Router A has an IP route entry with a purposeful CIDR block of 10001/32 and an outgoing interface of GigabitEthernetO/0/1. Now add the following configuration: acd number 2000 rule 10 permit source1001.10#traffic classifier test if-match acl 2000 # traffic behavior test remarkdscp cs3#traffic policy test classifier test behavior test# interfaceGigabitftherneto/0/1 ip address 1001212552552550 traffic-policy test outbound#assuming router A received a destination IP of 10001 Of packets, the following statements are correct:

A. If the data packet source lIP address is 1001.2, it can be forwarded with the DSCP field marked CS3

B. If the packet source IP address is 1001.1, it can be forwarded while the DSCP field is marked as CS3

C. If the packet source IP address is 1001.2, it cannot be forwarded

D. If the packet source IP address is 1001.2, it can be forwarded while the DSCP field remains unchanged
