NSE6_FAC-6.4 Exam Questions and Answers

QUESTION: 6

Which network configuration is required when deploying FortiAuthenticator for portal services?

FortiAuthenticator must have the REST API access enable on port1
One of the DNS servers must be a FortiGuard DNS server
Fortigate must be setup as default gateway for FortiAuthenticator
Policies must have specific ports open between FortiAuthenticator and the authentication clients

Answer(s): D

Explanation:

When deploying FortiAuthenticator for portal services, such as guest portal, sponsor portal, user portal or FortiToken activation portal, the network configuration must allow specific ports to be open between FortiAuthenticator and the authentication clients. These ports are:

TCP 80 for HTTP access

TCP 443 for HTTPS access

TCP 389 for LDAP access

TCP 636 for LDAPS access

UDP 1812 for RADIUS authentication

UDP 1813 for RADIUS accounting

QUESTION: 7

You are a FortiAuthenticator administrator for a large organization. Users who are configured to use FortiToken 200 for two-factor authentication can no longer authenticate. You have verified that only the users with two-factor authentication are experiencing the issue.

What can cause this issue?

FortiToken 200 license has expired
One of the FortiAuthenticator devices in the active-active cluster has failed
Time drift between FortiAuthenticator and hardware tokens
FortiAuthenticator has lost contact with the FortiToken Cloud servers

Answer(s): C

Explanation:

One possible cause of the issue is time drift between FortiAuthenticator and hardware tokens. Time drift occurs when the internal clocks of FortiAuthenticator and hardware tokens are not synchronized. This can result in mismatched one-time passwords (OTPs) generated by the hardware tokens and expected by FortiAuthenticator. To prevent this issue, FortiAuthenticator provides a time drift tolerance option that allows a certain number of seconds of difference between the clocks.

QUESTION: 8

Why would you configure an OCSP responder URL in an end-entity certificate?

To designate the SCEP server to use for CRL updates for that certificate
To identify the end point that a certificate has been assigned to
To designate a server for certificate status checking
To provide the CRL location for the certificate

Answer(s): C

Explanation:

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.

QUESTION: 9

An administrator wants to keep local CA cryptographic keys stored in a central location.

Which FortiAuthenticator feature would provide this functionality?

SCEP support
REST API
Network HSM
SFTP server

Answer(s): C

Explanation:

Network HSM is a feature that allows FortiAuthenticator to keep local CA cryptographic keys stored in a central location. HSM stands for Hardware Security Module, which is a physical device that provides secure storage and generation of cryptographic keys. Network HSM allows FortiAuthenticator to use an external HSM device to store and manage the private keys of its local CAs, instead of storing them locally on the FortiAuthenticator device.

QUESTION: 10

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

Service provider contacts idendity provider, idendity provider validates principal for service provider, service provider establishes communication with principal
Principal contacts idendity provider and is redirected to service provider, principal establishes connection with service provider, service provider validates authentication with identify provider
Principal contacts service provider, service provider redirects principal to idendity provider, after succesfull authentication identify provider redirects principal to service provider
Principal contacts idendity provider and authenticates, identity provider relays principal to service provider after valid authentication

Answer(s): C

Explanation:

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.
