How does SR-IOV move data directly to and from the network adapter?
The correct answer is C. Bypassing the hypervisor. SR-IOV (Single Root I/O Virtualization) allows a VM to access the network interface hardware directly, without going through the hypervisor's virtual switch. This is achieved by: Assigning Virtual Functions (VFs) directly to VMs Allowing high-performance, low-latency packet I/O…

Explanation
SR-IOV (Single Root I/O Virtualization) allows a VM to access the network interface hardware directly, without going through the hypervisor's virtual switch. This is achieved by: Assigning Virtual Functions (VFs) directly to VMs Allowing high-performance, low-latency packet I/O Bypassing the hypervisor datapath Therefore, SR-IOV does not bypass the guest OS; it bypasses the hypervisor I/O virtualization layer, delivering near-native performance.
