That makes sense, VPC Subnet could be the solution to the problem.

D. Internet Gateway, no doubt about it. How else is that web server gonna receive incoming traffic?

Haha, I bet the engineer just forgot to pay the internet bill. Nah, just kidding. I'm going with D. Internet Gateway, that's gotta be it.

I think the answer is A) VPC Subnet because it controls the traffic flow between the web server and the internet.

This one's tricky, but I think C. Network Security Group is the way to go. Gotta make sure the firewall rules are set up correctly, right?

So, we need both Network Security Group and Internet Gateway to solve the issue.

You're right, an Internet Gateway is needed for external communication.

But don't we also need an Internet Gateway to allow incoming traffic to the web server?

But NAT Gateway allows the server to connect to the internet, not receive incoming traffic.

Hmm, I'm leaning towards B. NAT Gateway. Isn't that used to allow instances in a private subnet to access the internet?

Agreed, NAT Gateway is the solution to allow the web server to receive incoming traffic while still connecting to the internet.

Yes, NAT Gateway is the correct choice for allowing outgoing internet traffic from private subnets.

I'm pretty sure the answer is D. Internet Gateway. Without that, the server can't receive incoming traffic, even if it can connect to the internet.

Got it. So, the Internet Gateway is the missing piece to allow incoming traffic to the web server in AWS.

The VPC Subnet, NAT Gateway, and Network Security Group are important, but in this case, the Internet Gateway is the key.
