- A
Cloud Functions (2nd gen) with VPC connector
2nd gen supports VPC connectors and can run inside a VPC.
- B
Cloud Functions (1st gen) with VPC connector
Why wrong: 1st gen does not support VPC connectors for egress to VPC; it only supports serverless VPC access for outbound.
- C
Cloud Functions (2nd gen) with Cloud VPN
Why wrong: Cloud VPN is for hybrid connectivity, not for attaching a function to a VPC.
- D
Cloud Functions (1st gen) with Cloud NAT
Why wrong: Cloud NAT is for outbound internet, not for VPC connectivity.

Google ACE Planning and Configuring a Cloud Solution Practice Question
This ACE practice question tests your understanding of planning and configuring a cloud solution. 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 use Cloud Functions to process events from Cloud Storage when new objects are uploaded. They need the function to run in a specific VPC network for tight security. Which Cloud Functions generation supports VPC connectivity?
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 Functions (2nd gen) with VPC connector
Cloud Functions (2nd gen) is built on Cloud Run and supports VPC connectivity via connectors or direct VPC. 1st gen does not support VPC connectors for ingress/egress in the same way. 2nd gen is recommended for VPC network integration.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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 Functions (2nd gen) with VPC connector
Why this is correct
2nd gen supports VPC connectors and can run inside a VPC.
Related concept
Static NAT maps one inside address to one outside address.
- ✗
Cloud Functions (1st gen) with VPC connector
Why it's wrong here
1st gen does not support VPC connectors for egress to VPC; it only supports serverless VPC access for outbound.
- ✗
Cloud Functions (2nd gen) with Cloud VPN
Why it's wrong here
Cloud VPN is for hybrid connectivity, not for attaching a function to a VPC.
- ✗
Cloud Functions (1st gen) with Cloud NAT
Why it's wrong here
Cloud NAT is for outbound internet, not for VPC connectivity.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.

Cloud Service Model Comparison
| Model | You Manage | Provider Manages | Examples |
|---|---|---|---|
| IaaS | OS, runtime, apps, data | Hardware, hypervisor, networking | EC2, Azure VMs, GCP Compute Engine |
| PaaS | Apps and data | OS, runtime, middleware, hardware | Elastic Beanstalk, Azure App Service |
| SaaS | Data and settings only | Everything else | Microsoft 365, Salesforce, Workday |
| FaaS / Serverless | Function code only | Infra, scaling, runtime | Lambda, Azure Functions, Cloud Run |
| CaaS | Containers and apps | Kubernetes, OS, hardware | EKS, AKS, GKE |
