Hello Jonathan,
Thank you for your reply.
You can have many NACLs and many route tables. Just because one NACL is wrong doesn’t mean that NACL is applied to all subnets.
>> Yes, but I think by default it is safer to assume that the NACL is applied to all subnets in the VPC if nothing is stated in the question. If the NACL is applied to particular subnets only, I think AWS questions will mention that particular detail.
The default VPC which has 3 default subnets has the NACL applied to all subnets. This is a Professional level question and I believe we have to make implied judgments or assumptions that are not explicitly specified. As for NACLs, I assume they are applied to all subnets in the VPC unless otherwise specified in the question.
Hope this helps.
