Google ACE Practice Question: An enterprise requires a private connection…
An enterprise requires a private connection between its on-premises data center and Google Cloud VPC that does NOT traverse the public internet and provides dedicated 10 Gbps bandwidth. Which connectivity option meets these requirements?
⚠ Common exam trap
A common mix-up: candidates confuse Partner Interconnect with Dedicated Interconnect, assuming both offer dedicated bandwidth, but Partner Interconnect relies on a third-party provider's network and may not guarantee the same level of isolation or dedicated 10 Gbps per circuit.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Dedicated Interconnect
Dedicated Interconnect provides a direct, private physical connection between your on-premises network and Google Cloud VPC, offering bandwidth up to 10 Gbps per circuit (or 100 Gbps with multiple circuits) without traversing the public internet. This meets the requirement for a private connection with dedicated 10 Gbps bandwidth, as it uses a colocation facility and a Google-supported router.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Cloud VPN with high-availability configuration
Why it's wrong here
Cloud VPN with high-availability configuration creates two encrypted IPsec tunnels between your on-premises VPN gateway and two different Google Cloud VPN gateways. It delivers a 99.99% availability SLA and automatically fails over if one tunnel drops, but the tunnels run over the public internet. Because traffic is still subject to internet routing, latency, packet loss, and bandwidth are not guaranteed, so it cannot provide a dedicated, private physical path with consistent performance. This makes it a good disaster-recovery option, not a substitute for a direct connection.
- ✗
Partner Interconnect
Why it's wrong here
Partner Interconnect provides a private connection between your data center and Google's edge network, but it relies on a service provider (telecommunications carrier) that already has a presence in a Google Cloud region. The physical circuit terminates at the partner's facility, not directly at a Google colocation point, and the partner then extends connectivity to Google. This means it is not a direct, dedicated physical cable from your data center to Google's network, so it does not meet the requirement for a fully direct physical connection.
- ✓
Dedicated Interconnect
Why this is correct
Dedicated Interconnect is the only option that provides a direct physical connection from your enterprise data center to Google's network. You must contract with a colocation provider like Equinix or Digital Realty, and Google installs a cross-connect in that facility to your router. It is available in 10 Gbps or 100 Gbps increments, offers a 99.99% uptime SLA, and allows you to access private VPC resources (e.g., Compute Engine instances) without traversing the public internet, making it ideal for high-throughput, low-latency hybrid workloads.
- ✗
Direct Peering
Why it's wrong here
Direct Peering is a BGP peering session between your router and Google's edge at one of Google's point-of-presence (PoP) locations. It only exchanges routes for Google's public IP addresses, such as Google Workspace, YouTube, and the public APIs of Google Cloud—it does not provide access to private VPC IP addresses or internal load balancers. Since it is not a dedicated private path and cannot reach your VPC's private range, it is unsuitable for connecting to private resources in your VPC without additional mechanisms like Cloud VPN or Interconnect.

VPC
A Virtual Private Cloud (VPC) is a logically isolated section of a cloud provider's network where you can launch and manage resources like servers and databases with complete control over IP addressing, subnets, route tables, and security.
Key term
Router
A router is a networking device that connects different networks together and directs data traffic between them by choosing the best path for data to travel.
