CCNA: Cisco Certified Network Associate — Question 1113

What is a characteristic of private IPv4 addressing?

Answer options

• A. is used when the ISP requires the new subnet to be advertised to the internet for web services
• B. provides unlimited address ranges
• C. is used when the network has multiple endpoint listeners
• D. is used on hosts that communicate only with other internal hosts

Correct answer: D

Explanation

The correct answer is D, as private IPv4 addresses are specifically meant for communication between devices within the same internal network, not accessible from the public internet. Option A is incorrect because private addresses are not advertised to the internet, option B is misleading since private addresses are limited to specific ranges, and option C does not accurately describe the purpose of private addressing.
