Question 1 (Topic 1)

A network administrator is reviewing firewall policies in both Interface Pair View and By Sequence View. The policies appear in a different order in each view. Why is the policy order different in these two views?

Select an option, then click Submit answer.

○ Interface Pair View sorts policies based on matching interfaces, while By Sequence View shows the actual processing order of rules.
○ By Sequence View groups policies based on rule priority, while Interface Pair View always follows the order of traffic logs.
○ The firewall dynamically reorders policies in Interface Pair View based on recent traffic patterns, but By Sequence View remains static.
○ Policies in Interface Pair View are prioritized by security levels, while By Sequence View strictly follows the administrator’s manual ordering.

Reference / correct answer:

Interface Pair View sorts policies based on matching interfaces, while By Sequence View shows the actual processing order of rules.

Most accepted answer: A. Interface Pair View sorts policies based on matching interfaces, while By Sequence View shows the actual processing order of rules.

Community votes: A=3

Selected Answer: A FortiGate allows you to view firewall policies in two main ways: 1. Interface Pair View In this view, policies are grouped by interface pair (Incoming Interface → Outgoing Interface). 2. By Sequence View In this view, all policies appear in a single list, exactly in the order in which FortiGate evaluates them. upvoted 1 times

Selected Answer: A The Core Concept: Top-Down Evaluation FortiGate evaluates firewall policies top-down. When a packet enters the firewall, FortiOS checks it against the very first policy on the list. If it matches, the firewall applies the action (Accept or Deny) and stops looking. If it doesn't match, it moves to the second policy, and so on, until it hits the implicit deny rule at the bottom. upvoted 1 times

Selected Answer: A Interface Pair View Groups policies by incoming → outgoing interface pairs Not actual execution order By Sequence View Shows top-to-bottom order This is the real processing order FortiGate uses upvoted 1 times

Question 2 (Topic 1)

An administrator wants to configure dead peer detection (DPD) on IPsec VPN for detecting dead tunnels. The requirement is that FortiGate sends DPD probes only when there is no inbound traffic. Which DPD mode on FortiGate meets this requirement?

Select an option, then click Submit answer.

○ On Demand
○ Enabled
○ On Idle
○ Disabled

Reference / correct answer:

On Idle

Most accepted answer: C. On Idle

Community votes: A=5, C=6

Selected Answer: A Disable: FortiGate never sends DPD probes to the remote peer, but responds to DPD probes received On-idle: FortiGate sends DPD probes when no traffic is observed in the tunnel (outbound or inbound). On-demand: FortiGate sends DPD probes if there is only outbound traffic through the tunnel, but no inbound. On-demand is the default setting. upvoted 9 times

Selected Answer: C on-idle sends probes when the tunnel has no traffic in either direction upvoted 1 times

Selected Answer: A Answer is On-Demand when there is no Inbound connection. On-idle is for when there is no inbound/outbound.Disabled option is that the FW will only respond to DPD probes and is like listener. upvoted 2 times

Selected Answer: C On Idle → Trigger: lack of inbound traffic → Action: send DPD probes ✔ This directly matches the requirement On Demand → Trigger: outbound traffic is sent but no response is received → Action: send DPD probes ✖ This does not trigger just because the tunnel is quiet upvoted 1 times

Selected Answer: C On Idle (Correct) Sends probes ONLY when tunnel is idle (no traffic) Exact match with requirement upvoted 1 times

Question 3 (Topic 1)

You have configured an application control profile, set peer-o-peer traffic to Block under the Categories tab, and applied it to the firewall policy. However, you peer-to-peer traffic on known ports is passing through the FortiGate without being blocked. What FortiGate settings should you check to resolve this issue?

Select an option, then click Submit answer.

○ Replacement Messages for UDP-based Applications
○ Network Protocol Enforcement
○ Application and Filter Overrides
○ FortiGuard category ratings

Reference / correct answer:

Network Protocol Enforcement

Most accepted answer: B. Network Protocol Enforcement

Community votes: B=6, C=2

Selected Answer: C Overrides take precedence over category‑based actions. So even if the P2P category is set to Block Network Protocol Enforcement This feature checks protocol compliance (e.g., HTTP on port 80). It does not override application control decisions. upvoted 1 times

Selected Answer: B The answer is B, but you should check 'C' too in real life (overrides can bypass category actions), but it is not the primary reason for traffic on known ports bypassing the category block. upvoted 2 times

Selected Answer: B Network Protocol Enforcement settings control how FortiGate inspects and enforces protocols on traffic, including peer-to-peer applications on known ports. If not properly enabled, peer-to-peer traffic may bypass blocking despite the application control profile. upvoted 2 times

Selected Answer: B You have already: Blocked peer-to-peer (P2P) under Application Control Categories Applied the profile to the firewall policy Yet traffic is still passing because: 👉 P2P applications can use well-known ports (e.g., TCP 80/443) to bypass detection 👉 Without deeper inspection, FortiGate may classify this traffic as regular web traffic instead of P2P Why Network Protocol Enforcement fixes this: It ensures that traffic on a port actually matches the expected protocol Example: If P2P traffic tries to use port 80 (HTTP) but is not truly HTTP → it gets flagged and blocked This prevents application evasion techniques upvoted 2 times

Selected Answer: B The correct answer is: B. Network Protocol Enforcement Explanation: Even though you configured an Application Control profile to block peer-to-peer (P2P) traffic, FortiGate may still allow traffic if it is using well-known ports (e.g., HTTP/HTTPS) and is not being properly identified as P2P. Network Protocol Enforcement ensures that traffic is validated against its expected protocol behavior, not just the port number. Without it, P2P applications can bypass detection by tunneling over common ports like TCP/80 or TCP/443. Enabling this setting forces FortiGate to inspect and correctly classify the application, allowing the block action to take effect. upvoted 2 times
