Which of the following are features of network ACLs as they are used in the AWS Cloud? (Choose two)
A) They are stateless.
B) They are stateful.
C) They evaluate all rules before allowing traffic.
D) They process rules in order, starting with the lowest numbered rule, when deciding whether to allow traffic.
E) They operate at the instance level.
Solution
Correct answer: A) They are stateless and D) They process rules in order, starting with the lowest numbered rule, when deciding whether to allow traffic.
Network ACLs (Access Control Lists) in AWS:
A - Meaning they do not keep track of the state of a connection. Each packet is evaluated independently based on the rules.
D - This sequential evaluation of rules is a key aspect of how Network ACLs work in AWS.
Network ACLs are associated with subnets and provide a basic form of security control by filtering traffic in and out of subnets based on rules defined within them. They are evaluated in a sequential manner based on rule number, without considering the state or context of the traffic.
