Question 480

A maintenance team replaces the secondary FortiGate with a unit on a different firmware build and assumes its policies will synchronize without checking compatibility. Which diagnostic evidence should the FortiGate administrator check FIRST?

  1. Inspect FortiAnalyzer registration and authorization, connectivity, device identity, log forwarding state, log types, policy logging settings and timestamps.
  2. Inspect HA group name and password, heartbeat link status, cluster member health, firmware/build compatibility, priority settings and synchronization checksums.
  3. Inspect reserved management configuration, independent management routes, peer access, HA firmware upgrade status, pre/post checksums and cluster election events.
  4. Inspect user group mapping, SSO state, endpoint registration, FortiClient agent status, posture checks, FortiSASE portal permissions and applied access policy.

Explanation

Correct Answer

B:

Inspect HA group name and password, heartbeat link status, cluster member health, firmware/build compatibility, priority settings and synchronization checksums. This distinguishes the relevant FortiGate device, session or controller evidence. FGCP heartbeat must operate over suitable dedicated links; two matching hostnames alone cannot build a synchronized HA pair or guarantee traffic survival. The corresponding action is: Configure compatible FortiGate peers as an FGCP high-availability cluster with appropriate heartbeat interfaces, group identity, matching licenses and tracked interfaces. Scenario: A maintenance team replaces the secondary FortiGate with a unit on a different firmware build and assumes its policies will synchronize without checking compatibility.

Incorrect Answers

A:

Inspect FortiAnalyzer registration and authorization, connectivity, device identity, log forwarding state, log types, policy logging settings and timestamps. This diagnostic is related to FortiAnalyzer registration and centralized log forwarding rather than the controlling evidence for this scenario. Examine instead: Inspect HA group name and password, heartbeat link status, cluster member health, firmware/build compatibility, priority settings and synchronization checksums. Scenario: A maintenance team replaces the secondary FortiGate with a unit on a different firmware build and assumes its policies will synchronize without checking compatibility.

C:

Inspect reserved management configuration, independent management routes, peer access, HA firmware upgrade status, pre/post checksums and cluster election events. This diagnostic is related to Reserved HA management, monitoring and firmware upgrades rather than the controlling evidence for this scenario. Examine instead: Inspect HA group name and password, heartbeat link status, cluster member health, firmware/build compatibility, priority settings and synchronization checksums. Scenario: A maintenance team replaces the secondary FortiGate with a unit on a different firmware build and assumes its policies will synchronize without checking compatibility.

D:

Inspect user group mapping, SSO state, endpoint registration, FortiClient agent status, posture checks, FortiSASE portal permissions and applied access policy. This diagnostic is related to FortiSASE endpoint onboarding and identity-bound access rather than the controlling evidence for this scenario. Examine instead: Inspect HA group name and password, heartbeat link status, cluster member health, firmware/build compatibility, priority settings and synchronization checksums. Scenario: A maintenance team replaces the secondary FortiGate with a unit on a different firmware build and assumes its policies will synchronize without checking compatibility.

Question 481

A VoIP quality incident persists even after the FortiGate GUI shows all uplinks green, requiring SLA-specific jitter and session steering diagnostics. Which TWO complementary choices provide the appropriate response AND the key evidence for verifying it? Select TWO.

  1. Coordinate FortiGate firewall policies and SD-WAN zones with route or application-based service steering so chosen WAN members are compatible with the intended security and NAT policy.
  2. Inspect monitor target, probe protocol, gateway link state, route suppression, recovery thresholds, event log and controlled failover timings.
  3. Traffic exits the intended interface through a reachable next hop and return connectivity works without a broader unapproved default route.
  4. Investigate FortiOS SD-WAN anomalies through rule match, health-check statistics, session tables and routing diagnostics before changing priorities or disabling monitoring.
  5. Inspect SD-WAN service status, health-check latency/loss, member availability, session selected interface, forward route, transport packet trace and logs.

Explanation

Correct Answers

D:

Investigate FortiOS SD-WAN anomalies through rule match, health-check statistics, session tables and routing diagnostics before changing priorities or disabling monitoring. This directly addresses the FortiOS configuration or response required by the case. One successful ping to a monitoring host cannot establish all application paths are healthy, and unnecessary route changes can mask the original packet-loss cause. Verify with: Inspect SD-WAN service status, health-check latency/loss, member availability, session selected interface, forward route, transport packet trace and logs. This is the implementation portion of the required complementary pair. Scenario: A VoIP quality incident persists even after the FortiGate GUI shows all uplinks green, requiring SLA-specific jitter and session steering diagnostics.

