   A cloud-native application is designed so that any instance of a service can handle any request, and session state is stored in a shared cache rather than on the local instance. This design allows the service to scale horizontally and instances to be replaced without affecting users. Which design principle is being applied?

   • AScalability
   • BService discovery
   • CStatelessness
   • DResilience

   Which statement best describes a microservices architecture compared with a monolithic architecture?

   • AA microservices architecture uses a single shared database, while a monolithic architecture gives each service its own database.
   • BA microservices architecture structures the application as a collection of small, independently deployable services, while a monolithic architecture packages all functionality into one deployable unit.
   • CA microservices architecture deploys the entire application as a single unit, while a monolithic architecture splits it into independently deployable services.
   • DA microservices architecture runs only on public cloud, while a monolithic architecture runs only on-premises.

   Which statement correctly describes the role of containers in a cloud-native architecture?

   • AContainers provide a full operating system with a kernel for each application instance.
   • BContainers package an application and its dependencies into a portable unit that runs consistently across environments.
   • CContainers replace the need for virtual machines in all cloud environments.
   • DContainers are only used for stateless applications and cannot run stateful services.

   A team wants to adopt DevOps practices to improve collaboration between development and operations. They plan to automate infrastructure provisioning and application deployment, and they want to ensure that every code change is automatically tested and deployed to a staging environment. Which set of practices should they implement?

   • ASeparate development and operations teams with handoff documentation
   • BManual infrastructure setup and a nightly deployment script
   • CInfrastructure as code and a CI/CD pipeline that deploys to staging
   • DA single large release train that deploys all changes together
