4. A EC2 instance should be created and all traffic should be forwarded to EC2 instance.


Ans : 3
Exp : Your VPC has an implied router ,
the VPC wizard creates a route table that routes all traffic destined for an address outside the VPC to the Internet gateway,
and associates this route table with the subnet. Otherwise, you'd need to create and associate the route table yourself.

The following table shows what the route table looks like for the example addresses used in the configuration diagram
for this scenario. The first row shows the entry for local routing in the VPC; this entry enables the instances in this VPC
to communicate with each other. The second row shows the entry for routing all other subnet traffic to the Internet gateway,
which is specified using its AWS-assigned identifier.

Destination 10.0.0.0/16 Target local
Destination 0.0.0.0/0 Target igw-xxxxxxxx
