You have provisioned a custom VPC with a subnet that has a CIDR block of 10.0.3.0/28 address range. Inside this subnet, you have 2 webservers, 2 application servers, 2 database servers, and a NAT. You have configured an Autoscaling group on the two web servers to automatically scale when the CPU utilization goes above 90%. Several days later you notice that autoscaling is no longer deploying new instances into the subnet, despite the CPU utilization of all web servers being at 100%. Which of the following answers may offer an explanation?
a. AWS reserves both the first four and the last IP address in each subnet's CIDR block.
b. Your Autoscaling Group (ASG) has provisioned too many EC2 instances and has exhausted the number of internal IP addresses available in the subnet.
c. Your internet gateway (IGW) on your VPC has provisioned too many EC2 instances.
d. AWS reserves both the first two and the last two IP addresses in each subnet's CIDR block.
e. AWS reserves both the first three and the last two IP addresses in each subnet's CIDR block.
