Understanding ZTNA:

Zero Trust Network Access (ZTNA) requires defining tags for identifying and managing endpoint access.

Evaluating Components:

FortiClient EMS is responsible for managing and defining ZTNA tag information within the Security Fabric.

Conclusion:

The correct component that defines ZTNA tag information in the Security Fabric integration is FortiClient EMS.

ZTNA and FortiClient EMS configuration documentation from the study guides.

Requirement:

The administrator needs to add an authentication server on FortiClient EMS in a different security zone that cannot allow a direct connection.

Solution Analysis:

The goal is to securely connect FortiClient EMS and the Active Directory server despite being in different security zones.

Evaluating Options:

Installing FortiClient EMS on the same VM as Active Directory (option B) is not practical due to security zone separation.

Configuring a slave FortiClient EMS on a virtual machine (option C) does not address the need for secure communication.

Configuring an Active Directory connector (option D) may not be sufficient without secure routing.

Conclusion:

Deploying a FortiGate device between FortiClient EMS and the Active Directory server ensures secure and controlled access between the two zones.
