Fortinet NSE6_FSW-7.2 Test Dumps

B.   Users who fail 802.1X authentication can be placed on the quarantine VLAN.

Answer DescriptionExplanation:

The correct statement about the quarantine VLAN on FortiSwitch is:

B. Users who fail 802.1X authentication can be placed on the quarantine VLAN. This feature allows network administrators to isolate devices that do not meet the network’s security criteria as determined through 802.1X authentication. Placing these devices in a quarantine VLAN restricts their network access, thereby protecting the network from potential security threats posed by unauthorized or compromised devices.

Option A is incorrect as the presence of a DHCP server in a quarantine VLAN depends on specific network configurations. Option C is incorrect without more context regarding global settings, and Option D misstates the functionality of quarantine VLANs, as their primary use is to restrict, not block, devices without additional VLAN configuration changes.

A.   QSFP+ transceiver

Answer DescriptionExplanation:

QSFP+ transceiver (A): The QSFP+ (Quad Small Form-factor Pluggable Plus) transceiver is designed to handle 40G data rates and can be used to split a 40G port into multiple 10G connections. This type of transceiver supports such configurations, making it suitable for high-density applications where multiple 10G connections are derived from a single 40G port, thereby maximizing the utilization of the port and the fiber infrastructure.

B.   FortiGate applies the quarantine-related configuration only on FortiGate.


D.   MAC address quarantine can be enabled through the FortiGate CLI only.

Answer DescriptionExplanation:

Automatic MAC address quarantine is a security feature within the FortiGate/FortiSwitch integration. Here's how it works and why the answers are correct:

The Role of FortiGate: FortiGate is the central decision point for quarantine actions. It identifies suspicious MAC addresses and communicates quarantine instructions to the FortiSwitch. The FortiSwitch doesn't make quarantine decisions on its own.

Quarantine Mechanisms: While the decision is made on FortiGate, FortiSwitch supports two ways to enforce the quarantine:

VLAN Quarantine Mode: In this mode, the FortiSwitch moves the quarantined MAC address into a dedicated quarantine VLAN. This isolates the device.exclamation

Port Quarantine Mode: The FortiSwitch disables the physical port where the quarantined MAC address is detected.

Configuration: Enabling MAC address quarantine involves configuring parameters on the FortiGate, notably via the CLI but also through the GUI depending on your FortiOS version.

Why the Other Options are Incorrect:

A. FortiSwitch supports only by VLAN quarantine mode.This is incorrect. FortiSwitch can use both VLAN-based and port-based quarantine methods.

C. FortiAnalyzer with a threat detection services license is required.FortiAnalyzer can provide deeper analysis and logging, but it's not mandatory for the core functionality of MAC address quarantine.

A.   A FortiLink interface must be enabled on FortiGate.


B.   The switch controller feature must be enabled on FortiGate.

Answer DescriptionExplanation:

A FortiLink interface must be enabled on FortiGate (A): To manage a FortiSwitch stack, a dedicated FortiLink interface on the FortiGate is required. This interface is used to manage the communication between FortiGate and the FortiSwitch stack, enabling centralized control and configuration of the switches directly from the FortiGate.

The switch controller feature must be enabled on FortiGate (B): Enabling the switch controller feature on FortiGate allows it to manage connected FortiSwitch units. This feature provides tools and interfaces on the FortiGate for overseeing FortiSwitch configurations, monitoring switch status, and managing network policies across the stack.

C.   Enable IGMP snooping proxy.

Answer DescriptionExplanation:

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.

A.   All hosts behind an authenticated port are allowed access after a successful authentica-tion.


D.   All devices connecting to FortiSwitch must support 802.1X authentication.

Answer DescriptionExplanation:

All hosts behind an authenticated port are allowed access after a successful authentication (A): Once a device on a port successfully authenticates using 802.1X, all other devices connected behind that port also gain network access. This is typical in scenarios where a switch is behind an authenticated port and not each device individually authenticates.

All devices connecting to FortiSwitch must support 802.1X authentication (D): For a network secured with 802.1X, all devices attempting to connect through the FortiSwitch must support and participate in 802.1X authentication to gain access. This ensures that all devices on the network are authenticated before they are allowed to communicate on the network.

B.   FortiGate managing FortiSwitch

Answer DescriptionExplanation:

In a hierarchical network model, the role of a device functioning simultaneously as both the distribution and core is most accurately described as "FortiGate managing FortiSwitch (B)." In this setup, FortiGate acts as the central unit managing multiple FortiSwitch units, thereby functioning both as a distribution layer—handling traffic between network segments—and as a core layer—managing traffic within the network on a broader scale. This setup is typical in medium-sized networks where a single device is capable enough to handle both roles effectively.

B.   Sniffer profile

Answer DescriptionExplanation:

FortiSwitch supports packet capture through various methods, but the Sniffer profile is specifically capable of capturing traffic on both trunks and management interfaces. Here's why:

Sniffer Profile (B):

Versatile Capture: The sniffer profile in FortiSwitch is designed to capture traffic across different types of interfaces, including trunks (where multiple VLANs are present) and management interfaces (used for controlling and monitoring the switch).

Configuration Flexibility: You can configure sniffer profiles to target specific traffic, offering flexibility in monitoring and troubleshooting network issues on both data and management planes.

Other Options:

SPAN (A) is used mainly for mirroring traffic to another port for analysis but is typically limited in its ability to capture management interface traffic.

sFlow (C) and TCP dump (D) are useful tools but do not specifically align with the capability to universally capture traffic across trunks and management interfaces in the context described.

C.   Location

Answer DescriptionExplanation:

Location (C): FortiSwitch uses LLDP-MED (Link Layer Discovery Protocol - Media Endpoint Discovery) to advertise various attributes to IP phones, among which "Location" is crucial in emergency situations. This information helps emergency responders to determine the physical location of the calling device, which is vital for prompt response in critical situations.

A.   All ports have auto-discovery enabled by default.

Answer DescriptionExplanation:

Fortinet FortiLink Protocol: The FortiLink protocol is Fortinet's proprietary mechanism for managing FortiSwitch units from a FortiGate firewall. It simplifies configuration and security policy enforcement across the connected network devices.

Auto-Discovery: FortiLink's auto-discovery feature means that by default, all ports on a FortiSwitch will actively send out discovery frames. This allows them to locate a FortiGate device that has a FortiLink interface enabled, streamlining the device management process.

No Configuration Needed: You don't have to manually configure individual ports for FortiLink discovery on FortiSwitch devices.
