Question 80

A security architect enables every IPS signature on a sensitive OT segment without testing false-positive and latency impacts on legacy industrial protocols. Which FortiOS 7.6 configuration or corrective action is MOST appropriate?

  1. Apply FortiOS antivirus profiles and protocol options in the supported inspection mode on the relevant firewall policies, with suitable FortiGuard definitions and HTTPS visibility.
  2. Build a FortiGate intrusion prevention sensor using supported signature filters, action overrides and protected-application context, then attach it to the correct policy.
  3. Apply narrowly scoped, auditable SSL-inspection exclusions for supported certificate-pinned or regulated applications without disabling inspection for every other destination.
  4. Measure FortiOS IPS engine and appliance resource load under representative traffic before changing signature sets or SSL inspection scope, keeping protection while isolating bottlenecks.

Explanation

Correct Answer

B:

Build a FortiGate intrusion prevention sensor using supported signature filters, action overrides and protected-application context, then attach it to the correct policy. This directly addresses the FortiOS configuration or response required by the case. Signature severity alone does not guarantee relevance; a disabled or monitor-only IPS rule may log threats without blocking, and encrypted payloads need appropriate inspection. Verify with: Inspect IPS sensor filter severity/category, signature IDs, action selection, policy assignment, SSL visibility and actual IPS event logs. Scenario: A security architect enables every IPS signature on a sensitive OT segment without testing false-positive and latency impacts on legacy industrial protocols.

Incorrect Answers

A:

Apply FortiOS antivirus profiles and protocol options in the supported inspection mode on the relevant firewall policies, with suitable FortiGuard definitions and HTTPS visibility. This addresses Antivirus profile scanning modes and supported protocol boundaries, but not the principal task of the described flow. An antivirus profile can only scan content visible in its inspection path and within supported protocol or size limits; a scanner configured but unattached is ineffective. The better fit is: Build a FortiGate intrusion prevention sensor using supported signature filters, action overrides and protected-application context, then attach it to the correct policy. Scenario: A security architect enables every IPS signature on a sensitive OT segment without testing false-positive and latency impacts on legacy industrial protocols.

C:

Apply narrowly scoped, auditable SSL-inspection exclusions for supported certificate-pinned or regulated applications without disabling inspection for every other destination. This addresses Targeted SSL inspection exclusions and privacy controls, but not the principal task of the described flow. Broad category-level SSL exemptions can create large visibility gaps; an exception should be limited to the actual affected flow and justified by policy. The better fit is: Build a FortiGate intrusion prevention sensor using supported signature filters, action overrides and protected-application context, then attach it to the correct policy. Scenario: A security architect enables every IPS signature on a sensitive OT segment without testing false-positive and latency impacts on legacy industrial protocols.

D:

Measure FortiOS IPS engine and appliance resource load under representative traffic before changing signature sets or SSL inspection scope, keeping protection while isolating bottlenecks. This addresses IPS process CPU demand and inspection capacity, but not the principal task of the described flow. An IPS workload may be CPU-bound on a particular model or traffic mix, and disabling all sensors is not a diagnosis of the expensive signature or protocol path. The better fit is: Build a FortiGate intrusion prevention sensor using supported signature filters, action overrides and protected-application context, then attach it to the correct policy. Scenario: A security architect enables every IPS signature on a sensitive OT segment without testing false-positive and latency impacts on legacy industrial protocols.

Question 81

A technician updates an address group with a broad 10.0.0.0/8 range to fix one subnet and unexpectedly permits all office subnets through existing rules. Which TWO complementary choices provide the appropriate response AND the key evidence for verifying it? Select TWO.

