   An IT administrator wants to run three different operating systems on a single physical server to consolidate hardware and reduce power consumption. Each OS must be fully isolated with its own kernel. Which technology should the administrator use?

   • AContainerization on a shared host OS
   • BDual-boot configuration
   • CA hypervisor to create multiple virtual machines
   • DEmulation software that translates system calls

   What is a primary advantage of virtualization in terms of cost and resource utilization?

   • AIt eliminates the need for any physical hardware in a data center
   • BIt removes the need for operating system licenses for each virtual machine
   • CIt guarantees that applications run faster than on physical hardware
   • DIt allows multiple virtual servers to run on fewer physical machines, improving hardware utilization and reducing hardware costs

   A development team needs to test a web application in an environment that closely matches production. They want to run the same application code with different configuration files for each test run, and they need to start and stop test environments quickly. Which approach is most efficient?

   • AModify the production server configuration for each test
   • BCreate a new virtual machine for each test run
   • CUse containers with environment variables for configuration
   • DUse a single container and change its filesystem each time

   A company is considering virtualizing its servers to reduce hardware costs. They have a mix of workloads: some are mission-critical with strict performance requirements, while others are non-critical and can tolerate occasional slowdowns. The budget is limited, and they want to maximize consolidation. Which strategy best balances risk and cost?

   • AAvoid virtualization entirely to maintain performance.
   • BUse containers for all workloads to reduce overhead and increase density.
   • CPlace mission-critical workloads on dedicated hosts and consolidate non-critical workloads with overcommitment.
   • DConsolidate all workloads onto a single host with overcommitment to maximize density.
