Your company is planning to establish a virtual private cloud (VPC) network and aims to configure a single subnet within this VPC to utilize the maximum range of available IP addresses. Which CIDR block would you recommend for this purpose?

Real Exam

Explanation:

The correct answer is B (10.0.0.0/8) because it allows for the maximum number of private IP addresses within a VPC, offering up to 16,777,212 available IPs. This is one of the standard private CIDR blocks recommended for VPCs.

192.168.0.0/16 provides 65,532 IPs.
172.16.0.0/12 offers 1,048,572 IPs.
0.0.0.0/0 is not a valid RFC 1918 CIDR range for a VPC.

Options A, C, and D are incorrect as they either provide fewer IPs or are not permissible for VPC configurations.
