Question 41: What is the function of conserve mode in FortiGate?
A) Power saving
B) Protect system when resources are low
C) Increase speed
D) Backup configuration
Answer: B
Explanation:
Conserve mode protects FortiGate systems when resources approach critical levels, preventing complete system failure due to resource exhaustion. This protective mechanism activates when memory utilization exceeds defined thresholds. FortiGate restricts certain operations to preserve resources for critical functions.
When conserve mode activates, FortiGate prioritizes essential functions like forwarding traffic and maintaining existing connections. Administrative functions may be limited to prevent further resource consumption. This prioritization ensures the firewall continues protecting the network despite resource pressure.
Memory conservation triggers occur at different severity levels. Initial warnings appear when memory usage reaches moderate levels. Red conserve mode activates at critical thresholds, implementing aggressive resource preservation. Administrators receive notifications enabling proactive response.
Common causes of conserve mode include excessive session counts, logging configurations, or memory leaks. Administrators should investigate underlying causes rather than simply increasing memory. Proper sizing and configuration prevent conserve mode activation.
During conserve mode, certain features may be disabled including new administrative connections, detailed logging, or resource-intensive inspection. Existing sessions continue functioning normally. The firewall automatically exits conserve mode when resource utilization decreases.
Organizations should monitor resource utilization trends to identify increasing memory consumption. Proactive capacity management prevents conserve mode activation. Regular firmware updates address known memory leaks.

Question 43: What is the purpose of session helpers in FortiGate?
A) User management
B) Handle complex protocols requiring multiple connections
C) Firmware updates
D) Power configuration
Answer: B
Explanation:
Session helpers in FortiGate handle complex protocols requiring multiple connections or dynamic port usage. These protocols include FTP, H.323, SIP, and others that negotiate secondary channels during sessions. Session helpers inspect protocol communications and dynamically open necessary firewall pinholes.
Without session helpers, protocols like FTP fail through stateful firewalls. FTP control channel negotiates data channel port numbers dynamically. Session helpers monitor FTP control traffic and automatically allow corresponding data connections. This automation eliminates manual policy creation for dynamic ports.
Session helpers understand application-layer protocols, extracting relevant information from packet payloads. For SIP protocol, helpers extract IP addresses and port numbers from SIP messages. The firewall then permits RTP media streams between negotiated endpoints.
Organizations can enable or disable specific session helpers based on security policies. Some helpers may represent security risks if not carefully managed. Disabling unused helpers reduces attack surface.
Session helper configuration occurs in system settings, specifying which protocols receive assistance. Some helpers include tunable parameters adjusting behavior. Default settings work for most environments without modification.
ALG is another term for session helpers, referring to Application Layer Gateways. These components bridge application-layer protocols with network security. Proper helper configuration ensures application functionality while maintaining security.
Question 44: Which command saves configuration changes in FortiGate CLI?
A) save config
B) end
C) write config
D) commit
Answer: B
Explanation:
In FortiGate CLI, the end command is crucial for saving configuration changes, exiting configuration mode, and committing any modifications made during a session. It’s a necessary step after making changes in the CLI, as it ensures that the adjustments are not only saved but also applied. Without using end, the changes will remain uncommitted, and any session closure or accidental command might result in the loss of those changes.
FortiGate CLI operates in a hierarchical configuration structure, meaning that configurations are organized into different levels. Administrators navigate through these levels using config commands, moving from general settings down to more specific options. Once you have finished making the desired changes at a particular configuration level, the end command brings you back to the root level of the configuration hierarchy while simultaneously saving and applying all changes made in that session.
When the end command is executed, FortiGate performs a configuration validation process. This ensures that the syntax of the configuration is correct before any changes are applied. If any part of the configuration contains errors or invalid settings, FortiGate will generate an error message and will not apply the invalid changes. This built-in validation helps prevent misconfigurations that could potentially disrupt network operations or cause service outages.
Once the end command has been executed, administrators can verify that their changes were successfully applied by using commands such as show. The show command allows you to display the current configuration, confirming that the intended modifications are reflected in the system. This verification step is an essential practice in network administration, ensuring that changes were applied as intended and reducing the likelihood of mistakes going unnoticed.
On the other hand, the exit command is similar to end but has a distinct purpose. While exit moves you up one level in the configuration hierarchy without saving any changes, it does not commit or apply any modifications. This means you can use exit to navigate through configuration levels, but to save and apply changes, you must ultimately use the end command. Multiple exit commands may be required to reach the root configuration level, depending on the depth of your navigation within the CLI hierarchy.
