A. True
B. False

Question 52

A. True
B. False

Question 54
Which of the following statements about link aggregation are true? (Choose three.)
A. Link aggregation binds a group of physical interfaces together as a logical interface to increase the bandwidth and reliability.
B. Link aggregation complies with IEEE 802.3az.
C. The logical link formed by bundling multiple physical links together is called a link aggregation group (LAG) or a trunk.
D. Active and inactive interfaces exist in link aggregation. Active interfaces forward data, whereas inactive interfaces do not.

Question 55
When links are switched in a Smart Link group, which of the following mechanisms can be used to refresh MAC and ARP entries? (Choose three.)
A. MAC and ARP entries are refreshed automatically with respect to traffic.
B. The Smart Link group uses a new link to send Flush packets.
C. MAC entries are refreshed after the aging time expires.
D. ARP entries are refreshed after the aging time expires

Question 56
Which of the following statements about the BFD asynchronous mode are true? (Choose two.)
A. The local system regularly 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.
