Question 710

A FortiOS 7.6 team examines: An engineer copies old peer selectors after a renumbering and the protected paths stop matching. Select TWO complementary choices: the most appropriate corrective action AND the specific evidence confirming success.

  1. Match approved IPsec phase-two traffic selectors and supported encryption proposals to the intended protected local and remote subnets.
  2. The intended child security association forms and bidirectional traffic between the approved networks succeeds.
  3. Create least-privilege firewall rules for approved IPsec source and destination networks and avoid unintended source NAT across the protected path.
  4. Treating all IPsec connectivity faults as cryptographic problems can cause unnecessary key or proposal changes.
  5. A controlled HA/WAN failover re-establishes encrypted connectivity and application flows through approved paths.

Explanation

Correct Answers

A:

The reported FortiOS 7.6 condition is: An engineer copies old peer selectors after a renumbering and the protected paths stop matching. The targeted administrative response is: Match approved IPsec phase-two traffic selectors and supported encryption proposals to the intended protected local and remote subnets. The relevant failure risk is: Mismatched traffic selectors can leave phase one healthy while the protected application subnet remains unreachable. Validate with: The intended child security association forms and bidirectional traffic between the approved networks succeeds.

B:

For the observed situation (An engineer copies old peer selectors after a renumbering and the protected paths stop matching), the most specific acceptance evidence is: The intended child security association forms and bidirectional traffic between the approved networks succeeds. It validates the recommended response: Match approved IPsec phase-two traffic selectors and supported encryption proposals to the intended protected local and remote subnets. This addresses the documented risk: Mismatched traffic selectors can leave phase one healthy while the protected application subnet remains unreachable.

Incorrect Answers

C:

VPN firewall policies and source nat exemptions (5.1) addresses another technical failure: Translating local private addresses unexpectedly may cause remote VPN selectors or application allowlists to reject traffic. This case instead tests IPsec phase-two traffic selector agreement; the choice measures or changes another part of the system.

D:

IPsec tunnel logging and diagnosis (5.1) would demonstrate or implement: Treating all IPsec connectivity faults as cryptographic problems can cause unnecessary key or proposal changes. The required paired action and test concerns IPsec phase-two traffic selector agreement; a passing result for this alternative could leave that requirement unresolved.

E:

IPsec peer and routing recovery after failover (5.1) would demonstrate or implement: A controlled HA/WAN failover re-establishes encrypted connectivity and application flows through approved paths. The paired-answer requirement concerns IPsec phase-two traffic selector agreement; this alternative does not provide the matching intervention and separate acceptance evidence.

Question 711

A FortiGate administrator investigates: An IPsec tunnel shows established but the route to an on-premises database still targets the internet gateway. Which response most directly addresses the described technical requirement?

  1. Validate phase-one, phase-two, tunnel-route and application policy recovery following an authorized FortiGate HA or WAN failover.
  2. Use FortiGate VPN event logs and approved bounded diagnostic data to distinguish IKE, phase-two, routing and firewall policy failures.
  3. Use supported route-based IPsec tunnel interfaces with appropriate routing and firewall policy for protected application subnets.
  4. Check effective VPN path MTU and approved TCP MSS handling when protected application traffic fails on larger packets.

Explanation

Correct Answer

C:

The reported FortiOS 7.6 condition is: An IPsec tunnel shows established but the route to an on-premises database still targets the internet gateway. The targeted administrative response is: Use supported route-based IPsec tunnel interfaces with appropriate routing and firewall policy for protected application subnets. The relevant failure risk is: A valid tunnel negotiation alone does not install the necessary destination route or permit application traffic. Validate with: Route lookup, tunnel counters and narrow firewall policies confirm authorized packets cross the correct VPN interface.

Incorrect Answers

A:

IPsec peer and routing recovery after failover (5.1) addresses another technical failure: A healthy replacement firewall can be active while tunnel security associations, NAT or route state have not recovered. The case states: An IPsec tunnel shows established but the route to an on-premises database still targets the internet gateway. The most direct diagnosis is: Use supported route-based IPsec tunnel interfaces with appropriate routing and firewall policy for protected application subnets.

B:

IPsec tunnel logging and diagnosis (5.1) addresses another technical failure: Treating all IPsec connectivity faults as cryptographic problems can cause unnecessary key or proposal changes. This choice can be useful for that problem, but it does not establish the Route-based IPsec tunnel interface design control being assessed here.

D:

IPsec tunnel mtu and fragmentation (5.1) addresses another technical failure: IPsec encapsulation overhead can make large packets fail even while small ICMP connectivity tests succeed. The required diagnosis concerns Route-based IPsec tunnel interface design; a passing result for this alternative could leave that requirement unresolved.

Question 712

Following an approved configuration change, the team observes: An IPsec tunnel shows established but the route to an on-premises database still targets the internet gateway. Which result would most convincingly demonstrate that the intended correction worked?

