A. Configure the Auto Scaling group with the VPC ID in which instances will be launched.
B. Configure the Auto Scaling Launch configuration with multiple subnets of the VPC to enable the Multi AZ feature.
C. Configure the Auto Scaling Launch configuration which does not allow assigning a public IP to instances.
D. Configure the Auto Scaling Launch configuration with the VPC security group.

Correct Answer: B

Explanation:

Explanation: The Amazon Virtual Private Cloud (Amazon VPC) allows the user to define a virtual networking environment in a private, isolated section of the Amazon Web Services (AWS) cloud. The user has complete control over the virtual networking environment. Within this virtual private cloud, the user can launch AWS resources, such as an Auto Scaling group. Before creating the Auto Scaling group it is recommended that the user creates the Launch configuration.
Since it is a VPC, it is recommended to select the parameter which does not allow assigning a public IP to the instances. The user should also set the VPC security group with the Launch configuration and select the subnets where the instances will be launched in the AutoScaling group. The HA will be provided as the subnets may be a part of separate AZs.
