A. Amazon VPC internet gateway: An internet gateway allows traffic to flow between the VPC and the internet. By attaching an internet gateway to the VPC and configuring the appropriate route in the route table, the subnet can be made publicly accessible.
C. Amazon VPC route tables: Route tables control the traffic flow within a VPC. To make the subnet public, the company needs to associate a route table with the subnet and add a route to the internet gateway in the route table.
A and C.To make a subnet public in a VPC, the company needs to do the following:
1.Attach an Internet Gateway to the VPC.
2. Create a public route in the route table of the subnet that points to the Internet Gateway.
Therefore, the company should use Amazon VPC Internet Gateway and Amazon VPC route tables to make the subnet public.
Amazon VPC NAT gateway is used to enable instances in a private subnet to connect to the Internet, while Amazon VPC network ACL and Amazon EC2 security groups are used for network security.
To make a subnet public in AWS, the following two features should be used:
A. Amazon VPC internet gateway: An internet gateway is used to enable communication between instances in the VPC and the internet. By attaching an internet gateway to a VPC and updating the route tables, instances in the subnet can access the internet.
C. Amazon VPC route tables: A route table controls the traffic between subnets and between a subnet and the internet. By adding a route to the internet gateway, the instances in the subnet can access the internet.
Therefore, options A and C are correct.
