CompTIA A+ Certification 220-1001: The Total Course - Understanding Virtualization

What is the main difference between virtualization and emulation?

• Virtualization is used for gaming, while emulation is not.

• Virtualization uses real hardware, while emulation mimics hardware.

• Emulation requires a hypervisor, while virtualization does not.

• Virtualization is slower than emulation.

What is necessary for a computer to support virtualization?

• An external hard drive

• A specific type of graphics card

• A CPU that supports virtualization

• A special type of RAM

Which of the following is a characteristic of a Type 1 hypervisor?

• It requires a dual-core processor.

• It is installed directly on the hardware.

• It runs on top of an existing operating system.

• It is only compatible with Windows.

How does a Type 2 hypervisor operate?

• It runs directly on the hardware without an OS.

• It operates as an application on an existing OS.

• It is only used for cloud computing.

• It requires a dedicated server.

Which hypervisor is known for being free and widely used?

• Oracle VM VirtualBox

• KVM

• Microsoft Hyper-V

• VMware ESXi

What is a common use case for Type 2 hypervisors?

• Running multiple operating systems on a personal computer.

• Managing large data centers.

• Creating video games.

• Developing mobile applications.

What is a key advantage of using virtual machines?

• They increase power consumption.

• They require more physical space.

• They are slower than physical machines.

• They offer enhanced security and recovery options.

What happens to a virtual machine when it is turned off?

• It becomes a file on the hard drive.

• It continues to run in the background.

• It requires reinstallation to start again.

• It is deleted permanently.

What is a benefit of using virtual networks?

• They require more physical cables.

• They allow for isolated network setups.

• They are slower than physical networks.

• They need special hardware to function.

Why are Type 1 hypervisors preferred for robust systems?

• They provide direct access to hardware.

• They require less technical knowledge.

• They are cheaper than Type 2 hypervisors.

• They are easier to install.