E:

Inspect SD-WAN service status, health-check latency/loss, member availability, session selected interface, forward route, transport packet trace and logs. This distinguishes the relevant FortiGate device, session or controller evidence. One successful ping to a monitoring host cannot establish all application paths are healthy, and unnecessary route changes can mask the original packet-loss cause. The corresponding action is: Investigate FortiOS SD-WAN anomalies through rule match, health-check statistics, session tables and routing diagnostics before changing priorities or disabling monitoring. This is the verification portion of the required complementary pair. Scenario: A VoIP quality incident persists even after the FortiGate GUI shows all uplinks green, requiring SLA-specific jitter and session steering diagnostics.

Incorrect Answers

A:

Coordinate FortiGate firewall policies and SD-WAN zones with route or application-based service steering so chosen WAN members are compatible with the intended security and NAT policy. This choice relates to SD-WAN interactions with firewall policies and source-specific routes, not the complementary implementation-and-evidence pair for the case. Implement: Investigate FortiOS SD-WAN anomalies through rule match, health-check statistics, session tables and routing diagnostics before changing priorities or disabling monitoring. Check: Inspect SD-WAN service status, health-check latency/loss, member availability, session selected interface, forward route, transport packet trace and logs. Scenario: A VoIP quality incident persists even after the FortiGate GUI shows all uplinks green, requiring SLA-specific jitter and session steering diagnostics.

B:

Inspect monitor target, probe protocol, gateway link state, route suppression, recovery thresholds, event log and controlled failover timings. This choice relates to Link monitoring and static route failover triggers, not the complementary implementation-and-evidence pair for the case. Implement: Investigate FortiOS SD-WAN anomalies through rule match, health-check statistics, session tables and routing diagnostics before changing priorities or disabling monitoring. Check: Inspect SD-WAN service status, health-check latency/loss, member availability, session selected interface, forward route, transport packet trace and logs. Scenario: A VoIP quality incident persists even after the FortiGate GUI shows all uplinks green, requiring SLA-specific jitter and session steering diagnostics.

C:

Traffic exits the intended interface through a reachable next hop and return connectivity works without a broader unapproved default route. This choice relates to FortiGate static default routes and interface reachability, not the complementary implementation-and-evidence pair for the case. Implement: Investigate FortiOS SD-WAN anomalies through rule match, health-check statistics, session tables and routing diagnostics before changing priorities or disabling monitoring. Check: Inspect SD-WAN service status, health-check latency/loss, member availability, session selected interface, forward route, transport packet trace and logs. Scenario: A VoIP quality incident persists even after the FortiGate GUI shows all uplinks green, requiring SLA-specific jitter and session steering diagnostics.

Question 482

A site publishes two services with overlapping VIP external ports, and intermittent access requires inspecting actual VIP selection rather than changing unrelated client DNS settings. Which observable result BEST demonstrates that the intended FortiGate security or connectivity requirement is satisfied?

  1. Internal clients resolve and reach the intended server consistently without bypassing stateful inspection or exposing additional services.
  2. A reproducible user authentication event produces the expected group entry and protected session, while stale entries are cleared without broadening firewall rules.
  3. Only intended flows match the narrow allow rule while unauthorized traffic remains denied with sufficient diagnostics.
  4. A test flow shows symmetric forward and return tuples, correct NAT mappings and stable application transactions through the intended policy.

Explanation

Correct Answer

D:

A test flow shows symmetric forward and return tuples, correct NAT mappings and stable application transactions through the intended policy. This is the operational validation outcome rather than merely an enabled setting. 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. Scenario: A site publishes two services with overlapping VIP external ports, and intermittent access requires inspecting actual VIP selection rather than changing unrelated client DNS settings.

Incorrect Answers

A:

Internal clients resolve and reach the intended server consistently without bypassing stateful inspection or exposing additional services. This result would test NAT hairpin and internal use of public VIP names but does not demonstrate the desired FortiGate outcome here. Verify instead: A test flow shows symmetric forward and return tuples, correct NAT mappings and stable application transactions through the intended policy. Scenario: A site publishes two services with overlapping VIP external ports, and intermittent access requires inspecting actual VIP selection rather than changing unrelated client DNS settings.

