An administrator decides to designate a node as the primary node for the chassis cluster. Which statement is correct in this scenario?

In a Junos OS chassis cluster, the primary node (also known as the master) is determined through an election process. The primary factor in this election is the configured priority value for each node, which ranges from 0 to 255. The node with the numerically highest priority value will be elected as the primary node, assuming it is healthy. If the priorities are identical (default is 128), other factors like uptime or manual failover commands are used as tie-breakers. A priority of 0 makes a node ineligible for mastership.

A. The burnt-in-address (BIA), which is a MAC address, is not used in the chassis cluster primary election process.

C. The node with the lowest priority value will become the backup (secondary) node, not the primary node.

D. A node with a priority of zero (0), not one (1), is ineligible to participate in the election process for primary.

Juniper Networks TechLibrary, "Understanding Chassis Cluster Control Link Heartbeats and Failure Detection". Under the "Chassis Cluster Mastership Election" section, it states, "The node with the higher priority value becomes the master."

Juniper Networks TechLibrary, "set chassis cluster redundancy-group 1 node 1 priority". The documentation for this command states, "Specify the priority of the node for the redundancy group... The node with the higher priority becomes the master. Range: 0 through 255." It also notes, "A priority of 0 means the node never becomes the master."
