   A startup is choosing between virtual machines and containers for a new cloud-based application. They expect highly variable traffic and want to minimize cost while maintaining the ability to run multiple isolated services. The application is stateless and can be scaled horizontally. Which consideration is most important in this decision?

   • AContainers cannot be used in the cloud because they require a specific host OS.
   • BContainers have lower overhead and faster startup, allowing more efficient scaling and cost savings under variable load.
   • CVMs provide stronger security isolation, which is essential for multi-tenant environments.
   • DVMs are easier to manage because they do not require orchestration.

   An organization is deciding between virtual machines and containers for a new application. The application has variable workloads that spike during business hours and drop at night. The organization wants to minimize cost while ensuring the application can handle spikes. Which approach is most appropriate?

   • ADeploy the application on a fixed number of virtual machines sized for peak load
   • BDeploy the application in containers that can be scaled horizontally based on demand
   • CUse containers on a single VM without scaling
   • DUse a single large virtual machine to handle all workloads
