NEW QUESTION # 29
When Mobile VPN is enabled, remote users receive the domain name and DNS servers from the Firebox Network Configuration by default.
- A. False
- B. True
Answer: B
Explanation:
WhenMobile VPNis enabled on a Firebox, remote users receive network configuration settings, including domain nameandDNS server informationfrom the Firebox by default. This setupensures that remote users can resolve internal domain names and access network resources as though they were connected directly to the internal network. This functionality is essential for maintaining consistent user experience and connectivity while working remotely.
NEW QUESTION # 30
If policies are automatically ordered, which of these policies has the highest precedence? (Select one.)
- A. HTTPS policy - From: Trusted To: Any-External
- B. HTTPS policy - From: User1@Firebox-DB To: Any-External
- C. Outgoing policy - From: Any-Trusted, Any-Optional To: Any-External
- D. HTTPS policy - From: Any-Trusted, Any-Optional To: Any-External
Answer: B
Explanation:
When policies are automatically ordered, policies with more specific user-based criteria have higher precedence over general policies. In this scenario, an HTTPS policy for a specific user (e.g.,User1@Firebox- DB) would take precedence over policies that apply to broader groups or networks, such asAny-Trustedor Any-Optional. This ordering ensures that individual user rules are evaluated first before generic policies, providing finer access control.
NEW QUESTION # 31
In a Mobile VPN configuration, why would you choose default-route (full tunnel) VPN instead of split tunnel VPN? (Select one.)
- A. Default-route VPN is the only option you can use to apply security services to connections routed to your internal servers.
- B. Default-route VPN uses less processing power.
- C. Default-route VPN uses less bandwidth.
- D. Default-route VPN automatically allows dynamic NAT.
- E. Default-route VPN enables your Firebox to examine all remote user traffic.
Answer: E
Explanation:
In a Mobile VPN setup, adefault-route (full tunnel)VPN routes all of a remote user's internet traffic through the VPN tunnel to the Firebox. This configuration allows the Firebox to inspect and apply security policies to all traffic, including traffic that is not destined for internal network resources. In contrast, asplit tunnel VPN would route only traffic meant for the internal network through the VPN, while internet-bound traffic would bypass the Firebox, potentially exposing it to threats and limiting the Firebox's ability to inspect all traffic.
NEW QUESTION # 32

NEW QUESTION # 33
If a Firebox has two trusted interfaces enabled, the default policies allow HTTPS connections between computers on different trusted networks.
- A. False
- B. True
Answer: A
Explanation:
By default, Firebox policies do not allow HTTPS connections between devices on separate trusted networks without specific policy configuration. Firebox's default security posture is to restrict inter-network traffic unless explicitly permitted, enhancing network segmentation and security within trusted zones.
NEW QUESTION # 34
Match each type of NAT with the correct descriptor
Answer:
Explanation:
Explanation:
Here are the correct answers for matching each NAT type with its descriptor:
* Changes incoming packets sent to a public IP address to different internal IP addresses based on the destination portanswer:Static NAT Explanation: Static NAT maps a public IP address to multiple internal IP addresses based on the port, allowing specific services or applications to be routed to various internal destinations.
* Allows a user on the trusted or optional network to connect to a public server that is on the same physical Firebox interface by its public IP address or domain nameanswer:NAT loopback Explanation: NAT loopback (or NAT reflection) allows internal users to access a public IP address or domain name that resolves to the same local network, making it appear as if they are connecting from outside the network.
* Conserves IP addresses and hides the internal topology of your networkanswer:Dynamic NAT Explanation: Dynamic NAT (or PAT - Port Address Translation) conserves public IP addresses by allowing multiple internal devices to share a single public IP address. This setup is commonly used for outbound internet connections from a private network.
* Changes all incoming and outgoing packets sent from one range of addresses to a different range of addressesanswer:1-to-1 NAT Explanation: 1-to-1 NAT maps each internal IP address to a unique public IP address, providing a one-to-one relationship. This type of NAT is often used for networks that require external access to specific internal resources.
NEW QUESTION # 35
You recently installed network monitoring software on your server and then performed a port scan for each IP address in the network. When the scan finishes, you notice that the server lost access to the Internet. What is the most likely cause of this issue? (Select one.)
