Correct answer & explanation
✓
Cloud Interconnect
Cloud Interconnect provides dedicated, high-bandwidth connections between on-premises and Google Cloud, offering lower latency and more reliability than VPN.
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 Interconnect
Why this is correct
Cloud Interconnect provides direct, private connectivity between your on-premises network and Google Cloud through either Dedicated Interconnect (a physical cross-connect at a colocation facility) or Partner Interconnect (via a service provider). This bypasses the public internet, offering lower latency, higher bandwidth, and more consistent performance. It also delivers a Google Cloud SLA, making it the correct choice for production-grade hybrid connectivity.
- ✗
Cloud NAT
Why it's wrong here
Cloud NAT is a managed network address translation service that enables outbound internet connections from VM instances that have no external IP addresses. It does not provide any inbound or bidirectional private path, and it cannot connect your on-premises data center to Google Cloud as a dedicated link. It is purely for egress internet access from within a VPC, not for hybrid connectivity.
- ✗
Cloud VPN
Why it's wrong here
Cloud VPN creates an IPsec tunnel over the public internet, so traffic is encrypted but still traverses shared, best-effort infrastructure. This introduces encryption/decryption overhead, variable latency, and limited throughput, making it unsuitable for low-latency, high-bandwidth private connectivity. It can be a fallback or for temporary connections, but not the answer for a dedicated low-latency link.
- ✗
Cloud CDN
Why it's wrong here
Cloud CDN is a content delivery network that caches static and dynamic content at Google's edge PoPs to accelerate web delivery to end users. It operates at the HTTP(S) layer and does not create any private network path between your data center and Google Cloud. It cannot carry arbitrary IP traffic or serve as a private connectivity option for hybrid cloud workloads.
