Hello tugjg,
Thank you for pointing this out and for sharing the AWS documentation references. You’re right, communication between subnets within the same VPC is automatically enabled by the default local route in every route table. There’s no need to configure the main route table for basic inter-subnet communication manually.
We sincerely apologize for the confusion caused by the statement in the study guide. We acknowledge this discrepancy and will update the eBook to reflect the correct information in line with the AWS documentation you’ve shared.
Your attention to detail helps us improve the accuracy of our materials, and we genuinely appreciate you taking the time to bring this up.
Cheers,
Nikee @ Tutorial Dojo