  1. Examine original and translated tuple in the FortiOS session table, chosen policy ID, VIP match, SD-WAN route, source interface and TCP handshake packets.
  2. Maintain precise address objects, FQDN objects, service definitions and supported interface zones so FortiGate rules express intended business segments rather than accidental broad matches.
  3. Internal clients resolve and reach the intended server consistently without bypassing stateful inspection or exposing additional services.
  4. Combine the correct identity groups, schedules and narrowly scoped services in a FortiGate firewall policy, and assess whether active sessions require clearing after rule changes.
  5. Inspect object IP ranges, DNS resolution for dynamic objects, zone membership, custom service ports and protocol, schedule objects and effective policy matches.

Explanation

Correct Answers

B:

Maintain precise address objects, FQDN objects, service definitions and supported interface zones so FortiGate rules express intended business segments rather than accidental broad matches. This directly addresses the FortiOS configuration or response required by the case. A reusable firewall object can expand privileges across multiple policies; zone membership and service port definitions matter independently of the policy name. Verify with: Inspect object IP ranges, DNS resolution for dynamic objects, zone membership, custom service ports and protocol, schedule objects and effective policy matches. This is the implementation portion of the required complementary pair. Scenario: A technician updates an address group with a broad 10.0.0.0/8 range to fix one subnet and unexpectedly permits all office subnets through existing rules.

E:

Inspect object IP ranges, DNS resolution for dynamic objects, zone membership, custom service ports and protocol, schedule objects and effective policy matches. This distinguishes the relevant FortiGate device, session or controller evidence. A reusable firewall object can expand privileges across multiple policies; zone membership and service port definitions matter independently of the policy name. The corresponding action is: Maintain precise address objects, FQDN objects, service definitions and supported interface zones so FortiGate rules express intended business segments rather than accidental broad matches. This is the verification portion of the required complementary pair. Scenario: A technician updates an address group with a broad 10.0.0.0/8 range to fix one subnet and unexpectedly permits all office subnets through existing rules.

Incorrect Answers

A:

Examine original and translated tuple in the FortiOS session table, chosen policy ID, VIP match, SD-WAN route, source interface and TCP handshake packets. This choice relates to Diagnosing translated session return path and policy NAT mismatches, not the complementary implementation-and-evidence pair for the case. Implement: Maintain precise address objects, FQDN objects, service definitions and supported interface zones so FortiGate rules express intended business segments rather than accidental broad matches. Check: Inspect object IP ranges, DNS resolution for dynamic objects, zone membership, custom service ports and protocol, schedule objects and effective policy matches. Scenario: A technician updates an address group with a broad 10.0.0.0/8 range to fix one subnet and unexpectedly permits all office subnets through existing rules.

C:

Internal clients resolve and reach the intended server consistently without bypassing stateful inspection or exposing additional services. This choice relates to NAT hairpin and internal use of public VIP names, not the complementary implementation-and-evidence pair for the case. Implement: Maintain precise address objects, FQDN objects, service definitions and supported interface zones so FortiGate rules express intended business segments rather than accidental broad matches. Check: Inspect object IP ranges, DNS resolution for dynamic objects, zone membership, custom service ports and protocol, schedule objects and effective policy matches. Scenario: A technician updates an address group with a broad 10.0.0.0/8 range to fix one subnet and unexpectedly permits all office subnets through existing rules.

D:

Combine the correct identity groups, schedules and narrowly scoped services in a FortiGate firewall policy, and assess whether active sessions require clearing after rule changes. This choice relates to Schedule, authenticated groups and policy-specific change control, not the complementary implementation-and-evidence pair for the case. Implement: Maintain precise address objects, FQDN objects, service definitions and supported interface zones so FortiGate rules express intended business segments rather than accidental broad matches. Check: Inspect object IP ranges, DNS resolution for dynamic objects, zone membership, custom service ports and protocol, schedule objects and effective policy matches.

Question 82

A technician updates an address group with a broad 10.0.0.0/8 range to fix one subnet and unexpectedly permits all office subnets through existing rules. Which FortiOS 7.6 configuration or corrective action is MOST appropriate?

