Question 181: What is the function of policy-based IPsec VPN in FortiGate?
A) Define VPN based on traffic matching policies
B) Configure static routes only
C) Manage user accounts
D) Update firmware
Answer: A
Explanation:
Policy-based IPsec VPN defines VPN tunnels based on traffic matching specific policies, determining which traffic encrypts through VPN. This approach explicitly specifies interesting traffic. Organizations use policy-based VPN for straightforward site-to-site connections. With this type of VPN, administrators define policies specifying which traffic should be sent through the VPN tunnel. This typically includes source and destination addresses, ports, and protocols. The policies are evaluated on the traffic, and when a match is found, the traffic is encrypted and sent through the tunnel, while non-matching traffic follows the usual routing path.
VPN policies specify source and destination addresses, determining encrypted traffic. Traffic matching the specified policies enters VPN tunnels, while other traffic bypasses the tunnel and takes its regular route. This clear separation of traffic provides better control over what is encrypted, and what remains in the clear. The configuration process for setting up policy-based VPNs is relatively simple, which makes it an attractive choice for smaller-scale, simpler network environments. These types of VPNs are often used for single site-to-site connections or basic configurations where specific subnets need to be securely linked across different locations.
The straightforward nature of policy-based VPNs means that the network administrator can define the exact scope of traffic that needs to be encrypted. By only including certain source and destination addresses, the policy-based VPN ensures that sensitive data traffic is protected, while non-sensitive data follows the regular path. This level of control is essential for organizations that need to ensure that only certain types of traffic are subject to the overhead of encryption.
However, there are several limitations associated with policy-based VPNs. One of the major drawbacks is that they are not well suited for supporting dynamic routing protocols. Since policy-based VPNs do not create virtual interfaces for routing protocols, they lack the flexibility needed to handle dynamic changes in routing tables. This makes it difficult to integrate them into larger, more dynamic networks where routing paths frequently change or where new routes are added or removed on the fly. In such networks, the manual definition and modification of policies required to accommodate changes can be burdensome and error-prone.
Another challenge with policy-based VPNs is that they do not scale well with complex topologies. When an organization grows and its network becomes more intricate, the simple model of defining a policy for each connection may not be sufficient. For example, when trying to implement a hub-and-spoke model or a mesh topology with multiple sites, the number of policies that need to be configured and maintained can become overwhelming. The static nature of policy-based VPNs makes it difficult to quickly adapt to changing network architectures, which can result in slower response times to network reconfigurations or new security requirements.
Additionally, adding new subnets to a policy-based VPN often requires manually updating the existing policies. As networks evolve and expand, this means that administrators must keep track of changes and ensure that VPN policies are updated accordingly. This manual process can become cumbersome in larger, dynamic networks where subnets are frequently added, removed, or reconfigured. Without an automated way to adjust the policies in response to network changes, organizations may face gaps in security or misconfigurations that leave parts of the network unprotected.
In contrast, route-based VPNs provide greater flexibility and scalability for more complex network architectures. A route-based VPN allows for dynamic routing, which makes it easier to adapt to changes in the network. By using virtual interfaces, route-based VPNs support the use of routing protocols such as OSPF or BGP. This enables automated adjustments to routing tables, allowing the VPN to seamlessly accommodate network changes without the need for manual policy modifications. Route-based VPNs also allow for more sophisticated configurations, such as hub-and-spoke or fully meshed topologies, which would be difficult to manage using a policy-based approach.
Organizations often select between policy-based and route-based VPNs based on their specific needs. For simpler use cases, such as straightforward site-to-site connections between two or a few locations, a policy-based VPN is usually sufficient. It is easy to set up and manage, and it provides clear control over which traffic is encrypted. However, for larger, more dynamic networks with complex routing requirements or multiple sites, a route-based VPN offers more flexibility and scalability. This flexibility makes it the preferred choice for organizations with complex network infrastructures or those that require the ability to support dynamic routing protocols.
Question 182: Which command displays FortiGate hardware sensors?
A) show hardware sensors
B) execute sensor list
C) display sensors
D) get system status
Answer: B
Explanation:
The execute sensor list command displays FortiGate hardware sensors showing temperatures, voltages, and fan speeds. This command provides crucial information about the hardware health of the system. By monitoring these sensors, administrators can ensure that the device is operating within safe environmental conditions, helping to prevent hardware failures and maintaining the stability of the network infrastructure. This proactive monitoring can save organizations from costly repairs or downtime by identifying potential issues before they lead to system failure.
