Why This Question Matters

This easy-level SQL question appears frequently in data engineering interviews at companies like Virtusa. While less common, it tests deeper understanding that distinguishes strong candidates. Mastering the underlying concepts (sql) will help you answer variations of this question confidently.

How to Approach This

Start by clearly defining the core concept being asked about. Interviewers want to see that you understand the fundamentals before diving into implementation details. Structure your answer with a definition, then explain the practical application with a concise example.

Without SHIR: (1) VPN/ExpressRoute: Connect cloud to on-prem network; use private SQL Server IP from cloud. (2) Public endpoint: Not recommended—security risk. (3) Export/Load: SSIS or script exports to blob; cloud job loads. (4) Third-party: Fivetran, Striim with on-prem agent. (5) Reverse proxy: On-prem proxy exposes limited endpoint. Trade-off: VPN adds latency; export is batch-only. Security: Prefer private connectivity.
