A sys admin is maintaining an application on AWS. The application is installed on EC2 and user has configured ELB and Auto Scaling. Considering future load increase, the user is planning to launch new servers proactively so that they get registered with ELB.

Answers
C.
Launch an instance manually and register it with ELB on the fly
D.
Increase the desired capacity of the Auto Scaling group
Answers
D.
Increase the desired capacity of the Auto Scaling group
Suggested answer: D

Explanation:

A user can increase the desired capacity of the Auto Scaling group and Auto Scaling will launch a new instance as per the new capacity. The newly launched instances will be registered with ELB if Auto Scaling group is configured with ELB. If the user decreases the minimum size the instances will be removed from Auto Scaling. Increasing the maximum size will not add instances but only set the maximum instance cap.
