From the study guide: “If one server needs access to another server that resides in another subnet, you need to configure your main route table to connect these two subnets.”
I believe this is inaccurate, based on the following:
https://docs.aws.amazon.com/vpc/latest/userguide/configure-subnets.html
Subnet routing
Each subnet must be associated with a route table, which specifies the allowed routes for outbound traffic leaving the subnet. Every subnet that you create is automatically associated with the main route table for the VPChttps://docs.aws.amazon.com/vpc/latest/userguide/subnet-route-tables.html
Routes
Every route table contains a local route for communication within the VPC. This route is added by default to all route tables

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,
