VLAN 1303 through a MikroTik router, the Agent-based Installer, LVMS for dynamic storage, and MetalLB for real LoadBalancer services. Why a real cluster? The EX280 is a hands-on exam. You sit at a workstation, you get a cluster, and you&rsquo;re judged on whether you can make it do what the question asked, with configurations that survive a full reboot.
