Big Data Analytics | Hypervisor MCQs: This section contains the Multiple-Choice Questions & Answers on Big Data Analytics - Hypervisor with explanations.
Submitted by IncludeHelp, on January 13, 2022

1. A hypervisor is a technology responsible for ensuring ____ takes place in an orderly and repeatable way.

  1. Operating system
  2. Resource sharing
  3. System integration
  4. None of the mentioned above

Answer: B) Resource sharing

Explanation:

A hypervisor is the technology that is in charge of ensuring that resource sharing occurs in a systematic and repeatable manner. Because it is located at the lowest levels of the hardware environment, the hypervisor only requires a minimal layer of code to allow for dynamic resource sharing. The hypervisor gives the impression that each operating system has complete control over the physical resources.


2. Hypervisor is a practical approach of getting things virtualized _______.

  1. Quickly and efficiently
  2. Systematic approach
  3. Both A and B
  4. All of the mentioned above

Answer: A) Quickly and efficiently

Explanation:

With the advent of the hypervisor, the technology components of the big data stack may be delivered in an optimal manner. The hypervisor enables you to display the same application on multiple systems without having to physically copy the application to each device in question. It has the ability to load any number of operating systems as if they were simply another application on the computer. Consequently, the hypervisor is a very practical tool for swiftly and efficiently virtualizing a variety of resources.


3. TYPE-1 Hypervisor runs directly on the underlying host system. It is also known as "Native Hypervisor" or "Bare metal hypervisor".

  1. True
  2. False

Answer: A) True

Explanation:

The TYPE-1 hypervisor is a virtual machine that operates on top of the underlying host system. It is also referred to as a "Native Hypervisor" or a "Bare metal hypervisor" in some circles. It is not necessary to have a base server operating system installed. It has direct access to the hardware resources available to it.


4. Type-2 Hypervisor is also known as "Hosted Hypervisor".

  1. True
  2. False

Answer: A) True

Explanation:

A host operating system is a system that runs on top of a host system. It is also referred to as a "Hosted Hypervisor." In contrast to traditional hypervisors, which run directly on the underlying hardware, such hypervisors run as an application on the host system (physical machine).


5. Type-2 Hypervisor allows quick and easy access to a guest _____ alongside the host machine running.

  1. Application software
  2. System software
  3. Operating System
  4. None of the mentioned above

Answer: C) Operating System

Explanation:

Type-2 hypervisors allow for rapid and easy access to a guest operating system while the host computer is still running on the same physical hardware. These hypervisors are typically equipped with additional functions that are beneficial to the guest system. These types of tools improve the synchronization between the host machine and the guest computer.


6. A hypervisor is a form of ____ used in Cloud hosting to divide and allocate the resources on various pieces of hardware.

  1. Virtualization software
  2. System software
  3. Integrated approach
  4. None of the mentioned above

Answer: A) Virtualization software

Explanation:

When it comes to Cloud hosting, a hypervisor is a type of virtualization software that is used to divide and allocate resources across multiple pieces of hardware. The program that offers partitioning, isolation, and abstraction is referred to as a hypervisor in virtualization technology. When used in conjunction with a host system, the hypervisor is a hardware virtualization method that allows many guests operating systems to coexist on a single host system.


7. Hypervisors support the creation and management of virtual machines,

  1. True
  2. False

Answer: A) True

Explanation:

Hypervisors enable the construction and control of virtual machines (VMs) by abstracting the software running on a computer from the hardware on which it is running. In order for virtualization to be possible, hypervisors must be used to translate requests between physical and virtual resources.


8. Hypervisors that run several virtual machines on one ____ resources also allow for more efficient utilization,

  1. Physical machine
  2. Abstract machine
  3. System integration
  4. All of the mentioned above

Answer: A) Physical machine

Explanation:

Virtualization technologies such as hypervisors, which allow several virtual computers to share the resources of a single physical machine, allow for more efficient utilization of a single physical server. It is more cost and energy-efficient to run several virtual machines on a single physical computer than it is to run multiple underutilized real machines for the same work on multiple underutilized physical machines.


9. Virtual machines that the hypervisor runs are independent from the physical machine,

  1. True
  2. False

Answer: A) True

Explanation:

The virtual machines that are run by the hypervisor are completely independent of the real machine and are therefore portable. As workloads change, IT professionals can move them from one machine to another or from one platform to another, allocating networking, memory, storage, and processing resources as needed across numerous servers. When a program requires greater processing power, virtualization software enables it to access new machines without having to restart the program.


10. Hypervisors are used for many different tasks, including ____ server management, and simply running programs.

  1. Cloud computing
  2. Security management
  3. Integrated approach
  4. None of the mentioned above

Answer: A) Cloud computing

Explanation:

In addition to cloud computing and server administration, hypervisors are used for a variety of other purposes, including as executing program that are compatible with operating systems that we do not currently have access to. In order to run processes and operating systems on virtual machines that are completely distinct from your main system, we can utilize a hypervisor.
