Microsoft Azure Fundamentals AZ-900 Practice Exam 2025 – Complete Study Resource

The choice that focuses on improving application performance is indeed correct. Azure Advisor provides recommendations that can help optimize application performance by identifying opportunities such as adjusting resource configurations and scaling, which can lead to faster processing times and better response rates. By following these recommendations, businesses can ensure that their applications run more efficiently and can handle increased loads without degradation in performance.

The other options, while important aspects of Azure services, do not directly address application performance. Detecting security vulnerabilities pertains to the security posture of an application, ensuring that it is protected against threats. Ensuring fault tolerance relates to maintaining application availability and reliability even in the face of failures. Notifying for updates is crucial for keeping systems up-to-date, but it does not specifically enhance application speed or performance. Hence, focusing on the aspect that directly speeds up applications aligns best with the question.
