You are trying to implement the below architecture.
So you have a VPC peering connection between VPC A and VPC C and another one between VPC B and VPC
C.You have Instances defined in each subnet, as shown above. You need to ensure the following.
· Instance i3 can communicate with Instance i1 but not Instance i2
· Instance i4 can communicate with Instance i2 but not Instance i1
What needs to be done so that this can accomplish? Choose 2 answers from the options given below.

Answer options:

A.Create 2 subnets in VPC C, ensure i3 and i4 are in different subnets.
B.Ensure different route tables are created to restrict access and added to the 2 different subnets.
C.Ensure that i3 and i4 are created in the same subnet.
D.Ensure that one route table is created which restricts access and added to the subnet.

Answer – A and B
Since VPC A and VPC B have overlapping CIDRs, it will be difficult to restrict traffic if you have only one subnet. Hence create two subnets with 2 different route tables will help meet the requirement.
Options C and D are incorrect since having one subnet will not help meet the requirement.
