CCNA: Cisco Certified Network Associate — Question 1090

What is a characteristic of private IPv4 addressing?

Answer options

• A. enables secure connectivity over the internet
• B. complies with PCI regulations
• C. provides an added level of protection against internet threats
• D. is used on internal hosts that stream data solely to external resources

Correct answer: C

Explanation

The correct answer, C, is accurate because private IPv4 addresses are not routable on the public internet, providing an additional layer of security. Options A and D are incorrect because private addresses do not enable secure internet connectivity or are exclusively for external data streaming. Option B is misleading as PCI regulations pertain to secure payment data management, not specifically to private addressing.
