The maximum number of virtual interfaces that can be created on a virtual interface card (VIC) is impacted by multiple factors. Two of the factors that impact the maximum number of virtual interfaces that can be created on a VIC are:

B. Number of acknowledged links between the Fabric Interconnect and the I/O module: The number of acknowledged links between the Fabric Interconnect and the I/O module determines the maximum bandwidth available to the VIC. Each link between the Fabric Interconnect and the I/O module provides a fixed amount of bandwidth. The maximum number of virtual interfaces that can be created on a VIC is directly proportional to the amount of available bandwidth. Therefore, the more acknowledged links between the Fabric Interconnect and the I/O module, the higher the maximum number of virtual interfaces that can be created on the VIC.

D. Number of Fabric Interconnect port ASICs used by uplinks: Each uplink that is connected to a Fabric Interconnect port ASIC uses up some of the available resources on the ASIC. The more uplinks that are connected to a Fabric Interconnect port ASIC, the less resources are available for creating virtual interfaces. Therefore, the number of Fabric Interconnect port ASICs used by uplinks is a limiting factor on the maximum number of virtual interfaces that can be created on a VIC.

A. Number of blades in the chassis, C. Number of connected uplinks, E. Number of Fabric Interconnects, and F. Number of VICs may indirectly impact the maximum number of virtual interfaces that can be created on a VIC. However, they are not direct limiting factors on the maximum number of virtual interfaces that can be created on a VIC. Therefore, they are not the correct answers to this question.
