- A
Enable Private Google Access on the VPC subnet.
Why wrong: Private Google Access allows VMs to reach Google APIs via private IP, but does not restrict access from public internet.
- B
Use Cloud Storage signed URLs for all access.
Why wrong: Signed URLs provide temporary access but do not restrict network origin.
- C
Disable public internet access by turning off the default internet gateway.
Why wrong: This would break all internet access, not just to Cloud Storage.
- D
Use IAM conditions to restrict access based on VPC network.
IAM conditions can restrict access to requests originating from a specific VPC network.
- E
Use VPC Service Controls to create a service perimeter around Cloud Storage.
VPC Service Controls prevent data exfiltration and restrict access to allowed networks.
PDE Storing the Data Practice Question
This PDE practice question tests your understanding of storing the data. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 uses Cloud Storage to store sensitive customer data. They need to restrict access to the data so that only requests from within a specific VPC network are allowed, and block all access from the public internet. Which TWO configurations should they implement? (Choose 2.)
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
Use IAM conditions to restrict access based on VPC network.
Option D is correct because IAM conditions can be used to restrict access to Cloud Storage based on the requester's VPC network, ensuring only requests originating from the specified VPC are allowed. Option E is correct because VPC Service Controls create a service perimeter that prevents data exfiltration and blocks access from outside the perimeter, effectively denying public internet requests.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that disabling the internet gateway or using Private Google Access alone can block public access to Cloud Storage, when in fact these controls affect connectivity from within the VPC, not inbound requests to Google-managed services.
Detailed technical explanation
How to think about this question
VPC Service Controls enforce a service perimeter using context-aware access policies that evaluate the source VPC network and IP address, effectively creating a virtual boundary around Cloud Storage. IAM conditions leverage the `gcp.compute.vpc` attribute to match requests to a specific VPC network name, which is evaluated at the IAM policy level before any bucket policy. This dual-layer approach ensures that even if a bucket is publicly accessible, requests from outside the perimeter are denied at the IAM or perimeter boundary.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
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.