- A. The server IP address was added to the Blocked Sites list because an IPS signature was matchedduring the port scan
- B. The port scan traffic matched a default HTTP proxy content type rule configured with a Block action
- C. The server IP address was added to the Blocked Sites list because of the default packet handling port scan rule
- D. The server IP address was added to the Blocked Sites list because the network was flooded with ESP traffic during the port scan
- E. The policy that handles outbound traffic was automatically disabled because the Firebox was port scanned
Answer: C
Explanation:
When a port scan is detected, Firebox devices with default settings often include a rule to add the source IP address of the scan to the Blocked Sites list to prevent potential threats. This is a standard security measure in Firebox configurations, aimed at mitigating the risk of network scanning attempts. Consequently, if the server you used to perform the port scan was added to the Blocked Sites list, it would lose Internet access as the device blocks any outgoing connections from that IP. This behavior aligns with Firebox's handling of port scan detection through default security rules.
NEW QUESTION # 36
You want to create a branch office VPN virtual interface between a remote Firebox and your headquarters Firebox so the remote Firebox can send log data to a server at headquarters. For the log data to be sent from the remote Firebox over the VPN successfully, what BOVPN virtual interface setting must you configure?
(Select one.)
- A. Dead Peer Detection (DPD)
- B. Virtual IP addresses
- C. An IPSec certificate, instead of a Pre-shared key
- D. Perfect Forward Secrecy (PFS)
- E. IKEv2 in the Phase 1 settings
Answer: B
Explanation:
To enable the remote Firebox to send log data to a server at headquarters through a Branch Office VPN (BOVPN) virtual interface, you must configureVirtual IP addresses. Virtual IPs enable devices on either end of the VPN tunnel to communicate as if they are on the same network, facilitating routing of log data from the remote Firebox to the log server located at headquarters.
Other options likeIPSec certificatesandIKEv2are not specifically required for this configuration, though they can enhance security.Dead Peer Detection (DPD)andPerfect Forward Secrecy (PFS)are useful for maintaining VPN stability and security but are not directly necessary for enabling log transmission.
NEW QUESTION # 37
There is an Internet outage at your primary ISP, but the Internet connection from the Firebox has not failed over to your backup ISP. Both ISP connectors are correctly cabled and have active physical links. What could cause this problem? (Select two.)
- A. In the Multi-WAN settings, the Immediate Fallback option is enabled
- B. The secondary IP addresses are not defined for the backup ISP interface
- C. In the Multi-WAN settings, the Gradual Fallback option is enabled
- D. The Link Monitor target for the primary ISP interface is set to ping the default gateway, but the outage is further upstream
- E. Link Monitor target for the backup ISP interface is not responding
Answer: D,E
Explanation:
* Link Monitor Target for Backup ISP: If the backup ISP's Link Monitor target is not responsive, the Firebox will not initiate a failover, as it interprets the backup connection as inactive or faulty.
* Primary ISP Link Monitor Configuration: When the Link Monitor for the primary ISP only checks the default gateway, it may not detect issues occurring further upstream. If the outage is beyond the gateway, failover will not activate because the monitor assumes the link is still valid.
These settings are critical to ensuring proper Multi-WAN failover behavior in case of ISP issues.
NEW QUESTION # 38
A Firebox has an external IP address of 203.0.113.100. A public web server with the IP address 10.0.1.80 is connected to a Firebox internal network. What is the effect of the policy shown in this image? (Select one.)
- A. Allows users on the Internet and the 10.0.1.0/24 network to use the internal IP address of the Firebox to connect to the web server
- B. Allows users on the Internet and the 10.0.1.0/24 network to use the external IP address of the Firebox to connect to the web server
- C. Allows users on the Internet to connect to the 10.0.1.80 IP address of the web server
- D. Applies dynamic NAT to the 10.0.1.80 IP address of the web server to allow inbound connections
Answer: B
Explanation:
In the policy configuration shown in the image:
* From Section: It specifies "Any-External" and 10.0.1.0/24, indicating that this policy applies to traffic from any external source (Internet users) as well as from devices on the internal network 10.0.1.0/24.
* To Section: The destination specifies a public-facing IP address (203.0.113.100) that is statically NAT'd to the internal IP address of the web server (10.0.1.80). This means external users and internal users can access the web server using the Firebox's external IP.
* Effect of Static NAT: The policy uses Static NAT to map the Firebox's external IP address to the web server's internal IP address, allowing inbound connections to reach the server. This setup provides consistent access for both external and internal users via the same public IP address.
This configuration effectively enables both Internet users and users within the specified internal network (10.0.1.0/24) to connect to the web server using the Firebox's external IP, makingOption Dthe correct answer.

NEW QUESTION # 41
Which of these statements are true for this log message? (Select three.)
