CCNA Routing and Switching (legacy) — Question 144

What are two benefits of private IPv4 IP addresses? (Choose two.)

Answer options

• A. They are routed to the Internet the same as public IP addresses.
• B. They are less costly than public IP addresses.
• C. They can be assigned to devices without Internet connections.
• D. They eliminate the necessity for NAT policies.
• E. They eliminate duplicate IP conflicts.

Correct answer: B, C

Explanation

The correct answers are B and C because private IPv4 addresses are indeed less expensive to use than public ones and can be assigned to devices that don't access the Internet. Option A is incorrect because private IP addresses are not routed on the Internet, D is wrong as NAT is still necessary for Internet connectivity, and E is false since duplicate IP conflicts can still occur within a private network.
