A network access control list (ACL) is an optional layer of security for your VPC that acts as a firewall for controlling traffic in and out of one or more subnets.

Plz help!!!! my exam is near. are these questions enough for the exam?
This page (link above) has 400+ questions and thanks to all who’ve been posting questions and comments, there are multiple links in response to many questions.
I believe if you have gone through all the 400+ questions and visited the links to reinforce your u/standing of that concept, you should be good.
One of my colleague used this page on ‘briefmenow.org’ and passed (AWS-SAA) exam.
He informed about 10-15 questions were from here.
