When Rebalancing, Auto Scaling Launches New Instances Before Terminating the Old

Multiple Choice

When rebalancing, Auto Scaling launches new instances before terminating the old ones, so that re-balancing does not compromise the performance or availability of your application. Because Auto Scaling attempts to launch new instances before terminating the old ones, being at or near the speci-fied maximum capacity could impede or completely halt rebalancing activities. What does Auto Scaling do in order to avoid this problem?

A) It can temporarily exceed the specified maximum capacity of a group by a 20 percent margin (or by a 2-instance margin, whichever is greater) during a rebalancing activity.
B) It can add new reserved instances you have defined.
C) It can temporarily exceed the specified maximum capacity of a group by a 10 percent margin (or by a 1-instance margin, whichever is greater) during a rebalancing activity.
D) It can temporarily exceed the specified maximum capacity of a group by a 5 percent margin (or by a 1-instance margin, whichever is greater) during a rebalancing activity.