A best practice when working in FortiGate’s CLI is to make related configuration changes together before executing the end command. This approach ensures that all changes are made in a cohesive manner, reducing the risk of incomplete configurations or inconsistencies. By grouping related changes and committing them in a single step, administrators can maintain a more organized and systematic approach to configuration management. This strategy also simplifies troubleshooting, as it helps you isolate changes to specific areas of the configuration, making it easier to identify the source of any issues.
Additionally, it is often recommended to make incremental changes followed by verification. This practice involves applying smaller, manageable changes and confirming each step works as intended before proceeding further. This safer approach ensures that potential errors can be caught early in the process and that changes are more predictable and easier to roll back if necessary.
In summary, the end command in FortiGate CLI is essential for saving and applying configuration changes, exiting configuration mode, and validating the syntax of those changes. It ensures that modifications are committed and are reflected in the device’s configuration, helping prevent mistakes that could affect network stability. Using exit in contrast only moves you up one configuration level without saving any changes. Best practices encourage making related changes together before executing end and performing incremental changes with verification to ensure smoother and safer configuration management.
Question 45: What is the function of explicit proxy in FortiGate?
A) Transparent traffic interception
B) Require client proxy configuration
C) Automatic DNS resolution
D) DHCP service
Answer: B
Explanation:
Explicit proxy in FortiGate requires client applications to be manually configured with proxy settings, directing all web traffic through the FortiGate device. This mode is different from transparent proxy, where traffic is intercepted and redirected without any client-side configuration. The explicit proxy mode provides several advantages, including better control over application traffic and enhanced security features like user authentication.
In explicit proxy mode, clients must configure their applications with the proxy server’s address and port number, or set the proxy system-wide. Once configured, all web traffic from the client will be routed through the FortiGate proxy. The explicit nature of this setup allows FortiGate to recognize the original client’s IP address and, if configured, the associated user credentials. This enables more detailed monitoring, logging, and policy enforcement based on the identity and activity of the user or client.
One of the significant benefits of the explicit proxy mode is its ability to support user authentication directly through the proxy. When a user accesses the proxy, they are prompted to provide their credentials, which allows FortiGate to apply identity-based security policies. This authentication is done at the application level, meaning it doesn’t require network-level authentication or integration with technologies like FortiGate Single Sign-On (FSSO). This can simplify deployment and provide more flexibility for organizations that don’t want to rely on network-level authentication methods.
Explicit proxy also handles HTTPS traffic more effectively compared to transparent proxy. In transparent proxy mode, SSL interception and certificate trust can be complex and may result in security warnings or errors on the client side. Explicit proxy avoids these complications, as the browser establishes the SSL/TLS connection directly with the proxy server. During this process, users may be prompted to accept a certificate, but once accepted, the connection is trusted, and HTTPS traffic is handled more seamlessly.
FortiGate’s explicit proxy also supports a variety of authentication methods, including basic authentication, NTLM (NT LAN Manager), and SAML (Security Assertion Markup Language). These authentication methods allow organizations to choose the one that best fits their existing identity management infrastructure. For example, basic authentication might be suitable for smaller setups, while larger organizations that use Microsoft Active Directory might prefer NTLM or SAML for single sign-on capabilities. These integrated authentication methods ensure a smooth user experience, as they allow users to authenticate once and gain access to resources without needing to re-enter credentials repeatedly.
The configuration of explicit proxy in FortiGate involves defining several key parameters. Administrators need to specify the listening ports that the proxy will use, set authentication parameters, and define proxy policy rules. These rules govern how traffic is handled by the proxy, including which types of traffic are allowed or denied, and how different users or groups are treated. This configuration is separate from the traditional firewall policies, allowing for more granular control over proxy operations. By separating proxy-related policies from general firewall rules, organizations can fine-tune their security posture to meet specific needs, such as restricting access to certain websites for certain users or enabling content filtering for specific applications.
In summary, the explicit proxy mode in FortiGate offers enhanced control over network traffic, user authentication, and application-level filtering. By requiring client applications to be configured with proxy settings, FortiGate can identify users, enforce identity-based policies, and handle HTTPS traffic more effectively than in transparent proxy mode. With support for a variety of authentication methods, explicit proxy provides flexibility and seamless integration with existing identity management systems. The configuration options, such as defining listening ports, authentication parameters, and policy rules, allow administrators to tailor the proxy to the organization’s specific needs, offering a secure and efficient way to manage web traffic.
Question 46: Which protocol does FortiGate use for SSL VPN?
