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

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

Show Suggested Answer

Suggested Answer: A 🗳️
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.

I agree with A but the user would need to add inbound rules to the security group too ? by default by connecting just IG with the route table would only all the instance to connect to the internet but not the other way round. hmmm
