A user has created a VPC with a subnet and a security group. The user has launched an instance
in that
subnet and attached a public IP. The user is still unable to connect to the instance. The internet
gateway has also been created. What can be the reason for the error?

A.
The internet gateway is not configured with the route table

B.
The private IP is not present

C.
The outbound traffic on the security group is disabled

D.
The internet gateway is not configured with the security group

Explanation:
A Virtual Private Cloud (VPC. is a virtual network dedicated to the user’s AWS account. AWS
provides two features the user can use to increase security in VPC: security groups and network
ACLs. Security groups work at the instance level. When a user launches an instance and wants to
connect to an instance, he needs an internet gateway. The internet gateway should be configured
with the route table to allow traffic from the internet.