A) IPsec only
B) SSL/TLS
C) PPTP
D) L2TP
Answer: B
Explanation:
FortiGate utilizes SSL/TLS protocols for its SSL VPN, providing a secure method for remote access through standard HTTPS connections. This technology is designed to enable users to securely connect to a network from almost any location, particularly when they are on untrusted networks where traditional IPsec VPN connections might be blocked. SSL VPN works through web browsers or dedicated client applications, making it a versatile and convenient solution for remote work and access.
The core of SSL VPN is the use of SSL/TLS encryption, which is the same protocol that secures web traffic for HTTPS connections. This encryption creates a secure tunnel between the client and the FortiGate device, ensuring that all data transmitted over the connection is protected. The advantage of using SSL/TLS for VPN connections is that HTTPS traffic is rarely blocked by firewalls, which allows users to bypass many restrictions they might face on public or untrusted networks. As a result, users can securely connect to their organization’s network from a wide range of locations without requiring complex firewall rule changes.
FortiGate SSL VPN supports multiple access modes to meet different needs. Web mode provides clientless access, allowing users to connect to specific web applications hosted on the network without the need for a VPN client. This is ideal for users who only need access to a few web-based resources. Tunnel mode, on the other hand, creates a full network-layer VPN connection, giving users access to all the resources on the corporate network, much like they would have if they were physically present in the office. Additionally, FortiGate offers FortiClient integration, which provides a dedicated VPN client for users who need a more robust and feature-rich connection.
Authentication for SSL VPN is flexible and supports various methods, including username/password, certificates, and two-factor authentication (2FA). This flexibility allows organizations to choose the authentication mechanism that best fits their security requirements. FortiGate can integrate with external authentication servers, such as LDAP or RADIUS, for centralized credential management, making it easier to manage user access. Certificate-based authentication, which eliminates the need for passwords, offers a higher level of security because it is less vulnerable to common attack methods, such as phishing or brute-force password attacks.
SSL VPN policies in FortiGate allow administrators to define granular access controls. These policies specify which users or user groups are allowed to access particular resources, providing a high level of flexibility. For example, some users may be restricted to accessing specific applications, while others may have broader access to the network. Administrators can also configure custom portals that define the user experience and the resources available to them. These portals can be tailored to present users with a list of applications, tools, or network resources that are relevant to their role or needs, enhancing both usability and security.
One important consideration when implementing SSL VPN is performance. SSL/TLS encryption operations are processor-intensive, which can impact the capacity of the FortiGate device, particularly when handling many concurrent users. To address this, higher-end FortiGate models include SSL acceleration hardware, which offloads the encryption workload from the main processor, improving performance and supporting a larger number of simultaneous SSL VPN connections. Organizations should carefully size their FortiGate device based on the expected number of remote users and the level of encryption required. For example, if an organization expects a high volume of remote users, investing in a model with dedicated SSL acceleration hardware is advisable to ensure a smooth experience for all users.
Question 47: What is the purpose of port forwarding in FortiGate?
A) Increase interface count
B) Direct external traffic to internal servers
C) Reduce power consumption
D) Update firmware
Answer: B
Explanation:
Port forwarding in FortiGate is a technique used to direct external traffic arriving at specific ports to internal servers, allowing external users to access services hosted within the internal network. This is typically used to expose services such as web servers, email servers, or custom applications to the internet. By configuring port forwarding, organizations can map external IP addresses and ports to different internal addresses and ports, ensuring that services are available externally without exposing internal infrastructure directly.
The configuration of port forwarding in FortiGate involves the creation of virtual IPs (VIPs), which define the external IP addresses and the corresponding port mappings to internal destinations. For example, a virtual IP might map an external IP address on port 8080 to an internal web server’s port 80. Once these mappings are set up, firewall policies are then used to specify which types of traffic can reach the internal services. These policies reference the virtual IPs, controlling access to the mapped ports based on source addresses, protocols, or other criteria.
A key advantage of port forwarding is the ability to use non-standard external ports while internal services continue to listen on standard ports. For example, external users can access an internal web server by connecting to port 8080 on the FortiGate device, which is then forwarded to port 80 on the internal web server. This method, known as “port obfuscation,” helps obscure the actual internal ports and can enhance security by making it less obvious which services are running internally.
Another benefit of port forwarding is the ability to use a single external IP address to provide access to multiple internal services. For instance, an organization can configure the FortiGate device to forward external traffic on port 80 to an internal web server, while traffic on port 25 is forwarded to an internal email server. This way, multiple services can be hosted behind a single public IP address, maximizing the utilization of limited public IP resources.
