As a Google Associate Cloud Engineer, you are tasked with creating a custom Virtual Private Cloud (VPC) on Google Cloud. This VPC should contain only one subnet, and the IP address range for this subnet should be maximized to the largest possible size. Which CIDR range should you select for this subnet?
A
0.0.0.0/0
B
10.0.0.0/8
C
172.16.0.0/12
D
192.168.0.0/16
Explanation:
The correct answer is B, 10.0.0.0/8. This is because the /8 in 10.0.0.0/8 denotes that only the first 8 bits are reserved for identifying the network part of the address. The remaining 24 bits are available for host addresses within the network, making this the largest possible range. Option A (0.0.0.0/0) is invalid as it represents all possible IP addresses. Options C (172.16.0.0/12) and D (192.168.0.0/16) have more bits reserved for the network part, resulting in fewer host addresses within the network.
