Fortinet NSE6_FSW-7.2 Practice Questions

C.   FortiGate automatically saves the existing FortiSwitch configuration during the FortiLink management process.

Explanation:

When transitioning the management of a FortiSwitch from standalone mode to being managed by FortiGate via FortiLink, it is critical to ensure that the existing configurations are preserved. The best practice involves: FortiGate's Role in Configuration Preservation:FortiGate has the capability to automatically preserve the existing configuration of a FortiSwitch when it is integrated into the network via FortiLink. This feature helps ensure that the transition does not disrupt the network's operational settings.

Configuration Integration:As FortiSwitch is integrated into FortiGate's management via FortiLink, FortiGate captures and integrates the existing switch configuration, enabling a seamless transition. This process involves FortiGate recognizing the FortiSwitch and its current setup, then incorporating these settings into the centralized management interface without the need for manual reconfiguration or the use of additional tools.

B.   Enable the Forti-link setting on FortiSwitch before the authorization process

Explanation:

To switch the management mode of a FortiSwitch from standalone to FortiLink without losing the existing configuration, the best practice is: Enable the Forti-Link setting on FortiSwitch before the authorization process (Option B): This action ensures that the FortiSwitch is prepared to integrate into the FortiGate’s network without resetting its configuration. By enabling FortiLink beforehand, the switch can communicate and synchronize with the FortiGate while retaining its current settings.
References:

Fortinet’s documentation often highlights the importance of correctly configuring both FortiGate and FortiSwitch to ensure seamless integration without data loss. This procedure usually involves setting the appropriate management interface settings on the FortiSwitch to anticipate the FortiLink mode.

A.   FortiSwitch does not retain its time after a reboot, which gets reset after each reboot.

C.   FortiSwitch cannot complete the DTLS handshake used in the CAPWAP tunnel.

Explanation:

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.

D.   FortiSwitch checks ACL policies only from top to bottom.

Explanation:

In FortiSwitch, Access Control Lists (ACLs) are used to enforce security rules on both ingress and egress traffic:

ACL Evaluation Order (D):
Operational Function: FortiSwitch processes ACL entries from top to bottom, similar to how firewall rules are processed. The first match in the ACL determines the action taken on the packet, whether to allow or deny it, making the order of rules critical.

Configuration Advice: Careful planning of the order of ACL rules is necessary to ensure that more specific rules precede more general ones to avoid unintentional access or blocks.

A.   FortiGate multi-tenancy

Explanation:

FortiGate's multi-tenancy feature, specifically Virtual Domains (VDOMs), is the most appropriate tool for segmenting network operations and the administration of managed FortiSwitch devices on FortiGate. Here's why:

VDOMs as Virtual Firewalls:VDOMs function as independent virtual firewalls within a single FortiGate device. Each VDOM can have its own:

• Security policies
• Interfaces (Including FortiLink interfaces for FortiSwitch management)
• Routing table
• Administrative access

Segmenting Network Operations: By assigning different FortiSwitch devices (or groups of ports) to separate VDOMs, you effectively partition your network. Network administrators can manage specific FortiSwitches through their assigned VDOMs, maintaining operational isolation.

Enhanced Administration: VDOMs offer granular administrative control. Different administrators can be assigned to specific VDOMs, limiting their management scope and reducing the risk of accidental configuration changes.

Why Other Options Are Less Suitable:

B. Multi-chassis link aggregation trunk: This focuses on link redundancy and bandwidth aggregation, not network segmentation.
C. FortiGate clustering protocol: This is aimed at high availability and scalability of the firewall functions themselves, not the management of switches.
D. FortiLink split interface: This allows dividing a FortiLink interface on the FortiGate for managing multiple FortiSwitches, but it doesn't provide the true segmentation and administrative isolation that VDOMs offer.

B.   FortiSwitch and FortiGate devices configured with VXLAN interfaces.

D.   FortiSwitch devices that have the required internal hardware for this configuration.

Explanation:

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. References:

A.   Active multicast receiver entries are aging on each IGMP query sent on the VLAN

Explanation:

Active multicast receiver entries are aging on each IGMP query sent on the VLAN (A): When IGMP snooping querier is enabled on a VLAN, it functions to manage multicast traffic within the VLAN by keeping track of multicast group memberships. The IGMP querier sends queries to determine which ports require the multicast traffic. The multicast receiver entries, which are entries that indicate which devices have requested the multicast data, age or time out based on these IGMP queries. Each query refreshes active connections but ages out entries that no longer respond, helping to ensure that multicast traffic is only sent to ports with active receivers.
