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?
- A. Re-IP overlapping address space in the acquired company
- B. Use a single IP address to create a static NAT entry
- C. Use a single IP address to create overload NAT
- D. Build one-to-one NAT translation for every user that needs access
Answer: B
Explanation:
You wouldn't create a NAT to convert every single user from the newly acquired company into one IP address in the other existing company. You would create a static NAT for traffic destined to the server at the network boundary between the 2 companies. Traffic destined to the server from the newly acquired company would be NAT'd to the server IP in Company A.
