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.
An organization with multiple teams needs to provision separate, isolated environments (e.g., development, test, production) while sharing common services like Cloud NAT and VPC firewall rules. Which VPC networking pattern is most suitable?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Shared VPC (XPN)
Shared VPC (XPN) allows an organization to create a single, centrally managed VPC network that hosts common services like Cloud NAT and firewall rules, while enabling multiple project teams to provision their own isolated environments (dev, test, prod) within that same VPC. This pattern meets the requirement for separate, isolated environments with shared services without needing individual VPCs for each team.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Network Service Tiers (Premium vs Standard)
Why it's wrong here
These tiers affect network performance and egress pricing, not isolation or resource sharing.
✓
Shared VPC (XPN)
Why this is correct
Shared VPC allows central network administration and isolated service projects with shared resources.

✗
VPC Network Peering between team VPCs
Why it's wrong here
Peering connects separate VPCs but requires individual management and does not easily share NAT or firewall rules centrally.
✗
Single VPC with per-team firewall rules
Why it's wrong here
Firewall rules can isolate traffic but all teams share the same VPC; not full project-level isolation.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse VPC Network Peering with Shared VPC, thinking peering provides shared services, but peering only connects networks without allowing shared NAT or centralized firewall rules.
Detailed technical explanation
How to think about this question
Shared VPC uses a host project to define the VPC network, including subnets, Cloud NAT, and firewall rules, while service projects attach to that host project and can use its subnets. This allows each team to deploy resources in their own service project with isolated subnet ranges, yet all traffic can egress through a single Cloud NAT instance, and common firewall rules apply across all environments. A real-world scenario is a multi-tenant SaaS platform where dev, test, and prod environments must share a NAT gateway for outbound internet access but remain in separate projects for IAM and cost tracking.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
