I’m currently on my journey to prepare for the ServiceNow CTA exam and have been exploring multiple study resources, including whitepapers, documentation, and hands-on practice in my instance. Recently, I started using CertsMatrix to practice scenario-based questions, which has been really helpful in understanding architectural best practices and decision-making under real-world constraints. One scenario I’m working through: In a large, multi-instance environment with heavy integrations, how would you design a solution that ensures scalability, security, and maintainability without impacting performance? Should I prioritize cloning instances, creating scoped applications, or implementing a custom integration framework? I’d love to hear from certified CTAs or anyone who has handled similar enterprise-level designs. Insights on how you approached such decisions in practice would be incredibly valuable as I continue preparing.