Temperature sensors are designed to monitor critical components, including the CPU, chipsets, and chassis. These sensors track the temperature of key hardware parts to ensure they stay within safe operating limits. If the temperature of any critical component exceeds safe thresholds, it could indicate a cooling problem, such as a malfunctioning fan or poor airflow in the device. Excessive heat can lead to thermal damage, shortening the lifespan of components and potentially causing system outages or permanent hardware failure. By continuously monitoring the temperature, administrators can identify overheating issues early and take corrective actions, such as adjusting fan speeds, improving cooling mechanisms, or replacing faulty components.
Voltage sensors play an essential role in ensuring that the power supply outputs remain within specifications. Power supplies are crucial for stable system operation, and any voltage fluctuations can signal potential problems. Voltage deviations from the expected range may indicate issues such as power supply failure, electrical instability, or problems with the power grid. These fluctuations can cause system crashes, corruption of data, or, in extreme cases, permanent damage to hardware components. Monitoring the voltage helps administrators detect any discrepancies and take corrective actions, such as replacing faulty power supplies or addressing electrical issues in the environment, to ensure the system continues to run reliably.
Fan speed sensors are another critical part of hardware monitoring. Cooling fans are responsible for maintaining an optimal temperature inside the device by dissipating heat generated by internal components. If a fan fails or its speed drops significantly, the internal temperature can rise quickly, leading to overheating and potential hardware damage. Monitoring fan speeds allows administrators to detect fan failures or performance degradation before they become serious issues. Proactive fan replacement or maintenance can prevent overheating, ensuring the longevity of hardware components and the overall stability of the device. If a sensor detects a drop in fan speed or a fan failure, it triggers an alert so that the problem can be addressed promptly.
Sensor readings outside of normal ranges trigger alerts, providing organizations with early warnings of potential hardware issues. These alerts are crucial for proactive system management, allowing administrators to respond to hardware health concerns before they escalate into full-blown failures. For instance, an alert for high temperatures may prompt a quick investigation to determine whether the cooling system is functioning properly, while a voltage fluctuation alert could prompt a check on the power supply or electrical infrastructure. Proactive response to these alerts helps prevent expensive hardware repairs, extended downtimes, or catastrophic hardware failures that could impact network performance and business operations.
Regular environmental monitoring should be a routine part of system maintenance for any organization. By establishing baselines for sensor readings, administrators can gain a clear understanding of what constitutes normal operation for the device. These baselines are typically based on the system’s historical data, which helps administrators detect deviations from the norm. For example, if the temperature or voltage readings are suddenly higher than usual, it may indicate that something has changed within the system or the environment, such as a malfunctioning component or a change in room temperature. In such cases, it is essential to investigate the issue further and take corrective actions to return the system to normal operating conditions.
When deviations from normal sensor readings are detected, it is essential to trigger an investigation to determine the root cause of the issue. Identifying the underlying problem is key to preventing recurrence and ensuring the continued reliability of the system. Corrective actions can range from simple fixes, such as replacing a faulty fan or cleaning dust buildup from cooling vents, to more complex solutions, like upgrading the power supply or reconfiguring the system’s airflow. Addressing these issues promptly not only ensures system stability but also extends the lifespan of the hardware, reducing the likelihood of unplanned downtimes and minimizing the need for expensive repairs or replacements.

Once authenticated, users can be placed into specific user groups, and network access can be granted or restricted based on these group memberships.
By using user-based policies, administrators can ensure that only authorized users have access to sensitive or restricted parts of the network. This also enhances security by limiting access based on roles or responsibilities.
Question 191: What is the purpose of the ‘HA (High Availability)’ feature in FortiGate devices?
A) To allow for redundancy and failover between multiple FortiGate units in a cluster
B) To increase the throughput of a single FortiGate device
C) To configure multiple VPNs between FortiGate devices
D) To isolate different network segments for security purposes
Answer: A
High Availability (HA) in FortiGate is a feature designed to ensure continuous network service by allowing multiple FortiGate devices to work together in a cluster. This is particularly useful in environments where network uptime is critical, as it provides redundancy in case one of the devices in the cluster fails. The HA feature helps to reduce the risk of network outages and provides an automatic failover mechanism that ensures traffic continues to flow uninterrupted.
When two or more FortiGate units are configured in HA mode, one unit typically acts as the active unit, processing all traffic, while the other unit(s) remain in standby mode, ready to take over if the active unit experiences a failure. FortiGate supports different HA modes, such as Active-Passive and Active-Active. In Active-Passive mode, only one unit processes traffic at a time, and the other unit(s) are kept as a backup. In Active-Active mode, multiple units share the processing of traffic, which can help balance the load between them.
This configuration ensures that if the primary FortiGate unit fails, the backup unit takes over seamlessly without disrupting network services. Additionally, synchronization of configuration and session information between the units allows for smooth failover, making the backup unit fully capable of continuing the service without manual intervention. High Availability enhances the reliability and resilience of a network infrastructure by minimizing downtime and ensuring that business operations are not affected by a single point of failure.

