Infrastructure and Systems Architecture Questions

Comprehensive knowledge of enterprise infrastructure and systems architecture principles, trade offs, and design patterns. Candidates should be able to compare on premises versus cloud deployments and describe hybrid cloud models, virtualization and container strategies, compute and storage choices, and networking fundamentals including segmentation and connectivity. Topics include high availability and redundancy approaches, disaster recovery and business continuity planning, capacity and performance planning, systems integration and messaging patterns, and how infrastructure decisions affect security, compliance, cost, and operational complexity. Be prepared to discuss automation, infrastructure as code, monitoring and observability, and the rationale behind architecture choices for scalability and resilience.