  1. Maintain precise address objects, FQDN objects, service definitions and supported interface zones so FortiGate rules express intended business segments rather than accidental broad matches.
  2. Isolate FSSO group-policy failures by tracing directory login events to collector tables and FortiGate identity records before altering the protected firewall policy.
  3. Deploy and validate a supported Fortinet Single Sign-On collector and domain-controller event source, ensuring logon events reach the correct FortiGate connector.
  4. Attach supported antivirus, web filter, IPS and application control profiles to the relevant FortiGate firewall policies using a compatible flow-based or proxy-based inspection mode.

Explanation

Correct Answer

A:

Maintain precise address objects, FQDN objects, service definitions and supported interface zones so FortiGate rules express intended business segments rather than accidental broad matches. This directly addresses the FortiOS configuration or response required by the case. A reusable firewall object can expand privileges across multiple policies; zone membership and service port definitions matter independently of the policy name.

Scenario: A technician updates an address group with a broad 10.0.0.0/8 range to fix one subnet and unexpectedly permits all office subnets through existing rules.

Incorrect Answers

B:

Isolate FSSO group-policy failures by tracing directory login events to collector tables and FortiGate identity records before altering the protected firewall policy. This addresses FSSO troubleshooting and authentication connector health, but not the principal task of the described flow. A firewall policy allowing any user is an unsafe substitute for repairing a failed identity collector; authentication is a separate dependency from packet route reachability. The better fit is: Maintain precise address objects, FQDN objects, service definitions and supported interface zones so FortiGate rules express intended business segments rather than accidental broad matches. Scenario: A technician updates an address group with a broad 10.0.0.0/8 range to fix one subnet and unexpectedly permits all office subnets through existing rules.

C:

Deploy and validate a supported Fortinet Single Sign-On collector and domain-controller event source, ensuring logon events reach the correct FortiGate connector. This addresses FSSO collector agent and domain-controller event acquisition, but not the principal task of the described flow. FSSO identifies users from login events rather than interrogating the user at every new TCP connection; a broken collector can leave stale or missing identities. The better fit is: Maintain precise address objects, FQDN objects, service definitions and supported interface zones so FortiGate rules express intended business segments rather than accidental broad matches. Scenario: A technician updates an address group with a broad 10.0.0.0/8 range to fix one subnet and unexpectedly permits all office subnets through existing rules.

D:

Attach supported antivirus, web filter, IPS and application control profiles to the relevant FortiGate firewall policies using a compatible flow-based or proxy-based inspection mode. This addresses Security profiles and flow versus proxy inspection boundaries, but not the principal task of the described flow. Security profiles take effect only when an appropriate policy matches and inspection requirements are met; a profile existing in the GUI does not make it globally active. The better fit is: Maintain precise address objects, FQDN objects, service definitions and supported interface zones so FortiGate rules express intended business segments rather than accidental broad matches. Scenario: A technician updates an address group with a broad 10.0.0.0/8 range to fix one subnet and unexpectedly permits all office subnets through existing rules.

Question 83

A datacenter firewall forwards system events yet investigations lack accepted session records because logging is disabled on the rule permitting the application. Which TWO complementary choices provide the appropriate response AND the key evidence for verifying it? Select TWO.

  1. Operators can reach and diagnose both nodes even when traffic fails over, and upgrades maintain a recoverable and healthy cluster state.
  2. Review cloud vNIC and subnet placement, effective cloud routes, source/destination checks where applicable, FortiOS interface addresses, security groups and return-path symmetry.
  3. Select supported memory, local-disk, FortiAnalyzer or syslog destinations for the model and retention requirement, and detect loss of records before storage or forwarding limits are exceeded.
  4. Register FortiGate with the intended FortiAnalyzer instance, permit trusted management connectivity and enable logs on relevant policies and event categories before relying on central investigations.
  5. Inspect FortiAnalyzer registration and authorization, connectivity, device identity, log forwarding state, log types, policy logging settings and timestamps.

