The RDS database instance should accept traffic onlyfrom the EC2 instances in the Auto Scaling group.What should be done to meet these requirements?
A. Configure the inbound network ACLs on the database subnet to accept traffic fromthe IP addresses of the EC2 instances only.
B. Configure the inbound rules on the security group associated with the RDS databaseinstance. Set the source to the security group associated with instances in the Auto
Scaling group.
C. Configure the outbound rules on the security group associated with the Auto Scalinggroup. Set the destination to the security group associated with the RDS databaseinstance.
D. Configure the inbound network ACLs on the database subnet to accept traffic onlyfrom the CIDR range of the subnet used by the Auto Scaling group.
