NSE7_LED-7.0 Practice Exam Questions with Answers Fortinet NSE 7 - LAN Edge 7.0 Certification

According to the FortiManager Administration Guide1, “FortiManager obtains the FortiSwitch status information by querying the FortiGate REST API every three minutes.” Therefore, option B is true because it describes how FortiManager gets the information about the managed switches. According to the same guide2, “If you make any changes in this module, you must install them on your managed device so that they are applied on your managed switches.” Therefore, option C is true because it describes what the administrator must do after making any changes on FortiSwitch manager. Option A is false because central management is the default management mode on FortiManager, not per-device management. Option D is false because anyswitch discovered or authorized on FortiGate will be automatically added on FortiSwitch manager, not manually.

According to the exhibit, the User-Name attribute in the RADIUS Access-Request packet contains the client MAC address of 00:0c:29:6a:2b:3d. This indicates that FortiSwitch is authenticating the client using MAC authentication bypass (MAB), which is a method of authenticating devices that do not support 802.1X by using their MAC address as the username and password. Therefore, option B is true because it explains why the User-Name attribute contains the client MAC address. Option A is false because AD machine authentication uses a computer account name and password, not a MAC address. Option C is false because user authentication uses a user name and password, not a MAC address. Option D is false because FortiSwitch is sending a RADIUS Access-Request message to FortiAuthenticator, not a RADIUS accounting message.

According to the scenario, the devices in the VLAN are connected to a FortiSwitch device that is managed by FortiGate. Quarantine is disabled on FortiGate, which means that the devices are not blocked by any security policy. The devices can ping FortiGate and FortiGate can ping the devices, which means that the IP connectivity is working. Inter-VLAN communication works, which means that the routing between VLANs is working. However, intra-VLAN communication does not work, which means that the switching within the VLAN is not working. Therefore, option C is true because the FortiSwitch MAC address table is missing entries, which means that the FortiSwitch does not know how to forward frames to the destination MAC addresses within the VLAN. Option A is false because access VLAN is enabled on the VLAN, which means that the VLAN ID is added to the frames on ingress and removed on egress. This does not affect intra-VLAN communication. Option B is false because the native VLAN configured on the ports is incorrect, which means that the frames on the native VLAN are not tagged with a VLAN ID. This does not affect intra-VLAN communication. Option D is false because the FortiGate ARP table is missing entries, which means that FortiGate does not know how to map IP addresses to MAC addresses. This does not affect intra-VLAN communication.

According to the FortiAP Configuration Guide1, “To enable the SSID, you must select at least one channel for the radio. If no channels are selected, the SSID will not be enabled. You must also enable Broadcast SSID.” Therefore, option A is true because the broadcast SSID option allows the SSID to be visible to wireless clients. Option C is also true because the SSID must be applied to an AP group that contains the APs that should be broadcasting the SSID. According to the same guide1, “You can create AP groups and assign them to different locations or departments. You can then apply different settings, such as SSIDs, to each group.” Option B is false because blocking intra-SSID traffic prevents wireless clients on the same SSID from communicating with each other, which is not related to broadcasting the SSID. Option D is false because the SSID can be applied to an AP group or a global profile, which will automatically apply to all APs, without manually configuring each AP profile.

According to the exhibit, the DHCP server scope for the FortiLink interface has a vci-string setting with the value “Cisco AP c2700”. This setting is used to match the vendor class identifier (VCI) of the DHCP clients that request an IP address from the DHCP server. The VCI is a text string that uniquely identifies a type of vendor device. Therefore, option C is true because the vci-string setting restricts the IP address assignment to FortiSwitch and FortiExtender devices, which use the VCI “Cisco AP c2700”. Option A is false because the vci-string setting does not ignore DHCP requests coming from FortiSwitch and FortiExtender devices, but rather accepts them. Option B is false because the vci-string setting does not reserve IP addresses for FortiSwitch and FortiExtender devices, but rather assigns them dynamically. Option D is false because the vci-string setting does not restrict the IP address assignment to devices that have FortiSwitch or FortiExtender as their hostname, but rather to devices that have “Cisco AP c2700” as their VCI.

According to the FortiGate CLI Reference Guide, “The diagnose test authserver ldap command tests LDAP authentication with a specific LDAP server. The command displays whether the user credentials are correct and whether the user belongs to any groups that match a firewall policy. The command also displays the LDAP codes returned by the LDAP server.” Therefore, options B and C are true because they describe the information that the diagnose test authserver ldap command can provide. Option A is false because the command does not display whether the admin bind user credentials are correct, but rather whether the user credentials are correct. Option D is false because the command does not display the LDAP groups found for the user, but rather whether the user belongs to any groups that match a firewall policy.
