CCNA: Cisco Certified Network Associate — Question 465

What are two reasons to deploy private addressing on a network? (Choose two.)

Answer options

• A. to subnet addresses in an organized hierarchy
• B. to reduce network maintenance costs
• C. to segment local IP addresses from the global routing table
• D. to hide sensitive data from access users within an enterprise
• E. to route protected data securely via an Internet service provider

Correct answer: B, C

Explanation

Choosing option B is correct because private addressing can lead to lower network maintenance costs by minimizing the need for public IP addresses. Option C is also correct as private addresses are not routed on the global Internet, effectively segmenting them from the global routing table. The other options either do not directly relate to private addressing or are not accurate in the context of its primary purposes.