- A. The URL path matched the proxy content type restrictions
- B. Application Control detected the application as a virus
- C. Gateway AntiVirus detected a virus
- D. The connection used an HTTP Packet Filter
- E. The connection was denied
- F. The connection used an HTTP Proxy
Answer: C,E,F
Explanation:
Analyzing a typical Firebox log message for a denied connection with an associated virus detection involves recognizing multiple elements:
* HTTP Proxy Detection (C): If the connection utilized an HTTP proxy, this is typically noted in the log. Firebox's HTTP proxy is often used to inspect and manage web traffic, including scanning for malicious content.
* Gateway AntiVirus Detection (D): This service scans HTTP traffic for malware and will generate log messages if it identifies a virus. When a virus is detected, the action taken is generally to block the connection.
* Connection Denial (E): When a threat is detected (e.g., a virus via Gateway AntiVirus), Firebox policies are configured to deny the connection to prevent potential infection or data breaches. This is logged as a denied connection.
Other options, such as Application Control detecting a virus or the use of an HTTP Packet Filter, are not relevant in this context based on the function of HTTP proxies and Gateway AntiVirus in Firebox logs.
NEW QUESTION # 42
You can run TCP Dump directly from the Firebox.
- A. False
- B. True
Answer: A
Explanation:
You cannot runTCP Dumpdirectly from a Firebox device. While Firebox has various monitoring tools such as Traffic Monitor and Firebox System Manager, it does not natively support TCP Dump, which is a command-line tool primarily available on Linux-based systems. Instead, packet captures and traffic monitoring need to be handled through Firebox-specific tools or by exporting logs to external devices for further analysis.
NEW QUESTION # 43
Which of these is a network IP address? (Select one.)
- A. 10 0.1 255 8
- B. 172 16 100 1/12
- C. 10 10 10 255/24
- D. 1Q2 158.10 0-24
- E. 1G2 153 10 O 1
Answer: C
Explanation:
In this question, we need to identify the correctly formatted network IP address. IPv4 addresses are represented in a dotted decimal format, typically in the form of x.x.x.x/n, where x represents decimal values from 0 to 255, and /n is the CIDR notation indicating the subnet mask. Among the options:
* Option E (10 10 10 255/24)fits the IPv4 standard and CIDR notation.
* The other options contain invalid characters or formats (letters like "G" or "Q" or unusual symbols like
"O" or "-") and do not conform to IP addressing standards.
NEW QUESTION # 44
What is true about this log message? (Select three.)
- A. The Gateway AntiVirus service denied the email traffic because it matches the 18.254 virus signature
- B. The HTTPS proxy identified a TLS v1.3 connection to the inbox.google.com SNI domain
- C. The traffic is allowed inbound through the Firebox
- D. The Application Control service has identified the traffic as Gmail
- E. The traffic is allowed outbound through the Firebox
Answer: B,D,E
Explanation:
Application Control Identifying Gmail Traffic: Application Control is capable of identifying and categorizing applications based on traffic patterns and signatures. In this case, it recognizes Gmail traffic, which is a typical function of Application Control for managing and monitoring web applications. This functionality allows administrators to monitor and control access to applications based on organizational policies.
HTTPS Proxy Identifies TLS v1.3 Connection: The HTTPS proxy in Firebox can inspect and manage encrypted traffic by recognizing details such as the Server Name Indication (SNI) field in TLS connections.
By identifying a TLS v1.3 connection to the inbox.google.com domain, the HTTPS proxy provides additional monitoring and control capabilities over encrypted connections.
Traffic Allowed Outbound Through the Firebox: Given that the log indicates outbound traffic, this confirms that the connection is permitted by the Firebox's policies for outbound traffic. Outbound traffic control is crucial for managing access to external resources and ensuring that only authorized traffic exits the network.
NEW QUESTION # 45
You configured a Firebox for a school environment. Students must have more restricted access than teachers, and unauthenticated users cannot have any Internet access. You added Student and Teacher groups to your proxy policies that handle web traffic. Based on the image below, this configuration can accomplish your goals.
- A. False
- B. True
Answer: B
Explanation:
The image shows a configuration for a school environment with separateHTTPandHTTPS proxy policiesfor StudentsandTeachers. This separation allows for different levels of access control based on group membership, providing more restrictive access for students compared to teachers.
* Studentsare restricted by specific HTTP and HTTPS proxy policies, limiting their access to designated content and sites.
* Teachershave their own policies, which can be configured with more permissive rules.
* Unauthenticated users are not included in any policy, effectively blocking their internet access, as the firewall denies traffic not explicitly allowed by a policy.
This configuration meets the requirements by:
* Allowing teachers and students access as per their respective policies.
* Blocking unauthenticated users from internet access entirely.
