Question
Which two statements are correct about chassis clustering? (Choose two.)
A. The node ID value ranges from 1 to 255.
B. The node ID is used to identify each device in the chassis cluster.
C. A system reboot is required to activate changes to the cluster ID.
D. The cluster ID is used to identify each device in the chassis cluster.
Answer
B. The node ID is used to identify each device in the chassis cluster.
C. A system reboot is required to activate changes to the cluster ID.
Explanation
In Juniper chassis clustering, there are two important identifiers: the node ID and the cluster ID.
The node ID is used to uniquely identify each device within a chassis cluster. It is a number assigned to each member of the cluster, allowing the system to distinguish between the devices. However, the node ID value range is not from 1 to 255, as stated in option A. The correct range for the node ID is from 0 to 1, with 0 typically representing the primary node and 1 representing the secondary node.
The cluster ID, on the other hand, is used to identify the entire chassis cluster as a single entity. It is a shared value among all devices in the cluster, indicating that they belong to the same group. Unlike the node ID, which identifies individual devices, the cluster ID represents the cluster as a whole.
When making changes to the cluster ID, a system reboot is required for the changes to take effect. This ensures that all devices in the cluster are properly synchronized with the new cluster ID value.
In summary, the node ID identifies each device within a chassis cluster (answer B), while the cluster ID identifies the entire cluster. Additionally, a system reboot is necessary to activate changes made to the cluster ID (answer C).