B:

A reproducible user authentication event produces the expected group entry and protected session, while stale entries are cleared without broadening firewall rules. This result would test FSSO troubleshooting and authentication connector health but does not demonstrate the desired FortiGate outcome here. Verify instead: A test flow shows symmetric forward and return tuples, correct NAT mappings and stable application transactions through the intended policy. Scenario: A site publishes two services with overlapping VIP external ports, and intermittent access requires inspecting actual VIP selection rather than changing unrelated client DNS settings.

C:

Only intended flows match the narrow allow rule while unauthorized traffic remains denied with sufficient diagnostics. This result would test Firewall policy evaluation order, interfaces and least privilege but does not demonstrate the desired FortiGate outcome here. Verify instead: A test flow shows symmetric forward and return tuples, correct NAT mappings and stable application transactions through the intended policy. Scenario: A site publishes two services with overlapping VIP external ports, and intermittent access requires inspecting actual VIP selection rather than changing unrelated client DNS settings.

Question 483

A traffic spike fills the configured local log disk and the appliance begins overwriting records earlier than its retention target. Which diagnostic evidence should the FortiGate administrator check FIRST?

  1. Examine diagnose sys top or equivalent supported process views, CPU load by core, session throughput, UTM process consumption, interrupts and incident timestamps.
  2. Inspect FortiAnalyzer registration and authorization, connectivity, device identity, log forwarding state, log types, policy logging settings and timestamps.
  3. Compare hardware log-storage availability, logging destination configuration, severity filters, disk usage, log-rate statistics and remote collector acknowledgments.
  4. Correlate policy ID, source/destination interfaces, session action, NAT translation, security profile result, user identity, time range and log destination.

Explanation

Correct Answer

C:

Compare hardware log-storage availability, logging destination configuration, severity filters, disk usage, log-rate statistics and remote collector acknowledgments. This distinguishes the relevant FortiGate device, session or controller evidence. Some FortiGate models have no local log disk; memory-resident events are not durable archival storage, and choosing a collector without verifying ingestion is insufficient. The corresponding action is: 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. Scenario: A traffic spike fills the configured local log disk and the appliance begins overwriting records earlier than its retention target.

Incorrect Answers

A:

Examine diagnose sys top or equivalent supported process views, CPU load by core, session throughput, UTM process consumption, interrupts and incident timestamps. This diagnostic is related to CPU process health and abnormal-load troubleshooting rather than the controlling evidence for this scenario. Examine instead: Compare hardware log-storage availability, logging destination configuration, severity filters, disk usage, log-rate statistics and remote collector acknowledgments. Scenario: A traffic spike fills the configured local log disk and the appliance begins overwriting records earlier than its retention target.

B:

Inspect FortiAnalyzer registration and authorization, connectivity, device identity, log forwarding state, log types, policy logging settings and timestamps. This diagnostic is related to FortiAnalyzer registration and centralized log forwarding rather than the controlling evidence for this scenario. Examine instead: Compare hardware log-storage availability, logging destination configuration, severity filters, disk usage, log-rate statistics and remote collector acknowledgments. Scenario: A traffic spike fills the configured local log disk and the appliance begins overwriting records earlier than its retention target.

D:

Correlate policy ID, source/destination interfaces, session action, NAT translation, security profile result, user identity, time range and log destination. This diagnostic is related to Policy traffic log interpretation and diagnostic event filtering rather than the controlling evidence for this scenario. Examine instead: Compare hardware log-storage availability, logging destination configuration, severity filters, disk usage, log-rate statistics and remote collector acknowledgments. Scenario: A traffic spike fills the configured local log disk and the appliance begins overwriting records earlier than its retention target.

Question 484

A web-filter policy blocks newly registered domains, but one business service uses a short-lived subdomain that requires a documented risk decision rather than a global allow. Which observable result BEST demonstrates that the intended FortiGate security or connectivity requirement is satisfied?

  1. The selected IPS policy blocks intended known threats with acceptable measured latency and resource load under real peak conditions.
  2. The desired category or hostname restriction is enforced where supported and any path-based policy explicitly requires appropriate decrypting inspection.
  3. Managed endpoints validate permitted intercepted TLS sessions without certificate errors and reject untrusted or forged inspection identities.
  4. An incorrectly classified approved site receives a narrow documented exception while disallowed categories continue to be blocked for the intended groups.

