A cybersecurity team is tasked with deploying a stringent zero-trust network access policy across a newly segmented IoT environment. During the pilot phase, it becomes evident that the policy\'s enforcement mechanisms are causing widespread authentication failures with critical legacy devices that rely on outdated, but still essential, authentication protocols. The original implementation plan has hit a significant roadblock, requiring a swift recalibration of the approach to avoid disrupting operations and to meet regulatory compliance deadlines. Which strategic adjustment best exemplifies the required adaptability and problem-solving under these circumstances?
