- D . A broadcast domain, using only virtual machines
Question #19
What happens if a frame with a known destination MAC address enters a switch?
- A . The egress PFE performs a MAC address lookup and determines the ingress PFE and port.
- B . The ingress PFE sends the header information to the RE.
- C . The ingress PFE performs a MAC address lookup and determines the egress PFE and port.

Question #20
What is an advantage of using BFD?
- A . BFD is so lightweight that each protocol will generate its own unique BFD session by default, to replace its own hello messages.
- B . BFD built to handle the routing table of the entire Internet, and can safely redistribute it into OSPF.
- C . One BFD monitoring session can be used by multiple protocols.
- D . BFD is built to handle the routing table of the entire Internet, unlike IGPS.
