Virtualization with Explainations

How familiar are you with virtualization?

• Fairly Knowledgeable

• So-So

• Used it

• Never Heard of it

What is virtualization primarily used for?

• To limit the number of applications running on a server.

• To optimize resource utilization and run multiple operating systems on a single physical machine.

• To increase hardware costs and complexity.

• To ensure only one operating system can be used at a time.

Answer explanation

Virtualization is primarily used to optimize resource utilization by allowing multiple operating systems to run on a single physical machine, enhancing efficiency and flexibility in managing resources.

What is a Hypervisor?

• a network protocol for data transfer.

• a type of physical server.

• a database management system.

• software that creates and runs virtual machines

Answer explanation

A hypervisor is software that creates and runs virtual machines, allowing multiple operating systems to operate on a single physical machine. This distinguishes it from other options like network protocols or database systems.

What is a Type 1 Hypervisor?

• a virtualization layer that runs directly on the physical hardware without a host operating system.

• a type of cloud storage service.

• a network protocol for data transmission.

• a software application that runs on a host operating system.

Answer explanation

A Type 1 Hypervisor is a virtualization layer that operates directly on physical hardware, allowing multiple operating systems to run concurrently without needing a host OS, making it efficient and powerful.

A type 1 Hypervisor

• Virtual Box

• a bare metal hypervisor

• an operating system

Answer explanation

A type 1 hypervisor, also known as a bare metal hypervisor, runs directly on the hardware without an underlying operating system. This allows for better performance and resource management compared to type 2 hypervisors like Virtual Box.

What is a Type 2 Hypervisor?

• only used for cloud computing.

• runs directly on hardware without a host OS.

• a virtualization layer that runs on top of a host operating system.

• a type of physical server.

Answer explanation

A Type 2 Hypervisor is a virtualization layer that runs on top of a host operating system, allowing multiple virtual machines to operate within that OS environment, unlike Type 1 which runs directly on hardware.

Which hypervisor is more secure?

• Type 1 hypervisors are less secure than bare-metal servers.

• Both Type 1 and Type 2 hypervisors have the same level of security.

• Type 1 hypervisors are generally more secure than Type 2 hypervisors.

• Type 2 hypervisors are more secure than Type 1 hypervisors.

Answer explanation

Type 1 hypervisors run directly on hardware, providing better isolation and security compared to Type 2 hypervisors, which run on a host operating system. This makes Type 1 hypervisors generally more secure.

(a)   is way to run multiple operating systems and user applications on the same hardware

• Data Mining

• Virtualization

• Storage

• Data Warehousing

Answer explanation

Virtualization allows multiple operating systems and applications to run on the same hardware by creating virtual environments. This technology optimizes resource use and enhances flexibility, making it the correct choice.

Which Hypervisor is used in Data Centers?

• Type 3 Hypervisor

• Type 1 Hypervisor

• Type A Hypervisor

• Type 2 Hypervisor

Answer explanation

Type 1 Hypervisors run directly on the hardware, providing better performance and efficiency, making them ideal for data centers. In contrast, Type 2 Hypervisors run on a host operating system, which is less suitable for such environments.

Benefits of Virtualization

• Isolation

• Hardware Independence, Portability

• Encapsulation

• Hardware Independence, Portability,Encapsulation,Isolation

Answer explanation

The correct choice includes all key benefits of virtualization: Hardware Independence, Portability, Encapsulation, and Isolation. These features enhance flexibility, resource utilization, and security in computing environments.
