Why would you configure an OCSP responder URL in an end-entity certificate?
- A. To identify the end point that a certificate has been assigned to
- B. To designate a server for certificate status checking
- C. To provide the CRL location for the certificate
- D. To designate the SCEP server to use for CRL updates for that certificate
正解：B
解説：
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.
質問 # 39
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 mobile location
- C. Time and FortiAuthenticator serial number
- D. Time and seed
正解：D
解説：
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.
質問 # 40
Which statement about the guest portal policies is true?
- A. All conditions in the policy must match before a user is presented with the guest portal
- B. Conditions in the policy apply only to guest wireless users
- C. Guest portal policies apply only to authentication requests coming from unknown RADIUS clients
- D. Guest portal policies can be used only for BYODs
正解：A
解説：
Guest portal policies are rules that determine when and how to present the guest portal to users who want to access the network. Each policy has a set of conditions that can be based on various factors, such as the source IP address, MAC address, RADIUS client, user agent, or SSID. All conditions in the policy must match before a user is presented with the guest portal. Guest portal policies can apply to any authentication request coming from any RADIUS client, not just unknown ones. They can also be used for any type of device, not just BYODs. They can also apply to wired or VPN users, not just wireless users. Reference: https://docs.fortinet.com/document/fortiauthenticator/6.4/administration-guide/372404/guest-management/372406/portal-policies
質問 # 41
How can a SAML metada file be used?
- A. To import the required IDP configuration
- B. To defined a list of trusted user names
- C. To resolve the IDP realm for authentication
- D. To correlate the IDP address to its hostname
正解：A
解説：
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.
