The correct sequence of actions for configuring a multi-instance environment for high availability on a Cisco Firepower 4100 appliance is as follows:

Add a resource profile for container instances. A resource profile defines the CPU, RAM, and disk space allocation for each container instance.You can create multiple resource profiles with different resource settings and assign them to different container instances1.

Add a MAC pool prefix and view the MAC address for the container instance interfaces. A MAC pool prefix is a 24-bit prefix that is used to generate MAC addresses for the container instance interfaces. You can specify a custom MAC pool prefix or use the default one.You can also view the MAC addresses that are assigned to each container instance interface1.

Configure interfaces. You need to configure the physical interfaces, EtherChannels, and VLAN subinterfaces that will be used by the container instances.You can also configure shared interfaces that can be used by multiple container instances on the same security module/engine1.

Add a Standalone Firepower Threat Defense for Cisco Secure Firewall Management Center. You need to add a logical device that runs a standalone Firepower ThreatDefense (FTD) application instance and register it with the Cisco Secure Firewall Management Center (FMC).This logical device will act as the management interface for the container instances1.

Add a high-availability pair. You need to add another logical device that runs a standalone FTD application instance and register it with the FMC as well. Then, you need to configure high availability (HA) between the two standalone FTD logical devices.This will enable HA for the container instances that are associated with them1.

The Threat Defense device cannot change its firewall mode while it has an active manager configuration. After unregistering the device from Management Center, the engineer must execute configure manager delete to remove the manager association and place the device in No Manager Mode. The engineer can then execute configure firewall transparent to change the operating mode. Changing firewall modes clears the device configuration because routed-mode and transparent-mode interface configurations are incompatible. After completing the conversion, the engineer must configure the Management Center association again with configure manager add and register the device. Options A and B are not valid Threat Defense CLI commands. Option D performs the actual mode conversion, but it is not the first required CLI command while the manager association remains configured.

A passive interface is specifically designed to monitor copied network traffic received from a switch SPAN or mirror port. Because the Secure Firewall Threat Defense device is not physically placed in the traffic path, it receives a copy of the packets for inspection but does not retransmit them. This provides network and intrusion visibility without affecting production traffic. The trade-off is that a passive deployment cannot directly block, shape, or modify the monitored traffic because the original packets continue through the switch independently. An inline deployment, by comparison, places paired interfaces directly in the forwarding path and can drop malicious traffic. Routed and transparent describe firewall forwarding modes and are not the appropriate SPAN-based IPS interface type. Therefore, a SPAN-port monitoring deployment requires a passive interface.

Cisco Secure Cloud Analytics ingests network flows and traffic telemetry, such as NetFlow and cloud flow logs, and applies behavioral modeling to that information. It establishes a baseline of normal activity for entities such as hosts, users, and workloads. New activity is compared with the baseline to identify anomalies, suspicious communication patterns, lateral movement, command-and-control traffic, and potential data exfiltration. The platform does not merely forward or archive the collected information. Although its analytics may incorporate statistical methods and machine learning, Cisco specifically describes the solution as using entity and behavioral modeling. This allows it to detect threats based on how an entity acts over time, including previously unknown threats that would not necessarily match a conventional signature. Cisco Secure Cloud Analytics

A correlation policy is a feature that allows you to respond in real time to threats or specific conditions on your network, using correlation rules. A correlation rule can trigger when the system generates a specific type of event, or when your network traffic deviates from its normal profile1. When a correlation rule triggers, the system generates a correlation event and can also launch a response, such as sending an alert, blocking an IP address, or scanning a host1.

In this case, the security engineer can configure a correlation rule that triggers when the system detects five or more connections from external sources within 2 minutes. The engineer can also configure a response that sends an alert to the FMC or an email recipient when this condition is triggered. The engineer can then create a correlation policy that includes this rule and activate it on the FTD device1.

The other options are incorrect because:

An application detector is a feature that allows you to detect web applications, clients, and application protocols based on patterns in network traffic. An application detector does not generate alerts based on the number of connections from external sources2.

An access control policy is a feature that allows you to control traffic flow through your network and inspect traffic for intrusions, malware, and files. An access control policy does not generate alerts based on the number of connections from external sources3.

An intrusion policy is a feature that allows you to detect and prevent malicious network activity using Snort rules. An intrusion policy does not generate alerts based on the number of connections from external sources4.

Integrated Routing and Bridging allows a Secure Firewall device operating in routed mode to contain bridge groups while also supporting routed interfaces. Multiple physical or logical interfaces can become members of one bridge group, placing them in the same Layer 2 broadcast domain, VLAN, and IP subnet. A Bridge Virtual Interface represents that bridge group at Layer 3 and functions as its gateway, permitting communication between the bridged network and routed interfaces or other bridge groups, subject to security policy. This can remove the need for an additional external Layer 2 switch when suitable firewall interfaces are available. IRB does not itself provide high availability, security-context separation, or Cisco Talos threat-intelligence updates. Those capabilities are implemented through separate features. Therefore, allowing multiple interfaces to participate in the same VLAN is the stated IRB benefit. Cisco IRB documentation
