Cloud Digital Leader Google Cloud Products and Services Practice Question
A company wants to set up a hybrid cloud connection between its on-premises data center and Google Cloud VPC with a dedicated, high-bandwidth, low-latency link. Which service should they use?
⚠ Common exam trap
GCDL often tests the misconception that Cloud VPN can provide dedicated, high-bandwidth, low-latency connectivity, but it actually uses the public internet and is not dedicated; candidates must distinguish between VPN (encrypted tunnel over internet) and Interconnect (private dedicated link).

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
✓
Cloud Interconnect
Cloud Interconnect provides a dedicated, private physical connection between an on-premises network and a Google Cloud VPC, offering high bandwidth (10 Gbps or 100 Gbps per link) and low latency compared to public internet paths. It supports Dedicated Interconnect (direct connection at a Google colocation facility) and Partner Interconnect (via a service provider), both designed for enterprise-grade hybrid cloud connectivity. This meets the requirement for a dedicated, high-bandwidth, low-latency link.
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
Why it's wrong here
Cloud VPN establishes encrypted IPSec tunnels over the public internet, so traffic shares the internet's best-effort routing and experiences unpredictable latency and variable throughput. Because it lacks dedicated bandwidth or a private path, it cannot meet strict performance or reliability requirements for a hybrid cloud connection, though it is useful for low-cost, low-throughput backup or testing.
- ✗
Cloud CDN
Why it's wrong here
Cloud CDN is a global content delivery network that caches static and dynamic content at edge locations to accelerate delivery to end users, not to connect corporate networks. It does not create any routed path or tunnel between an on-premises environment and Google Cloud, so it is irrelevant to hybrid cloud infrastructure.
- ✗
Cloud NAT
Why it's wrong here
Cloud NAT enables private Compute Engine instances to initiate outbound internet connections while remaining unreachable from the internet, but it does not terminate any inbound connections or create a cross-premises link. It is an egress-only gateway service, so it cannot serve as a bidirectional hybrid connectivity option.
- ✓
Cloud Interconnect
Why this is correct
Cloud Interconnect provides direct, dedicated network connections between your on-premises network and Google Cloud, either via co-location facilities (Dedicated Interconnect) or through a service provider (Partner Interconnect). These private links offer consistent high bandwidth, low latency, and a guaranteed SLA, making them the correct choice for a hybrid cloud connection.
