An administrator is tasked with configuring connectivity between an on-premises datacenter and Azure.

For configuring connectivity between an on-premises datacenter and Azure, the two supported options are:

VPN (Virtual Private Network):Site-to-Site VPN allows you to create a secure connection from your on-premises network to Azure over the public internet using IPsec/IKE protocols.

ExpressRoute:Provides a private connection between your on-premises infrastructure and Azure, ensuring traffic does not traverse the public internet.

Both options provide secure and reliable connectivity, with ExpressRoute offering enhanced performance and security due to its private connection.References
