Question 9

Which of the following statements describe disadvantages of virtualization? (Select 2 answers)

• Performance is degraded by having multiple virtual machines that run on a single host and share hardware resources
• In a virtualized environment, deployment of different types of OSs or multiple copies of the same OS or application becomes more difficult due to hardware configuration issues
• On a larger scale, virtualization has a negative effect on operational costs due to increased power supply requirements
• Hardware used for hosting virtual machines becomes a single point of failure

Answer 9

• Hardware used for hosting virtual machines becomes a single point of failure
• Performance is degraded by having multiple virtual machines that run on a single host and share hardware resources
