You are asked to configure a FortiSandbox HA cluster.

The Study Guide states that HA is configured from the CLI and that “the main HA cluster CLI commands are hc-settings, hc-slave, and hc-status” . It also explains that “You use the hc-settings command and options to configure the main HA settings… node alias, group name, group password, and the HA interface.” The same HA section further says that the primary and secondary nodes must have a dedicated HA communication interface, and specifically notes that “port4 in this example” is the HA interface between them.

On the primary-node example configuration shown on page 137 of the uploaded study guide, the command uses -tM for the primary node with -iport4 for the HA interface. That directly matches option D . The other options use different node-type flags and do not correspond to the primary-node example. Therefore, the correct command is hc-settings -sc -tM -nPrimaryNode -cFSAGrp -p < password > -iport4 .
