Explanation

An Internet Gateway (IGW) is the VPC component that enables direct internet access for EC2 instances - it acts as the bridge between your VPC and the public internet, handling both inbound and outbound traffic when attached to a VPC and referenced in a route table.

Why the distractors are wrong:

• B. Transit Gateway - connects multiple VPCs and on-premises networks together, not a path to the public internet on its own.
• C. Virtual Private Gateway - the VPN endpoint on the AWS side for connecting your VPC to an on-premises network via a VPN tunnel, not the internet.
• D. Customer Gateway - represents your on-premises VPN device in AWS's configuration; it's the other half of a VPN connection, not an internet access point.

Memory tip: Think of the Internet Gateway like your home router's WAN port - it's the single attachment point that "opens" your private network to the internet. The word "Internet" is literally in the name, which makes A the obvious answer when the question asks about internet access.
