 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.

 With the increase in IoT devices, enterprises face many challenges in securing and managing their network and data. Two of the most significant challenges are:

• Unpatched vulnerabilities in IoT devices (Option C): IoT devices are often vulnerable to cyber attacks due to their increased exposure to the internet and their limited computing resources. Some of the security challenges in IoT include weak password protection, lack of regular patches and updates, insecure interfaces, insufficient data protection, and poor IoT device management12. Unpatched vulnerabilities in IoT devices can allow hackers to exploit them and compromise the network or data. For example, the Mirai malware infected IoT devices by using default credentials and created a massive botnet that launched DDoS attacks on internet services2.
• Achieving full network visibility (Option D): IoT devices can generate a large amount of data that needs to be collected, processed, and analyzed. However, many enterprises lack the tools and capabilities to monitor and manage the IoT devices and data effectively. This can result in poor performance, inefficiency, and security risks. Achieving full network visibility means having a clear and comprehensive view of all the IoT devices, their status, their connectivity, their data flow, and their potential threats. This can help enterprises optimize their network performance, ensure data quality and integrity, and detect and prevent any anomalies or attacks3.

According to the FortiNAC documentation1, disabled hosts are placed in the dead end VLAN, which is a special VLAN that isolates them from the production network. This is done to prevent unauthorized or compromised hosts from accessing network resources or spreading malware. The dead end VLAN must be configured in the AP model or the SSID configuration, and the state must be enforced23. Disabled hosts can be enabled again by the administrator or by reauthenticating through the FortiNAC portal. References := 1: Enable or disable hosts | FortiNAC 9.4.0 - Fortinet Documentation 2: Technical Tip: Disabled wireless hosts not isolated - FortiNAC 3: Technical Tip: Disabled wired hosts not isolated - FortiNAC
