Which of the following is listed as a characteristic of hypervisors?

• A. Performance, Live Migration, cost
• B. Ecosystem, management tool, cloud
• C. Security, Reliability, Cost
• D. Scalability, Integration, Power

Answer: (A)

The main concept being tested is what properties are commonly associated with hypervisors as virtualization platforms. Hypervisors are designed to efficiently share hardware resources among multiple virtual machines, so the most relevant characteristics emphasize how this sharing happens and what it costs to operate. Performance reflects the virtualization overhead and how closely guest VMs can run at native speeds, especially with hardware-assisted virtualization features. Live Migration is a key capability that lets you move a running VM between physical hosts without downtime, which is crucial for maintenance, load balancing, and high availability. Cost matters because different hypervisors come with varying licensing models and total ownership costs, including hardware, software, and ongoing management. The other options mix in terms like ecosystem, broad security or reliability concerns, or general scalability and power, which are important in IT generally but do not pinpoint the defining, intrinsic features of hypervisors as directly as performance, live migration, and cost do.
