A user has configured ELB with Auto Scaling. The user suspended the Auto Scaling AddToLoadBalancer
(which adds instances to the load balancer. process for a while. What will happen to the instances launched
during the suspension period?
A.
The instances will not be registered with ELB and the user has to manually register when the process
is resumed
B.
The instances will be registered with ELB only once the process has resumed
C.
Auto Scaling will not launch the instance during this period due to process suspension
D.
It is not possible to suspend only the AddToLoadBalancer process
Explanation:
Auto Scaling performs various processes, such as Launch, Terminate, add to Load Balancer etc. The user can
also suspend the individual process. The AddToLoadBalancer process type adds instances to the load
balancer when the instances are launched. If this process is suspended, Auto Scaling will launch the instances
but will not add them to the load balancer. When the user resumes this process, Auto Scaling will resume
adding new instances launched after resumption to the load balancer. However, it will not add running
instances that were launched while the process was suspended; those instances must be added manually.
A
“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.”
