100-140 Question 314
Select 3A company is planning to move its on-premises data center to the cloud and is considering virtualization as part of its strategy. Which of the following terms best describe the concept of virtualization and its role in cloud computing?
- A
Hypervisor
- B
Virtual Machine
- C
Bare-Metal Server
- D
Elasticity
- E
Containerization
Show answer and explanation
Correct answers: A, B, D
Explanation
Virtualization is the underlying technology that enables cloud computing by abstracting physical resources into virtual instances. Key terms like hypervisor, virtual machine, and elasticity are directly tied to how virtualization works and its role in dynamically scaling and managing resources in the cloud.
- A. Correct.
A hypervisor is a key component of virtualization, allowing multiple virtual machines to run on a single physical machine by managing hardware resources effectively.
- B. Correct.
A virtual machine (VM) is an emulated instance of a computer system that runs on a hypervisor and is a core element of virtualization.
- C. Incorrect.
A bare-metal server refers to physical hardware and is unrelated to virtualization as it does not involve abstraction of resources.
- D. Correct.
Elasticity is a fundamental cloud concept that allows resources to scale dynamically based on demand, often achieved through virtualization.
- E. Incorrect.
Containerization is a related technology but is not strictly part of traditional virtualization terminology. Containers operate at the application layer and do not rely on hypervisors in the same way VMs do.
