Question #: 21
Topic #: 3
A customer’s infrastructure is set up to use both primary and secondary gateway clusters on the SSID profile cased on best practices. Why do they have an equal split of their 120 APs across the primary and secondary gateway clusters?
A.
The primary gateway cluster is a heterogeneous cluster with six nodes.
B.
The primary and secondary gateway clusters are up. and the cluster preemption is enabled
C.
The secondary gateway cluster is a homogeneous cluster with six nodes.
D.
The primary and secondary gateway clusters are up. but the cluster preemption Is not enabled
When cluster preemption is not enabled, access points (APs) will not automatically fail back to the primary gateway cluster once it is up again after having failed over to the secondary. This would result in an equal split of APs across primary and secondary clusters if both clusters are operational. Without preemption, there's no automatic rebalancing of APs back to the primary cluster, leading to the current distribution.
