   Which statement correctly describes the isolation level provided by containers compared to virtual machines?

   • ABoth containers and virtual machines provide the same level of isolation because they both use a hypervisor
   • BVirtual machines have weaker isolation because they share the host operating system
   • CContainers provide stronger isolation because they are smaller and use fewer resources
   • DVirtual machines provide stronger isolation because each VM runs its own operating system, while containers share the host kernel

   A small startup runs a web application as a set of microservices on a single Linux server. Each microservice has its own dependencies and needs to be isolated from the others, but the team wants to minimize overhead and start new instances in under a second. Which approach best meets these requirements?

   • ADeploy each microservice as a separate virtual machine on the server
   • BUse a hypervisor to run each microservice in a separate kernel namespace
   • CRun each microservice as a container on the server using the host kernel
   • DInstall all microservices directly on the host OS without isolation

   A company wants to reduce its data center footprint by running multiple isolated servers on fewer physical machines. Each server runs a different operating system and must be managed independently. What is the most appropriate solution?

   • AReplace each server with a separate physical machine
   • BUse application virtualization on a single OS
   • CDeploy containers on a single host OS
   • DUse a hypervisor to run multiple VMs on each physical server
