Q71.Marks: +2.0UGC NET Paper 2: Computer Science and Application 26th June 2025 Shift 1
Arrange the process of virtualization in cloud environments.
A. Hypervisor installed on physical server
B. Virtual machines created
C. Resources allocated to Virtual machines
D. Virtual machines run isolated workloads
Choose the correct answer from the options given below:
1.B, C, A, D
2.A, B, C, D✓ Correct
3.A, C, B, D
4.B, C, D, A
Solution
The correct answer is:Option 2
Key Points
Step A: ✅ The hypervisor is first installed on the physical server. A hypervisor is software that allows the creation and management of virtual machines. It acts as the interface between the physical hardware and virtual machines.
Step B: ✅ Virtual machines (VMs) are then created on the hypervisor. A virtual machine is an emulation of a computer system that runs on the physical server.
Step C: ✅ Resources such as CPU, memory, storage, and network bandwidth are allocated to each virtual machine. These resources are divided and shared among the VMs as per requirements.
Step D: ✅ Finally, the virtual machines run isolated workloads. Each VM operates independently, ensuring that workloads are isolated from one another.
Additional Information
Hypervisor: There are two types of hypervisors:
Type 1 (Bare-metal): Runs directly on the physical hardware.
Type 2 (Hosted): Runs on a host operating system.
Isolation: Virtual machines are isolated from one another, ensuring that issues in one VM do not affect others.
Scalability: Virtualization allows for easy scalability by creating or removing VMs as needed.
Hence, the correct order of the process is:Option 2: A, B, C, D
