Multiple Choice

A company recently launched Linux-based application instances on Amazon EC2 in a private subnet and launched a Linux-based bastion host on an Amazon EC2 instance in a public subnet of a VPC.

Which combination of steps should the solutions architect take to meet these requirements? (Choose two.)

• A) Replace the current security group of the bastion host with one that only allows inbound access from the application instances.
• B) Replace the current security group of the bastion host with one that only allows inbound access from the internal IP range for the company.
• C) Replace the current security group of the bastion host with one that only allows inbound access from the external IP range for the company.
• D) Replace the current security group of the application instances with one that allows inbound SSH access from only the private IP address of the bastion host.
