A Review Of Practical NSE7_LED-7.0 Practice

NEW QUESTION 1
Exhibit.

Refer to the exhibit showing a network topology and SSID settings.
FortiGate is configured to use an external captive portal However wireless users are not able to see the captive portal login page
Which configuration change should the administrator make to fix the problem?

• A. Enable NAT in the firewall policy with the ID 13.
• B. Add the FortiAuthenticator and WindowsAD address objects as exempt destinations services
• C. Enable the captive-portal-exempt option in the firewall policy with the ID 12
• D. Remove the guest.portal user group in the firewall policy with the ID 12

Answer: B

Explanation:
According to the exhibit, the network topology and SSID settings show that FortiGate is configured to use an external captive portal hosted on FortiAuthenticator, which is connected to a Windows AD server for user authentication. However, wireless users are not able to see the captive portal login page, which means that they are not redirected to the external captive portal URL. Therefore, option B is true because adding the FortiAuthenticator and WindowsAD address objects as exempt destinations services will allow the wireless users to access the external captive portal URL without being blocked by the firewall policy. Option A is false because enabling NAT in the firewall policy with the ID 13 will not affect the redirection to the external captive portal URL, but rather the source IP address of the wireless traffic. Option C is false because enabling the captive-portal-exempt option in the firewall policy with the ID 12will bypass the captive portal authentication for the wireless users, which is not the desired outcome. Option D is false because removing the guest.portal user group in the firewall policy with the ID 12 will prevent the wireless users from being authenticated by FortiGate, which is required for accessing the external captive portal.

NEW QUESTION 2
Which two pieces of information can the diagnose test authserver ldap command provide? (Choose two.)

• A. It displays whether the admin bind user credentials are correct
• B. It displays whether the user credentials are correct
• C. It displays the LDAP codes returned by the LDAP server
• D. It displays the LDAP groups found for the user

Answer: BC

Explanation:
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.

NEW QUESTION 3
An administrator is testing the connectivity for a new VLAN The devices in the VLAN are connected to a FortiSwitch device that is managed by FortiGate Quarantine is disabled on FortiGate
While testing the administrator noticed that devices can ping FortiGate and FortiGate can ping the devices The administrator also noticed that inter-VLAN communication works However intra-VLAN communication does not work
Which scenario is likely to cause this issue?

• A. Access VLAN is enabled on the VLAN
• B. The native VLAN configured on the ports is incorrect
• C. The FortiSwitch MAC address table is missing entries
• D. The FortiGate ARP table is missing entries

Answer: C

Explanation:
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.

NEW QUESTION 4
Refer to the exhibit.

Examine the debug output shown in the exhibit
Which two statements about the RADIUS debug output are true'' (Choose two)

• A. The user student belongs to the SSLVPN group
• B. User authentication failed
• C. The RADIUS server sent a vendor-specific attribute in the RADIUS response
• D. User authentication succeeded using MSCHAP

Answer: AD

Explanation:
According to the exhibit, the debug output shows a RADIUS debug output from FortiGate. The output shows that FortiGate sent a RADIUS Access-Request packet to FortiAuthenticator with the username student and received a RADIUS Access-Accept packet from FortiAuthenticator with a Class attribute containing SSLVPN. Therefore, option A is true because it indicates that the user student belongs to the SSLVPN group on FortiAuthenticator. The output also shows that FortiGate used MSCHAP as the authentication method and received a MS-MPPE-Send-Key and a MS-MPPE-Recv-Key from FortiAuthenticator. Therefore, option D is true because it indicates that user authentication succeeded using MSCHAP. Option B is false because user authentication did not fail, but rather succeeded. Option C is false because FortiAuthenticator did not send a vendor-specific attribute in the RADIUS response, but rather standard attributes defined by RFCs.

NEW QUESTION 5
Refer to the exhibits.

Firewall Policy

Examine the firewall policy configuration and SSID settings
An administrator has configured a guest wireless network on FortiGate using the external captive portal The administrator has verified that the external captive portal URL is correct However wireless users are not able to see the captive portal login page
Given the configuration shown in the exhibit and the SSID settings which configuration change should the administrator make to fix the problem?

• A. Disable the user group from the SSID configuration
• B. Enable the captivs-portal-exempt option in the firewall policy with the ID 11.
• C. Apply a guest.portal user group in the firewall policy with the ID 11.
• D. Include the wireless client subnet range in the Exempt Source section

Answer: C

Explanation:
According to the FortiGate Administration Guide, “To use an external captive portal, you must configure a user group that uses the external captive portal as the authentication method and apply it to a firewall policy.” Therefore, option C is true because it will allow the wireless users to be redirected to the external captive portal URL when they try to access the Internet. Option A is false because disabling the user group from the SSID configuration will prevent the wireless users from being authenticated by the FortiGate device. Option B is false because enabling the captive-portal-exempt option in the firewall policy will bypass the captive portal authentication for the wireless users, which is not the desired outcome. Option D is false because including the wireless client subnet range in the Exempt Source section will also bypass the captive portal authentication for the wireless users, which is not the desired outcome.

NEW QUESTION 6
Which two statements about MAC address quarantine by redirect mode are true? (Choose two)

• A. The quarantined device is moved to the quarantine VLAN
• B. The device MACaddress is added to the Quarantined Devices firewall address group
• C. It is the default mode for MAC address quarantine
• D. The quarantined device is kept in the current VLAN

Answer: BD

Explanation:
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.

