Correct Answer

Azure ExpressRoute with a private peering circuit to the on-premises network

Why This Answer Is Correct

Azure ExpressRoute provides private, dedicated connectivity between on-premises networks and Azure over a partner network โ€” without traversing the public internet. For production SAP workloads, ExpressRoute is mandatory (not VPN) due to: (1) consistent, guaranteed bandwidth SLAs, (2) lower latency vs. internet-based VPN, (3) SAP's supportability requirements. VPN Gateway is acceptable for non-production or smaller workloads but has lower bandwidth limits and internet-path variability. Both can coexist for redundancy (ExpressRoute + VPN failover).