Explanation

Correct Answer

D:

An incorrectly classified approved site receives a narrow documented exception while disallowed categories continue to be blocked for the intended groups. This is the operational validation outcome rather than merely an enabled setting. Category-based filtering is only as accurate as current rating data and profile ordering; an override for one domain can affect all paths hosted there. Scenario: A web-filter policy blocks newly registered domains, but one business service uses a short-lived subdomain that requires a documented risk decision rather than a global allow.

Incorrect Answers

A:

The selected IPS policy blocks intended known threats with acceptable measured latency and resource load under real peak conditions. This result would test IPS process CPU demand and inspection capacity but does not demonstrate the desired FortiGate outcome here. Verify instead: An incorrectly classified approved site receives a narrow documented exception while disallowed categories continue to be blocked for the intended groups. Scenario: A web-filter policy blocks newly registered domains, but one business service uses a short-lived subdomain that requires a documented risk decision rather than a global allow.

B:

The desired category or hostname restriction is enforced where supported and any path-based policy explicitly requires appropriate decrypting inspection. This result would test HTTPS web filtering hostname limitations and logging but does not demonstrate the desired FortiGate outcome here. Verify instead: An incorrectly classified approved site receives a narrow documented exception while disallowed categories continue to be blocked for the intended groups. Scenario: A web-filter policy blocks newly registered domains, but one business service uses a short-lived subdomain that requires a documented risk decision rather than a global allow.

C:

Managed endpoints validate permitted intercepted TLS sessions without certificate errors and reject untrusted or forged inspection identities. This result would test FortiGate deep-inspection CA trust and certificate deployment but does not demonstrate the desired FortiGate outcome here. Verify instead: An incorrectly classified approved site receives a narrow documented exception while disallowed categories continue to be blocked for the intended groups. Scenario: A web-filter policy blocks newly registered domains, but one business service uses a short-lived subdomain that requires a documented risk decision rather than a global allow.

Question 485

A new application signature begins flagging internal update traffic as anonymization software, and administrators need packet and signature context before adding an exception. Which TWO complementary choices provide the appropriate response AND the key evidence for verifying it? Select TWO.

  1. Review application log signature name, action, profile override, FortiGuard signature version, client flow, SSL inspection and change history.
  2. Approved HTTPS content receives the intended inspection depth while unsupported or privacy-sensitive traffic follows explicit reviewed exceptions.
  3. Investigate FortiOS application detection logs and signature revisions before creating narrowly scoped exclusions, ensuring legitimate traffic and policy intent remain visible.
  4. Choose monitor, pass, block or supported application control actions for specific signatures and business roles, validating whether a detected application is truly prevented from operating.
  5. Inspect application category membership, application-specific overrides, signature IDs, traffic matches, session logs and inspection visibility.

Explanation

Correct Answers

A:

Review application log signature name, action, profile override, FortiGuard signature version, client flow, SSL inspection and change history. This distinguishes the relevant FortiGate device, session or controller evidence. A single application signature hit may be insufficient to prove a user deliberately launched that program; classification and encrypted traffic can be imperfect. The corresponding action is: Investigate FortiOS application detection logs and signature revisions before creating narrowly scoped exclusions, ensuring legitimate traffic and policy intent remain visible. This is the verification portion of the required complementary pair. Scenario: A new application signature begins flagging internal update traffic as anonymization software, and administrators need packet and signature context before adding an exception.

C:

Question 486

After a laptop receives a new DHCP lease, FortiGate still maps the old address to an administrator and grants a guest machine access to a restricted VLAN. Which TWO complementary choices provide the appropriate response AND the key evidence for verifying it? Select TWO.

  1. Authorized users receive the intended group or MFA result and unauthorized or unavailable-server attempts fail according to explicit policy.
  2. Inspect user login record, workstation lease, FSSO IP mapping, authentication cache age, NAT visibility, terminal service mappings and policy match logs.
  3. Inspect object IP ranges, DNS resolution for dynamic objects, zone membership, custom service ports and protocol, schedule objects and effective policy matches.
  4. Maintain reliable FSSO user-IP associations with accurate DHCP/session changes and supported endpoint identification, limiting trust in shared or NATed source addresses.
  5. Map the intended AD security groups through FSSO collector group filters and FortiGate firewall user groups, checking nested membership and current event identity.

