High Availability Deployment Types

AB.

The two deployment types that support high availability in Cisco Firepower are clustered deployment and intra-chassis multi-instance deployment.

1. Clustered deployment: In a clustered deployment, multiple Firepower devices work together as a single logical unit to provide high availability. Each device in the cluster shares information about the network and security policies, and if one device fails, the others in the cluster can take over its functions. This provides automatic failover and helps ensure that network security remains intact even in the event of a device failure.

2. Intra-chassis multi-instance deployment: In an intra-chassis multi-instance deployment, a single Firepower device is configured to support multiple independent security contexts, each of which can be used to provide network security for a different part of the network. This type of deployment can be useful in situations where high availability is important, such as in data centers or large enterprise networks. If one security context fails, the others can continue to provide network security, helping to ensure that the network remains protected.

Transparent and routed deployments, on the other hand, do not support high availability. In a transparent deployment, the Firepower device is placed in the network in a way that is invisible to other devices, and it cannot provide high availability on its own. In a routed deployment, the Firepower device is used to route traffic between different parts of the network, but it does not have the ability to provide high availability on its own.

Finally, a virtual appliance in a public cloud deployment could support high availability if configured appropriately, but it is not listed as an option in the exam question.
