Fortinet NSE 7 - Network Security 7.2 Support Engineer 認定 NSE7_NST-7.2 試験問題 (Q19-Q24):

質問 # 19
Which three common FortiGate-to-collector-agent connectivity issues can you identifyusing the FSSO real-time debug?(Choose three.)

A. Log is full on the collector agent.

B. Refused connection. Potential mismatch of TCP port.

C. Incompatible collector agent software version.

D. Inability to reach IP address of the collector agent.

E. Mismatched pre-shared password.

正解：B、D、E

解説：
* Refused Connection:A refused connection typically indicates a mismatch in the TCP port configuration between the FortiGate and the collector agent. Ensuring both are configured to use the same TCP port is crucial for proper connectivity.
* Mismatched Pre-Shared Password:If the pre-shared password configured on the FortiGate does not match the one set on the collector agent, authentication will fail, leading to connectivity issues.
* Inability to Reach IP Address:This can occur due to network issues such as incorrect routing, firewall rules blocking traffic, or the collector agent being down. Verifying network connectivity and the status of the collector agent is necessary to resolve this issue.

質問 # 20
Refer to the exhibit, which shows the output of get router info ospf neighbor.

What can you conclude from the command output?

A. All neighbors are in area 0.0.0.0.

B. The local FortiGate is the BDR.

C. The local FortiGate Is not a DROther.

D. The network type connectingthe local Fortigate and OSPF neighbor 0.0.0.10 is point-to-point.

正解：C

解説：
* Understanding OSPF Roles:
* In OSPF (Open Shortest Path First), routers can have different roles: Designated Router (DR), Backup Designated Router (BDR), and DROther. These roles help manage and optimize the OSPF network traffic.
* DR and BDR are elected to minimize the number of adjacencies and reduce the amount of routing information exchange.
* DROther routers are neither DR nor BDR but can still participate in the OSPF network by maintaining adjacencies with DR and BDR.
* Analyzing the Exhibit:
* The exhibit shows the OSPF neighbor states for the local FortiGate.
* Neighbor ID 0.0.0.1 is in the state Full/DR (Designated Router).
* Neighbor ID 0.0.0.3 is in the state Full/DROther (DROther).
* Neighbor ID 0.0.0.10 has no specific designation, implying it is neither DR nor BDR.
* Conclusion:
* Since the local FortiGate shows neighbors in Full/DR and Full/DROther states and itself does not have a state of DROther, it can be concluded that the local FortiGate is not a DROther.

質問 # 21
Exhibit.

Refer to the exhibit, which shows the output of diagnose syssessionlist.
If the HA ID for the primary device is0. what happens if the primary failsand the secondary becomes the primary?

A. Traffic for this session continues to be permitted on the new primary device after failover. without requiring the client to restart the session with the server.

B. The secondary device has this session synchronized; however, because application control is applied, the session is marked dirty and has to be re-evaluated after failover.

C. The session state is preserved but the kernel will need to re-evaluate the session because NAT was applied.

D. The session will be removed from the session table of the secondary device because of the presence of allowed errorpackets, which will force the client to restart the session with the server.

正解：A

解説：
* Session Synchronization:
* FortiGate HA (High Availability) ensures that active sessions are synchronized between the primary and secondary devices. This synchronization allows for seamless failover and continuity of sessions.
* Handling NAT Sessions:
* The session in the exhibit has NAT applied, as indicated by thehook=post dir=org act=snatentry.
FortiGate's HA setup is designed to handle such sessions, ensuring that traffic continues without interruption during failover.
* Session Preservation:
* Even with the presence of NAT, the session state is preserved across the HA devices. This means that ongoing sessions do not require re-establishment by the client, thus providing a seamless experience.

質問 # 22
Refer to the exhibit. whichcontains the output of diagnose vpn tunnellist.

Which command will capture ESP traffic for the VPN named DialUp_0?

A. diagnose sniffer packet any 'port 4500'

B. diagnose sniffer packet any 'esp and host 10*200.3.2'

C. diagnose sniffer packet any 'host10.0.10.10'

D. diagnose sniffer packet any 'ip proto 50'

正解：B

解説：
* Capturing ESP Traffic:
* ESP (Encapsulating Security Payload) traffic is associated with IPsec and is identified by the protocol number 50. To capture ESP traffic, you need to filter packets based on this protocol.
* In this specific case, you also need to filter for the host associated with the VPN tunnel, which is
10.200.3.2as indicated in the exhibit.
* Sniffer Command:
* The correct command to capture ESP traffic for the VPN namedDialUp_0is:
diagnose sniffer packet any 'espandhost10.200.3.2'
* This command ensures that only ESP packets to and from the specified host are captured, providing a focused and relevant data set for troubleshooting.

質問 # 23
Exhibit.

Refer to the exhibit, which contains partial output from an IKE real-time debug.
The administrator does not have access to the remote gateway.
Based on the debug output, which configuration change can the administrator make to the local gateway to resolve the phase 1 negotiation error?

A. In the phase 1 network configuration, set the IKE version to 2.

B. In the phase 1 proposal configuration, add AES256-SHA256 to the list of encryption algorithms.

C. In the phase 1 proposal configuration, add AES128-SHA128 to the list of encryption algorithms.

D. In the phase 1 proposal configuration, add AESCBC-SHA2 to the list of encryption algorithms.

正解：B

解説：
* Analyzing Debug Output:
* The debug output shows multiple proposals with encryption algorithms likeAES CBCand hashing algorithms likeSHA256.
* The negotiation failure (no SA proposal chosen) suggests that there is a mismatch in the encryption or hashing algorithms between the local and remote gateways.
* Configuration Change:
* To resolve the phase 1 negotiation error, the local gateway needs to include a compatible proposal.
* AddingAES256-SHA256to the phase 1 proposal configuration ensures that both gateways have a matching set of encryption and hashing algorithms.
