Option C. Cisco FMC (Firepower Management Center) communicates with Cisco FTD (Firepower Threat Defense) devices using a management channel established during the registration process. This channel uses a default TCP port (8305) for SFTunnel, which is a secure transport mechanism for FMC-to-FTD communication. If the default port (e.g., 8305) conflicts with other applications on your network, you need to: > Manually update the port on both Cisco FMC and each FTD device. > There is no automatic push or sync of the new port from FMC to FTD. > For me option A is not correct since FMC cannot push this change, because the port is used to establish the connection in the first place.
C. Manually change the management port on Cisco FMC and all managed Cisco FTD devices.
The answer is C. However if you overthink it it could also be A. however in the form the question is asked it should be C. Cisco FMC has the ability to push configuration changes to managed Cisco FTD devices automatically, so changing the management port on the FMC can be propagated to all managed FTD devices without the need for manual intervention on each device. This can be done through the use of FlexConfigs or the Configuration Deployments feature in the FMC. FlexConfigs allow for the execution of custom commands on managed devices, including configuration changes. The FMC can be configured to push a FlexConfig that changes the management port on all managed FTD devices at once.
