Hypervisor
A Hypervisor is like a manager for computer systems that allows one physical computer to run multiple separate virtual computers at the same time. Think of it as a hotel manager who can divide one large building into many separate rooms for different guests. Common examples include VMware, Hyper-V, and Xen. Companies use hypervisors to save money on hardware and make their computer systems more efficient. When someone mentions "virtualization platform" or "virtual machine monitor" in their resume, they're usually talking about hypervisor technology.

Example Interview Questions
Senior Level Questions
Q: How would you plan a large-scale virtualization deployment for a company?
Expected Answer: Should discuss capacity planning, hardware requirements, backup strategies, disaster recovery, and how to choose the right hypervisor type for different business needs.
Q: How do you handle resource allocation and performance optimization in a virtualized environment?
Expected Answer: Should explain how to balance resources like memory and processing power between virtual machines, monitoring tools, and troubleshooting performance issues.
Mid Level Questions
Q: What's the difference between Type 1 and Type 2 hypervisors?
Expected Answer: Should explain that Type 1 runs directly on hardware (like VMware ESXi) and Type 2 runs on top of an operating system (like VirtualBox), and when to use each.
Q: How do you ensure high availability in a virtualized environment?
Expected Answer: Should discuss backup strategies, failover configurations, and tools used to maintain continuous operation of virtual machines.
Junior Level Questions
Q: What is a virtual machine and how does it work?
Expected Answer: Should be able to explain that a virtual machine is like a computer within a computer, running its own operating system and applications independently.
Q: What basic maintenance tasks do you perform on virtual machines?
Expected Answer: Should mention tasks like creating backups, updating virtual hardware, managing snapshots, and monitoring resource usage.
