Exam CV0-003 topic 1 question 290 discussion

To maintain the same level of network throughput and latency when migrating an integration application from a physical machine to a virtual server, you should consider enabling SR-IOV (Single Root I/O Virtualization) capability. SR-IOV is a technology that allows virtual machines (VMs) to have direct, hardware-level access to network interfaces. It can significantly improve network performance and reduce latency for VMs by bypassing the hypervisor's network stack. So, the answer is: C. Enabling SR-IOV capability. Enabling SR-IOV for the VM's network interface will help maintain network performance similar to what was experienced on the physical server.

Single-root I/O virtualization (SR-IOV) allows multiple VMs to share the same physical network interface card (NIC) on a VM host. SR-IOV effectively virtualizes a single NIC as multiple virtual NICs, each of which can connect to a different VM. This allows rapid, direct communication between the VM and the physical NIC without the need for the hypervisor to perform any virtual switching.

SR-IOV seems to be the only valid answer.

As explained by Ckl22.

The answer is C, SR-IOV, which would provide throughput similar/identical to that of a physical NIC The single root I/O virtualization (SR-IOV) interface is an extension to the PCI Express (PCIe) specification. SR-IOV allows a device, such as a network adapter, to separate access to its resources among various PCIe hardware functions.
