Correct Answer: A. Create 200 new hosted zones in the Amazon Route 53 console. Import zone files

Explanation

To maximize availability and minimize operational overhead, a solutions architect should recommend creating 200 new hosted zones in the Amazon Route 53 console and importing the zone files. Amazon Route 53 is a highly available and scalable DNS service provided by AWS. By creating new hosted zones, the company can migrate their DNS servers to AWS and take advantage of the availability and scalability offered by Route 53. Importing the zone files allows for a seamless transition of the existing DNS configurations to the new hosted zones. This solution eliminates the need for managing and maintaining the DNS servers, reducing operational overhead.
