A. B. C. D.D.
https://www.cisco.com/c/en/us/td/docs/security/firepower/640/configuration/guide/fpmc-config-guide-v64/In Cisco Firepower, the Advanced tab under Inline Set Properties allows for the configuration of advanced options for an inline set, which is a grouping of interfaces that operate in inline mode.
The question specifically asks which option on this tab allows interfaces to emulate a passive interface. A passive interface is one that does not actively participate in routing protocols but still listens to routing updates.
The correct answer is B. TAP mode. TAP mode is an inline mode in which the device monitors traffic on a specified interface without actively participating in the traffic flow. It allows the device to act as a "passive listener" to the traffic, without actually forwarding or blocking any packets.
Option A, transparent inline mode, is an inline mode in which the device is transparent to the traffic flow, meaning that packets pass through the device without being modified.
Option C, strict TCP enforcement, is a feature that enforces TCP protocol compliance, including monitoring for out-of-order packets, retransmissions, and other TCP anomalies.
Option D, propagate link state, is a feature that allows the device to propagate link state information between connected devices in order to maintain network topology information.
In summary, the correct answer is B. TAP mode, as it allows interfaces to emulate a passive interface by monitoring traffic without actively participating in the traffic flow.
