单项选择题You work as a network technician at Company.com， study the exhibit provided. You are implementing this QoS configuration to improve the bandwidth guarantees for traffic towards two servers， one with the IP address 5.5.5.5 and the other with the IP address 5.5.5.4. Even after the configuration is applied， performance does not seem to improve. Which will be the most likely cause of this problem？（）

A.The policy map mark has been applied on a half-duplex Ethernet interface；This is not supported.
B.The policy map queue is configured on the wrong interface； it is applied on the Serial interface whereas traffic is going over the tunnel interface.

多项选择题Refer to the exhibit. According to the output of the command show tag-switching forwarding-table, which four of these statements are true?（）

A.Packets to the IP address 10.10.10.5/32 will be tagged with "17" toward the next hop.
B.Label "19" will be advertised to MPLS neighbors so that they can use this label to reach the IP address 10.10.10.6/32.
C.IP address 10.10.10.4/32 is directly connected to the neighbor router on serial 3/0.
D.Packets arriving with label "17" will be forwarded without any label toward serial 4/0.
E.Packets arriving with label "20" will be forwarded with label "21" after label-swapping.
F.Label "20" is advertised to MPLS neighbors so that they can use this information to reach the prefix 10.10.10.8/32.
