Which of the following statements are true about the default Network ACL assigned to the default VPC.

Answer options:

A.The Network ACL Inbound Rules allow all traffic
B.The Network ACL Inbound Rules deny all traffic
C.The Network ACL Outbound Rules allow all traffic
D.The Network ACL Outbound Rules deny all traffic

Answer – A and C
The AWS documentation mentions the following
The default network ACL is configured to allow all traffic to flow in and out of the subnets to which it is associated. Each network ACL also includes a rule whose rule number is an asterisk. This rule ensures that if a packet doesn`t match any of the other numbered rules, it`s denied. You can`t modify or remove this rule.
