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 has multiple Google Cloud projects and needs to connect VPCs in different regions privately without traversing the public internet or using VPN tunnels. Which two Google Cloud networking solutions can accomplish this requirement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
VPC Peering
Options A and C are correct. VPC Peering (A) allows direct peering between VPCs across regions without internet. Shared VPC (C) allows centralized management and connectivity between host and service projects. Option B (Cloud NAT) is for outbound internet access. Option D (Cloud VPN) uses the public internet. Option E (Private Google Access) allows on-premises access to Google APIs.
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.
✓
VPC Peering
Why this is correct
Direct private connectivity between VPC networks, supports cross-region peering.
Related concept
Static NAT maps one inside address to one outside address.
✗
Private Google Access
Why it's wrong here
Provides on-premises access to Google APIs without public IP, but does not connect VPCs.
✗
Cloud NAT
Why it's wrong here
Provides outbound internet connectivity for instances with no public IPs.
✗
Cloud VPN
Why it's wrong here
Uses the public internet to connect networks, not private.
✓
Shared VPC
Why this is correct
Allows multiple projects to share a common VPC network, enabling private connectivity.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
