be split into multiple stateless microservices to simplify scaling.

   A development team is building a microservices application. They want to ensure that the exact same runtime environment is used in development, testing, and production. They also need to version their application components so they can roll back to a previous release if a deployment fails. Which set of actions should they take?

   • ACopy the application source code to each environment and compile it on the target server.
   • BCreate a VM template for each environment and store them in a shared folder.
   • CUse a configuration management tool to apply the same scripts to each environment.
