Explanation
Each of the ASAs interfaces need to be grouped into one or more bridge groups. Each of these groups acts as an independent transparent firewall. It is not possible for one bridge group to communicate with another bridge group without assistance from an external router.
As of 8.4(1) upto 8 bridge groups are supported with 2-4 interface in each group. Prior to this only one bridge group was supported and only 2 interfaces.
Up to 4 interfaces are permitted per bridge-group (inside, outside, DMZ1, DMZ2)

You can configure discovery rules to tailor the discovery of host and application data to your needs.
The Firepower System can use data from NetFlow exporters to generate connection and discovery events, and to add host and application data to the network map.
A network analysis policy governs how traffic is decoded and preprocessed so it can be further evaluated, especially for anomalous traffic that might signal an intrusion attempt -> Answer D is not correct.
