What is the result when two users modify a VPN policy at the same lime on a Cisco Secure Firewall Management Center managed device?
In Cisco Secure Firewall Management Center (FMC), when two users attempt to modify a VPN policy simultaneously, the system implements a locking mechanism to prevent conflicts. The first user who selects edit on the policy locks the configuration, preventing other users from making changes until the lock is released.
Steps:
When the first user selects edit on the VPN policy, FMC locks the policy for editing.
The lock ensures that only the first user can make changes.
Once the first user saves or cancels their changes, the lock is released.
Other users can then edit the policy.
This locking mechanism ensures that configuration conflicts are avoided and only one set of changes is applied at a time.
An engineer must change the mode of a Cisco Secure Firewall Threat Defense (FTD) firewall in the Cisco Secure Firewall Management Center (FMC) inventory. The engineer must take these actions:
* Register Secure FTD with Secure FMC.
* Change the firewall mode.
* Deregister the Secure FTD device from Secure FMC.
How must the engineer take FTD take the actions?
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.
An administrator must fix a network problem whereby traffic from the inside network to a webserver is not getting through an instance of Cisco Secure Firewall Threat Defense. Which command must the administrator use to capture packets to the webserver that are dropped by Secure Firewall Throat Defense and resold the issue?
To capture packets that are dropped by Cisco Secure Firewall Threat Defense (FTD) and troubleshoot the issue of traffic from the inside network to a webserver not getting through, the administrator should use the command to capture packets dropped by the accelerated security path (ASP) engine. The correct command is:
capture CAP type asp-drop all headers-only
This command captures all packets dropped by the ASP engine, which includes packets that are being blocked by access control policies, NAT issues, or other security checks.
Steps:
Access the FTD CLI.
Run the command capture CAP type asp-drop all headers-only to capture dropped packets.
Analyze the captured data to identify the cause of the drops.
This command provides detailed information on why packets are being dropped, helping the administrator resolve the issue.
A network engineer detects a connectivity issue between Cisco Secure Firewall Management Centre and Cisco Secure Firewall Threat Defense Initial troubleshooting indicates that heartbeats and events not being received. The engineer re-establishes the secure channels between both peers Which two commands must the engineer run to resolve the issue? (Choose two.)
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 command manage_procs.pl to restart processes.
Run the command sudo stats_unified.pl to 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.
A network administrator is deploying a new Cisco Secure Firewall Threat Defense (FTD) firewall After Cisco Secure FTD is deployed, inside clients nave intermittent connectivity to each other. When ... the packet capture on the Secure FTD firewall, the administrator sees that Secure FID is responding to all the AW requests on the inside network. Which action must the network administrator e to resolve the issue''
If inside clients have intermittent connectivity issues and the Cisco Secure FTD is responding to all ARP requests on the inside network, it indicates that there may be an incorrect proxy ARP configuration in the NAT policy. Proxy ARP can cause the FTD to respond to ARP requests on behalf of other devices, leading to connectivity issues.
Steps to resolve:
Review the NAT policy on the FTD to identify any incorrect proxy ARP configurations.
Disable the proxy ARP setting for the relevant NAT rules that are causing the issue.
This ensures that the FTD only responds to ARP requests as needed, preventing it from interfering with normal ARP traffic on the inside network.
