A data analytics company needs to provide secure, high-performance network access for its analysts to access data stored in Google Cloud. The analysts are located in an on-premises data center and require direct connectivity to Google Cloud, bypassing the public internet, to ensure data privacy and compliance. They need consistent, high-bandwidth access for transferring large datasets. Which Google Cloud networking solution should be recommended?

  1. ADirect Peering
  2. BCloud VPN (IPsec VPN)
  3. CCloud Interconnect (Dedicated Interconnect)
  4. DCloud Interconnect (Partner Interconnect)
Show answer & explanation

Correct answer: C. Cloud Interconnect (Dedicated Interconnect)

Dedicated Interconnect provides a direct, physical connection between the customer's on-premises network and Google's network, offering the highest bandwidth, lowest latency, and bypassing the public internet, which is ideal for large datasets, high performance, and strict data privacy/compliance.

Why the other options are wrong

  • A. Direct Peering is typically used for exchanging traffic between Google's network and a peer's network, often for larger network providers, and doesn't provide a direct, private connection for a single enterprise's on-premises network to its Google Cloud VPC.
  • B. Cloud VPN uses encrypted tunnels over the public internet, which does not bypass the internet and typically has lower bandwidth and higher latency than dedicated solutions.
  • D. Partner Interconnect uses a service provider to connect to Google's network. While it bypasses the public internet, Dedicated Interconnect offers a direct physical connection, often with higher bandwidth options and more direct control, making it superior for 'highest performance' and 'consistent, high-bandwidth'.

Dedicated Interconnect

A physical, direct connection between your on-premises data center and Google's network, offering private, high-bandwidth, and low-latency connectivity, bypassing the public internet.

  • Physical direct connection
  • Highest bandwidth and lowest latency
  • Bypasses public internet for increased security and performance

Memory trick: Dedicated Interconnect is your private express lane to Google Cloud.