However, security considerations must be taken into account when setting up port forwarding. One of the most important measures is restricting which external sources are allowed to access forwarded services. This can be done by setting up firewall policies that limit access based on source addresses, ensuring that only trusted users or systems can reach the internal servers. For example, an email server may only need to be accessed by users from specific IP ranges, so a firewall policy can restrict access to those IPs while blocking all others.
In addition to basic firewall policies, FortiGate offers the ability to apply security profiles to further protect the forwarded services. For example, administrators can enable features like web filtering, intrusion prevention, and antivirus scanning to mitigate the risk of attacks that target publicly available services. These security profiles help defend against common vulnerabilities and exploits, such as SQL injection, cross-site scripting, and brute-force login attempts, which are often targeted at services exposed through port forwarding.
In summary, port forwarding in FortiGate allows organizations to securely expose internal services to the internet by mapping external ports to internal destinations. It enables flexibility in managing service access, such as using non-standard external ports for standard internal services and optimizing the use of public IP addresses. While configuring port forwarding, organizations should consider security best practices, including restricting access by source address and applying additional security profiles to protect the exposed services from potential threats.
Question 48: Which feature allows FortiGate to operate in high availability mode?
A) VLAN configuration
B) HA clustering
C) DNS forwarding
D) DHCP relay
Answer: B
Explanation:
HA clustering enables FortiGate to operate in high availability mode, providing redundancy and automated failover. Multiple FortiGate devices work together as a logical unit, ensuring continuous network protection despite hardware failures. HA configurations eliminate single points of failure in critical network paths.
FortiGate supports active-passive and active-active HA modes. Active-passive mode maintains a primary device handling traffic while secondary devices remain on standby. Upon primary failure, secondary devices assume active roles. Active-active mode distributes traffic across multiple devices for load balancing.
Cluster members synchronize configurations and session tables in real-time. Configuration changes on primary units automatically replicate to secondary units. Session synchronization ensures seamless failover without dropping established connections.
HA clustering requires dedicated heartbeat interfaces monitoring member health. These interfaces exchange keep-alive packets detecting failures within seconds. Multiple heartbeat links provide redundancy preventing false failovers.
Configuration includes assigning priority values determining which device becomes primary. Higher priority devices prefer active roles. Port monitoring tracks interface status, triggering failover when monitored ports fail.
Organizations benefit from improved uptime and simplified maintenance. Hardware upgrades or firmware updates can occur without network downtime. HA clustering is essential for mission-critical network infrastructures.
Question 49: What is the function of firewall address objects in FortiGate?
A) Store passwords
B) Define IP addresses or ranges for policies
C) Configure time settings
D) Manage licenses
Answer: B
Explanation:
Firewall address objects in FortiGate define IP addresses, subnets, or ranges used in security policies and configuration. These objects simplify policy management by using meaningful names instead of IP addresses. Address objects can be reused across multiple policies, ensuring consistency.
Objects support various types including single IP addresses, subnets, IP ranges, FQDN, and geographic locations. Single IP objects represent individual hosts. Subnet objects define network segments using CIDR notation. Range objects specify inclusive IP address ranges.
FQDN address objects resolve domain names to IP addresses dynamically. This capability accommodates cloud services with changing IP addresses. FortiGate periodically resolves FQDNs updating address mappings automatically.
Address groups combine multiple address objects into logical collections. Groups simplify policies by representing multiple addresses with single names. Changes to group membership automatically apply to all referencing policies.
Geographic address objects represent entire countries or regions. These objects enable blocking traffic from specific geographic locations. IP geolocation databases identify source country based on IP addresses.
Address object naming should follow organizational standards for clarity. Descriptive names like “Web-Servers” or “Remote-Office” improve policy readability. Regular review ensures address objects remain current as network changes.
Question 50: Which command displays FortiGate routing table?
A) show route
B) get router info routing-table all

The get router info routing-table all command displays the complete FortiGate routing table including all protocols and route types. This command is essential for troubleshooting routing issues and verifying network connectivity. Output includes destination networks, next-hop addresses, interfaces, and route metrics.
Routing table information reveals how FortiGate forwards traffic to different destinations. Each entry specifies the path packets take based on destination addresses. Understanding the routing table is crucial for diagnosing connectivity problems.
The command displays routes from multiple sources including connected interfaces, static routes, and dynamic routing protocols. Each route includes source identifier showing whether it originated from OSPF, BGP, RIP, or static configuration.
