NEW QUESTION # 12
Which EAP method is known as the outer authentication method?

A. PEAP
B. EAP-GTC
C. MSCHAPV2
D. EAP-TLS

Answer: A

Explanation:
PEAP is known as the outer authentication method because it establishes a secure tunnel between the client and the server using TLS. The inner authentication method, such as EAP-GTC, EAP-TLS, or MSCHAPV2, is then used to authenticate the client within the tunnel.

NEW QUESTION # 13
An administrator has an active directory (AD) server integrated with FortiAuthenticator. They want members of only specific AD groups to participate in FSSO with their corporate FortiGate firewalls.
How does the administrator accomplish this goal?

A. Configure a domain groupings list to identify the desired AD groups.
B. Configure a FortiGate filter on FortiAuthenticatoc
C. Configure SSO groups and assign them to FortiGate groups.
D. Configure fine-grained controls on FortiAuthenticator to designate AD groups.

Answer: C

Explanation:
To allow members of only specific AD groups to participate in FSSO with their corporate FortiGate firewalls, the administrator can configure SSO groups and assign them to FortiGate groups. SSO groups are groups of users or devices that are defined on FortiAuthenticator based on various criteria, such as user group membership, source IP address, MAC address, or device type. FortiGate groups are groups of users or devices that are defined on FortiGate based on various criteria, such as user group membership, firewall policy, or authentication method. By mapping SSO groups to FortiGate groups, the administrator can control which users or devices can access the network resources protected by FortiGate.

NEW QUESTION # 14
Why would you configure an OCSP responder URL in an end-entity certificate?

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

Answer: 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.

NEW QUESTION # 15
Which option correctly describes an SP-initiated SSO SAML packet flow for a host without a SAML assertion?

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

Answer: D

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.

NEW QUESTION # 16
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?

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

Answer: 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.

NEW QUESTION # 17
Which of the following is an OATH-based standard to generate event-based, one-time password tokens?

A. SOTP
B. OLTP
C. TOTP
D. HOTP

Answer: D

Explanation:
Reference:
HOTP stands for HMAC-based One-time Password, which is an OATH-based standard to generate event-based OTP tokens. HOTP uses a cryptographic hash function called HMAC (Hash-based Message Authentication Code) to generate OTPs based on two pieces of information: a secret key and a counter. The counter is incremented by one after each OTP generation, creating an event-based sequence of OTPs.

NEW QUESTION # 18
Which two features of FortiAuthenticator are used for EAP deployment? (Choose two)

A. LDAP server
B. Certificate authority
C. MAC authentication bypass
D. RADIUS server

Answer: B,D

Explanation:
Two features of FortiAuthenticator that are used for EAP deployment are certificate authority and RADIUS server. Certificate authority allows FortiAuthenticator to issue and manage digital certificates for EAP methods that require certificate-based authentication, such as EAP-TLS or PEAP-EAP-TLS. RADIUS server allows FortiAuthenticator to act as an authentication server for EAP methods that use RADIUS as a transport protocol, such as EAP-GTC or PEAP-MSCHAPV2.

NEW QUESTION # 20
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?

A. By configuring the RADIUS accounting proxy
B. By enabling learning mode in the RADIUS server configuration
C. By enabling automatic REST API calls from the RADIUS server
D. By importing the RADIUS user records

Answer: B

Explanation:
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.

NEW QUESTION # 21
Which statement about the assignment of permissions for sponsor and administrator accounts is true?

A. Administrator capabilities are assigned by applying permission sets to admin groups.
B. Sponsor permissions are assigned using group settings.
C. Only administrator accounts permissions are assigned using admin profiles.
D. Both sponsor and administrator account permissions are assigned using admin profiles.

Answer: D

Explanation:
Both sponsor and administrator account permissions are assigned using admin profiles. An admin profile is a set of permissions that defines what actions an administrator or a sponsor can perform on FortiAuthenticator. An admin profile can be assigned to an admin group or an individual admin user. A sponsor is a special type of admin user who can create and manage guest accounts on behalf of other users.

NEW QUESTION # 22
When generating a TOTP for two-factor authentication, what two pieces of information are used by the algorithm to generate the TOTP?

A. UUID and time
B. Time and FortiAuthenticator serial number
C. Time and seed
D. Time and mobile location

Answer: C

Explanation:
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.

NEW QUESTION # 23
Which FSSO discovery method transparently detects logged off users without having to rely on external features such as WMI polling?

A. DC Polling
B. Windows AD polling
C. FortiClient SSO Mobility Agent
D. Radius Accounting

Answer: C

Explanation:
FortiClient SSO Mobility Agent is a FSSO discovery method that transparently detects logged off users without having to rely on external features such as WMI polling. FortiClient SSO Mobility Agent is a software agent that runs on Windows devices and communicates with FortiAuthenticator to provide FSSO information. The agent can detect user logon and logoff events without using WMI polling, which can reduce network traffic and improve performance.

TCP 636 for LDAPS access
UDP 1812 for RADIUS authentication
UDP 1813 for RADIUS accounting

NEW QUESTION # 25
Which two statements about the EAP-TTLS authentication method are true? (Choose two)

A. Uses digital certificates only on the server side
B. Support a port access control (wired) solution only
C. Requires an EAP server certificate
D. Uses mutual authentication

Answer: A,C

Explanation:
EAP-TTLS is an authentication method that uses digital certificates only on the server side to establish a secure tunnel between the server and the client. The client does not need a certificate but can use any inner authentication method supported by the server, such as PAP, CHAP, MS-CHAP, or EAP-MD5. EAP-TTLS requires an EAP server certificate that is issued by a trusted CA and installed on the FortiAuthenticator device acting as the EAP server. EAP-TTLS supports both wireless and wired solutions for port access control. Reference: https://docs.fortinet.com/document/fortiauthenticator/6.4/administration-guide/372412/eap-ttls

NEW QUESTION # 26
Which two statement about the RADIUS service on FortiAuthenticator are true? (Choose two)

A. Only local users can be authenticated through RADIUS
B. RADIUS users can migrated to LDAP users
C. Two-factor authentication cannot be enforced when using RADIUS authentication
D. FortiAuthenticator answers only to RADIUS client that are registered with FortiAuthenticator

Answer: B,D

Explanation:
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.

NEW QUESTION # 27
Which method is the most secure way of delivering FortiToken data once the token has been seeded?

A. Automatic token generation using FortiAuthenticator
B. Shipment of the seed files on a CD using a tamper-evident envelope
C. Online activation of the tokens through the FortiGuard network
D. Using the in-house token provisioning tool

Answer: C

Explanation:
Online activation of the tokens through the FortiGuard network is the most secure way of delivering FortiToken data once the token has been seeded because it eliminates the risk of seed files being compromised during transit or storage. The other methods involve physical or manual delivery of seed files which can be intercepted, lost, or stolen. Reference: https://docs.fortinet.com/document/fortiauthenticator/6.4/administration-guide/372403/fortitoken

NEW QUESTION # 28
