The ‘diagnose vpn tunnel list’ command on FortiGate displays detailed status information about IPsec VPN tunnels, including phase 1 and phase 2 states, uptime, and traffic statistics. Options B, C, and D are not valid FortiGate commands for this purpose. Exact extract: "Use diagnose vpn tunnel list to view the status of IPsec VPN tunnels, including phase 1 and phase 2 details, such as SA status, uptime, and traffic counters."

In a FortiGate HA cluster (active-active or active-passive), if the primary unit fails, a secondary unit automatically takes over as the primary, ensuring continuity of traffic with minimal disruption. Option A is incorrect as traffic continues, C is incorrect as the mode doesn’t change post-failure, and D is unrelated. Exact extract: "In a FortiGate HA cluster, if the primary unit fails, a secondary unit is elected as the new primary, taking over all roles to maintain traffic flow and session continuity."

FortiGate operates on a default-deny principle; if a packet does not match any firewall policy, it is dropped to ensure security. No forwarding (A), IPS processing (C), or automatic allowing (D) occurs without a matching policy. Exact extract: "FortiGate uses a default-deny approach; packets that do not match any configured firewall policy are dropped to prevent unauthorized traffic."

The ‘diagnose debug flow’ command in FortiGate is used to troubleshoot how packets are processed through firewall policies, showing details like policy matching, NAT, and session handling. It helps identify why packets are allowed or dropped. Option A refers to packet sniffing, B to routing diagnostics, and D to performance monitoring, none of which are the primary function. Exact extract: "The diagnose debug flow command displays the packet flow through FortiGate, including policy matching, NAT, and session details, useful for troubleshooting traffic issues."

When a router, such as a FortiGate, receives a packet with a TTL (Time to Live) of 1, it decrements the TTL to 0, drops the packet, and sends an ICMP Time Exceeded message to the source IP. This prevents infinite loops in routing. Option A is incorrect as TTL is decremented, not incremented; B and D are incorrect as the packet is not forwarded when TTL reaches 0. Exact extract: "When a packet’s TTL reaches 1, the router decrements it to 0, drops the packet, and sends an ICMP Time Exceeded message to the source IP address to prevent routing loops."
