CCNA: Cisco Certified Network Associate — Question 82

Which function does the range of private IPv4 addresses perform?

Answer options

• A. allows multiple companies to each use the same addresses without conflicts
• B. provides a direct connection for hosts from outside of the enterprise network
• C. ensures that NAT is not required to reach the Internet with private range addressing
• D. enables secure communications to the Internet for all external hosts

Correct answer: A

Explanation

The correct answer, A, indicates that private IPv4 addresses can be reused by different organizations without causing address conflicts. Options B, C, and D are incorrect because private addresses are not directly reachable from the Internet, require NAT for Internet access, and do not inherently provide secure communications for external hosts.
