A user wants to achieve cross-regional communication between VPCs. Which of the following services can help the user achieve the goal? (Multiple choice)

Question

Options

• APeer-to-peer connection
• BVirtual Private Network
• CCloud Dedicated Line
• DCloud connection

• A
  13% (3)
• B
  78% (18)
• C
  9% (2)

Explanation

Virtual Private Network (B) supports cross-regional VPC communication by creating encrypted tunnels over the public internet between VPCs in different regions, while Cloud Connection (D) is a dedicated service specifically designed to interconnect VPCs across regions through a cloud backbone network, offering higher reliability and performance.

Peer-to-peer connection (A) is incorrect because VPC peering is restricted to the same region; it cannot span across regions in this context. Cloud Dedicated Line (C) is incorrect because it is designed to connect on-premises data centers to the cloud, not to link VPCs in different regions to each other.

Memory tip: Think of scope. Peer-to-peer stays local (same region), Dedicated Line goes physical (on-premises to cloud), but VPN and Cloud Connection both cross regional boundaries within the cloud.
