Show Suggested Answer

Suggested Answer: A 🗳️
A user can create a subnet with VPC and launch instances inside that subnet. If the user has created a public private subnet, the instances in the public subnet can receive inbound traffic directly from the Internet, whereas the instances in the private subnet cannot. If these subnets are created with Wizard, AWS will create two route tables and attach to the subnets. The main route table will have the entry ג€Destination: 0.0.0.0/0 and Target: ia12345ג€, which allows all the instances in the private subnet to connect to the internet using NAT.
