AWS Certified Advanced Networking - Specialty (#64)

Refer to the image.

You have three VPCs: A, B, and C. VPCs A and C are both peered with VPC B. The IP address ranges are as follows:

VPC A: 10.0.0.0/16

VPC B: 192.168.0.0/16

VPC C: 10.0.0.0/16

Instance i-1 in VPC A has the IP address 10.0.0.10. Instance i-2 in VPC C has the IP address 10.0.0.10. Instances i-3 and i-4 in VPC B have the IP addresses 192.168.1.10 and 192.168.1.20, respectively, i-3 and i-4 are in the subnet 192.168.1.0/24.

i-3 must be able to communicate with i-1

i-4 must be able to communicate with i-2

i-3 and i-4 are able to communicate with i-1, but not with i-2.

Which two steps will fix this problem? (Select two.)

Create subnets 192.168.1.0/28 and 192.168.1.16/28. Move i-3 and i-4 to these subnets, respectively.
Create subnets 192.168.1.0/27 and 192.168.1.16/27. Move i-3 and i-4 to these subnets, respectively.
Change the IP address of i-2 to 10.0.0.100. Assign it an elastic IP address.
Create a new route table for VPC B, with unique route entries for destination VPC A and destination VPC C.
Create two route tables: one with a route for destination VPC A, and another for destination VPC C.
