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. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 is migrating its on-premises applications to Google Cloud. The security team requires that all data be encrypted both in transit and at rest. Which approach meets these requirements with minimal operational overhead?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use HTTPS for all traffic and enable default encryption at rest with Google-managed keys.
Option A is correct because HTTPS provides encryption in transit using TLS, and default encryption at rest with Google-managed keys encrypts data stored in Google Cloud services like Cloud Storage and Compute Engine disks without requiring any manual key management. This approach meets the security requirements with minimal operational overhead since Google handles key rotation and lifecycle management automatically.
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.
✓
Use HTTPS for all traffic and enable default encryption at rest with Google-managed keys.
Why this is correct
Google Cloud encrypts data at rest by default; HTTPS provides encryption in transit.
Related concept
Read the scenario before looking for a memorised answer.
✗
Implement a third-party encryption tool for both transit and at rest.
Why it's wrong here
Third-party tools add unnecessary complexity; built-in options are sufficient and simpler.
✗
Set up a VPN between on-premises and Google Cloud and rely on that for encryption.
Why it's wrong here
VPN encrypts network traffic but does not cover encryption at rest or application-level traffic.
✗
Restrict physical access to Google Cloud data centers.
Why it's wrong here
Physical security does not encrypt data.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the misconception that a VPN alone satisfies both encryption in transit and at rest requirements, but candidates must remember that VPNs only cover transit encryption and do not address data at rest within the cloud provider's infrastructure.
Detailed technical explanation
How to think about this question
Google Cloud uses AES-256 for encryption at rest by default, with keys managed by Google Cloud Key Management Service (Cloud KMS) for customer-managed encryption keys (CMEK) or Google-managed keys for minimal overhead. HTTPS uses TLS 1.2 or 1.3 to encrypt data in transit, ensuring confidentiality and integrity between clients and Google Cloud endpoints. In a real-world scenario, a company migrating legacy applications might need to ensure that all API calls and data transfers use HTTPS, while storage buckets and persistent disks automatically benefit from default encryption at rest without any code changes.
KKey Concepts to Remember

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.
