NSE7_LED-7.0 Sample Questions Answers

According to the FortiSwitch Administration Guide, “MAC-based 802.1X security mode allows you to authenticate each device connected to a port using its MAC address as the username and password.” Therefore, option B is true because it describes the MAC-based 802.1X security mode available on FortiSwitch. Option D is also true because FortiSwitch can grant different access levels to each device connected to the port based on the user group and security policy assigned to them. Option A is false because FortiSwitch does not authenticate a single device and open the port to other devices connected to the port, but rather authenticates each device individually. Option C is false because MAC-based 802.1X security mode can be used in conjunction with MAC authentication bypass (MAB) or EAP pass-through modes, which are fallback options for non-802.1X devices.

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 FortiManager Administration Guide, “Central management mode allows you to manage all FortiSwitch devices from a single interface on the FortiManager device.” Therefore, option C is true because the exhibit shows that the FortiSwitch manager is enabled and the FortiSwitch device is managed by the FortiManager device. Option D is also true because the exhibit shows that the FortiSwitch device status is offline, which means that it is not reachable by the FortiManager device, but it is authorized, which means that it has been added to the FortiManager device. Option A is false because per-device management mode allows you to manage each FortiSwitch device individually from its own web-based manager or CLI, which is not the case in the exhibit. Option B is false because the FortiSwitch device is authorized, as explained above.

According to the FortiGate Administration Guide, “EAP-TLS is the most secure EAP method. It requires a digital certificate on both the server end and the client end. The server and client authenticate each other using their certificates.” Therefore, option D is true because it describes the EAP method that requires the use of a digital certificate on both the server end and the client end. Option A is false because EAP-TTLS only requires a digital certificate on the server end, not the client end. Option B is false because PEAP also only requires a digital certificate on the server end, not the client end. Option C is false because EAP-GTC does not require a digital certificate on either the server end or the client end.

According to the exhibit, the FortiGate configuration has ocsp-status enabled and ocsp-option set to certificate. This means that FortiGate will use OCSP to verify the revocation status of certificates presented by clients. According to the FortiGate Administration Guide2, “If you select certificate, FortiGate uses an OCSP URL included in a certificate to verify that certificate.” Therefore, option C is true because it describes what action FortiGate will take when verifying the student certificate through OCSP. Option A is false because FortiGate will not reject the student certificate if the OCSP server replies that the student certificate status is unknown, but rather accept it as valid. Option B is false because FortiGate will verify the OCSPserver certificate by default, unless strict-ocsp-check is disabled. Option D is false because FortiGate will not consider the student certificate status as valid if the OCSP server is unreachable, but rather reject it as invalid.

According to the exhibit, the wireless guest users are getting a certificate error while loading the captive portal login page. This means that the browser cannot verify the identity of the server that is hosting the login page. Therefore, option A is true because the external server FQDN is incorrect, which means that it does not match the common name or subject alternative name of the server certificate. Option B is also true because the wireless user’s browser is missing a CA certificate, which means that it does not have the root or intermediate certificate that issued the server certificate. Option C is false because the FortiGate authentication interface address is using HTTPS, which is a secure protocol that encrypts the communication between the browser and the server. Option D is false because the user address is not in DDNS form, which is not related to the certificate error.

According to the FortiGate Administration Guide, “MAC address quarantine by redirect mode allows you to quarantine devices by adding their MAC addresses to a firewall address group called Quarantined Devices. The quarantined devices are kept in their current VLANs, but their traffic is redirected to a quarantine portal.” Therefore, options B and D are true because they describe the statements about MAC address quarantine by redirect mode. Option A is false because the quarantined device is not moved to the quarantine VLAN, but rather kept in the current VLAN. Option C is false because redirect mode is not the default mode for MAC address quarantine, but rather an alternative mode that can be enabled by setting mac-quarantine-mode to redirect.

According to the FortiAP Configuration Guide1, “Auto TX power control allows the AP to adjust its transmit power based on the signal strength of the client. The AP will measure the signal strength of the client every 30 seconds and adjust its transmit power up or down until the client signal is detected at -70 dBm.” Therefore, option A is true because it describes how the FortiAP wireless interface configures its transmission power when auto TX power control is enabled. Option B is false because FortiGate does not measure the signal strength of adjacent AP interfaces, but rather the FortiAP does. Option C is false because FortiGate does not adjust the adjacent AP power, but rather the FortiAP adjusts its own power. Option D is false becauseFortiGate does not measure the signal strength of the weakest associated client, but rather the FortiAP does.
