Question 1

You are a Wi-Fi provider and host multiple domains.

How do you delegate user accounts, user groups and permissions per domain when they are authenticating on a single FortiAuthenticator device?

Answer Options
Correct Answer: A
Explanation

Realms are a way to delegate user accounts, user groups and permissions per domain when they are authenticating on a single FortiAuthenticator device. A realm is a logical grouping of users and groups based on a common attribute, such as a domain name or an IP address range. Realms allow administrators to apply different authentication policies and settings to different groups of users based on their realm membership.

Question 2

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?

Answer Options
Correct Answer: D
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.
