FCSS – Enterprise Firewall Administrator 7.4 — Question 14

Why does the ISDB block layers 3 and 4 of the OSI model when applying content filtering? (Choose two.)

Answer options

• A. FortiGate has a predefined list of all IPs and ports for specific applications downloaded from FortiGuard.
• B. The ISDB blocks the IP addresses and ports of an application predefined by FortiGuard.
• C. The ISDB works in proxy mode, allowing the analysis of packets in layers 3 and 4 of the OSI model.
• D. The ISDB limits access by URL and domain.

Correct answer: A, B

Explanation

The correct answers, A and B, indicate that FortiGate utilizes a predefined list from FortiGuard to identify and restrict specific application traffic at layers 3 and 4. Options C and D are incorrect because they either misrepresent the functionality of the ISDB or focus on URL and domain access limitations rather than the specific blocking of IP addresses and ports.
