Question #1
Which two protocols are the default management access protocols for administrative access for FortiAuthenticator? (Choose two)
Select 2 answers.
Please select an optionIncorrectCorrect answer: B, C
HTTPS and SSH are the default management access protocols for administrative access for FortiAuthenticator. HTTPS allows administrators to access the web- based GUI of FortiAuthenticator using a web browser and a secure connection. SSH allows administrators to access the CLI of FortiAuthenticator using an SSH client and an encrypted connection. Both protocols require the administrator to enter a valid username and password to log in.

Why would you configure an OCSP responder URL in an end-entity certificate?
Please select an optionIncorrectCorrect answer: C
An OCSP responder URL in an end-entity certificate is used to designate a server for certificate status checking. OCSP stands for Online Certificate Status Protocol, which is a method of verifying whether a certificate is valid or revoked in real time. An OCSP responder is a server that responds to OCSP requests from clients with the status of the certificate in question. The OCSP responder URL in an end-entity certificate points to the location of the OCSP responder that can provide the status of that certificate. References: https://docs.fortinet.com/document/fortiauthenticator/6.4.0/administration-guide/906179/certificate-management
Was this answer correct?Question #3
Which three of the following can be used as SSO sources? (Choose three)
Select 3 answers.
Please select an optionIncorrectCorrect answer: A, D, E
FortiAuthenticator supports various SSO sources that can provide user identity information to other devices in the network, such as FortiGate firewalls or FortiAnalyzer log servers. Some of the supported SSO sources are: FortiClient SSO Mobility Agent: A software agent that runs on Windows devices and sends user login information to FortiAuthenticator. FortiGate: A firewall device that can send user login information from various sources, such as FSSO agents, captive portals, VPNs, or LDAP servers, to FortiAuthenticator. RADIUS accounting: A protocol that can send user login information from RADIUS servers or clients, such as wireless access points or VPN concentrators, to FortiAuthenticator. SSH sessions and FortiAuthenticator in SAML SP role are not valid SSO sources because they do not provide user identity information to other devices in the network. References: https://docs.fortinet.com/document/fortiauthenticator/6.4/administration-guide/372410/single-sign-on
Was this answer correct?Question #4
An administrator is integrating FortiAuthenticator with an existing RADIUS server with the intent of eventually replacing the RADIUS server with FortiAuthenticator. How can FortiAuthenticator help facilitate this process?
Please select an optionIncorrectCorrect answer: A
FortiAuthenticator can help facilitate the process of replacing an existing RADIUS server by enabling learning mode in the RADIUS server configuration. This allows FortiAuthenticator to learn user credentials from the existing RADIUS server and store them locally for future authentication requests2. This way, FortiAuthenticator can gradually take over the role of the RADIUS server without disrupting the user experience. References: 2 https://docs.fortinet.com/document/fortiauthenticator/6.4.0/administration-guide/906179/radiu
Was this answer correct?Question #5
A system administrator wants to integrate FortiAuthenticator with an existing identity management system with the goal of authenticating and deauthenticating users into FSSO. What feature does FortiAuthenticator offer for this type of integration?
Please select an optionIncorrectCorrect answer: C
REST API is a feature that allows FortiAuthenticator to integrate with an existing identity management system with the goal of authenticating and deauthenticating users into FSSO. REST API stands for Representational State Transfer Application Programming Interface, which is a method of exchanging data between different systems using HTTP requests and responses. FortiAuthenticator provides a REST API that can be used by external systems to perform various actions, such as creating, updating, deleting, or querying users and groups, or sending FSSO logon or logoff events. References: https://docs.fortinet.com/document/fortiauthenticator/6.4.0/administration-guide/906179/rest-api
Was this answer correct?Question #6
How can a SAML metada file be used?
Please select an optionIncorrectCorrect answer: B
A SAML metadata file can be used to import the required IDP configuration for SAML service provider mode. A SAML metadata file is an XML file that contains information about the identity provider (IDP) and the service provider (SP), such as their entity IDs, endpoints, certificates, and attributes. By importing a SAML metadata file from the IDP, FortiAuthenticator can automatically configure the necessary settings for SAML service provider mode. References: https://docs.fortinet.com/document/fortiauthenticator/6.4.0/administration-guide/906179/saml-service-provider#
Was this answer correct?Question #7
When you are setting up two FortiAuthenticator devices in active-passive HA, which HA role must you select on the master FortiAuthenticator?
Please select an optionIncorrectCorrect answer: A
When you are setting up two FortiAuthenticator devices in active-passive HA, you need to select the active-passive master role on the master FortiAuthenticator device. This role means that the device will handle all requests and synchronize data with the slave device until a failover occurs. The slave device must be configured as an active-passive slave role. The other roles are used for different HA modes, such as standalone (no HA), cluster (active-active), or load balancing (active-active with load balancing). References: https://docs.fortinet.com/document/fortiauthenticator/6.4/administration-guide/372411/high-availability
Was this answer correct?Question #8
Which two capabilities does FortiAuthenticator offer when acting as a self-signed or local CA? (Choose two)
Select 2 answers.
Please select an optionIncorrectCorrect answer: B, D
FortiAuthenticator can act as a self-signed or local CA that can issue certificates to users, devices, or other CAs. It can also import other CA certificates and CRLs to trust them and validate their certificates. It can also create, sign, and revoke X.509 certificates for various purposes, such as VPN authentication, web server encryption, or wireless security. It cannot validate other CA CRLs using OCSP or merge local and remote CRLs using SCEP because these are protocols that require communication with external CAs. References: https://docs.fortinet.com/document/fortiauthenticator/6.4/administration-guide/372408/certificate- management
Was this answer correct?Question #9
Which two statement about the RADIUS service on FortiAuthenticator are true? (Choose two)
Select 2 answers.
Please select an optionIncorrectCorrect answer: B, D
Two statements about the RADIUS service on FortiAuthenticator are true: RADIUS users can be migrated to LDAP users using the RADIUS learning mode feature. This feature allows FortiAuthenticator to learn user credentials from an existing RADIUS server and store them locally as LDAP users for future authentication requests. FortiAuthenticator answers only to RADIUS clients that are registered with FortiAuthenticator. A RADIUS client is a device that sends RADIUS authentication or accounting requests to FortiAuthenticator. A RADIUS client must be added and configured on FortiAuthenticator before it can communicate with it. References: https://docs.fortinet.com/document/fortiauthenticator/6.4.0/administration-guide/906179/radius-service
Was this answer correct?Question #10
