Question 1

When you are setting up two FortiAuthenticator devices in active-passive HA, which HA role must you select on the master FortiAuthenticator?



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).

Question 2

When generating a TOTP for two-factor authentication, what two pieces of information are used by the algorithm to generate the TOTP?



Answer : B

TOTP stands for Time-based One-time Password, which is a type of OTP that is generated based on two pieces of information: time and seed. The time is the current timestamp that is synchronized between the client and the server. The seed is a secret key that is shared between the client and the server. The TOTP algorithm combines the time and the seed to generate a unique and short-lived OTP that can be used for two-factor authentication.


Question 3

Which option correctly describes an SP-initiated SSO SAML packet flow for a host without a SAML assertion?



Answer : C

SP-initiated SSO SAML packet flow for a host without a SAML assertion is as follows:

Principal contacts service provider, requesting access to a protected resource.

Service provider redirects principal to identity provider, sending a SAML authentication request.

Principal authenticates with identity provider using their credentials.

After successful authentication, identity provider redirects principal back to service provider, sending a SAML response with a SAML assertion containing the principal's attributes.

Service provider validates the SAML response and assertion, and grants access to the principal.


Question 4

At a minimum, which two configurations are required to enable guest portal services on FortiAuthenticator? (Choose two)



Answer : A, B

enable guest portal services on FortiAuthenticator, you need to configure a portal policy that defines the conditions for presenting the guest portal to users and the authentication methods to use. You also need to configure at least one post-login service that defines what actions to take after a user logs in successfully, such as sending an email confirmation, assigning a VLAN, or creating a user account. Configuring a RADIUS client or an external authentication portal are optional steps that depend on your network setup and requirements.

Question 5

What happens when a certificate is revoked? (Choose two)



Answer : B, C

When a certificate is revoked, it means that it is no longer valid and should not be trusted by any entity. Revoked certificates are automatically added to the certificate revocation list (CRL) which is published by the issuing CA and can be checked by other parties. If a CA certificate is revoked, all certificates signed by that CA are also revoked and added to the CRL. Revoked certificates can be reinstated if the reason for revocation is resolved, such as a compromised private key being recovered or a misissued certificate being corrected. External CAs do not query FortiAuthenticator for revoked certificates, but they can use protocols such as SCEP or OCSP to exchange certificate information with FortiAuthenticator.

Question 6

Which two statement about the RADIUS service on FortiAuthenticator are true? (Choose two)



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.


Question 7

Which statement about captive portal policies is true, assuming a single policy has been defined?



Answer : B

Captive portal policies are used to define the conditions and settings for presenting a captive portal to users who need to authenticate before accessing the network. A captive portal policy consists of a set of conditions and a set of actions. The conditions can be based on various attributes, such as source IP address, MAC address, user group, device type, or RADIUS client. The actions can include redirecting the user to a specific portal, applying a specific authentication method, or assigning a specific VLAN or firewall policy. A single policy can have multiple conditions, and all conditions in the policy must match before a user is presented with the captive portal.
