Exam 300-710 topic 1 question 43 discussion

C and D are the wrong answers. Must be B and E. Cisco FMC config guide v 6.2 states that: Bridge Group Guidelines (Transparent and Routed Mode): You can create up to 250 bridge groups, with 64 interfaces per bridge group. Each directly-connected network must be on the same subnet.

"Bridge groups are supported in both transparent and routed firewall mode" "Each directly-connected network must be on the same subnet." https://www.cisco.com/c/en/us/td/docs/security/firepower/640/configuration/guide/fpmc-config-guide-v64/transparent_or_routed_firewall_mode_for_firepower_threat_defense.html

The anser Highlighted are C and D, and should be B and E.

B & E -- https://www.cisco.com/c/en/us/td/docs/security/firepower/610/configuration/guide/fpmc-config-guide-v61/fpmc-config-guide-v61_chapter_01110000.pdf Bidirectional Forwarding Detection (BFD) echo packets are not allowed through the FTD when using bridge group members. If there are two neighbors on either side of the FTD running BFD, then the FTD will drop BFD echo packets because they have the same source and destination IP address and appear to be part of a LAND attack.

Correct answer is: B and E

C is correct as per below Cisco config guide "About Bridge Groups". However, Bridge group traffic can be routed to other bridge groups or routed interfaces. You can choose to isolate bridge group traffic by not assigning a name to the BVI interface for the bridge group. If you name the BVI, then the BVI participates in routing like any other regular interface. https://www.cisco.com/c/en/us/td/docs/security/firepower/610/configuration/guide/fpmc-config-guide-v61/fpmc-config-guide-v61_chapter_01110000.pdf

Must be BE

Supported in both modes and must be the same subnet.

Completely wrong answer BVI supported in R and T mode and have to be same subnet as connected network.