Explanation

Correct Answers

D:

Register FortiGate with the intended FortiAnalyzer instance, permit trusted management connectivity and enable logs on relevant policies and event categories before relying on central investigations. This directly addresses the FortiOS configuration or response required by the case. A healthy route to FortiAnalyzer does not mean the device has been authorized, that the right log categories are enabled, or that records are arriving. Verify with: Inspect FortiAnalyzer registration and authorization, connectivity, device identity, log forwarding state, log types, policy logging settings and timestamps. This is the implementation portion of the required complementary pair. Scenario: A datacenter firewall forwards system events yet investigations lack accepted session records because logging is disabled on the rule permitting the application.

E:

Inspect FortiAnalyzer registration and authorization, connectivity, device identity, log forwarding state, log types, policy logging settings and timestamps. This distinguishes the relevant FortiGate device, session or controller evidence.

B:

Review cloud vNIC and subnet placement, effective cloud routes, source/destination checks where applicable, FortiOS interface addresses, security groups and return-path symmetry. This choice relates to FortiGate VM in public-cloud route and interface topology, not the complementary implementation-and-evidence pair for the case.

C:

Select supported memory, local-disk, FortiAnalyzer or syslog destinations for the model and retention requirement, and detect loss of records before storage or forwarding limits are exceeded. This choice relates to FortiGate local log storage and reliable export, not the complementary implementation-and-evidence pair for the case.

Question 84

A web browser loads a blocked site over HTTPS, but the security team checks only a generic firewall permit log instead of the associated web filter event. Which TWO complementary choices provide the appropriate response AND the key evidence for verifying it? Select TWO.

  1. Choose FortiOS DNS filtering or web filtering controls based on the traffic path and available request metadata, verifying that protected clients actually use the intended DNS resolver.
  2. A false positive is isolated, resolved with the smallest verified rule change and monitored for recurrence while prohibited applications remain blocked.
  3. Select the supported web filtering profile and inspection mode for the desired FortiGate URL or category enforcement, validating policy attachment and expected traffic visibility.
  4. Review policy flow/proxy mode, web filter profile, SSL inspection depth, web request metadata, FortiGuard rating and matching event logs.
  5. Inspect URL rating lookup, category database update, applied web filter rule, local rating override, browser result and web-filter log.

Explanation

Correct Answers

C:

Select the supported web filtering profile and inspection mode for the desired FortiGate URL or category enforcement, validating policy attachment and expected traffic visibility. This directly addresses the FortiOS configuration or response required by the case. Flow-based and proxy-based features may expose different controls and troubleshooting evidence; a web filter profile cannot enforce unseen encrypted URL paths. Verify with: Review policy flow/proxy mode, web filter profile, SSL inspection depth, web request metadata, FortiGuard rating and matching event logs. This is the implementation portion of the required complementary pair. Scenario: A web browser loads a blocked site over HTTPS, but the security team checks only a generic firewall permit log instead of the associated web filter event.

Question 85

A web filter denies a specific path, but administrators expect a DNS filter to distinguish that path from other pages at the same domain. Which TWO complementary choices provide the appropriate response AND the key evidence for verifying it? Select TWO.

  1. Use FortiGuard website categories and supported rating overrides to enforce approved access policy, documenting exceptions for miscategorized business sites.
  2. Choose FortiOS DNS filtering or web filtering controls based on the traffic path and available request metadata, verifying that protected clients actually use the intended DNS resolver.
  3. Review DNS policy/profile, DNS transport, query logs, client resolver configuration, DoH/DoT behavior, browser HTTPS requests and matching web-filter outcomes.
  4. Known harmless test signatures trigger the expected controlled action and SOC operators can trace detection to file, user, policy and update state.
  5. Review SSL decryption logs, endpoint CA trust, AV protocol scanning, matching policy, file action, exception object and user browser errors.

