MD-102 : Endpoint Administrator

As of my last update in 2023, there is no Microsoft certification exam specifically designated as "MD-102." It is possible that there has been a mix-up with the exam numbers or that new exams have been introduced or renumbered since then. However, there is an exam called "MD-100: Windows 10," which is part of the Microsoft Certified: Modern Desktop Administrator Associate certification. Another closely related exam is "MD-101: Managing Modern Desktops," which together with the MD-100, would earn you the Modern Desktop Administrator Associate certification. The MD-101 exam focuses on deploying, configuring, securing, managing, and monitoring devices and client applications in an enterprise environment. Both exams are designed for IT professionals who manage and maintain Windows 10 core services. As for the cost, Microsoft certification exams typically range from $165 USD to $200 USD in the United States, but the prices vary by country and can change over time. If you are asking about another exam or certification that has been introduced after my knowledge cutoff date, I recommend checking the official Microsoft Certification website or contacting Microsoft directly for the most current information.
