Probably Answer is incomplete…
My guess: When setting up management network using elastic network interfaces. To ensure failover capabilities, consider using a secondary private IP for incoming traffic on an elastic network interface.

ans> B
To ensure failover capabilities, consider using a secondary private IP for incoming traffic on an elastic
network interface. In the event of an instance failure, you can move the interface and/or secondary private
IP address to a standby instance
B: secondary private IP for incoming traffic
B is the right answer.
See http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-eni.html#creating-a-management-network
To ensure failover capabilities, consider using a secondary private IPv4 for incoming traffic on a network interface. In the event of an instance failure, you can move the interface and/or secondary private IPv4 address to a standby instance.
B.
secondary private IP
The question does not indicate if it is private or public network/interface.
So the response should also be generic.
D sounds more appropriate
B
Have been reading the responses from “networkmanagers”. Many of users in the following posts have suggested to ignore these response.
Better to verify once before considering.
B “secondary private IP” is the correct answer… because it’s the only answer that makes sense. The question is confusing because there are FAR better ways of implementing failover… but it’s the only answer that makes sense.
“To ensure failover capabilities, consider using a _____ for incoming traffic on a network
interface”.
A. primary public IP <== INCORRECT… using a "primary public IP" is the norm and has no bearing on failover.
B. secondary private IP <== CORRECT… bizarre but correct… You COULD set up failover as follows (for example): (1) set up a "secondary private IP" on your host, (2) associate the "incoming traffic" EIP with that "secondary private IP", (3) Run a "failover" on a "failover host" which will transfers the secondary ENI to itself should the primary host's primary IP go down.
C. secondary public IP <== INCORRECT. Adding a secondary public IP does nothing for failover.
D. add on secondary IP <== INCORRECT. I'm not even sure it's possible to just add a secondary IP address (without a secondary ENI), but if it is possible it won't help failover because the EPI won't be associated with it.
