Cloud Digital Leader Practice Question: Google Cloud products, services, and solutions

A multinational corporation needs to establish a private, low-latency connection between their on-premises data center and Google Cloud. The connection must be consistent, reliable, and support at least 10 Gbps throughput. Which solution should they use?

⚠ Common exam trap

Google Cloud often tests the distinction between Dedicated and Partner Interconnect, where candidates mistakenly choose Partner Interconnect for higher throughput, but Dedicated Interconnect is the only option that provides direct, private physical links at 10 Gbps or 100 Gbps without a service provider intermediary.

Correct answer & explanation

✓

Dedicated Interconnect

Dedicated Interconnect provides a direct, private physical connection between an on-premises network and Google Cloud, offering consistent, reliable, low-latency connectivity with throughput options of 10 Gbps or 100 Gbps per link. This meets the requirement for a private, low-latency connection with at least 10 Gbps throughput, as it bypasses the public internet entirely and provides a Service Level Agreement (SLA) for uptime and performance.

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 NAT with static IP addresses
Why it's wrong here
Cloud NAT with static IP addresses is a managed network address translation service that enables instances in a VPC to initiate outbound connections to the internet while preserving a consistent source IP. It does not provide any inbound private connectivity from an on-premises environment to GCP, nor does it establish a dedicated, low-latency path between networks. Static IPs merely stabilize the egress address; they do not create a private circuit, which fails the core requirement of a private, high-throughput connection.
✓
Dedicated Interconnect
Why this is correct
Dedicated Interconnect is the correct choice because it establishes one or more direct, physical connections between your on-premises network and Google's edge network using colocation facilities. These private links offer high throughput (10 Gbps or 100 Gbps per connection) and low, consistent latency because traffic does not traverse the public internet. It is ideal for latency-sensitive, bandwidth-heavy workloads that demand a private, reliable, and dedicated network path between a multinational corporation and GCP.
✗
Partner Interconnect via a service provider
Why it's wrong here
Partner Interconnect via a service provider is a private connection option that uses a third-party network provider to reach Google, making it useful when a dedicated colocation facility is unavailable or when smaller bandwidth increments (e.g., 50 Mbps to 50 Gbps) are sufficient. However, it introduces an intermediary provider, which can add variable latency and less direct control compared to Dedicated Interconnect. Since Dedicated Interconnect is already a viable option for this multinational corporation, Partner Interconnect is a secondary—not optimal—choice.
✗
Cloud VPN using IPsec tunnels over the public internet
Why it's wrong here
Cloud VPN using IPsec tunnels encrypts and routes traffic over the public internet, so although it provides a secure connection, it does not offer the private, dedicated, or consistent low-latency path required here. Internet routing and congestion cause unpredictable latency and throughput, and VPN throughput is typically lower than that of a dedicated interconnect, especially over long distances. For a multinational corporation needing low latency and high throughput for private workloads, Cloud VPN is not an appropriate replacement for a dedicated private connection.
