Fortinet NSE7_ZTA-7.2 Practice Test - Questions Answers

The FortiAnalyzer playbook configuration shown in the exhibit indicates that:

FortiAnalyzer playbooks are automated workflows that can perform actions based on triggers, conditions, and outputs. One of the actions that a playbook can perform is to quarantine a device by sending an API call to FortiClient EMS, which then instructs the FortiClient agent on the device to disconnect from the network. This can help isolate and contain a compromised or non-compliant device from spreading malware or violating policies.Reference:=

The exhibit shows the EMS Settings where various configurations related to network security are displayed. Option C is correct because, in the settings, it is indicated that HTTPS port is used (which operates over TCP) and SSL certificates are involved in securing the connection, implying the use of TLS for encryption and secure communication between FortiClient and FortiClient EMS.

Option A is incorrect because the domain that FortiClient is connecting to does not have to match the domain to which the certificate is issued. The certificate is issued by the ZTNA CA, which is a separate entity from the domain. The certificate only contains the device ID, ZTNA tags, and other information that are used to identify and authenticate the device.

Option B is incorrect because if the FortiClient EMS server certificate is invalid, FortiClient does not connect silently. Instead, it performs the Invalid Certificate Action that is configured in the settings. The Invalid Certificate Action can be set to block, warn, or allow the connection.

Option D is incorrect because default_ZTNARoot CA does not sign the FortiClient certificate for the SSL connectivity to FortiClient EMS. The FortiClient certificate is signed by the ZTNA CA, which is a different certificate authority from default_ZTNARoot CA. default_ZTNARoot CA is the EMS CA Certificate that is used to verify the identity of the EMS server.

To trigger layer 2 polling on FortiNAC, the three methods are:

A) Polling scripts: These are scripts configured within FortiNAC to actively poll the network at layer 2 to gather information about connected devices.

C) Manual polling: This involves manually initiating a polling process from the FortiNAC interface to gather current network information.

D) Scheduled tasks: Polling can be scheduled as regular tasks within FortiNAC, allowing for automated, periodic collection of network data.

The other options are not standard methods for layer 2 polling in FortiNAC:

B) Link traps: These are more related to SNMP trap messages rather than layer 2 polling.

E) Polling using API: While APIs are used for various integrations, they are not typically used for initiating layer 2 polling in FortiNAC.

Certificate-based authentication is a method of verifying the identity of a device or user by using a digital certificate issued by a trusted authority. For ZTNA deployment, certificate-based authentication is used to ensure that only authorized devices and users can access the protected applications or resources.

B) The default action for empty certificates is block. This is true because ZTNA requires both device and user verification before granting access. If a device does not have a valid certificate issued by the ZTNA CA, it will be blocked by the ZTNA gateway. This prevents unauthorized or compromised devices from accessing the network.

D) Client certificate configuration is a mandatory component for ZTNA. This is true because ZTNA relies on client certificates to identify and authenticate devices. Client certificates are generated by the ZTNA CA and contain the device ID, ZTNA tags, and other information. Client certificates are distributed to devices by the ZTNA management server (such as EMS) and are used to establish a secure connection with the ZTNA gateway.

A) FortiGate signs the client certificate submitted by FortiClient. This is false because FortiGate does not sign the client certificates. The client certificates are signed by the ZTNA CA, which is a separate entity from FortiGate. FortiGate only verifies the client certificates and performs certificate actions based on the ZTNA tags.

C) Certificate actions can be configured only on the FortiGate CLI. This is false because certificate actions can be configured on both the FortiGate GUI and CLI. Certificate actions are the actions that FortiGate takes based on the ZTNA tags in the client certificates. For example, FortiGate can allow, block, or redirect traffic based on the ZTNA tags.

FortiNAC uses a variety of methods to identify devices on the network, such as Vendor OUI, DHCP fingerprinting, and device profiling12.One of the supported communication methods that FortiNAC uses for initial device identification during discovery is SNMP (Simple Network Management Protocol)3.SNMP is a protocol that allows network devices to exchange information and monitor their status4.FortiNAC can use SNMP to read information from switches and routers, such as MAC addresses, IP addresses, VLANs, and port status3.SNMP can also be used to configure network devices and enforce policies4.Reference:1: Identification | FortiNAC 9.4.0 - Fortinet Documentation2: Device profiling process | FortiNAC 8.3.0 | Fortinet Document Library3: Using FortiNAC to identify medical devices - James Pratt4: How does FortiNAC identify a new device on the network?

LDAP (Lightweight Directory Access Protocol) authentication for ZTNA (Zero Trust Network Access) HTTPS access proxy is effectively implemented using a Form-based authentication scheme. This approach allows for a secure, interactive, and user-friendly means of capturing credentials. Form-based authentication presents a web form to the user, enabling them to enter their credentials (username and password), which are then processed for authentication against the LDAP directory. This method is widely used for web-based applications, making it a suitable choice for HTTPS access proxy setups in a ZTNA framework.

In the scenario where FortiNAC has alarm mappings configured for MDM (Mobile Device Management) compliance failure and FortiClient EMS (Endpoint Management System) is integrated as an MDM connector, the typical response when an endpoint is quarantined by FortiClient EMS is to isolate the host in the registration VLAN. This action is consistent with FortiNAC's approach to network access control, focusing on ensuring network security and compliance. By moving the non-compliant or quarantined host to a registration VLAN, FortiNAC effectively segregates it from the rest of the network, mitigating potential risks while allowing for further investigation or remediation steps.

Based on the ZTNA logs provided, the true statement is:

A) The Remote_user ZTNA tag has matched the ZTNA rule: The log includes a user tag 'ztna_user' and a policy name 'External_Access_FAZ', which suggests that the ZTNA tag for 'Remote_User' has successfully matched the ZTNA rule defined in the policy to allow access.

The other options are not supported by the information in the log:

B) An authentication scheme is configured: The log does not provide details about an authentication scheme.

C) The external IP for ZTNA server is 10.122.0.139: The log entry indicates 'dstip=10.122.0.139' which suggests that this is the destination IP address for the traffic, not necessarily the external IP of the ZTNA server.

D) Traffic is allowed by firewall policy 1: The log entry 'policyid=1' indicates that the traffic is matched to firewall policy ID 1, but it does not explicitly state that the traffic is allowed; although the term 'action=accept' suggests that the action taken by the policy is to allow the traffic, the answer option D could be considered correct as well.
