Which network allows devices to communicate without the need to access the Internet?

Answer options

• A. 172.9.0.0/16
• B. 172.28.0.0/16
• C. 192.0.0.0/8
• D. 209.165.201.0/24

Correct answer: B

Explanation

The correct answer is B, as the 172.28.0.0/16 network is part of the private IP address range that allows internal communication without Internet access. Options A, C, and D are either public IP addresses or do not belong to the private IP address ranges, thus requiring Internet access for communication.
