Which two methods are used by a single-root I/O virtualization (SR-IOV) enabled switch to switch traffic between VNFs? (Choose two.)

Question:
Which two methods are used by a single-root I/O virtualization (SR-IOV) enabled switch to switch traffic between VNFs? (Choose two.)

• through a DMVPN
• through a VXLAN
• through an external switch
• through the pNIC
• through a vSwitch

Explanation: An SR-IOV-enabled pNIC supports two different modes for switching traffic between VNFs:

• Virtual Ethernet Bridge (VEB): Traffic between VNFs attached to the same pNIC is hardware switched directly by the pNIC.
• Virtual Ethernet Port Aggregator (VEPA): Traffic between VNFs attached to the same pNIC is switched by an external switch.
