Explanation: The Junos OS achieves high availability on Junos security platforms using chassis clustering. Chassis clustering provides network node redundancy by grouping two like devices into a cluster. The two nodes back each other up with one node acting as the primary and the other as the secondary node, ensuring the stateful failover of processes and services in the event of system or hardware failure. A control link between services processing cards (SPCs) or revenue ports and an Ethernet data link between revenue ports connect two like devices.
