Your team is deploying a single FortiGate and a single FortiSwitch across 100 branch offices.

According to theFortiOS 7.6 Administration Guideand theFortiManager 7.6 Study Guide, the most efficient and scalable method for deploying standardized configurations across a high volume of sites (such as 100 branch offices) isZero-Touch Provisioning (ZTP) through FortiManager.

ZTP allows administrators to createModel DevicesandProvisioning Templateswithin FortiManager before the physical hardware is even unboxed. When a factory-reset FortiGate at a branch office is connected to the internet, it automatically reaches out toFortiCloud(FortiDeploy) to discover its assigned management entity. Once redirected to the centralFortiManager, the FortiGate retrieves its full configuration, including theFortiLinksettings required to manage the local FortiSwitch.

The 7.6 documentation highlights that because the FortiSwitch is managed via FortiLink, its configuration is technically part of the FortiGate ' s managed objects. Therefore, by using FortiManager to push a single template that includes both the FortiGate settings and theSwitch Controllerconfigurations, the team can ensure that every branch office is configured identically and without manual CLI intervention. This method significantly reduces the risk of human error and ensures rapid, consistent deployment across the entire fabric. Options A and B refer to cloud management platforms that are effective but do not offer the same level of integrated, template-driven orchestration for large-scale enterprise ZTP as FortiManager. Option D is incorrect as " FortiSwitch Manager " is not the primary orchestration tool for branch-wide ZTP in a FortiLink-integrated environment.
