- A
Configure Cloud Armor with IP allowlist
Why wrong: Cloud Armor protects HTTP(S) load-balanced applications, not Cloud Storage buckets.
- B
Enable VPC Service Controls
Why wrong: VPC Service Controls provide context-based access (e.g., VPC network) but not IP-based conditions.
- C
Set a bucket policy with an IP address condition
Using IAM conditions, you can restrict access to requests originating from the corporate IP range.
- D
Configure Cloud NAT
Why wrong: Cloud NAT provides outbound internet to private instances, not access control.
- E
Use Cloud KMS to create and manage a key for CMEK
Customer-managed encryption keys (CMEK) for Cloud Storage are managed through Cloud KMS.

Cloud Digital Leader Google Cloud Products and Services Practice Question
This GCDL practice question tests your understanding of google cloud products and services. 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 stores sensitive data in Cloud Storage. They want to restrict access to only users from the company's corporate network (IP range 203.0.113.0/24) and ensure data is encrypted at rest using a customer-managed key. Which TWO configurations are required? (Select 2)

Correct answer & explanation
✓
Set a bucket policy with an IP address condition
Cloud Storage bucket-level access control with IP-based conditions can restrict access to a specific IP range. CMEK requires Cloud KMS to create and manage the key. Cloud Armor is for HTTP(S) load balancing, not Cloud Storage. VPC Service Controls provide perimeter security but are not IP-based. 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.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure Cloud Armor with IP allowlist
Why it's wrong here
Cloud Armor protects HTTP(S) load-balanced applications, not Cloud Storage buckets.
- ✗

Why this is correct
Customer-managed encryption keys (CMEK) for Cloud Storage are managed through Cloud KMS.
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 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.
