An enterprise customer with asymmetric WAN links (1 Gbps outbound, 100 Mbps inbound) is experiencing dropped SSL/TLS connections during deep packet inspection. The security team wants to maintain full certificate-based SSL inspection on client-facing connections while minimizing performance impact. Which SSL inspection strategy and configuration should you recommend?
Answer(s): A
Certificate inspection mode combined with SNI checking is the optimal strategy for this scenario. Certificate inspection validates the certificate chain and subject names using SNI matching without performing full man-i--the-middle decryption of application data. This significantly reduces CPU and memory overhead while preserving visibility of certificate anomalies. SNI checking is particularly valuable because it verifies that the server certificate's subject matches the SNI value sent by the client, catching potential SSL/TLS mismatches.Option B misunderstands the asymmetry problem: full inspection under bandwidth constraints still causes CPU bottlenecks and packet drops, and MSS adjustments do not address the inspection overhead. Option C removes visibility entirely, which does not meet the security requirement. Option D incorrectly suggests using HTTP code injection for SSL inspection (HTTP injection applies to HTTP responses, not SSL enrollment notifications) and still requires full inspection which causes the same performance problems.
Which statement about protocol options is true?
Answer(s): D
Without specific answer options provided, the statement about protocol options cannot be evaluated. Protocol options in FortiGate firewalls generally relate to how different network protocols (TCP, UDP, ICMP, etc.) are handled in security policies. A true statement would address characteristics such as application-level handling, performance considerations, or compatibility aspects.
MULTIPLE CHOICEWhich two statements about conserve mode are true? (Choose two.)
Answer(s): B,C
Without the specific answer options, the two true statements about conserve mode cannot be identified. Conserve mode in FortiGate is a resource-protection feature that activates when system resources are low. True statements typically address that conserve mode: reduces concurrent session limits, disables non-essential services, impacts new connection establishment, or helps prevent system resource exhaustion during high-load conditions.
Refer to the exhibit, which contains partial output from an IKE real-time debug.The administrator does not have access to the remote gateway.Based on the debug output, which configuration change the administrator make to the local gateway to resolve the phase 1 negotiation error?
The exhibit with the IKE real-time debug output is not provided. Phase 1 negotiation errors typically stem from mismatches in: encryption algorithms, authentication methods, DH groups, or hash algorithms. Without seeing the specific debug output, the exact configuration change needed cannot be determined. The administrator would need to ensure the local gateway's phase 1 settings match what the remote gateway expects (or vice versa if only the local side can be modified).
MULTIPLE CHOICEWhich three common FortiGate-to-collector-agent connectivity issues can you identify using the FSSO real-time debug? (Choose three.)
Answer(s): B,C,D
Without access to specific answer options, the three FSSO connectivity issues cannot be confirmed. Common FortiGate-to-FSSO-collector-agent connectivity issues typically identifiable via real-time debug include: network connectivity problems (firewall blocking, routing issues), port configuration errors, authentication failures, DNS resolution problems, or collector agent service not running.