  1. Protected hosts see approved original source networks and tests show firewall permits only the required services.
  2. Route lookup, tunnel counters and narrow firewall policies confirm authorized packets cross the correct VPN interface.
  3. A monitored tunnel remains usable through planned rekey with approved proposals and no unexpected loss of reachability.
  4. Both intended IKE peers report an established phase-one security association with approved algorithms and correct identities.

Explanation

Correct Answer

B:

For the observed situation (An IPsec tunnel shows established but the route to an on-premises database still targets the internet gateway), the most specific acceptance evidence is: Route lookup, tunnel counters and narrow firewall policies confirm authorized packets cross the correct VPN interface. It validates the recommended response: Use supported route-based IPsec tunnel interfaces with appropriate routing and firewall policy for protected application subnets. This addresses the documented risk: A valid tunnel negotiation alone does not install the necessary destination route or permit application traffic.

Incorrect Answers

A:

VPN firewall policies and source nat exemptions (5.1) would demonstrate or implement: Protected hosts see approved original source networks and tests show firewall permits only the required services. The case states: An IPsec tunnel shows established but the route to an on-premises database still targets the internet gateway. The most direct evidence is: Route lookup, tunnel counters and narrow firewall policies confirm authorized packets cross the correct VPN interface.

C:

VPN encryption rekey and lifetime compatibility (5.1) would demonstrate or implement: A monitored tunnel remains usable through planned rekey with approved proposals and no unexpected loss of reachability. This case instead tests Route-based IPsec tunnel interface design; the choice measures or changes another part of the system.

D:

IPsec phase-one ike identity and proposals (5.1) would demonstrate or implement: Both intended IKE peers report an established phase-one security association with approved algorithms and correct identities. The required evidence concerns Route-based IPsec tunnel interface design; a passing result for this alternative could leave that requirement unresolved.

Question 713

During a controlled branch network review, engineers find: A branch site adds a remote network but has no corresponding tunnel-interface policy. Which response most directly addresses the described technical requirement?

  1. Align compatible supported IKE and IPsec SA lifetime and rekey behavior across approved VPN peers and monitor rekey outcomes.
  2. Validate approved IPsec phase-one IKE peer identity, authentication credentials and mutually supported cryptographic proposals on both FortiGate ends.
  3. Use supported route-based IPsec tunnel interfaces with appropriate routing and firewall policy for protected application subnets.
  4. Create least-privilege firewall rules for approved IPsec source and destination networks and avoid unintended source NAT across the protected path.

Explanation

Correct Answer

C:

The reported FortiOS 7.6 condition is: A branch site adds a remote network but has no corresponding tunnel-interface policy. The targeted administrative response is: Use supported route-based IPsec tunnel interfaces with appropriate routing and firewall policy for protected application subnets. The relevant failure risk is: A valid tunnel negotiation alone does not install the necessary destination route or permit application traffic. Validate with: Route lookup, tunnel counters and narrow firewall policies confirm authorized packets cross the correct VPN interface.

Incorrect Answers

A:

VPN encryption rekey and lifetime compatibility (5.1) addresses another technical failure: Mismatched peer behavior during SA renewal can create periodic outages even when initial tunnel establishment succeeds. The case states: A branch site adds a remote network but has no corresponding tunnel-interface policy. The most direct corrective action is: Use supported route-based IPsec tunnel interfaces with appropriate routing and firewall policy for protected application subnets.

B:

IPsec phase-one ike identity and proposals (5.1) addresses another technical failure: Peer identity or proposal mismatch can prevent tunnel negotiation even when the internet path and gateway IP are reachable. This choice can be useful for that problem, but it does not establish the Route-based IPsec tunnel interface design control being assessed here.

D:

VPN firewall policies and source nat exemptions (5.1) addresses another technical failure: Translating local private addresses unexpectedly may cause remote VPN selectors or application allowlists to reject traffic. The required corrective action concerns Route-based IPsec tunnel interface design; a passing result for this alternative could leave that requirement unresolved.

Question 714

A FortiGate review documents: A branch site adds a remote network but has no corresponding tunnel-interface policy. Which failure risk is most closely associated with this concern?

  1. A valid tunnel negotiation alone does not install the necessary destination route or permit application traffic.
  2. Large traffic reordering or stale security association state can cause legitimate encrypted packets to be discarded.
  3. Two configured tunnels do not guarantee recovery if both depend on the same WAN circuit or backup routes are missing.
  4. Mismatched traffic selectors can leave phase one healthy while the protected application subnet remains unreachable.

Explanation

Correct Answer

A:

The operational condition (A branch site adds a remote network but has no corresponding tunnel-interface policy) exposes: A valid tunnel negotiation alone does not install the necessary destination route or permit application traffic. The appropriate FortiGate correction is: Use supported route-based IPsec tunnel interfaces with appropriate routing and firewall policy for protected application subnets. Its direct acceptance evidence is: Route lookup, tunnel counters and narrow firewall policies confirm authorized packets cross the correct VPN interface.

