NSE7_ZTA-7.2 Sample Questions Answers

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.References:FortiGate Security 7.2 Study Guide, LDAP Authentication configuration sections.

To prevent direct host-to-host communication at layer 2 and use only FortiGate to inspect all the VLAN traffic, an administrator must configure:

• B. Block intra-VLAN traffic in the VLAN interface settings: This setting prevents direct communication between hosts within the same VLAN, forcing traffic to be routed through FortiGate for inspection.
• D. Configure static routes to allow subnets: By setting up static routes, the administrator ensures that traffic between different subnets is correctly routed through the FortiGate for inspection and policy enforcement.
• E. Configure a firewall policy to allow the desired traffic between hosts: Firewall policies on the FortiGate will dictate what traffic is permitted between hosts, ensuring that only authorized traffic is allowed.

The other options are not typically required for this setup:

• A. Configure proxy ARP to allow traffic: Proxy ARP is not necessary for this scenario as it involves answering ARP requests on behalf of another host, which is not relevant to blocking intra-VLAN traffic.
• C. Add the VLAN interface to a software switch: This would create a switch-like environment on the FortiGate, which is counterproductive to the goal of preventing direct host-to-host communication at layer 2.

The FortiAnalyzer playbook configuration shown in the exhibit indicates that:

• D. The playbook is manually started by an administrator: The "ON DEMAND" trigger in the playbook suggests that it is initiated manually, as opposed to being automated or scheduled. This typically means that an administrator decides when to run the playbook based on specific needs or incidents.

In a ZTNA (Zero Trust Network Access) deployment, FortiClient EMS:

• A. Uses endpoint information to grant or deny access to the network: FortiClient EMS plays a critical role in ZTNA by using information about the endpoint, such as its security posture and compliance status, to determine whether to grant or deny network access.

The other options do not accurately represent the role of FortiClient EMS in ZTNA:

• B. Provides network and user identity authentication services: While it contributes to the overall ZTNA strategy, FortiClient EMS itself does not directly provide authentication services.
• C. Generates and installs client certificates on managed endpoints: Certificate management is typically handled by other components in the ZTNA framework.
• D. Acts as ZTNA access proxy for managed endpoints: FortiClient EMS does not function as an access proxy; its role is more aligned with endpoint management and policy enforcement.

In FortiNAC, to isolate rogue hosts, you should enable the:

• C. Forced Remediation: This port group membership is used to isolate hosts that have been determined to be non-compliant or potentially harmful. It enforces a remediation process on the devices in this group, often by placing them in a separate VLAN or network segment where they have limited or no access to the rest of the network until they are remediated.

The other options are not specifically designed for isolating rogue hosts:

• A. Forced Authentication: This is used to require devices to authenticate before gaining network access.
• B. Forced Registration: This group is used to ensure that all devices are registered before they are allowed on the network.
• D. Reset Forced Registration: This is used to reset the registration status of devices, not to isolate them.

For on-fabric clients to access FortiAnalyzer using ZTNA tags, the following conditions must be met:

• A. The on-fabric client should have FortiGate as its default gateway: This is essential to ensure that all client traffic is routed through FortiGate, where ZTNA policies can be enforced.
• B. The ZTNA server must be configured on FortiGate: For ZTNA tags to be effectively used, the ZTNA server, which processes and enforces these tags, must be configured on the FortiGate appliance.
