How many interfaces per bridge group does an ASA bridge group deployment support?

How many interfaces per bridge group does an ASA bridge group deployment support?
A . up to 2
B . up to 4
C . up to 8
D . up to 16

Answer: B

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 bridgeCgroup (inside, outside, DMZ1, DMZ2)