NEW QUESTION 7
A wireless network in a school provides guest access using a captive portal to allow unregistered users to self-register and access the network The administrator is requested to update the existing configuration to provide captive portal authentication through a secure connection (HTTPS)
Which two changes must the administrator make to enforce HTTPS authentication"? (Choose two >

• A. Create a new SSID with the HTTPS captive portal URL
• B. Enable HTTP redirect in the user authentication settings
• C. Disable HTTP administrative access on the guest SSID to enforce HTTPS connection
• D. Update the captive portal URL to use HTTPS on FortiGate and FortiAuthenticator

Answer: BD

Explanation:
According to the FortiGate Administration Guide, “To enable HTTPS authentication, you must enable HTTP redirect in the user authentication settings. This redirects HTTP requests to HTTPS. You must also update the captive portal URL to use HTTPS on both FortiGate and FortiAuthenticator.” Therefore, options B and D are true because they describe the changes that the administrator must make to enforce HTTPS authentication for the captive portal. Option A is false because creating a new SSID with the HTTPS captive portal URL is not required, as the existing SSID can be updated with the new URL. Option C is false because disabling HTTP
administrative access on the guest SSID will not enforce HTTPS connection, but rather block HTTP connection.

NEW QUESTION 8
Which two statements about FortiSwitchmanager are true1? (Choose two)

• A. Per-device management is the default management mode on FortiManager
• B. FortiManager obtains the FortiSwitch status information by querying the FortiGate REST API every three minutes
• C. If the administrator makes any changes on FortiSwitch manager they must also install those changes on FortiGate so that those changes are applied on the managed switches
• D. Any switch discovered or authorized on FortiGate must be added manually on FortiSwitch manager

Answer: BC

Explanation:
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.

NEW QUESTION 9
An administrator has configured an SSID in bridge mode for corporate employees All APs are online and provisioned using default AP profiles Employees are unable to locate the SSID to conned
Which two configurations can the administrator verify? (Choose two)

• A. Verify that the broadcast SSID option is enabled in the SSID configuration
• B. Verify that the Block Intra-SSID Traffic (intra-vap-privacy) option in the SSID configuration is disabled
• C. Verify that the SSID to an AP group that should be broadcasting the SSID is applied
• D. Verify that the SSID is manually applied on AP profiles for both 2 4 GHz and 5 GHz radios

Answer: AC

Explanation:
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.

NEW QUESTION 10
Refer to the exhibit.

Examine the FortiManager configuration and FortiGate CLI output shown in the exhibit
An administrator is testing the NAC feature The test device is connected to a managed FortiSwitch device
{S224EPTF19"53€7)onpOrt2
After applying the NAC policy on port2 and generating traffic on the test device the test device is not matching the NAC policy therefore the test device remains m the onboarding VLAN
Based on the information shown in the exhibit which two scenarios are likely to cause this issue? (Choose two.)

• A. Management communication between FortiGate and FortiSwitch is down
• B. The MAC address configured on the NAC policy is incorrect
• C. The device operating system detected by FortiGate is not Linux
• D. Device detection is not enabled on VLAN 4089

Answer: AB

Explanation:
According to the FortiManager configuration, the NAC policy is set to match devices with the MAC address of 00:0c:29:6a:2b:3c and the operating system of Linux.However, according to the FortiGate CLI output, the test device has a different MAC address of 00:0c:29:6a:2b:3d. Therefore, option B is true. Option A is also true because the FortiSwitch device status is shown as down, which means that the management
communication between FortiGate and FortiSwitch is not working properly. This could prevent the NAC policy from being applied correctly. Option C is false because the device operating system detected by FortiGate is Linux, which matches the NAC policy. Option D is false because device detection is enabled on VLAN 4089, as shown by the command “config switch-controller vlan”.

NEW QUESTION 11
Refer to the exhibit.

Examine the IPsec VPN phase 1 configuration shown in the exhibit
An administrator wants to use certificate-based authentication for an IPsec VPN user
Which three configuration changes must you make on FortiGate to perform certificate-based authentication for the IPsec VPN user? (Choose three)

• A. Create a PKI user for the IPsec VPN user, and then configure the IPsec VPN tunnel to accept the PKI user as peer certificate
• B. In the Authentication section of the IPsec VPN tunnel in the Method drop-down list select Signature and then select the certificate that FortiGate will use for IPsec VPN
• C. In the IKE section of the IPsec VPN tunnel in the Mode field select Main (ID protection)
• D. Import the CA that signed the user certificate
• E. Enable XAUTH on the IPsec VPN tunnel

Answer: BDE

Explanation:
According to the FortiGate Administration Guide, “To use certificate-based authentication, you must configure the following settings on both peers: Select Signature as the authentication method and select a certificate to use for authentication. Import the CA certificate that issued the peer’s certificate. Enable XAUTH on the phase 1 configuration.” Therefore, options B, D, and E are true because they describe the configuration changes that must be made on FortiGate to perform certificate-based authentication for the IPsec VPN user. Option A is false because creating a PKI user for the IPsec VPN user is not required, as the user certificate can be verified by the CA certificate. Option C is false because changing the IKE mode to Main (ID protection) is not required, as the IKE mode can be either Main or Aggressive for certificate-based authentication.