Explanation

Correct Answers

B:

Choose FortiOS DNS filtering or web filtering controls based on the traffic path and available request metadata, verifying that protected clients actually use the intended DNS resolver. This directly addresses the FortiOS configuration or response required by the case. DNS filtering acts on DNS lookups, not arbitrary HTTP URL paths or already established IP connections, and encrypted DNS may bypass poorly placed resolver controls. Verify with: Review DNS policy/profile, DNS transport, query logs, client resolver configuration, DoH/DoT behavior, browser HTTPS requests and matching web-filter outcomes. This is the implementation portion of the required complementary pair. Scenario: A web filter denies a specific path, but administrators expect a DNS filter to distinguish that path from other pages at the same domain.

Question 86

A DNAT mapping successfully sends SYN packets to the server, but its response leaves through a second FortiGate that has no state for the translated flow. Which FortiOS 7.6 configuration or corrective action is MOST appropriate?

  1. Enable the intended logging options on relevant FortiGate allow and deny policies, then correlate explicit and implicit deny handling with counters and session evidence.
  2. Trace FortiGate SNAT and DNAT changes alongside policy decision and route choice to correct sessions that translate properly outbound but fail on the reverse path.
  3. Publish only approved internal services through FortiGate virtual IP destination NAT mappings and a matching WAN-to-server firewall policy, including appropriate port-forwarding constraints.
  4. Isolate FSSO group-policy failures by tracing directory login events to collector tables and FortiGate identity records before altering the protected firewall policy.

Explanation

Correct Answer

B:

Trace FortiGate SNAT and DNAT changes alongside policy decision and route choice to correct sessions that translate properly outbound but fail on the reverse path. This directly addresses the FortiOS configuration or response required by the case. Firewall session state, NAT mapping and routing are coupled; an asymmetric return path or conflicting central NAT rule can cause failure despite correct outbound translation. Verify with: Examine original and translated tuple in the FortiOS session table, chosen policy ID, VIP match, SD-WAN route, source interface and TCP handshake packets. Scenario: A DNAT mapping successfully sends SYN packets to the server, but its response leaves through a second FortiGate that has no state for the translated flow.

Incorrect Answers

A:

Enable the intended logging options on relevant FortiGate allow and deny policies, then correlate explicit and implicit deny handling with counters and session evidence. This addresses Implicit denial, policy logging and rule hit interpretation, but not the principal task of the described flow. An implicit firewall deny may have different log visibility than an explicit deny; no traffic log is not reliable evidence that a packet never reached the FortiGate. The better fit is: Trace FortiGate SNAT and DNAT changes alongside policy decision and route choice to correct sessions that translate properly outbound but fail on the reverse path. Scenario: A DNAT mapping successfully sends SYN packets to the server, but its response leaves through a second FortiGate that has no state for the translated flow.

C:

Publish only approved internal services through FortiGate virtual IP destination NAT mappings and a matching WAN-to-server firewall policy, including appropriate port-forwarding constraints. This addresses VIP destination NAT and published server policies, but not the principal task of the described flow. Creating a VIP object alone does not allow traffic; a corresponding firewall policy, correct port mapping and valid server route are required. The better fit is: Trace FortiGate SNAT and DNAT changes alongside policy decision and route choice to correct sessions that translate properly outbound but fail on the reverse path. Scenario: A DNAT mapping successfully sends SYN packets to the server, but its response leaves through a second FortiGate that has no state for the translated flow.

Question 87

A remote user moves from a guest Wi-Fi subnet to corporate LAN, but the previous authenticated session state is used to troubleshoot an unexpected policy decision. Which FortiOS 7.6 configuration or corrective action is MOST appropriate?

  1. Isolate FSSO group-policy failures by tracing directory login events to collector tables and FortiGate identity records before altering the protected firewall policy.
  2. Enable the intended logging options on relevant FortiGate allow and deny policies, then correlate explicit and implicit deny handling with counters and session evidence.
  3. Combine the correct identity groups, schedules and narrowly scoped services in a FortiGate firewall policy, and assess whether active sessions require clearing after rule changes.
  4. Publish only approved internal services through FortiGate virtual IP destination NAT mappings and a matching WAN-to-server firewall policy, including appropriate port-forwarding constraints.

