Which option describes how NFV, OpenStack, and KVM relate to each other?
Click on the arrows to vote for the correct answer
A. B. C. D.C.
NFV (Network Function Virtualization) is a concept that aims to replace traditional hardware-based networking equipment with software-based virtualized instances that can run on standard computing hardware. It allows service providers to reduce their capital expenditure (CAPEX) and operational expenditure (OPEX) by simplifying the management of network resources.
OpenStack is an open-source software platform that provides a cloud computing environment for managing virtualized resources such as compute, storage, and networking. It is widely used in the industry for creating private and public cloud infrastructures. OpenStack allows administrators to provision and manage virtual machines (VMs) running on KVM (Kernel-based Virtual Machine), an open-source virtualization technology that provides hardware-assisted virtualization for Linux environments.
KVM is a virtualization technology that allows multiple virtual machines to run on a single physical machine. KVM is integrated into the Linux kernel and is widely used in cloud computing environments because of its low overhead and good performance.
Now, coming back to the question, the relationship between NFV, OpenStack, and KVM can be understood as follows:
Option A: OpenStack and NFV enable KVM. This option is incorrect as KVM is a virtualization technology that is already enabled and does not require OpenStack or NFV to function.
Option B: NFV and KVM are based on OpenStack. This option is also incorrect as NFV and KVM are not based on OpenStack. OpenStack is a cloud computing platform that can be used to manage virtualized resources, including KVM-based VMs, but it is not a prerequisite for NFV or KVM.
Option C: OpenStack and KVM can be used to provide NFV. This option is correct. OpenStack and KVM can be used together to provide NFV. OpenStack provides the cloud infrastructure and management capabilities, while KVM provides the virtualization technology to run the virtualized network functions (VNFs) required for NFV.
Option D: OpenStack and KVM are not related to NFV. This option is incorrect, as OpenStack and KVM are indeed related to NFV, as explained in option C.
In conclusion, option C describes the correct relationship between NFV, OpenStack, and KVM.