By integrating FortiGate with FortiAnalyzer, administrators can monitor and analyze logs from all devices within the security fabric, gaining a comprehensive view of security events, incidents, and overall network health.
The integration with FortiAnalyzer helps provide better visibility and situational awareness of the network’s security status. Security administrators can use FortiAnalyzer to collect detailed logs from FortiGate devices, generate reports, and analyze the data for security threats, policy violations, and performance issues. This centralized log collection is critical for proactive network management and incident response, as it allows security teams to detect and respond to threats in a timely manner.
FortiAnalyzer also facilitates event correlation, which is particularly useful for identifying complex security incidents that might span multiple devices. For example, if a potential threat is detected on one FortiGate unit, the event can be correlated with data from other devices in the network, such as intrusion prevention systems or email security gateways, to form a more complete picture of the threat landscape. This correlation improves the ability to detect, investigate, and mitigate advanced attacks that may otherwise go unnoticed.
Question 193: When configuring a FortiGate device for SSL VPN, which of the following is required for remote users to access internal resources securely?
A) An SSL certificate for encrypting the connection
B) A dedicated VPN appliance for traffic encryption
C) A remote access policy defined for all users
D) A FortiGate configuration with IPSec tunnels
Answer: A
Explanation:
For remote users to securely access internal resources over the internet, an SSL VPN must be configured on the FortiGate device. The SSL VPN relies on SSL or TLS (Transport Layer Security) to encrypt the communication between the remote user and the FortiGate appliance, ensuring the confidentiality and integrity of the data in transit. To establish this secure connection, an SSL certificate is required.
The SSL certificate is used to authenticate the FortiGate device to the remote users and to establish an encrypted connection between the client (remote user) and the FortiGate device. Typically, this SSL certificate is issued by a trusted Certificate Authority (CA). The certificate ensures that users can verify the identity of the FortiGate device they are connecting to, preventing man-in-the-middle attacks.
In an SSL VPN configuration, users connect to a secure web portal hosted by the FortiGate device, where they authenticate using their credentials. Once authenticated, they can access internal resources like web applications, file shares, or email servers as if they were on the local network. SSL VPN is particularly useful because it works over standard web browsers, eliminating the need for special client software, making it easier for users to access the network securely from various devices, including laptops, smartphones, and tablets.

B) Enable SSL VPN between two branch offices for backup traffic
C) Use a dedicated load balancer to distribute Internet traffic across links
D) Configure a secondary WAN interface to handle failover in case of primary WAN link failure
Answer: A
Explanation:
A valid method for creating a redundant Internet connection for a branch office is to configure multiple IPSec VPN tunnels between two FortiGate devices and enable SD-WAN (Software-Defined Wide Area Network). SD-WAN provides an intelligent way to manage multiple WAN links, optimizing traffic flow based on factors such as performance, cost, and link availability. This setup ensures that the branch office has a reliable Internet connection with automatic failover and load balancing capabilities.
In this configuration, two IPSec VPN tunnels are created between the FortiGate devices in the branch office and the data center or headquarters. One tunnel serves as the primary link for traffic, while the other acts as a backup. By enabling SD-WAN, the FortiGate device can monitor the health and performance of both links. If one of the links experiences issues, SD-WAN can automatically reroute traffic through the secondary VPN tunnel without interrupting the service.
SD-WAN also helps improve network performance by dynamically selecting the best path for each type of traffic based on real-time conditions, such as latency, jitter, and packet loss. This ensures that critical applications and services always have the best possible connection, even if one of the WAN links goes down. Additionally, SD-WAN supports the use of various types of WAN connections, including broadband, MPLS, LTE, and others, providing flexibility in choosing the most cost-effective and reliable links for the branch office.
Question 196: What is the purpose of using the ‘FortiGate Virtual Domains (VDOMs)’ feature?
A) To segment the network into multiple isolated virtual firewalls

Explanation:
FortiGate Virtual Domains (VDOMs) allow administrators to segment the network into multiple isolated virtual firewalls within a single FortiGate unit. Each VDOM functions as an independent firewall with its own policies, interfaces, routing tables, and configurations, providing the ability to manage different security zones or customer networks separately.
The main purpose of using VDOMs is to simplify network segmentation and provide a flexible way to manage multiple environments or security domains with a single FortiGate device. VDOMs are typically used in multi-tenant environments, where different groups or customers require independent security policies but can share the same physical hardware. This is also beneficial in large organizations that need to separate departments or regions for administrative purposes.
