Your VPC currently has 2 subnets in AWS. The VPC has a CIDR block of 10.0.0.0/16 and the subnets have a CIDR block of 10.0.1.0/24 and 10.0.2.0/24 respectively. You decide on creating a custom route table for each subnet. When you initially create a custom route table , which of the following routes will be present in the route table automatically,

Answer options:

A.A route for 10.0.0.0/16 as the destination
B.A route for 10.0.1.0/24 as the destination
C.A route for 10.0.2.0/24 as the destination
D.There will be no default route in the route table

Answer – A
By default when the new route table is created , it will have a default route for the CIDR block of the VPC.The AWS documentation mentions the following
Every route table contains a local route for communication within the VPC over IPv4. If your VPC has more than one IPv4 CIDR block, your route tables contain a local route for each IPv4 CIDR block. If you`ve associated an IPv6 CIDR block with your VPC, your route tables contain a local route for the IPv6 CIDR block. You cannot modify or delete these routes
