Selected Answer: D
Passive mode, because in passive mode FTD will not sit physically inserted into the path. Copy of traffic will be sent to IPS with the help of SPAN/RSPAN/ERSPAN technology. So, we can avoid both hardware failure and Snort engine failure as well.

I feel the "any type of failure" is the hint. if it's just software - sure that's B. This one feels like it's talking about even hardware failure.

Selected Answer: A
For certain interface modules on the Firepower 9300, 4100, and 2100 series (see Requirements and Prerequisites for Inline Sets), you can enable the Hardware Bypass feature. Hardware Bypass ensures that traffic continues to flow between an inline interface pair during a power outage. This feature can be used to maintain network connectivity in the case of software or hardware failures.

Of the options given, "A" is the best choice. Even if a Layer 1 issue occurs traffic would continue to flow, with some interruption. If a Layer 1 occurs in any of the other options, traffice would cease. https://www.cisco.com/c/en/us/td/docs/security/firepower/4100/hw/guide/b_install_guide_4100/overview.html#:~:text=When%20the%20appliance%20switches%20from%20normal%20operation%20to%20hardware%20bypass%20or%20from%20hardware%20bypass%20back%20to%20normal%20operation%2C%20traffic%20may%20be%20interrupted%20for%20several%20seconds.