Explanation

Correct Answers

B:

Inspect user login record, workstation lease, FSSO IP mapping, authentication cache age, NAT visibility, terminal service mappings and policy match logs. This distinguishes the relevant FortiGate device, session or controller evidence. An IP-to-username mapping can become stale after DHCP reassignment, and many users sharing one public NAT address cannot always be distinguished by IP alone. The corresponding action is: Maintain reliable FSSO user-IP associations with accurate DHCP/session changes and supported endpoint identification, limiting trust in shared or NATed source addresses. This is the verification portion of the required complementary pair. Scenario: After a laptop receives a new DHCP lease, FortiGate still maps the old address to an administrator and grants a guest machine access to a restricted VLAN.

D:

Incorrect Answers

A:

Authorized users receive the intended group or MFA result and unauthorized or unavailable-server attempts fail according to explicit policy. This choice relates to RADIUS authentication and policy-bound MFA validation, not the complementary implementation-and-evidence pair for the case. Implement: Maintain reliable FSSO user-IP associations with accurate DHCP/session changes and supported endpoint identification, limiting trust in shared or NATed source addresses.

E:

Map the intended AD security groups through FSSO collector group filters and FortiGate firewall user groups, checking nested membership and current event identity. This choice relates to FSSO group filters and AD membership reconciliation, not the complementary implementation-and-evidence pair for the case.

Question 487

A new application signature begins flagging internal update traffic as anonymization software, and administrators need packet and signature context before adding an exception. Which diagnostic evidence should the FortiGate administrator check FIRST?

  1. Inspect SSL inspection mode, matched policy, negotiated TLS version, inspected application certificate, session log and target protocol support.
  2. Review application log signature name, action, profile override, FortiGuard signature version, client flow, SSL inspection and change history.
  3. Check inspection CA selection, certificate lifetime and chain, endpoint trust-store deployment, private-key controls, browser warnings and handshake logs.
  4. Check application signature database freshness, policy ID, inspection profile, session protocol, application detection event and decryption scope.

Explanation

Correct Answer

B:

Question 488

A home-office gateway changes its external mapped UDP port frequently, causing repeated IKE failures even though users can browse the internet normally. Which TWO complementary choices provide the appropriate response AND the key evidence for verifying it? Select TWO.

  1. Users receive policy access consistent with actual intended directory membership and changes propagate without expanding unrelated privileges.
  2. Integrate FortiGate IPsec tunnel interfaces into a supported SD-WAN steering design, ensuring underlay reachability, overlay routes and matching firewall policies for protected traffic.
  3. Compare connected PoP, endpoint tunnel state, DNS resolution, traffic steering mode, cloud security inspection result, private-app connector health and remote-user event logs.
  4. Inspect peer NAT detection, outer public addresses and ports, IKE 500/4500 flows, upstream firewall rules, mapped address stability and peer debug logs.
  5. Enable and diagnose FortiOS IPsec NAT traversal where peers sit behind compatible NAT devices, checking UDP 4500 encapsulation and public endpoint reachability.

Explanation

Correct Answers

D:

Inspect peer NAT detection, outer public addresses and ports, IKE 500/4500 flows, upstream firewall rules, mapped address stability and peer debug logs. This distinguishes the relevant FortiGate device, session or controller evidence. ESP may need UDP encapsulation through NAT, and multiple layers of translation or endpoint port restrictions can disrupt peer reachability independently of Phase 2 selectors. The corresponding action is: Enable and diagnose FortiOS IPsec NAT traversal where peers sit behind compatible NAT devices, checking UDP 4500 encapsulation and public endpoint reachability. This is the verification portion of the required complementary pair.

Question 489

An engineer moves a temporary any-any troubleshooting rule above production policy groups and unexpectedly opens multiple previously protected application ports. Which observable result BEST demonstrates that the intended FortiGate security or connectivity requirement is satisfied?

  1. Tests confirm approved users reach only intended destinations and services without unintended wildcard access after object or zone changes.
  2. Access succeeds only for the intended group during its authorized time period, while expired sessions and newly unauthorized flows behave predictably.
  3. A valid user authenticates into the correct FortiGate user group while wrong passwords and unmapped groups are denied without bypass policies.
  4. Only intended flows match the narrow allow rule while unauthorized traffic remains denied with sufficient diagnostics.

