Designing Cisco Enterprise Networks (ENSLD) — Question 60
Company A recently acquired another company. Users of the newly acquired company must be able to access a server that exists on Company A's network, both companies use overlapping IP address ranges. Which action conserves IP address space and provides access to the server?
Answer options
- A. Use a single IP address to create overload NAT
- B. Use a single IP address to create a static NAT entry
- C. Build one-to-one NAT translation for every user that needs access
- D. Re-IP overlapping address space in the acquired company
Correct answer: A
Explanation
The correct answer is A because using overload NAT allows multiple users to share a single public IP address, conserving IP address space while providing necessary access. In contrast, options B and C do not address the overlapping issue efficiently and would require more IP addresses, while option D would involve significant changes to the acquired company's network configuration.
