A.When sending a data packet whose destination address is 4.4.4.4, send it directly without labeling.

B.When the router receives a packet with a label of 1024, it will change the label to 1027 and send it.

C.When sending a data packet whose destination address is 3.3.3.3, label it with 1026 and send it.

D.When sending a data packet whose destination address is 2.2.2.2, send it directly without labeling.

A.Multiple stack systems after splitting will have the same IP address and MAC address. To avoid causing network failures, the stack will perform MAD detection.
The party that fails the MAD detection competition will close all physical ports except reserved ports.

B.If the primary switch is in two stacking systems after the stack is split, the stack system where the original master switch is located updates the topology, reassigns the primary switch, and the original standby switch is promoted to the primary switch in the new stack system, and a new standby switch is elected at the same time

C.If the master and slave switches are still in the same stack system after the stack splits, the slave switch separated from the original master and slave switches will re-elect the master and slave switch due to protocol packet timeout.

D.After the stack is split, the MAC addresses of the two stack systems will change immediately.

A.AES

B.DES

C.MD5

D.3DES

A.Routing policies mainly control the introduction, publishing and reception of routing information.

B.Policy routing mainly controls the introduction, publication and reception of routing information.

C.Policy routing mainly controls the forwarding of packets, that is, packets can be forwarded without following the routing table.

D.Routing policies mainly control the forwarding of packets, that is, packets may be forwarded without following the routing table.

A.Dead time interval is consistent

B.Router IDs are the same

C.The Hello time interval is the same

D.The mask is consistent

E.Dir-priority consistent

F.The MTU size is the same
