Understanding Virtualization Concepts

What is virtualization?

• Virtualization is the creation of a virtual version of physical resources, allowing multiple instances to operate on a single hardware system.

• Virtualization refers to the duplication of software applications on multiple devices.

• Virtualization is the method of increasing the physical size of a computer's hard drive.

• Virtualization is the process of creating physical copies of hardware resources.

Which of the following is a type of hypervisor?

• Type 2 hypervisor

• Type 1 hypervisor

• Type B hypervisor

• Type A hypervisor

What is a primary benefit of virtualization?

• Limited scalability and flexibility.

• Increased hardware dependency and complexity.

• Improved resource utilization and cost savings.

• Higher energy consumption and maintenance costs.

What does server virtualization allow you to do?

• It allows multiple virtual servers to run on a single physical server.

• It restricts the number of servers that can be deployed on a network.

• It allows a single virtual server to run on multiple physical servers.

• It enables physical servers to operate without any virtualization.

What is the main difference between para-virtualization and full virtualization?

• The main difference is that para-virtualization requires modified guest OS, while full virtualization allows unmodified guest OS.

• Full virtualization requires modified guest OS.

• Para-virtualization is faster than full virtualization.

• Para-virtualization allows unmodified guest OS.

What is the role of a hypervisor in virtualization?

• To replace the operating system in virtual machines.

• The role of a hypervisor in virtualization is to manage and allocate hardware resources to multiple virtual machines.

• To store data for virtual machines.

• To provide a user interface for virtual machines.

In which scenario would you use full virtualization?

• When running multiple OS instances independently on a single host.

• When performing hardware-level resource management.

• When using a lightweight container for application isolation.

• When running a single OS instance on a dedicated server.

What is the taxonomy of virtualization primarily concerned with?

• Explaining the hardware requirements for virtualization.

• Analyzing the performance metrics of virtualization systems.

• Defining the history of virtualization technologies.

• Categorizing different types of virtualization technologies and their applications.

Which of the following is NOT a type of virtualization?

• Network Virtualization
  

• Server Virtualization
  

• Mobile Virtualization

• Storage Virtualization

Which type of hypervisor runs directly on the hardware?
