問題文
A team that has only operated chassis clusters is reviewing a Multinode High Availability design for two SRX Series Firewalls. Before writing the maintenance procedure, they ask how the two firewalls divide the active and the backup role between them. Which statement describes how roles are assigned in this solution?
選択肢
- The node with the lower node identifier becomes the primary for the whole system when the pair boots, and it keeps that role until it is rebooted or an operator requests a failover to the peer.
- Activeness is decided per services redundancy group rather than per node, so one node can hold the active SRG1 while SRG0 stays active on both nodes at the same time.
- The node that holds the active Routing Engine, as RG0 does in a chassis cluster, holds the primary role for the whole chassis, and the peer keeps its routing process idle until Junos OS moves that role over to it.
- Roles are assigned per revenue interface, and each interface elects its owner from the two nodes, so both firewalls can hold the primary role at the same time for different parts of the topology.
