Question about chapter 5 in Darril's book

Great book btw, Darril.

My question is about practice question #18.

18. What ports need to be open for a website hosting both encrypted and unencrypted internet traffic.

I knew those were ports 80 and 443. What I was confused about is this concept of inbound and outbound. I chose all four answers but the answer was only the inbound ports. Don't any outbound ports need to opened so the browser can request the website?

It will help make things easy if you think about it from the server's point of view. The server needs to accept inbound, in other words INCOMING traffic, going IN to the server.

Outbound traffic is when you are trying to connect the web server.

Going back to your original question:

What ports need to be open for a website hosting both encrypted and unencrypted internet traffic.

Since this is from the perspective of the server, the server has to be accepting incoming traffic (inbound) with the required ports.

Client goes OUT to INcoming server.

Hopefully that makes better sense.