Route metrics determine preferred paths when multiple routes exist to the same destination. Lower metrics indicate preferred routes. Administrators compare metrics understanding route selection logic.
Administrative distance values appear for each route, determining precedence when different routing protocols advertise the same destination. Connected routes have lowest administrative distance, followed by static routes and various dynamic protocols.
Alternative commands include get router info routing-table database to show routes before best-path selection. Protocol-specific commands like get router info ospf route display routes learned through specific protocols. These variations provide targeted troubleshooting information.
Question 51: What is the purpose of UTM profiles in FortiGate?
A) Hardware monitoring
B) Unified threat management inspection
C) Power configuration
D) License management
Answer: B
Explanation:

VLANs provide network segmentation in FortiGate, logically dividing physical networks into isolated broadcast domains. This segmentation improves security by separating different user groups, departments, or security zones. VLANs also enhance performance by reducing broadcast traffic.
FortiGate interfaces support VLAN tagging based on 802.1Q standard. Administrators create VLAN subinterfaces associated with parent physical interfaces. Each VLAN operates as separate interface with unique IP address and security zone.
Network segmentation through VLANs enables implementing security policies between segments. Traffic between VLANs must traverse FortiGate, undergoing policy evaluation and inspection. This architecture provides centralized security enforcement.
VLAN configuration includes specifying VLAN ID and assigning IP addresses. Multiple VLANs can share single physical interface through trunking. This efficiency reduces required physical interfaces in complex networks.
Inter-VLAN routing occurs within FortiGate when multiple VLANs are configured. Firewall policies control traffic flow between VLANs based on security requirements. Some VLAN pairs might allow free communication while others face strict restrictions.
Proper VLAN design considers organizational structure, security requirements, and network topology. Guest networks typically occupy separate VLANs from corporate resources. Sensitive systems like payment processing receive dedicated VLANs with enhanced security controls.
Question 53: What is the function of MAC filtering in FortiGate?
A) Control access based on hardware addresses
B) Email scanning
C) Time configuration
D) Firmware updates
Answer: A
Explanation:
MAC filtering in FortiGate controls network access based on hardware addresses, providing additional security layer beyond IP-based controls. This feature identifies devices by their unique MAC addresses, allowing or denying access accordingly. Organizations use MAC filtering for device-level access control.
The feature operates at layer 2, inspecting Ethernet frame headers. FortiGate maintains lists of permitted or denied MAC addresses. Frames from unknown MAC addresses can be blocked or subjected to additional authentication.
MAC filtering proves particularly useful in wireless environments or for IoT device management. Organizations can whitelist approved devices while blocking unknown equipment. This approach prevents unauthorized device connections.
Configuration includes creating MAC address entries and applying them through policies or WiFi controller settings. Administrators can manually enter MAC addresses or import lists from external sources. Regular updates maintain accurate device inventories.
Limitations include MAC address spoofing, where attackers falsify hardware addresses bypassing filters. MAC filtering should complement rather than replace other security measures. Defense-in-depth strategies combine MAC filtering with stronger authentication mechanisms.
MAC filtering integrates with NAC solutions providing comprehensive access control. Devices undergo health checks and compliance verification before network access. This integration ensures only secure, authorized devices connect.
Question 54: Which protocol does FortiGate use for administrator authentication via external servers?
A) HTTP
B) RADIUS
C) FTP
D) SMTP
Answer: B
Explanation:
FortiGate uses RADIUS protocol for administrator authentication via external servers, enabling centralized credential management and enhanced security. RADIUS integration allows organizations to leverage existing authentication infrastructure for firewall administration. This approach simplifies user management and supports advanced authentication methods.
The protocol operates through client-server communication where FortiGate acts as RADIUS client. When administrators attempt login, FortiGate forwards credentials to RADIUS servers for verification. Server responses indicate authentication success or failure.
RADIUS supports various authentication methods including passwords, tokens, and certificates. Two-factor authentication integrates seamlessly through RADIUS, requiring multiple verification factors. This capability significantly enhances administrative access security.
Organizations configure RADIUS servers specifying server addresses, shared secrets, and authentication ports. Multiple servers provide redundancy ensuring administrative access during server failures. FortiGate tries primary servers before failing over to backups.
Administrator accounts can be defined locally or externally through RADIUS. External accounts leverage RADIUS servers for authentication while maintaining local authorization. This hybrid approach balances centralized management with local control.
RADIUS integration extends beyond administrator authentication to include firewall user authentication and VPN access. Consistent authentication mechanisms across all access methods simplify management and improve security posture.
