Which three statements are true concerning the behavior of an Oracle Clusterware 12c Flex Cluster in response to hub or leaf node failures? (Choose three.)
A.
Leaf nodes evicted from a Flex Cluster always require a reboot.
B.
Hug node eviction results in the reboot of all leaf nodes that were connected to the evicted hub node.
C.
Hub nodes evicted from a Flex Cluster always require a reboot.
D.
Hub node eviction results in the eviction of all leaf nodes that were connected to the evicted hub node.
E.
Cluster Resources on a leaf node that is evicted from a Flex Cluster are relocated, if possible, to another leaf node that is connected to same hub node to which the failed leaf node was connected.
F.
Cluster Resources on a hub node that is evicted from a Flex Cluster are always relocated to a leaf node that was connected to the evicted hub node.
G.
Cluster Resources on a hub node that is evicted from a Flex Cluster are always relocated to another hub node in the cluster.
Not A, B, C: Nodes that are evicted from the cluster do not require a restart; they need only a cluster software restart.
Yes D: If Hub Node fails: Corresponding Leaf Nodes are also evicted from the cluster
Yes E: …the cluster attempts to relocate services running on the Leaf Node to other Leaf Nodes connected to the same Hub Node.
Not F, yes G: If a Hub Node fails: The node is evicted from the cluster. Services are relocated to other Hub Node if possible.
