CCNA: Cisco Certified Network Associate — Question 115

Which two goals reasons to implement private IPv4 addressing on your network? (Choose two.)

Answer options

• A. Comply with PCI regulations
• B. Conserve IPv4 address
• C. Reduce the size of the forwarding table on network routers
• D. Reduce the risk of a network security breach
• E. Comply with local law

Correct answer: B, D

Explanation

Choosing private IPv4 addressing helps conserve the limited number of available IPv4 addresses, which is essential given the scarcity of public IPs. Additionally, using private addresses can enhance security by isolating internal networks from external threats, thus reducing the risk of security breaches. The other options, while relevant to network management, do not directly relate to the primary benefits of implementing private IPv4 addressing.
