300-710 Cisco Securing Networks with Cisco Firepower (300-710 SNCF) v1.2 Free Practice Exam Questions (2026 Updated)

To change the mode of a Cisco Secure Firewall Threat Defense (FTD) device in the Cisco Secure Firewall Management Center (FMC) inventory, the engineer must follow these steps:

Register the Secure FTD with Secure FMC.

Change the firewall mode.

Deregister the Secure FTD device from Secure FMC.

To perform these actions, accessing the Secure FTD CLI from the console port is necessary. This allows the engineer to execute the required commands to change the firewall mode and manage the registration status of the FTD device.

Steps:

Connect to the Secure FTD device via the console port.

Access the CLI and execute the command to change the firewall mode (configure firewall-mode).

Deregister the device from FMC if needed.

Register or re-register the device with FMC as required.

The Encrypted Visibility Engine (EVE) in Cisco Secure Firewall Management Center is enabled under the SSL tab of an access control policy. EVE provides visibility into encrypted traffic, allowing the firewall to detect threats even when traffic is encrypted.

Steps to enable EVE:

Navigate to the access control policy in FMC.

Go to theSSLtab.

Enable Encrypted Visibility Engine (EVE) to analyze encrypted traffic.

This configuration helps in identifying and mitigating threats within encrypted traffic without the need for full decryption.

Disseminate: The dissemination phase publishes the results of the investigation or threat hunt. This information is disseminated with a focus on the receivers of the information. At the tactical level, this information feeds back into the beginning of the F3EAD model, Find. Figure 3 illustrates the F3EAD model.

The Untrusted reputation level represents URLs associated with malicious, undesirable, or demonstrably unsafe behavior and is therefore the appropriate selection for the access control rule. Questionable applies to URLs that exhibit suspicious characteristics but lack sufficient evidence to be classified as definitively malicious. Neutral identifies sites without a strong positive or negative reputation, while Favorable indicates generally acceptable sites with a positive reputation history. Secure Firewall Management Center combines URL categories with reputation values to provide more precise web-control decisions. Selecting Untrusted enables the rule to match the highest-risk URLs covered by the requirement without unnecessarily treating merely unknown or neutral sites as confirmed threats. Cisco documents URL reputation as the risk component used with URL categories in category-and-reputation-based filtering. Cisco Secure Firewall URL filtering

In a failover configuration with Cisco Secure Firewall Threat Defense (FTD) devices, ensuring that users on the internal network can continue to communicate with outside devices if the primary device (FTD1) fails requires the implementation of a stateful failover link. The stateful failover link allows the secondary device (FTD2) to maintain session information and state data, ensuring seamless failover and minimizing disruptions.

Steps to implement a stateful failover link:

Physically connect a stateful failover link between FTD1 and FTD2.

Configure the stateful failover link in the FMC.

Ensure that both devices are properly synchronized and that stateful failover is enabled.

Deploy the changes to both FTD devices.

By configuring a stateful link, the secondary FTD can take over active sessions without requiring users to re-establish their connections, thus ensuring continuous communication.

Individual intrusion rules do not support direct time-range conditions or scheduled activation triggers. Instead, the administrator creates a time-range object and uses it as a condition in an access control rule. The required intrusion policy is then associated with that access control rule. During the specified time range, matching traffic invokes the intrusion policy and its enabled intrusion rules; outside the range, the access control rule does not match. Multiple access control rules can be created when different intrusion policies or protection levels are needed at different times. Secure Firewall Management Center does not require an external scheduled task to enable and disable individual intrusion rules. Cisco documents time-range objects as the mechanism for making supported policies apply only during defined periods. Therefore, time-based access control rules are the correct implementation.

Secure Firewall access control evaluates a connection using the destination’s real, untranslated address. For an inbound static NAT connection, the Internet client sends traffic to the mapped public address, but the firewall performs NAT untranslation and evaluates the access control rule against the internal server address. Consequently, a rule containing only the public address will not match as intended. The administrator must replace that public destination with the web server’s internal IP address while retaining the required TCP port and appropriate Allow action. Changing the action to Trust does not correct an address-matching error and would also bypass additional inspection. Disabling intrusion inspection is unrelated, and translating the client’s source address is unnecessary for ordinary inbound static NAT. Therefore, the access control rule must reference the internal, real server address. Cisco NAT and real-address documentation
