The answer is A, or To be able to maintain servers remotely. Why? Well, a business would not want to allow outside customers access to files because that’s a blatant red flag. There would be no reason to completely eliminate physical servers because there simply isn’t a reason to. They would not want to secure the company intranet because if they did, their solution would not be to use virtual machines surely.
Your final answer: To be able to maintain servers remotely. It’s slightly more efficient, and it makes sense for the company to be accomplishing this goal by using virtual machines.
