A user has created a VPC with the public

A. It can connect to the AWS services, such as S3 and RDS by default

B. It will have all the inbound traffic b

y default

C. It will have all the outbound traffic by default

D. It will by default allow traffic to the internet gateway

Explanation:

A Virtual Private Cloud (VPC) is a virtual network dedicated to the user-s AWS account. AWS provides two fe

atures the user can use to increase security in VPC: security groups and network ACLs. Security groups work at the instance level while ACLs work at the subnet level. When a user creates a security group with AWS VPC, by default it will allow all the outbo

und traffic but block all inbound traffic.
