What is a common disadvantage of running many virtual machines on a single physical host?

Virtual machines cannot be moved between physical hosts

Increased overhead from running multiple full operating systems can reduce overall performance

Virtual machines require more physical hardware than running applications directly on the host

Virtual machines are less secure than physical servers because they share the same hardware

A company wants to test a new operating system without affecting the current production environment. They have limited hardware and want to run the test OS alongside the production OS. What is the most efficient way to do this?

Install the new OS on a separate partition and dual-boot

Use a virtual machine to run the new OS

Use containers to run the new OS

Replace the production OS with the new OS

What is the primary function of a hypervisor in a virtualized environment?

To provide a graphical user interface for the host operating system

To create and manage virtual machines by allocating physical hardware resources

To encrypt data stored on physical disks

To compile source code into executable programs

A company is planning to virtualize its infrastructure. They have a mix of workloads: some are I/O-intensive, some are CPU-intensive, and some are memory-intensive. They have a limited budget and want to maximize the use of existing hardware. Which approach is most effective?

Use overcommitment for all resources to maximize density.

Place workloads with complementary resource profiles on the same host.

Assign each workload to a dedicated physical server.

Place all CPU-intensive workloads on one host and all I/O-intensive workloads on another.

What is the primary purpose of cache memory in a computer system?

To expand the amount of RAM available to applications

To store frequently accessed data for faster retrieval by the CPU

To provide permanent storage for the operating system

To store the computer's firmware and boot instructions
