Which are valid statements about Cisco Virtual Interface Card (VIC)? (Choose two.)
A. The Cisco VIC can create an unlimited number of Virtual NICs.
B. The number of vNICs on the Cisco VIC that can be created is determined by the number of chassis uplinks.
C. vNICs are created using software on the host operating system.
D. The host operating system sees a vNIC as a physical PCIe device.
E. The host operating system sees a vNIC as a sub-interface of a primary NIC.
F. The Cisco VIC can create 1024 vNICs.
Correct Answer: BD

Explanation:
While this ASIC is capable of PCIe single-root I/O virtualization (SR-IOV), that functionality is not in play on these servers, as shown in Figure 9. The key to Cisco interface virtualization technology, as it has been since the first generation, is that the vNIC and sNIC are represented as PCIe physical functions (devices), not virtual functions (devices) created on the PCIe tree for the individual server. This allows the OS to see each vNIC as a uniquely configurable and manageable Ethernet interface and each storage controller as a specific device capable of communicating with mapped virtual drives within the infrastructure. In contrast, SR-IOV devices are virtual functions (devices) within a physical function (device). A virtual function is not a fullfeatured resource, as it relies on the physical function for all configuration resources. An SR-IOV device also requires software support in the OS. Within Cisco virtualization technologies, the sNIC and vNIC are presented to the OS as fully configurable physical functions that require no SR-IOV support.
