- A
Cloud VPN
Why wrong: Cloud VPN is a software-defined VPN over the internet; it does not provide dedicated bandwidth or the same low latency.
- B
Cloud CDN
Why wrong: Cloud CDN is for content caching and delivery, not for hybrid cloud connectivity.
- C
Cloud NAT
Why wrong: Cloud NAT provides outbound internet access to private instances, not hybrid cloud connectivity.
- D
Cloud Interconnect
Cloud Interconnect provides dedicated, high-bandwidth, low-latency connections between on-premises networks and Google Cloud.

Cloud Digital Leader Google Cloud Products and Services Practice Question
This GCDL practice question tests your understanding of google cloud products and services. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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?
Answer choices
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 dedicated physical connections between on-premises and Google Cloud. HA VPN is a low-cost alternative but uses the public internet and offers lower bandwidth. Cloud CDN is for content delivery. Cloud NAT is for outbound connectivity.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