Explanation

Correct Answer

D:

Only intended flows match the narrow allow rule while unauthorized traffic remains denied with sufficient diagnostics. This is the operational validation outcome rather than merely an enabled setting. FortiGate policy order and first matching rule are crucial; creating a restrictive rule below an unrestricted matching policy does not constrain existing allowed sessions. Scenario: An engineer moves a temporary any-any troubleshooting rule above production policy groups and unexpectedly opens multiple previously protected application ports.

Incorrect Answers

A:

Tests confirm approved users reach only intended destinations and services without unintended wildcard access after object or zone changes. This result would test Address and service objects, interface zones, and policy scoping but does not demonstrate the desired FortiGate outcome here. Verify instead: Only intended flows match the narrow allow rule while unauthorized traffic remains denied with sufficient diagnostics. Scenario: An engineer moves a temporary any-any troubleshooting rule above production policy groups and unexpectedly opens multiple previously protected application ports.

B:

Access succeeds only for the intended group during its authorized time period, while expired sessions and newly unauthorized flows behave predictably. This result would test Schedule, authenticated groups and policy-specific change control but does not demonstrate the desired FortiGate outcome here. Verify instead: Only intended flows match the narrow allow rule while unauthorized traffic remains denied with sufficient diagnostics. Scenario: An engineer moves a temporary any-any troubleshooting rule above production policy groups and unexpectedly opens multiple previously protected application ports.

C:

A valid user authenticates into the correct FortiGate user group while wrong passwords and unmapped groups are denied without bypass policies. This result would test LDAP remote user integration over trusted TLS but does not demonstrate the desired FortiGate outcome here. Verify instead: Only intended flows match the narrow allow rule while unauthorized traffic remains denied with sufficient diagnostics. Scenario: An engineer moves a temporary any-any troubleshooting rule above production policy groups and unexpectedly opens multiple previously protected application ports.

Question 490

A newly built IPS sensor uses an action of monitor for critical signatures and management incorrectly assumes every detected exploit was blocked. Which observable result BEST demonstrates that the intended FortiGate security or connectivity requirement is satisfied?

  1. The selected IPS policy blocks intended known threats with acceptable measured latency and resource load under real peak conditions.
  2. Blocked DNS queries and permitted browser requests behave in accordance with distinct DNS and web policies, with no assumption that one control inspects all channels.
  3. The targeted false positive no longer interrupts an approved service, while exploit attempts retain blocking coverage and traceable alerts.
  4. A controlled benign exploit simulation triggers the expected IPS action while legitimate application transactions continue under tested exclusions.

Explanation

Correct Answer

D:

A controlled benign exploit simulation triggers the expected IPS action while legitimate application transactions continue under tested exclusions. This is the operational validation outcome rather than merely an enabled setting. 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. Scenario: A newly built IPS sensor uses an action of monitor for critical signatures and management incorrectly assumes every detected exploit was blocked.

Incorrect Answers

A:

The selected IPS policy blocks intended known threats with acceptable measured latency and resource load under real peak conditions. This result would test IPS process CPU demand and inspection capacity but does not demonstrate the desired FortiGate outcome here. Verify instead: A controlled benign exploit simulation triggers the expected IPS action while legitimate application transactions continue under tested exclusions. Scenario: A newly built IPS sensor uses an action of monitor for critical signatures and management incorrectly assumes every detected exploit was blocked.

B:

Blocked DNS queries and permitted browser requests behave in accordance with distinct DNS and web policies, with no assumption that one control inspects all channels. This result would test DNS filtering versus web filtering visibility boundaries but does not demonstrate the desired FortiGate outcome here. Verify instead: A controlled benign exploit simulation triggers the expected IPS action while legitimate application transactions continue under tested exclusions. Scenario: A newly built IPS sensor uses an action of monitor for critical signatures and management incorrectly assumes every detected exploit was blocked.

C:

The targeted false positive no longer interrupts an approved service, while exploit attempts retain blocking coverage and traceable alerts. This result would test IPS signatures, logs and focused exception maintenance but does not demonstrate the desired FortiGate outcome here. Verify instead: A controlled benign exploit simulation triggers the expected IPS action while legitimate application transactions continue under tested exclusions. Scenario: A newly built IPS sensor uses an action of monitor for critical signatures and management incorrectly assumes every detected exploit was blocked.
