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

A company wants to connect its on-premises data center to Google Cloud with a reliable, lower-latency connection that doesn't traverse the public internet, but doesn't need the bandwidth of a full Dedicated Interconnect. Which Google Cloud connectivity product is most appropriate?

⚠ Common exam trap

It's easy for candidates to confuse Partner Interconnect with Cloud VPN, assuming that any private connection must be encrypted or that VPN is sufficient for low-latency needs, but the key differentiator is that Partner Interconnect avoids the public internet entirely, providing consistent latency and SLA-backed reliability that IPsec VPNs cannot guarantee.

Correct answer & explanation

✓

Partner Interconnect, which provides private connectivity through a service provider partner's network — supporting lower bandwidth tiers without requiring a direct physical fiber connection

Partner Interconnect is the correct choice because it provides private connectivity between an on-premises data center and Google Cloud via a service provider partner's network, offering lower bandwidth tiers (e.g., 50 Mbps to 10 Gbps) without requiring a direct physical fiber connection. This meets the requirements for a reliable, lower-latency connection that avoids the public internet, while Dedicated Interconnect would be overkill for bandwidth needs below 10 Gbps.

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, which creates an encrypted IPsec tunnel over the public internet
Why it's wrong here
Cloud VPN establishes an encrypted IPsec tunnel across the public internet, so traffic still traverses ISP routing and shared infrastructure rather than a private path. This fails the stated requirement for connectivity that does not use the public internet, and also introduces public-network latency and availability dependencies. It is designed as a secure overlay, not a private transport service.
✓
Partner Interconnect, which provides private connectivity through a service provider partner's network — supporting lower bandwidth tiers without requiring a direct physical fiber connection
Why this is correct
Partner Interconnect is the right solution. It provides the private connectivity (no public internet) and lower latency characteristics of Dedicated Interconnect, but at lower bandwidth tiers (50 Mbps–50 Gbps) through a service provider partner — appropriate for organizations that don't need or justify a full Dedicated Interconnect circuit.
✗
Dedicated Interconnect, which requires provisioning a 10 Gbps or 100 Gbps dedicated physical fiber connection
Why it's wrong here
Dedicated Interconnect provides the highest performance but requires a direct physical fiber connection at 10 Gbps or 100 Gbps minimum — overkill for a company that doesn't need that bandwidth, and requires colocation at a Google facility or connection point.
✗
Cloud CDN, which caches content at edge locations close to the on-premises data center
Why it's wrong here
Cloud CDN caches content at Google's edge Points of Presence to accelerate delivery to end users, but it is a Layer-7 caching service, not a network interconnect. It does not create or manage any dedicated or private path between an on-premises data center and a Google Cloud VPC. Therefore, it cannot provide the private, low-latency connectivity needed for the organization's hybrid cloud migration.
