You are designing a distributed application for Azure.
The application must securely integrate with on-premises servers.
You need to recommend a method of enabling Internet Protocol security (IPsec)-protected connections between on-premises servers and the distributed application.
What should you recommend?
A . Azure Access Control
B . Azure Content Delivery Network (CDN)
C . Azure Service Bus
D . Azure Site-to-Site VPN
IPsec can be used on Azure Site-to-Site VPN connections. Distributed applications can used the IPSec VPN connections to communicate.
