AWS Certified SysOps Administrator SOA-C01 – Question274 - AWS Certified SysOps Administrator SOA-C01

A user has created a VPC with public and private subnets using the VPC wizard. Which of the below mentioned statements is true in this scenario?

A. The AWS VPC will automatically create a NAT instance with the micro size
B. VPC bounds the main route table with a private subnet and a custom route table with a public subnet
C. The user has to manually create a NAT instance
D. VPC bounds the main route table with a public subnet and a custom route table with a private subnet

Correct Answer: B

Explanation:

Explanation: A Virtual Private Cloud (VPC) is a virtual network dedicated to the user’s AWS account. 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 a NAT instance of a smaller or higher size, respectively. The VPC has an implied router and the VPC wizard updates the main route table used with the private subnet, creates a custom route table and associates it with the public subnet.
