What are two advantages of using PC virtualization? (Choose two.) a)It protects the host machine from viruses attacks. b)It allows multiple operating systems to run on a single PC simultaneously. c)It boosts the performance of the host machine through virtualization. d)It can provide cost savings. e)It allows network threat identification.
The Correct Answer and Explanation is :
The correct answers are:
b) It allows multiple operating systems to run on a single PC simultaneously.
d) It can provide cost savings.
Explanation:
1. Allows Multiple Operating Systems to Run on a Single PC Simultaneously (b):
One of the main benefits of PC virtualization is its ability to run multiple operating systems (OS) on a single physical machine. Virtualization software (like VMware, VirtualBox, or Hyper-V) creates virtual machines (VMs) that emulate the hardware of an actual computer, allowing different operating systems to operate in isolated environments simultaneously. For instance, a single physical PC can run Windows, Linux, and macOS concurrently without needing to dual-boot or physically separate hardware. This enables developers, testers, and IT administrators to work in multiple OS environments without the need for separate computers for each system. It also facilitates tasks such as cross-platform software testing, legacy application support, or running specialized applications that are only compatible with certain operating systems.
2. Can Provide Cost Savings (d):
Virtualization provides cost savings by reducing the need for multiple physical machines. By running multiple virtual machines on a single physical server or desktop, businesses can maximize their hardware investment and reduce expenses related to hardware acquisition, maintenance, and energy consumption. This can result in fewer physical servers or workstations required in a company’s infrastructure, which can lower capital and operational expenditures. Additionally, virtualization makes it easier to scale up resources as needed without purchasing new physical hardware. IT administrators can allocate more resources (such as CPU, RAM, and disk space) to a virtual machine when needed, which provides flexibility and reduces the financial burden of maintaining separate hardware for each service or department.
Why Other Options are Incorrect:
- a) It protects the host machine from virus attacks: Virtualization does not inherently protect the host machine from viruses. Virtual machines can still be infected by malware if not properly secured.
- c) It boosts the performance of the host machine: Virtualization typically consumes some system resources to create and manage virtual machines, so it may slightly reduce performance rather than increase it.
- e) It allows network threat identification: While virtualization can be used in security testing environments (e.g., penetration testing), it is not directly related to identifying network threats.
Thus, the advantages of virtualization primarily include running multiple OSes on one PC and providing cost savings.
