Curious about Actual Fortinet Certified Solution Specialist (FCSS_EFW_AD-7.4) Exam Questions?

Correct : A, B

The Internet Service Database (ISDB) in FortiGate is used to enforce content filtering at Layer 3 (Network Layer) and Layer 4 (Transport Layer) of the OSI model by identifying applications based on their predefined IP addresses and ports.

FortiGate has a predefined list of all IPs and ports for specific applications downloaded from FortiGuard:

FortiGate retrieves and updates a predefined list of IPs and ports for different internet services from FortiGuard.

This allows FortiGate to block specific services at Layer 3 and Layer 4 without requiring deep packet inspection.

The ISDB blocks the IP addresses and ports of an application predefined by FortiGuard:

ISDB works by matching traffic to known IP addresses and ports of categorized services.

When an application or service is blocked, FortiGate prevents communication by denying traffic based on its destination IP and port number.

Correct : C

From the Root FortiGate - System Administrator Configuration exhibit:

The AdminSSO account has the super_admin_readonly role.

From the Downstream FortiGate - Security Fabric Settings exhibit:

The Security Fabric role is set to Join Existing Fabric, meaning it will authenticate with the root FortiGate.

SAML Single Sign-On (SSO) is enabled, and the default admin profile is set to super_admin_readonly.

When the AdminSSO user logs into the downstream FortiGate using SSO, the authentication request is sent to the root FortiGate, where AdminSSO has super_admin_readonly permissions. Since the downstream FortiGate inherits this permission through the Security Fabric configuration, the user will be granted super_admin_readonly access.

Correct : D

FortiGate, like other security appliances, cannot analyze encrypted HTTPS traffic unless it decrypts it first. If only certificate inspection is enabled, FortiGate can see the certificate details (such as the domain and issuer) but cannot inspect the actual web content.

To fully analyze the traffic and detect potential malware threats:

Full SSL inspection (Deep Packet Inspection) must be enabled in the SSL/SSH Inspection Profile.

This allows FortiGate to decrypt the HTTPS traffic, inspect the content, and then re-encrypt it before forwarding it to the user.

Without full SSL inspection, threats embedded in encrypted traffic may go undetected.

Correct : B

In an ADVPN (Auto-Discovery VPN) network, a dynamic VPN tunnel is established on-demand between spokes to optimize traffic flow and reduce latency.

Process:

1. Traffic Initiation:

2. Hub Detection:

3. Shortcut Offer:

4. Tunnel Establishment:

Correct : C

When FortiGate processes the first packets of a session, it follows a sequence of steps to determine how the traffic should be handled before establishing a session. The initial step involves:

Access Control List (ACL) checks: Determines if the traffic should be allowed or blocked based on predefined security rules.

Hardware Packet Engine (HPE) inspections: Ensures that packet headers are valid and comply with protocol standards.

IP Integrity Header Checking: Verifies if the IP headers are intact and not malformed or spoofed.

Once these security inspections are completed and the session is validated, FortiGate then installs the session in hardware (if offloading is enabled) or processes it in software.
