A.You can join the interface group member through the channel aggregation enabled by the following
command:
Interface Gigabitethernet0/0/1 shutdown
Interface Gigabitethernet0/0/1 trunkport Gigabitethernet0/0/ interface Gigabitethernet0/0/1 undo
shutdown

B.You can avoid the Eth-Trunk interface due to physical path caused by the following commands.

C.You can use the following command to configure the row source chain in the enabled route aggregation.
IP: interface eth-trunk 1 address line share into the load
Load-balance src-dst-ip

D.: You can use the following command to divide the interface into the chain aggregation in the enabled
route aggregation.
Interface Gigabitethemnet0/0/0
Debug
Interface Gigabitethernet0/0/1
Undo eth-trunk 1
Interface Gigabitetheret0/0/
Undo shutdown

A.All LSAs, except Grace LSAs, can be filtered based on interfaces in the inbound and outbound directions.

B.In a NSSA, when external routes are imported to the OSPF router and LSAs are advertised to its neighbors, LSA filtering can be performed on the ASBR or ABR.

C.The filtering of Type 3 LSAs needs to be configured on ABRs in OSPF.

D.When routes are calculated based on the LSDB, the filter-policy import command can be executed to filter routes. This filtering mode affects only the addition of routes in the routing table, and has no impact on the OSPF LSDB.

A.There is no route on the destination network segment on R1 10.0.2.2/32.

B.There is a route on the destination network segment on R1 10.0.3.3/32.

C.There is a route on the destination network segment on R1 10.0.2.2/32.

D.There is no route on the destination network segment on R1 10.0.3.3/32.

A.IPSG checks the source IP addresses and source MAC addresses of IP packets, and DAI checks only the mapping between IP addresses and MAC addresses.

B.DAI binding entries cannot be manually configured.

C.URPF can be used to defend against DDoS attacks from forged sources.

D.IPSG checks IP packets to defend against attacks using spoofed source IP addresses, and DAI checks ARP packets to filter out attack sources.

A.Error

B.Correct