Explanation

Correct Answer

C:

Combine the correct identity groups, schedules and narrowly scoped services in a FortiGate firewall policy, and assess whether active sessions require clearing after rule changes. This directly addresses the FortiOS configuration or response required by the case. A scheduled policy or identity filter does not retroactively terminate every established session, and a group match depends on reliable identification of the user's current IP or session. Verify with: Examine user authentication state, configured source user groups, policy schedule, session table, policy ID and log timestamps on the test client. Scenario: A remote user moves from a guest Wi-Fi subnet to corporate LAN, but the previous authenticated session state is used to troubleshoot an unexpected policy decision.

Incorrect Answers

Question 88

A browser starts using QUIC for a streaming service, and operators incorrectly expect an HTTP proxy-only inspection rule to show the same application payload events. Which FortiOS 7.6 configuration or corrective action is MOST appropriate?

  1. Correlate TLS metadata visibility, SNI or certificate names and FortiOS web-filter logs to determine when domain-only versus full-URL controls are technically enforceable.
  2. Choose FortiOS DNS filtering or web filtering controls based on the traffic path and available request metadata, verifying that protected clients actually use the intended DNS resolver.
  3. Evaluate supported TLS interception and QUIC/HTTP3 handling against FortiOS model capacity, application requirements and policy visibility instead of assuming every encrypted protocol follows the same inspection path.
  4. Apply narrowly scoped, auditable SSL-inspection exclusions for supported certificate-pinned or regulated applications without disabling inspection for every other destination.

Explanation

Correct Answer

C:

Evaluate supported TLS interception and QUIC/HTTP3 handling against FortiOS model capacity, application requirements and policy visibility instead of assuming every encrypted protocol follows the same inspection path. This directly addresses the FortiOS configuration or response required by the case. HTTP/3 uses QUIC over UDP and may not follow controls designed only for intercepted HTTPS over TCP; deep inspection consumes resources and capability varies by FortiOS build. Verify with: Compare inspection sessions, CPU/memory usage, negotiated TLS or QUIC transport, certificate inspection logs, policy profile and any explicit protocol-control rule. Scenario: A browser starts using QUIC for a streaming service, and operators incorrectly expect an HTTP proxy-only inspection rule to show the same application payload events.

A:

Correlate TLS metadata visibility, SNI or certificate names and FortiOS web-filter logs to determine when domain-only versus full-URL controls are technically enforceable. This addresses HTTPS web filtering hostname limitations and logging, but not the principal task of the described flow. Certificate inspection does not expose all encrypted HTTP headers and paths; some modern encrypted client protocols reduce metadata availability. The better fit is: Evaluate supported TLS interception and QUIC/HTTP3 handling against FortiOS model capacity, application requirements and policy visibility instead of assuming every encrypted protocol follows the same inspection path. Scenario: A browser starts using QUIC for a streaming service, and operators incorrectly expect an HTTP proxy-only inspection rule to show the same application payload events.

B:

Choose FortiOS DNS filtering or web filtering controls based on the traffic path and available request metadata, verifying that protected clients actually use the intended DNS resolver. This addresses DNS filtering versus web filtering visibility boundaries, but not the principal task of the described flow. DNS filtering acts on DNS lookups, not arbitrary HTTP URL paths or already established IP connections, and encrypted DNS may bypass poorly placed resolver controls. The better fit is: Evaluate supported TLS interception and QUIC/HTTP3 handling against FortiOS model capacity, application requirements and policy visibility instead of assuming every encrypted protocol follows the same inspection path. Scenario: A browser starts using QUIC for a streaming service, and operators incorrectly expect an HTTP proxy-only inspection rule to show the same application payload events.

