High availability (HA) is a network design and implementation strategy that provides redundancy and automatic failover in the event of a hardware or software failure. Cisco Firepower Threat Defense (FTD) provides High Availability (HA) as a feature to ensure network traffic continues to flow in the event of a device failure.

To ensure High Availability (HA) between two Cisco FTD devices, there are certain conditions that must be met. These include:

  1. The units must be the same model: To ensure that the failover process works correctly, it is necessary to have the same model of Cisco FTD devices. This ensures that the primary and secondary devices have the same features and hardware capabilities, making the failover process smoother and more efficient. If the two devices are not of the same model, then the failover may not work as expected, resulting in network downtime.

  2. The units must be the same version: To ensure proper failover, it is necessary to have the same version of the Cisco FTD software installed on both devices. If there is a version mismatch between the primary and secondary devices, then the failover may not work as expected, which can result in network downtime. It is important to keep the software versions up to date to ensure that all security features and bug fixes are available.

Therefore, the correct answers to the question are A. The units must be the same version, and E. The units must be the same model.

Option B is incorrect because devices must be part of the same group, not different groups. Option C is incorrect because the units must be the same model, not different models. Option D is incorrect because the units can be configured in either routed mode or transparent mode for high availability to function correctly.
