Fortinet Updated NSE5_FSW_AD-7.6 Exam Questions and Answers by murphy

Time synchronization between FortiGate and its managed FortiSwitch devices is essential for several reasons:

A. FortiSwitch does not retain its time after a reboot, which gets reset after each reboot.This characteristic of FortiSwitch underlines the importance of time synchronization with FortiGate. Since FortiSwitch loses its time settings upon reboot, synchronizing with FortiGate ensures that its system clock is accurate, which is vital for logging, troubleshooting, and security timestamping.

C. FortiSwitch cannot complete the DTLS handshake used in the CAPWAP tunnel.Accurate time synchronization is crucial for security protocols such as DTLS, which rely on timestamped certificates for establishing a secure connection. If the time on FortiSwitch is not synchronized with FortiGate, the DTLS handshake used in the CAPWAP tunnel for secure communication may fail due to time discrepancies, impacting the management and operation of the switch.

To deploy FortiSwitch in a remote location with multiple VLANs and no Layer 3 switch or router, you would need specific configurations:

VXLAN Interfaces (B):

Purpose:VXLAN (Virtual Extensible LAN) allows network segmentation without a Layer 3 device, extending VLAN capabilities across dispersed geographical locations over the WAN.

Implementation:Configuring VXLAN on both FortiSwitch and FortiGate can encapsulate Layer 2 traffic over a Layer 3 network, making it ideal for scenarios lacking dedicated routing hardware.

Appropriate Hardware (D):

Requirement:Not all FortiSwitch models might support advanced features like VXLAN; hence, ensuring that the hardware can support such configurations is crucial.

According to theFortiSwitchOS 7.6 Administration Guideand theFortiSwitch 7.6 Study Guide, Quality of Service (QoS) on a FortiSwitch involves several distinct stages to manage traffic priority and bandwidth. The specific process of taking identified packets and placing them into a specific priority buffer for transmission is known asQueuing.1

On FortiSwitch, when a frame enters an ingress port, it is first classified based on its incomingCoS(Layer 2) orDSCP(Layer 3) markings.2However, it is theQueuing for egress traffic (Option B)mechanism that dictates which of the eight available hardware queues the frame will reside in before it is sent out of the destination port. The switch uses a mapping table (such as a CoS-to-queue or DSCP-to-queue map) to ensure that high-priority traffic, like voice or video, is placed in a higher-priority queue to minimize latency and jitter.

Regarding the other options:Classification (Option A)is the initial identification of the packet ' s priority but does not perform the physical mapping to a buffer.Policing (Option C)is an ingress mechanism used to drop or remark traffic that exceeds a defined rate.Shaping (Option D)is an egress mechanism that smooths out traffic bursts by delaying packets but is separate from the initial queue assignment. Therefore, the act of mapping specific markings to an egress queue is a fundamental function of the queuing mechanism.