D:

Apply narrowly scoped, auditable SSL-inspection exclusions for supported certificate-pinned or regulated applications without disabling inspection for every other destination. This addresses Targeted SSL inspection exclusions and privacy controls, but not the principal task of the described flow. Broad category-level SSL exemptions can create large visibility gaps; an exception should be limited to the actual affected flow and justified by policy. The better fit is: Evaluate supported TLS interception and QUIC/HTTP3 handling against FortiOS model capacity, application requirements and policy visibility instead of assuming every encrypted protocol follows the same inspection path. Scenario: A browser starts using QUIC for a streaming service, and operators incorrectly expect an HTTP proxy-only inspection rule to show the same application payload events.

Question 89

A conferencing app moves from standard HTTPS to an alternative UDP port and an administrator assumes the firewall service object alone will identify the application correctly. Which TWO complementary choices provide the appropriate response AND the key evidence for verifying it? Select TWO.

  1. Attach a current FortiGate application control profile to the correct matching firewall policy and assess SSL inspection requirements for applications that use encrypted or unusual ports.
  2. Inspect SSL inspection mode, matched policy, negotiated TLS version, inspected application certificate, session log and target protocol support.
  3. Investigate FortiOS application detection logs and signature revisions before creating narrowly scoped exclusions, ensuring legitimate traffic and policy intent remain visible.
  4. The targeted false positive no longer interrupts an approved service, while exploit attempts retain blocking coverage and traceable alerts.
  5. Check application signature database freshness, policy ID, inspection profile, session protocol, application detection event and decryption scope.

Explanation

Correct Answers

A:

Attach a current FortiGate application control profile to the correct matching firewall policy and assess SSL inspection requirements for applications that use encrypted or unusual ports. This directly addresses the FortiOS configuration or response required by the case. Application detection is not identical to TCP service-port matching; encrypted or evasive traffic can require additional visibility and signature coverage. Verify with: Check application signature database freshness, policy ID, inspection profile, session protocol, application detection event and decryption scope. This is the implementation portion of the required complementary pair. Scenario: A conferencing app moves from standard HTTPS to an alternative UDP port and an administrator assumes the firewall service object alone will identify the application correctly.

E:

Check application signature database freshness, policy ID, inspection profile, session protocol, application detection event and decryption scope. This distinguishes the relevant FortiGate device, session or controller evidence. Application detection is not identical to TCP service-port matching; encrypted or evasive traffic can require additional visibility and signature coverage. The corresponding action is: Attach a current FortiGate application control profile to the correct matching firewall policy and assess SSL inspection requirements for applications that use encrypted or unusual ports. This is the verification portion of the required complementary pair. Scenario: A conferencing app moves from standard HTTPS to an alternative UDP port and an administrator assumes the firewall service object alone will identify the application correctly.

Incorrect Answers

B:

Inspect SSL inspection mode, matched policy, negotiated TLS version, inspected application certificate, session log and target protocol support. This choice relates to FortiGate certificate inspection versus full SSL/SSH inspection, not the complementary implementation-and-evidence pair for the case.

Question 90

A cluster fails over during a planned maintenance test, and investigators notice the new primary lacks the expected active-session state for an inspected flow. Which TWO complementary choices provide the appropriate response AND the key evidence for verifying it? Select TWO.

  1. Inspect FortiAnalyzer registration and authorization, connectivity, device identity, log forwarding state, log types, policy logging settings and timestamps.
  2. Only appropriately enrolled and authenticated endpoints reach approved applications, with denied or noncompliant clients producing interpretable policy evidence.
  3. Enable and validate supported FGCP session synchronization and session-pickup behavior appropriate to traffic type and device capability, with realistic application failover exercises.
  4. Configure compatible FortiGate peers as an FGCP high-availability cluster with appropriate heartbeat interfaces, group identity, matching licenses and tracked interfaces.
  5. Examine session-pickup configuration, cluster synchronization, monitored-link state, active sessions, NAT state, failover timing and traffic results.

Explanation

Correct Answers

C:

Enable and validate supported FGCP session synchronization and session-pickup behavior appropriate to traffic type and device capability, with realistic application failover exercises.
