A development team has an application in a development VPC with CIDR 192.168.0.0/24. You must create a new VPC in the same account and peer it with the development VPC. What is the SMALLEST CIDR block you can assign to the new VPC that is valid for a VPC peering connection to the development VPC?

Correct answer: 10.0.1.0/24.
Why this is the answer
The correct answer is 10.0.1.0/24 because VPC peering connections do not allow overlapping CIDR blocks. The development VPC uses 192.168.0.0/24, so any CIDR block for the new VPC must not overlap with this range. 10.0.1.0/24 is a valid, non-overlapping private IP range. 10.0.1.0/32 is incorrect because a /32 CIDR block represents a single IP address, which is too small for a VPC. 192.168.0.0/24 is incorrect because it is the exact same CIDR block as the development VPC, leading to an overlap, which is not allowed for VPC peering. 192.168.1.0/32 is incorrect for two reasons: it's a /32 (single IP) and it overlaps with the broader 192.168.0.0/16 range, which is often considered when planning VPCs to avoid future conflicts, though the immediate conflict here is with 192.168.0.0/24.
