Which of the following statements on VPC routing is false.
Click on the arrows to vote for the correct answer
A. B. C. D.Answer - B.
The AWS documentation mentions the following on Route tables.
The following are the basic things that you need to know about route tables:
· Your VPC has an implicit router.
· Your VPC automatically comes with a main route table that you can modify.
· You can create additional custom route tables for your VPC.· Each subnet must be associated with a route table, which controls the routing for the subnet.
If you don't explicitly associate a subnet with a particular route table, the subnet is implicitly associated with the main route table.
· You cannot delete the main route table, but you can replace the main route table with a custom table that you've created (so that this table is the default table each new subnet is associated with).

Explanation:
A. The VPC comes with an implicit router: When you create a VPC, a router is automatically created and it is the main router for the VPC. It handles all the traffic going in and out of the VPC.
B. You can delete the main route table with the VPC and replace it with a custom route table: This statement is false. The main route table is automatically created when you create a VPC and it cannot be deleted. However, you can create custom route tables and associate them with subnets in the VPC.
C. You can create additional custom route tables for your VPC: Yes, you can create additional custom route tables for your VPC. This allows you to have more granular control over the routing of traffic within your VPC.
D. Each subnet in a VPC must be associated with a route table: Yes, each subnet in a VPC must be associated with a route table. When you create a subnet, you must specify which route table it should use.
In summary, the false statement is B. You cannot delete the main route table with the VPC and replace it with a custom route table.
