Explanation

To create three subnets with at least 30 hosts each: Subnet Calculation: Each subnet must support 32 addresses (30 usable + 2 reserved for network Bits for Subnets: Subnet mask 255.255.255.192 (/26) provides 64 addresses per subnet (4 Valid Subnets: Each subnet provides sufficient IPs to meet the requirement.