Incorrect Answers

B:

IPsec anti-replay and time-drift troubleshooting (5.1) would demonstrate or implement: Large traffic reordering or stale security association state can cause legitimate encrypted packets to be discarded. This choice can be useful for that problem, but it does not establish the Route-based IPsec tunnel interface design control being assessed here.

C:

Redundant site-to-site IPsec peers (5.1) would demonstrate or implement: Two configured tunnels do not guarantee recovery if both depend on the same WAN circuit or backup routes are missing. This case instead tests Route-based IPsec tunnel interface design; the choice measures or changes another part of the system.

D:

IPsec phase-two traffic selector agreement (5.1) would demonstrate or implement: Mismatched traffic selectors can leave phase one healthy while the protected application subnet remains unreachable. The required risk concerns Route-based IPsec tunnel interface design; a passing result for this alternative could leave that requirement unresolved.

Question 715

An enterprise security operations ticket reports: An engineer expects phase-one negotiation to create every application route automatically. Which response most directly addresses the described technical requirement?

  1. Use supported route-based IPsec tunnel interfaces with appropriate routing and firewall policy for protected application subnets.
  2. Investigate supported IPsec replay-window events, packet ordering and peer time or state anomalies using legitimate device diagnostics.
  3. Design supported primary and alternate FortiGate IPsec tunnels and test route preference and peer availability under controlled failure.
  4. Match approved IPsec phase-two traffic selectors and supported encryption proposals to the intended protected local and remote subnets.

Explanation

Correct Answer

A:

The reported FortiOS 7.6 condition is: An engineer expects phase-one negotiation to create every application route automatically. The targeted administrative response is: Use supported route-based IPsec tunnel interfaces with appropriate routing and firewall policy for protected application subnets. The relevant failure risk is: A valid tunnel negotiation alone does not install the necessary destination route or permit application traffic.

Question 716

A secure network operations review finds: An engineer expects phase-one negotiation to create every application route automatically. Which result would most convincingly demonstrate that the intended correction worked?

  1. Controlled inter-branch tests follow only authorized hub or direct tunnel paths and stay isolated where required.
  2. Route lookup, tunnel counters and narrow firewall policies confirm authorized packets cross the correct VPN interface.
  3. Large representative authorized payloads pass over the tunnel after bounded MTU adjustments without severe retransmissions.
  4. The intended child security association forms and bidirectional traffic between the approved networks succeeds.

Explanation

Correct Answer

B:

For the observed situation (An engineer expects phase-one negotiation to create every application route automatically), the most specific acceptance evidence is: Route lookup, tunnel counters and narrow firewall policies confirm authorized packets cross the correct VPN interface. It validates the recommended response: Use supported route-based IPsec tunnel interfaces with appropriate routing and firewall policy for protected application subnets. This addresses the documented risk: A valid tunnel negotiation alone does not install the necessary destination route or permit application traffic.

Incorrect Answers

A:

VPN hub-and-spoke versus partial mesh topology (5.1) would demonstrate or implement: Controlled inter-branch tests follow only authorized hub or direct tunnel paths and stay isolated where required. The case states: An engineer expects phase-one negotiation to create every application route automatically. The most direct evidence is: Route lookup, tunnel counters and narrow firewall policies confirm authorized packets cross the correct VPN interface.

Question 717

A FortiOS 7.6 deployment change reveals: A route points into the encrypted tunnel but return traffic is denied by its opposite-direction policy. Which response most directly addresses the described technical requirement?

  1. Use supported route-based IPsec tunnel interfaces with appropriate routing and firewall policy for protected application subnets.
  2. Match approved IPsec phase-two traffic selectors and supported encryption proposals to the intended protected local and remote subnets.
  3. Check effective VPN path MTU and approved TCP MSS handling when protected application traffic fails on larger packets.
  4. Choose a documented hub-and-spoke or partial-mesh IPsec topology according to required spoke-to-spoke access, redundancy and administration scale.

Explanation

Correct Answer

A:

The reported FortiOS 7.6 condition is: A route points into the encrypted tunnel but return traffic is denied by its opposite-direction policy. The targeted administrative response is: Use supported route-based IPsec tunnel interfaces with appropriate routing and firewall policy for protected application subnets. The relevant failure risk is: A valid tunnel negotiation alone does not install the necessary destination route or permit application traffic.

This case instead tests Route-based IPsec tunnel interface design; the choice measures or changes another part of the system.

D:

VPN hub-and-spoke versus partial mesh topology (5.1) addresses another technical failure: Assuming spoke-to-spoke reachability in a pure hub model without appropriate routes and policies can blackhole traffic. The required corrective action concerns Route-based IPsec tunnel interface design; a passing result for this alternative could leave that requirement unresolved.

Question 718

During a documented incident investigation, staff report: A route points into the encrypted tunnel but return traffic is denied by its opposite-direction policy. Which failure risk is most closely associated with this concern?

  1. A valid tunnel negotiation alone does not install the necessary destination route or permit application traffic.
