Fortinet NSE6_FSW-7.2 Exam With Confidence Using Practice Dumps

The issue described pertains to the establishment of a tunnel (likely a CAPWAP tunnel for management purposes between FortiGate and FortiSwitch). Based on typical error analysis in tunnel setup scenarios:

The CAPWAP tunnel failed to come up due to a mismatch in time (Option C): This answer is plausible because time synchronization is crucial for security protocols that underpin tunnel establishments, such as DTLS (Datagram Transport Layer Security) used within CAPWAP tunnels. If the clocks on FortiGate and FortiSwitch are significantly out of sync, the security handshake (which can include timestamp validation) could fail, preventing the tunnel from coming up.

Fortinet's technical documentation typically outlines the importance of time synchronization for secure communications. In CAPWAP/DLTS scenarios, precise time matching is crucial to ensure that the cryptographic parameters align correctly during the handshake process.

To enable access to the FortiSwitch management interface from the network, certain configuration adjustments need to be made, particularly considering the VLAN settings displayed in the exhibit:

Adding port24 native VLAN to the allowed VLANs on internal (Option A): The management VLAN (VLAN 4094 in this case, as it is set as the native VLAN onthe 'internal' interface of the FortiSwitch) must be included in the allowed VLANs on the interface that provides management connectivity. Since port24 is set with a different native VLAN (VLAN 100), VLAN 4094 (the management VLAN) should be allowed through to ensure connectivity.

Allow VLAN ID 4094 on port24 if management traffic is tagged (Option C): Management traffic is tagged on VLAN 4094. Since port24 is connected to the network and serves as an uplink, allowing VLAN 4094 ensures that management traffic can reach the management interface of the FortiSwitch through this port.

The changes align with Fortinet’s best practices for setting up management VLANs and ensuring they are permitted on the relevant switch ports for proper management traffic flow.

Enable IGMP snooping proxy (C): To reduce the number of unwanted IGMP reports processed by the IGMP querier, enabling IGMP snooping proxy is effective. This feature acts as an intermediary between multicast routers and hosts, optimizing the management of IGMP messages by handling report messages locally and reducing unnecessary IGMP traffic across the network. This minimizes the processing load on the IGMP querier and improves overall network efficiency.
