- A
Yes, customers must enable encryption in the Cloud Storage bucket settings for each bucket.
Why wrong: Encryption is automatic and requires no configuration. There is no 'enable encryption' setting in Cloud Storage — all data is encrypted by default.
- B
No, Google Cloud encrypts all data at rest automatically using AES-256 — no configuration is needed.
All Google Cloud storage services encrypt data at rest by default with AES-256. Customers receive encryption without any setup, and can optionally use CMEK for key management control.
- C
Only data in premium storage tiers is encrypted; Standard storage requires manual encryption.
Why wrong: Encryption is applied to all storage tiers equally — Standard, Nearline, Coldline, and Archive are all encrypted by default.
- D
Customers must purchase the Security Command Center Premium tier to enable data encryption.
Why wrong: Security Command Center is a security monitoring service; it doesn't control data encryption. Encryption is automatic and included in the base service at no additional charge.
Quick Answer
The answer is no, you do not need to do anything special to encrypt data stored in Cloud Storage because Google Cloud automatically encrypts all customer data at rest using AES-256 without any configuration required. This default encryption at rest is applied transparently to every Cloud Storage bucket, regardless of storage class or region, using Google-managed keys unless you opt for Customer-Managed Encryption Keys (CMEK) or Customer-Supplied Encryption Keys (CSEK). On the Google Cloud Digital Leader exam, this concept tests your understanding of Google Cloud’s shared responsibility model and its built-in security posture, often appearing as a straightforward true/false or multiple-choice question where the trap is assuming encryption requires manual setup. A common memory tip is to remember “AES-256 by default” — think of it as Google Cloud’s automatic security blanket for all data at rest, so you never have to flip a switch for basic protection.
Cloud Digital Leader Trust and security with Google Cloud Practice Question
This GCDL practice question tests your understanding of trust and security with google cloud. 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.
Google Cloud encrypts all customer data at rest by default without any configuration required. A customer asks: 'Do we need to do anything special to encrypt our data stored in Cloud Storage?' What is the correct answer?
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
No, Google Cloud encrypts all data at rest automatically using AES-256 — no configuration is needed.
Option B is correct because Google Cloud automatically encrypts all customer data at rest using AES-256 encryption, with no configuration required. This default encryption applies to all Cloud Storage buckets, regardless of storage class or region, and the encryption keys are managed by Google Cloud unless the customer chooses to use Customer-Managed Encryption Keys (CMEK) or Customer-Supplied Encryption Keys (CSEK).
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
The trap here is that candidates may assume encryption requires explicit action (like enabling a setting or purchasing an add-on) because many cloud providers or on-premises systems require manual configuration, but Google Cloud encrypts all data at rest by default with no customer effort.

Detailed technical explanation
How to think about this question
Under the hood, Google Cloud uses AES-256 encryption with keys managed by the Cloud Key Management Service (Cloud KMS) for default encryption, and the encryption is applied at the storage device level before data is written to disk. A subtle behavior is that even if a customer uses CMEK or CSEK, the default encryption still applies as a baseline, and the custom key is used for an additional encryption layer. In a real-world scenario, a customer migrating sensitive data must understand that default encryption is always active, but compliance requirements may still necessitate CMEK for auditability and key rotation control.
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.
