100-140 Question 313
Select 3A company is planning to migrate its on-premises infrastructure to the cloud. The IT team discusses using 'virtualization' to optimize their resources during the transition. Which of the following correctly represents virtualization and related cloud terminology in this scenario?
- A
Virtualization allows multiple virtual machines to run on a single physical server, sharing its resources.
- B
The cloud eliminates the need for virtualization entirely by relying only on physical servers.
- C
A hypervisor is required to manage and allocate resources to virtual machines on a physical server.
- D
Public cloud providers rely on virtualization to offer scalable and flexible resources to customers.
- E
Virtualization automatically guarantees 100% availability for any workloads deployed on virtual machines.
Show answer and explanation
Correct answers: A, C, D
Explanation
Virtualization is a foundational technology for cloud computing, enabling multiple virtual machines to operate on a single physical server through the use of a hypervisor. This allows cloud providers to offer scalable and flexible resources to customers. However, virtualization alone does not guarantee availability, making additional measures like redundancy critical for uptime.
- A. Correct.
Correct: Virtualization enables multiple virtual machines (VMs) to run on a single physical server, allowing better resource utilization and cost efficiency.
- B. Incorrect.
Incorrect: The cloud heavily relies on virtualization to provide flexibility and scalability, not just physical servers.
- C. Correct.
Correct: A hypervisor is a key component of virtualization, as it manages the creation, operation, and allocation of resources to virtual machines.
- D. Correct.
Correct: Public cloud providers use virtualization to deliver flexible and scalable compute, storage, and networking resources to customers.
- E. Incorrect.
Incorrect: While virtualization improves resource efficiency, it does not inherently guarantee 100% availability. Availability depends on additional factors such as redundancy, failover mechanisms, and cloud service-level agreements (SLAs).