Each VDOM can be configured independently, which allows administrators to apply specific security measures, routing, and network address translations (NAT) for different segments of the network. Additionally, FortiGate supports features like firewall policies, VPN tunnels, and intrusion prevention systems (IPS) for each VDOM. This makes VDOMs a powerful tool for ensuring the isolation and security of different parts of the network.
While VDOMs provide flexibility, managing a large number of VDOMs can become complex, particularly as each VDOM requires its own configuration and maintenance. VDOMs are a great solution for environments where strict isolation of network traffic is needed, but organizations should consider the complexity involved in large-scale VDOM management.
Question 197: What is the role of the FortiGate ‘Antivirus’ feature in the context of network security?
A) To scan incoming and outgoing emails for spam and phishing attempts
B) To detect and block malware and other malicious software in network traffic

This feature is especially useful for organizations that want to control employees’ or users’ access to certain types of websites, ensuring that only authorized and safe sites are accessible.
By implementing Web Filtering, administrators can block or restrict access to websites based on predefined categories, such as social media, adult content, gambling sites, or gaming. This provides a way to enforce acceptable use policies and ensure that employees or users are not accessing inappropriate or non-work-related content, which could lead to security risks, decreased productivity, or legal issues.
The Web Filtering feature can also help mitigate the risk of users visiting sites that could potentially introduce malware, phishing attacks, or other types of malicious content. For example, an organization might block access to websites known for hosting malicious software or phishing sites that could compromise network security.
Administrators can configure FortiGate to block websites in real-time based on categories or even apply custom policies to create more granular controls. This level of filtering can be customized to suit specific needs, such as blocking access to certain sites for specific user groups or departments.
Question 199: What is the function of the ‘FortiGate Application Control’ feature?
A) To filter specific applications and protocols based on their behavior
B) To control access to websites based on DNS requests
C) To scan email traffic for phishing and spam
D) To inspect traffic for viruses and malware in real-time
Answer: A
Explanation:
FortiGate Application Control is a feature that allows administrators to identify and control the use of specific applications on the network, regardless of the port or protocol used. This feature uses deep packet inspection (DPI) to analyze the payload of network traffic and determine the type of application generating that traffic.
Application Control works by maintaining a database of known applications, which includes both legitimate applications and potentially risky or unwanted applications. For example, it can detect and block peer-to-peer file-sharing applications, video streaming services, or cloud storage apps that may consume excessive bandwidth or present a security risk. By controlling the use of these applications, organizations can prevent their employees from engaging in non-business-related activities or from inadvertently exposing the network to security risks.
Additionally, Application Control is particularly useful for preventing the use of unauthorized or unapproved applications that could bypass traditional firewall rules. For instance, it can detect applications that hide behind common ports or protocols, such as HTTP or HTTPS, and block them even if they are not using the standard ports typically associated with their traffic.
This feature provides administrators with granular control over application usage and helps ensure that only authorized applications are running on the network. It also improves bandwidth management by blocking or limiting non-essential applications that could consume valuable network resources.
Question 200: How does FortiGate’s ‘SD-WAN’ feature enhance WAN performance and reliability?
A) By using traditional MPLS circuits to increase connection speed and reliability
B) By automatically switching to secondary internet connections in case of link failure
C) By encrypting traffic between remote sites to ensure secure communication
D) By managing traffic based on DNS requests and providing high-level security filtering
Answer: B
Explanation:
SD-WAN (Software-Defined Wide Area Network) is a feature provided by FortiGate that optimizes and enhances the performance and reliability of WAN connections. Traditionally, WAN links like MPLS or leased lines were static, meaning that if one link failed, the entire network might experience downtime or significant degradation in performance. FortiGate’s SD-WAN solves this problem by enabling automatic path selection and failover, improving the overall reliability of the network.
The SD-WAN feature allows multiple WAN links, such as broadband, MPLS, or LTE, to be used simultaneously. FortiGate continuously monitors the performance of these links based on metrics like latency, jitter, packet loss, and bandwidth usage. If the primary link experiences issues, SD-WAN automatically reroutes traffic through the secondary link, ensuring that business operations continue without interruption. This failover process is seamless, and users typically don’t notice any disruption in service.
Moreover, SD-WAN also enables load balancing, which allows traffic to be distributed across multiple links according to their capacity and performance. This is especially useful in environments where high availability and low latency are critical, such as VoIP or video conferencing applications. By dynamically selecting the best path for each type of traffic, SD-WAN helps ensure that network resources are used optimally and that users experience consistent performance.
In addition to improving performance and reliability, SD-WAN can also help reduce WAN costs. Organizations can use cheaper broadband connections alongside more expensive MPLS links, and SD-WAN will automatically route traffic based on performance rather than just a fixed path. This flexibility enables businesses to optimize their WAN infrastructure while maintaining high levels of reliability and performance.
