How can you configure a second export destination IP address 192.168.10.1
Configure terminal
Ip flow-export destination 192.168.10.1 9991
Ip flow-export version 9
A. Specify a different TCP port
B. Specify a different UDP port
C. Specify a VRF
D. Configure a version 5 flow-export to the same destination
E. Specify a different flow ID
it’s definitly b
SUMMARY STEPS
1. enable
2. configure terminal
3. ip flow-export destination {ip-address | hostname} udp-port

4. Repeat Step 3 once to configure a second NetFlow export destination.

I gotta agree with Ayman, if you use a VRF to start a new flow, it will be a totally different flow, just like taking a different physical router and setting up a flow. VRF will separate the routing, FIB, ARP tables. I don’t think that is what Cisco is asking for in the question.
Answer: B
The same ip address destination is not allow.
Ayman, in the documentation with you shared has the information.
The following example shows how to configure the networking device to export the NetFlow cache entry to two different UDP ports on the same destination system:
Router(config)# ip flow-export destination 10.42.42.1 9991
Router(config)# ip flow-export destination 10.42.42.1 9992
%Warning: Second destination address is the same as previous address 10.42.42.1
The best anwser is B, in VRF mode.
Best Answer C, Yes
It displays the warning but it doesn’t prevent you from configuring it nor working. Correct answer for me is B
It is B no C
The most common use of the multiple-destination feature is to send the NetFlow cache entries to two different destinations for redundancy. Therefore, in most cases the second destination IP address is not the same as the first IP address. The port numbers can be the same when you are configuring two unique destination IP addresses. If you want to configure both instances of the command to use the same destination IP address, you must use unique port numbers. You receive a warning message when you configure the two instances of the command with the same IP address. The warning message is, “%Warning: Second destination address is the same as previous address “.
