An engineer must replace a Cisco Secure Firewall high-availability device due to a failure. When the replacement device arrives, the engineer must separate the high-availability pair from Cisco Secure Firewall Management Center. Which action must the engineer take first to restore high availability?
Answer(s): A
Refer to the exhibit. A Cisco Secure Firewall Threat Defense (FTD) device is deployed in inline mode with an inline set. The network engineer wants router R2 to remove the directly connected route 192.168.1.0/24 from its routing table when the cable between router R1 and the Secure FTD device is disconnected. Which action must the engineer take?
Refer to the exhibit. A company is deploying a pair of Cisco Secure Firewall Threat Defense devices named FTD1 and FTD2. FTD1 and FTD2 have been configured as an active/standby pair with a failover link but without a stateful link. What must be implemented next to ensure that users on the internal network still communicate with outside devices if FTD1 fails?
An engineer is deploying a Cisco ASA Secure Firewall module. The engineer must be able to examine traffic without impacting the network, and the ASA has been deployed with a single context. Which ASA SecureFirewall module deployment mode must be implemented to meet the requirements?
Answer(s): B
In this scenario, the engineer's requirement is to inspect traffic without impacting the network. To meet this, the passive monitor-only mode is an appropriate choice:Transparent Mode: In this mode, the Cisco ASA acts as a "bump in the wire," making it effectively invisible to the network. This mode does not require IP addresses on the interfaces, allowing it to inspect traffic without altering or routing it, making it ideal for passive monitoring scenarios.Passive Monitor-Only Mode: This mode is specifically designed to allow traffic inspection without interference. Traffic flows through the device, allowing it to inspect packets but without enforcing policies or disrupting packet flow, which is crucial to meet the requirement of "no network impact." Single Context Requirement: The setup specifies a single context, which simplifies the deployment by using one consistent inspection policy across the traffic.
An engineer is setting up a new Cisco Secure Firewall Threat Defense appliance to replace the current firewall. The company requests that inline sets be used and that when one interface in an inline set goes down, the second interface in the inline set goes down. What must the engineer configure to meet the deployment requirements?
In Cisco Secure Firewall Threat Defense deployments, propagate link state is a feature designed to manage interface behavior in inline sets. When inline sets are used, the network often requires that both interfaces in the set behave consistently; if one interface in the pair goes down, the other should automatically go down to prevent asymmetric routing or network issues. The Propagate Link State setting ensures that when one interface in an inline set experiences a failure, the paired interface automatically reflects that down status. This is critical in setups where symmetry and failover are essential, especially in high-availability or redundant network designs.
