Topic 1 Question 296
A development team has launched a new application that is hosted on Amazon EC2 instances inside a development VPC. A solutions architect needs to create a new VPC in the same account. The new VPC will be peered with the development VPC. The VPC CIDR block for the development VPC is 192.168.0.0/24. The solutions architect needs to create a CIDR block for the new VPC. The CIDR block must be valid for a VPC peering connection to the development VPC.
What is the SMALLEST CIDR block that meets these requirements?
10.0.1.0/32
192.168.0.0/24
192.168.1.0/32
10.0.1.0/24

10.0.1.0/32 and 192.168.1.0/32 are too small for VPC, and /32 network is only 1 host 192.168.0.0/24 is overlapping with existing VPC

The allowed block size is between a /28 netmask and /16 netmask. The CIDR block must not overlap with any existing CIDR block that's associated with the VPC. https://docs.aws.amazon.com/vpc/latest/userguide/configure-your-vpc.html

• Option A (10.0.1.0/32) is invalid - a /32 CIDR prefix is a host route, not a VPC range. • Option B (192.168.0.0/24) overlaps the development VPC and so cannot be used. • Option C (192.168.1.0/32) is invalid - a /32 CIDR prefix is a host route, not a VPC range. • Option D (10.0.1.0/24) satisfies the non-overlapping CIDR requirement but is a larger block than needed. Since only two VPCs need to be peered, a /24 block provides more addresses than necessary.
