A user has configured ELB with two EBS backed instances. The user has stopped the instances for 1 week to
save costs. The user restarts the instances after 1 week. Which of the below mentioned statements will help
the user to understand the ELB and instance registration better?

A.
There is no way to register the stopped instances with ELB

B.
The user cannot stop the instances if they are registered with ELB

C.
If the instances have the same Elastic IP assigned after reboot they will be registered with ELB

D.
The instances will automatically get registered with ELB

Explanation:
Elastic Load Balancing registers the user’s load balancer with his EC2 instance using the associated IP
address. When the instances are stopped and started back they will have a different IP address. Thus, they will
not get registered with ELB unless the user manually registers them. If the instances are assigned the same
Elastic IP after reboot they will automatically get registered with ELB.
