Question #: 15
Topic #: 3

The application placement controller has been configured with elasticity mode enabled. Intermittently, all instances of a dynamic cluster are removed. After further review, the system administrator noticed that it occurs during peak load on another dynamic cluster.

The administrator wants to keep at least one instance available. Which configuration is needed in the dynamic clusters?

AEnable application lazy start with elasticity mode.

BSet the proactiveIdleStop custom property to true.

CSet the Number of instances to a value greater than zero.

DDisable the option ''If other dynamic clusters need resources, stop all instances of this cluster during periods of inactivity''.

Show Suggested Answer

Suggested Answer: D

It is not recommended to enable elasticity mode when the following option is set in the administrative console for one or more dynamic clusters:

If other dynamic clusters need resources, stop all instances of this cluster during periods of inactivity.

If you have elasticity mode enabled and the option set, the application placement controller can remove all of the custom nodes in the cell.
