質問 # 119
Refer to the exhibit, which shows the output of the command get router info bgp neighbors 100.64.2.254 advertised-routes.
What can you conclude from the output?
正解：A
質問 # 120
Refer to the exhibit, which shows partial outputs from two routing debug commands.
Which change must an administrator make on FortiGate to route web traffic from internal users to the internet, using ECMP?
正解：A
解説：
The 7.6 study guide explains the route selection order:
"Route Selection Process
Most specific route
Lowest distance
Lowest metric (dynamic routes)
Lowest priority (static routes)
ECMP (static, BGP, and OSPF routes)"**
It then states:
"If there are multiple routes with the same netmask, distance, metric, and priority, FortiGate shares the traffic among all of them. This is called equal-cost multi-path (ECMP)." The FortiOS administration guide confirms the ECMP prerequisite:
"Routes must have the same destination and costs. In the case of static routes costs include distance and priority." In the exhibit, the kernel/FIB output shows the two default routes as:
gwy=100.64.1.254 dev=3 (port1) prio=0
gwy=100.64.2.254 dev=6 (port2) prio=10
So although both are default routes, their priorities are different. Since FortiGate uses the FIB/kernel for forwarding traffic, ECMP will not happen until the static-route priorities are the same. The study guide also notes that the FIB is the table used to perform standard routing Therefore, to make the two default routes eligible for ECMP, the administrator must make the priorities equal.
Since port2 is already 10, the needed change is to set the port1 default route priority to 10.
Why the other options are wrong:
A is wrong because snat-route-change affects how existing SNAT sessions react to routing changes, not whether static routes qualify for ECMP B is wrong because changing port2 to priority 1 still would not match port1 at 0, so the routes still would not have equal cost for ECMP C is wrong because preserve-session-route affects existing-session route persistence after routing changes, not ECMP qualification
質問 # 121
Refer to the exhibit, which shows the port1 interface configuration on FortiGate and partial session information for ICMP traffic.
What happens to the session information if a routing change occurs that affects this session?
正解：D
質問 # 122
Refer to the exhibit, which shows a partial output from the get router info routing-table database command.
The administrator wants to configure a default static route for port3 and assign a distance of 50 and a priority of 0.
What will happen to the port1 and port2 default static routes after the port3 default static route is created?
正解：C
質問 # 123
Refer to the exhibit.
An IPsec VPN tunnel using IKEv2 was brought up successfully, but when the tunnel rekey takes place the tunnel goes down.
The debug command for IKE was enabled and, in the exhibit, you can review the partial output of the debug IKE while attempting to bring the tunnel up.
What is causing. The tunnel to be down?
正解：C
解説：
To determine the cause of the failure, we must analyze the IKEv2 debug output provided in the exhibit (image_ad3dc6.jpg):
Identify the Negotiation Phase:
The debug log shows: responder received CREATE_CHILD exchange.
In IKEv2, the CREATE_CHILD_SA exchange is used to create new Child SAs (Phase 2) or to rekey existing ones.
The fact that the tunnel was previously " brought up successfully " implies the initial IKE SA (Phase 1) is stable, and this error is occurring specifically during a rekey event, which often involves Perfect Forward Secrecy (PFS).
Analyze the Proposals (The Mismatch):
Incoming Proposal (Remote Peer):
The remote peer sends a proposal containing two Diffie-Hellman groups: type=DH_GROUP, val=MODP2048 (Group 14) and type=DH_GROUP, val=MODP1536 (Group 5).
My Proposal (Local FortiGate):
The local FortiGate configuration expects: type=DH_GROUP, val=MODP3072 (Group 15).
Result of the Negotiation:
The debug output concludes with: no proposal chosen and Negotiate SA Error.
This error occurs because the local FortiGate cannot find a common Diffie-Hellman group between what it requires (Group 15) and what the peer is offering (Groups 14 or 5).
While this is technically a mismatch occurring during the Phase 2 (Child SA) creation, " A Diffie-Hellman mismatch " (Option A) is the precise root cause identified in the logs.
Why other options are incorrect:
B: The log shows received create-child request, confirming that UDP traffic is reaching the device and is not blocked.
C: The failure is in the CREATE_CHILD exchange (Phase 2/Rekey), not the IKE_SA_INIT or IKE_AUTH (Phase 1) exchanges.
D: While the mismatch is occurring within the Phase 2 definitions, Option A is the specific technical reason for the no proposal chosen error shown in the DH_GROUP lines.
Reference:
FortiGate Security 7.6 Study Guide (IPsec VPN): " Phase 2 parameters... if Perfect Forward Secrecy (PFS) is enabled, a Diffie-Hellman exchange is performed again. Both peers must match the DH Group. "
