VMCE Virtualization & Cloud Infrastructure Management — Questions and Answers
Question 1: What is the main benefit of virtualization in data centers?
- It improves the physical space in data centers.
- It reduces hardware costs by using fewer physical servers (Correct answer)
- It simplifies cloud migration.
- It speeds up network communication.
Correct answer: It reduces hardware costs by using fewer physical servers
The main benefit of virtualization in data centers is its ability to consolidate multiple virtual machines onto a single physical server. This significantly reduces the number of physical servers required, leading to lower hardware acquisition costs, reduced power consumption, less cooling, and a smaller physical footprint. By maximizing hardware utilization, virtualization drives substantial cost savings and operational efficiency.
Question 2: Which of the following is an example of cloud infrastructure?
- Virtualization software.
- Servers, storage, and network hardware (Correct answer)
- Operating systems.
- Backup software.
Correct answer: Servers, storage, and network hardware
Cloud infrastructure refers to the underlying physical and virtual components that support cloud computing. This typically includes physical servers, storage devices (like SANs or NAS), and networking hardware (routers, switches, firewalls) that are interconnected and managed to deliver computing resources as a service. Virtualization software runs on this hardware to create the virtualized environment that users interact with.
