100-140 Question 312
Select 3A company is migrating its on-premises data center to the cloud and is considering using virtualization to optimize resource usage. Which of the following terms correctly describe aspects of virtualization and cloud computing during this process?
- A
Hypervisor
- B
Elasticity
- C
Bare-metal server
- D
Pay-as-you-go
- E
Patch management
Show answer and explanation
Correct answers: A, B, D
Explanation
The correct answers 'Hypervisor,' 'Elasticity,' and 'Pay-as-you-go' represent foundational concepts in virtualization and cloud computing. A hypervisor enables the creation and management of virtual machines, elasticity is a core feature of cloud platforms, and the pay-as-you-go model reflects the cost-effectiveness of cloud services. These concepts are critical for understanding how virtualization and cloud computing are utilized in a migration scenario.
- A. Correct.
A hypervisor is a key component in virtualization as it allows multiple virtual machines (VMs) to run on a single physical machine by managing hardware resources.
- B. Correct.
Elasticity refers to the ability of cloud resources to dynamically scale up or down based on demand, which is a core concept of cloud computing.
- C. Incorrect.
A bare-metal server is a physical server without a virtualization layer. While it may be used in some cloud environments, it does not directly describe virtualization or typical cloud terminology in this scenario.
- D. Correct.
Pay-as-you-go is a payment model in cloud computing where users pay only for the resources they use. This term is relevant to cloud computing in the context of migration to the cloud.
- E. Incorrect.
Patch management refers to the process of updating systems to fix software vulnerabilities or improve performance. While important for IT operations, it is not directly tied to virtualization or cloud terminology.
