Zorluk: ZorAzure Virtual Networks, ExpressRoute, and VPN Gateway

A company is establishing connectivity between its on-premises headquarters and an Azure Virtual Network. The connection must bypass the public internet to ensure predictable performance and security. Additionally, the company's internal compliance policy mandates that all data in transit must be encrypted at the network layer using IPsec. Which solution satisfies all of these requirements?

  1. A Site-to-Site VPN gateway connection configured over an Azure ExpressRoute private peering connectionCevap
  2. B
    An Azure ExpressRoute connection configured with Microsoft peering to encrypt traffic using native IPsec over the public internet
  3. C
    A standard Site-to-Site VPN gateway connection using a public IP address over the public internet
  4. D
    An Azure Virtual Network peering connection configured with a public VPN Gateway transit

Cevap

A Site-to-Site VPN gateway connection configured over an Azure ExpressRoute private peering connection
The correct option is the Site-to-Site VPN gateway connection configured over an Azure ExpressRoute private peering connection. ExpressRoute provides a dedicated, private connection that does not traverse the public internet, ensuring predictable performance. Since ExpressRoute does not natively encrypt traffic, configuring a VPN tunnel over the private peering allows the traffic to be encrypted using IPsec, meeting both constraints.

Adım Adım Çözüm

1
Analyze the connectivity requirements.
The solution requires bypassing the public internet (satisfied by Azure ExpressRoute) and encrypting traffic at the network layer using IPsec (satisfied by VPN Gateway).
This establishes the dual constraints of private dedicated routing and cryptographic encryption.
2
Evaluate the combined capability of VPN and ExpressRoute.
A Site-to-Site VPN can be configured to run over an ExpressRoute private peering circuit, creating an encrypted tunnel over a private connection.
This specific hybrid architecture satisfies both security and performance constraints.
