Which of the following statements about the BFD echo function are true? (Choose three.)

A. The local system sends a series of BFD Echo packets, and the remote system loops the packets back through its forwarding channel. B. If the local system receives several consecutive Echo packets, it advertises a session Down event. C. The echo function can work together with the asynchronous or demand detection mode. D. The echo function can take the place of fault detection by sending BFD control packets.

Which of the following statements about VLSM characteristics are true? (Choose two.)

A. VLSM supports both IPv4 and IPv6. B. VLSM supports overlapped address ranges. C. VLSM provides more proper route summarization information in the routing table. D. VLSM allows a subnet to be divided into smaller subnets.

Which of the following statements about the BFD demand mode are true? (Choose two.)

A. The local system periodically sends BFD control packets, and the remote system detects the BFD control packets sent from the local system. B. The local system detects the BFD control packets sent by itself. C. If one system does not receive any BFD packets from its peer within a detection period, it advertises a session Down event. D. Each system confirms its connections with other systems in a particular method. After a BFD session is set up, BFD control packets are no longer sent.
