C is correct you connect to the console port on the primary device, give it a node ID, and identify the cluster it will belong to, and then reboot the system. You then connect the console port to the other device, give it a node ID, and assign it the same cluster ID you gave to the first node, and then reboot the system. In both instances, you can cause the system to boot automatically by including the reboot parameter in the CLI command line.

C is correct

In a Juniper Networks chassis clustering setup, when you enable chassis clustering on two devices and assign a cluster ID and a node ID to each device, the correct order for rebooting the devices is: C. Reboot the primary device, then the secondary device. Explanation: After assigning the cluster ID and node ID to each device, it is a good practice to reboot the primary device first. This ensures that the primary device comes online with the specified cluster and node IDs. Once the primary device is up and running, you can then reboot the secondary device. The secondary device will recognize the existing cluster and node IDs assigned to the primary device and join the cluster accordingly. So, the correct sequence is to reboot the primary device first and then the secondary device to establish the chassis cluster in the desired configuration. Option A is incorrect because the secondary device should be rebooted after the primary device. Options B and D are not accurate because both devices need to be rebooted, and the order is important for proper clustering.
