You have an Auto Scaling group with an Elastic Load Balancer. You decide to suspend the Auto Scaling AddToLoadBalancer for a short period of time. What will happen to the instances launched during the suspension period?

Answer options:

A.The instances will be registered with ELB once the process has resumed.
B.Auto Scaling will not launch the instances during this period because of the suspension.
C.The instances will not be registered with ELB. You must manually register when the process is resumed.
D.It is not possible to suspend the AddToLoadBalancer process.

Answer - C
If you suspend AddToLoadBalancer, Auto Scaling launches the instances but does not add them to the load balancer or target group. If you resume the AddToLoadBalancer process, Auto Scaling resumes adding instances to the load balancer or target group when they are launched. However, Auto Scaling does not add the instances that were launched while this process was suspended. You must register those instances manually.
