1. Each chassis cluster member requires a unique cluster ID value: This statement is true. Each chassis cluster member must have a unique cluster ID assigned, which is used to identify each device in the cluster.
2. Each chassis cluster member device can host active redundancy groups: This statement is true. Both devices in a chassis cluster can host active redundancy groups, allowing for load balancing and failover capabilities.
The two statements about SRX Series device chassis clusters that are true are that each chassis cluster member requires a unique cluster ID value, and that each chassis cluster member device can host active redundancy groups. A unique cluster ID value is necessary so that all members of the cluster can be identified, and each chassis cluster member device can host active redundancy groups to ensure that the cluster is able to maintain high availability and redundancy. Additionally, it is not necessary for all chassis cluster member devices to be the same model, as long as all devices are running the same version of Junos software.
