NEW QUESTION # 151
An engineer must investigate a connectivity issue from an endpoint behind a Cisco FTD device and a public DNS server. The endpoint cannot perform name resolution queries. Which action must the engineer perform to troubleshoot the issue by simulating real DNS traffic on the Cisco FTD while verifying the Snarl verdict?
- A. Use the Capture w/Trace wizard in Cisco FMC.
- B. Create a Custom Workflow in Cisco FMC.
- C. Run me system support firewall-engine-debug command from me FTD CLI.
- D. Perform a Snort engine capture using tcpdump from the FTD CLI.
Answer: A
Explanation:
The Capture w/Trace wizard in Cisco FMC allows you to capture packets on an FTD device and trace their path through the Snort engine. This can help you troubleshoot connectivity issues from an endpoint behind an FTD device and a public DNS server, as well as verify the Snort verdict for the DNS traffic. The Capture w
/Trace wizard lets you specify the source and destination IP addresses, ports, and protocols for the packets you want to capture and trace, as well as the FTD device and interface where you want to perform the capture.
You can also apply filters to limit the capture size and duration. After you start the capture, you can ping the DNS server from the endpoint and then view the captured packets and their Snort verdicts in the FMC web interface2.
To use the Capture w/Trace wizard in Cisco FMC, you need to follow these steps2:
In the FMC web interface, navigate to Troubleshooting > Capture/Trace.
Click New Capture.
Choose an FTD device from the Device drop-down list.
Choose an interface from the Interface drop-down list.
Enter the source and destination IP addresses, ports, and protocols for the packets you want to capture and trace. For example, if you want to capture DNS queries from an endpoint with IP address 10.1.1.100 to a DNS server with IP address 8.8.8.8, you can enter these values:
Source IP: 10.1.1.100
Source Port: any
Destination IP: 8.8.8.8
Destination Port: 53
Protocol: UDP
Optionally, apply filters to limit the capture size and duration. For example, you can set the maximum number of packets to capture, the maximum capture file size, or the maximum capture time.
Click Start.
Ping the DNS server from the endpoint and wait for some packets to be captured.
Click Stop to stop the capture.
Click View Capture to see the captured packets and their Snort verdicts.
The other options are incorrect because:
Performing a Snort engine capture using tcpdump from the FTD CLI will not allow you to trace the path of the packets through the Snort engine or verify their Snort verdicts. Tcpdump is a command-line tool that can capture packets on an FTD device, but it does not provide any information about how Snort processes those packets or what actions Snort takes on them2.
Creating a Custom Workflow in Cisco FMC will not help you troubleshoot a connectivity issue from an endpoint behind an FTD device and a public DNS server. A Custom Workflow is a user-defined set of pages that display event data in different formats, such as tables, charts, maps, and so on. A Custom Workflow does not allow you to capture or trace packets on an FTD device3.
Running the system support firewall-engine-debug command from the FTD CLI will not allow you to simulate real DNS traffic on the FTD device or verify the Snort verdict for that traffic. The firewall-engine- debug command is a diagnostic tool that can generate synthetic packets and send them through the Snort engine on an FTD device. The synthetic packets are not real network traffic and do not affect any connections or policies on the FTD device4.

NEW QUESTION # 158
A network engineer must configure an existing firewall to have a NAT configuration. The now configuration must support more than two interlaces per context. The firewall has previously boon operating transparent mode. The Cisco Secure Firewall Throat Defense (FTD) device has been deregistered from Cisco Secure Firewall Management Center (FMC). Which set of configuration actions must the network engineer take next to meet the requirements?
- A. Run the configure firewall routed command from the Secure FTD device CD, and reregister with Secure FMC.
- B. Run the configure manager add routed command from the Secure FTD device CL1, and reregister with Secure FMC.
- C. Run the configure manager add routed command from the Secure FMC CLI. and reregister with Secure FMC.
- D. Run the configure firewall routed command from the Secure FMC CLI. and reregister with Secure FMC.
Answer: A
Explanation:
To support more than two interfaces per context and enable NAT configurations, the firewall must operate in routed mode. Since the firewall was previously in transparent mode, the network engineer needs to change it to routed mode.
Steps:
Access the CLI of the Secure FTD device.
Run the commandconfigure firewall routedto switch the firewall from transparent mode to routed mode.
Reregister the FTD device with the FMC by running theconfigure manager add < FMC_IP > < Registration_Key > command from the FTD device CLI.
This will ensure that the firewall can support the required NAT configurations and more than two interfaces per context.

NEW QUESTION # 169
A network administrator is reviewing a monthly advanced malware risk report and notices a host that Is listed as CnC Connected. Where must the administrator look within Cisco FMC to further determine if this host is infected with malware?
- A. Analysis > Hosts > Host Attributes
- B. Analysts > Files > Malware Events
- C. Analysis > Flies > Network File Trajectory
- D. Analysis > Hosts > indications of Compromise
Answer: D
Explanation:
Explanation
To determine if a host is infected with malware, the network administrator can look at the Indications of Compromise (IOC) feature in Cisco FMC. The IOC feature analyzes network and endpoint data collected by Firepower sensors and AMP for Endpoints connectors, and identifies hosts that exhibit signs of compromise or infection. The IOC feature uses predefined rules based on Cisco Talos intelligence and other sources to detect IOCs on hosts. One of these rules is CnC Connected, which indicates that a host has communicated with a command-and-control (CnC) server that is known to be associated with malware activity2.
To view the IOC information for a host, the network administrator can navigate to Analysis > Hosts > Indications of Compromise in Cisco FMC, and select a host from the table. The IOC Details page will show the IOC events for that host, including the CnC Connected event, along with other information such as severity, timestamp, source, destination, protocol, and rule name. The network administrator can also view more details about each IOC event by clicking on it2.
The other options are incorrect because:
Analysis > Files > Malware Events shows information about files that have been detected as malware by Firepower sensors or AMP for Endpoints connectors. This does not show information about hosts that are infected with malware or have communicated with CnC servers3.
Analysis > Hosts > Host Attributes shows information about hosts that have been discovered by Firepower sensors, such as IP address, MAC address, operating system, applications, users, vulnerabilities, and so on. This does not show information about IOCs or CnC connections on hosts4.
Analysis > Files > Network File Trajectory shows information about files that have traversed your network and have been detected by Firepower sensors or AMP for Endpoints connectors. This allows you to track where a file came from, where it went, and what happened to it along the way. This does not show information about hosts that are infected with malware or have communicated with CnC servers5.
NEW QUESTION # 170

Which configuration change is needed?
- A. The access policy rule must be configured for the action trust.
- B. The intrusion policy must be disabled for port 80.
- C. The access policy must allow traffic to the internal web server IP address.
- D. The NAT policy must be modified to translate the source IP address as well as destination IP address.
