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

If an engineer receives a 403: Forbidden error when attempting to download a packet capture file from Cisco Secure Firewall Management Center (FMC), the issue is likely due to HTTPS not being enabled in the device platform policy. To resolve this issue, the engineer must enable HTTPS in the platform policy.

Steps:

In FMC, navigate toPolicies > Device Management > Platform Settings.

Edit the relevant platform policy.

Enable HTTPS for the device.

Deploy the changes to the FTD device.

This ensures that the FMC and FTD device can securely transfer the packet capture file over HTTPS, resolving the 403 error.

Cisco Secure Firewall Threat Defense supports IPsec encryption between the failover links of a high-availability pair. During HA configuration, the engineer enables encryption and selects the appropriate Key Generation method for IPsec. This protects failover and stateful synchronization data exchanged between the active and standby units. An SSL remote-access VPN is designed for user-to-network connectivity and is not used to protect an internal HA link. SSL is also not the documented encryption mechanism for Threat Defense failover synchronization. Clearing a commit queue does not encrypt or otherwise protect synchronized state information. Cisco’s HA configuration procedure explicitly instructs administrators to enable the encryption option and choose the Key Generation method for IPsec encryption between the failover links. Therefore, option B directly implements the required synchronization-protection mechanism. Cisco Secure Firewall high-availability configuration

Conditions

In order to create an HA between 2 FTD devices, these conditions must be met:

Same model

Same version (this applies to FXOS and to FTD - (major (first number), minor (second number), and maintenance (third number) must be equal))

Same number of interfaces

Same type of interfaces

Both devices as part of same group/domain in FMC

Have identical Network Time Protocol (NTP) configuration

Be fully deployed on the FMC without uncommitted changes

Be in the same firewall mode: routed or transparent.

Note that this must be checked on both FTD devices and FMC GUI since there have been cases where the FTDs had the same mode, but FMC does not reflect this.

Does not have DHCP/Point-to-Point Protocol over Ethernet (PPPoE) configured in any of the interface

Different hostname (Fully Qualified Domain Name (FQDN)) for both chassis. In order to check the chassis hostname navigate to FTD CLI and run this command

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.

The Cisco Threat Response browser plugin provides contextual investigation capabilities that can be launched from Secure Firewall Management Center. It allows an administrator to investigate an observable, such as a suspicious IP address, against Cisco threat-intelligence and integrated security sources without manually transferring the value to another interface. Secure Network Analytics analyzes network telemetry and behavior but is not the browser-based lookup mechanism described. Cisco ISE supplies identity, authorization, and network-access context, while Secure Endpoint provides endpoint telemetry and file or process investigation. Neither is the direct web-page investigation tool requested. Cisco documentation describes contextual cross-launch functionality for looking up suspicious source addresses in Cisco or third-party cloud-hosted intelligence services. Therefore, the Threat Response browser plugin is the correct selection. Cisco event investigation using web resources

When connectivity issues are detected between Cisco Secure Firewall Management Center (FMC) and Cisco Secure Firewall Threat Defense (FTD) devices, and initial troubleshooting indicates that heartbeats and events are not being received, the engineer can run the following commands to resolve the issue by re-establishing secure channels and checking process statuses:

manage_procs.pl:This script is used to manage and restart processes on the FTD device. Running this script can help restart any malfunctioning processes and re-establish connectivity between the FMC and FTD.

sudo stats_unified.pl:This command provides detailed statistics and status of the unified system processes. It helps in diagnosing and resolving issues related to the secure channel and event reporting.

Steps:

Access the FTD CLI.

Run the commandmanage_procs.plto restart processes.

Run the commandsudo stats_unified.plto gather detailed process statistics and verify the status.

These commands help resolve connectivity issues by ensuring that all necessary processes are running correctly and secure channels are re-established.

Traditionally, a firewall is a routed hop and acts as a default gateway for hosts that connect to one of its screened subnets. A transparent firewall, on the other hand, is a Layer 2 firewall that acts like a “bump in the wire,” or a “stealth firewall,” and is not seen as a router hop to connected devices. However, like any other firewall, access control between interfaces is controlled, and all of the usual firewall checks are in place. Layer 2 connectivity is achieved by using a " bridge group " where you group together the inside and outside interfaces for a network, and the ASA uses bridging techniques to pass traffic between the interfaces. Each bridge group includes a Bridge Virtual Interface (BVI) to which you assign an IP address on the network. You can have multiple bridge groups for multiple networks. In transparent mode, these bridge groups cannot communicate with each other.https://www.cisco.com/c/en/us/td/docs/security/asa/asa97/configuration/general/asa-97-general-config/intro-fw.html
