vRAM
vRAM (Virtual RAM) is a key concept in computer virtualization where physical memory resources are shared and allocated among virtual machines. Think of it like dividing up and managing the computer's memory to support multiple virtual computers running at the same time. When you see this term in resumes, it typically refers to experience with memory management in virtual environments, particularly with platforms like VMware vSphere. It's similar to how you might share a pie among guests, but with computer memory - making sure each virtual machine gets the right amount it needs to run properly.

Example Interview Questions
Senior Level Questions
Q: How would you plan vRAM allocation in a large enterprise environment?
Expected Answer: A senior candidate should explain how they would assess business needs, calculate total memory requirements, plan for peak usage, and implement monitoring and adjustment strategies. They should mention experience with handling memory-intensive applications and emergency situations.
Q: What strategies have you used to optimize vRAM usage?
Expected Answer: They should discuss practical examples of memory optimization, such as identifying memory waste, implementing memory sharing techniques, and using monitoring tools to track and improve memory usage patterns.
Mid Level Questions
Q: How do you monitor vRAM usage and handle memory pressure?
Expected Answer: Should explain basic monitoring tools, common memory pressure signs, and standard procedures for addressing memory issues, including reallocation and troubleshooting steps.
Q: Explain how you would handle a situation where VMs are experiencing memory constraints?
Expected Answer: Should describe the process of identifying memory problems, adjusting allocations, and implementing both short-term fixes and long-term solutions to prevent future issues.
Junior Level Questions
Q: What is vRAM and why is it important in virtualization?
Expected Answer: Should be able to explain that vRAM is virtual memory allocated to virtual machines, and why proper memory allocation is crucial for system performance.
Q: How do you assign vRAM to a virtual machine?
Expected Answer: Should demonstrate basic knowledge of allocating memory to virtual machines through virtualization platforms and understanding of minimum/recommended memory requirements.
