NSE6_FSW-7.2 - NSE6_FSW-7.2 - Fortinet NSE 6 - FortiSwitch 7.2

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.

Regarding the configuration of a FortiSwitch to split a port into multiple smaller interfaces:

• The CLI commands are enabling a split port into four 10Gbps interfaces (Option B): The command shown in the exhibit is typically used to configure a high-speed port (like a 40Gbps or 100Gbps interface) to be divided into smaller, independent 10Gbps interfaces. This feature allows more flexible use of the switch's physical resources.
• The port full speed prior to the split was 100G SFP+ (Option C): Given the context of splitting the port into multiple 10Gbps interfaces, the original port configuration likely supported a high-speed transceiver such as 100G SFP+. This would make it technically feasible to divide the interface into multiple 10Gbps channels, enhancing connectivity options without requiring additional physical interfaces.

These configurations and capabilities are typical in modern network setups, especially in environments requiring high density and flexibility in connectivity, allowing network administrators to optimize physical infrastructure efficiently.

Layer 3 routing can be configured on FortiSwitch, while managed by FortiGate (D): FortiSwitch, when managed by FortiGate, supports Layer 3 routing capabilities. This allows for routing between VLANs directly on the switch, enhancing network efficiency by reducing the need to pass traffic through higher network layers for inter-VLAN communication. This configuration enables more sophisticated network setups and efficient routing directly at the switch level.
