A. They are stateless: Network ACLs do not maintain connection state information. Each packet is evaluated independently based on the rules defined in the ACL.
D. They process rules in order, starting with the lowest numbered rule, when deciding whether to allow traffic: Network ACLs evaluate rules sequentially from the lowest numbered rule to the highest numbered rule. Once a rule that matches the traffic is found, further rule processing stops.
Rule number. Rules are evaluated starting with the lowest numbered rule. As soon as a rule matches traffic, it's applied regardless of any higher-numbered rule that might contradict it.
NACLs are stateless, which means that information about previously sent or received traffic is not saved.

A. They are stateless.
D. They process rules in order, starting with the lowest numbered rule, when deciding whether to allow traffic.
Explanation:
A. Network ACLs (Access Control Lists) in AWS are stateless, meaning they do not keep track of the state of established connections. Each rule in a network ACL is applied independently of the others.
D. Network ACLs process rules in order, starting with the lowest numbered rule. Once a rule is matched, no further rules are evaluated, which makes the order of rules important.
The other options are not correct.
Network ACLs are stateless, meaning each packet is processed individually regardless of any previous packets, and they evaluate rules sequentially, starting from the lowest numbered rule.
They do not evaluate all rules before allowing traffic. They evaluate the rules in order, starting with the lowest numbered rule, when deciding whether allow or deny traffic. If the traffic matches a rule, the rule is applied and then they do not evaluate any additional rules. SO "C" can NOT be a correct answer.
