Which of the following must be configured for the initial setup of FortiAnalyzer?

For the initial setup of FortiAnalyzer, configuring the management ports is essential. This step involves setting up the network interfaces that will allow administrators to access the FortiAnalyzer. Proper configuration of management ports ensures that the device can be reached over the network for administrative tasks, monitoring, and analysis. Access to these ports is critical for the setup process, as it is through them that the FortiAnalyzer is configured, managed, and monitored.

While backup configuration settings, global user policy, and VPN settings are important components of a fully functional FortiAnalyzer, they are not necessary for the initial setup. The management ports need to be configured first to allow for any further configurations to take place. Without this critical step, administrators would not be able to interact with the device to manage or analyze network data effectively.
