A user has created a VPC with CIDR 20.0.0.0/16. The user has created one subnet with CIDR 20.0.0.0/16 in this VPC. The user is trying to create another subnet with the same VPC for CIDR 20.0.0.1/24.

What will happen in this scenario?
Designing highly available, cost-efficient, fault-tolerant, scalable systems Designing enterprise-wide scalable operations on AWS
A user has created a VPC with CIDR 20.0.0.0/16 using the VPC wizard. The user has created public and VPN only subnets along with hardware VPN access to connect to the user's data center. The user has not yet launched any instance as well as modified or deleted any setup. He wants to delete this VPC from the console.

Will the console allow the user to delete the VPC?

A user has created a VPC with CIDR 20.0.0.0/16 using the wizard. The user has created a public subnet CIDR (20.0.0.0/24) and VPN only subnets CIDR (20.0.1.0/24) along with the VPN gateway (vgw-123456) to connect to the user's data center. The user's data center has CIDR 172.28.0.0/12. The user has also setup a NAT instance (i-123456) to allow traffic to the internet from the VPN subnet.

Which of the below mentioned options is not a valid entry for the main route table in this scenario?

A user has created a VPC with public and private subnets. The VPC has CIDR 20.0.0.0/16. The private subnet uses CIDR 20.0.1.0/24 and the public subnet uses CIDR 20.0.0.0/24. The user is planning to host a web server in the public subnet (port 80) and a DB server in the private subnet (port 3306). The user is configuring a security group of the NAT instance.

Which of the below mentioned entries is not required in NAT's security group for the database servers to connect to the Internet for software updates?
