GCDL Practice Question: A security architect is evaluating Google Cloud's…
This GCDL practice question tests your understanding of a security architect is evaluating google cloud's…. 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 security architect is evaluating Google Cloud's approach to securing customer data against both external attackers and potential internal Google personnel access. She identifies four distinct controls: (1) encryption at rest by default, (2) Access Transparency logs, (3) Customer-Managed Encryption Keys (CMEK), and (4) Access Approval. How do these four controls work together to provide layered data protection?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
These controls are only relevant for government or military workloads; commercial enterprises don't need this level of protection
While government and regulated industries often require these controls, they are available to and used by commercial enterprises. Healthcare, financial services, and any organization with sensitive data benefits from these controls.
B
Distractor review
CMEK alone provides complete data protection — the other three controls are unnecessary if customer-managed keys are in use
CMEK provides cryptographic control but doesn't provide visibility (Access Transparency), require pre-approval of access (Access Approval), or protect unencrypted data-in-transit through Google's infrastructure (default at-rest encryption addresses a different concern). Each control fills a different gap.
C
Distractor review
All four controls are redundant and address the same threat — customers only need to enable one of them
Each control addresses a different threat vector. Default encryption protects physical media. CMEK provides cryptographic customer control. Access Transparency provides visibility. Access Approval provides veto power. They are complementary, not redundant.
D
Best answer
The four controls form complementary layers: default encryption protects physical storage, CMEK gives cryptographic customer control (revocable), Access Transparency provides visibility into Google personnel access, and Access Approval gives customers veto power — together addressing infrastructure attacks, insider threats, and provider access concerns
This correctly describes the layered defense. Default encryption: protects against physical media theft. CMEK: customer controls the key — can cryptographically revoke Google's ability to decrypt. Access Transparency: audit trail of provider access. Access Approval: proactive veto before access. Together they provide defense at every layer of the provider access concern.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

Question 1
A traditional retailer currently maintains its own data centers, purchasing servers every 3–5 years and paying for facilities, power, and staff regardless of demand. When it migrates its workloads to the public cloud, which change in cost model does it experience?
Question 2
An e-commerce company plans its infrastructure for peak shopping events (e.g., Black Friday) which drive 50× normal traffic. On-premises, they must maintain 50× capacity year-round. In the cloud, they provision 50× capacity only during peak periods. Which cloud characteristic enables this cost optimization?

FAQ
Questions learners often ask
What does this GCDL question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: The four controls form complementary layers: default encryption protects physical storage, CMEK gives cryptographic customer control (revocable), Access Transparency provides visibility into Google personnel access, and Access Approval gives customers veto power — together addressing infrastructure attacks, insider threats, and provider access concerns — These four controls form a comprehensive layered approach: (1) Default encryption protects data from physical media theft. (2) CMEK gives customers cryptographic control — they can revoke access by deleting keys. (3) Access Transparency provides visibility into when Google personnel access customer data. (4) Access Approval requires customer pre-approval before Google can access data. Together they address different threat vectors: infrastructure attacks, insider threats, and provider access concerns.
What should I do if I get this GCDL question wrong?
Identify which GCDL exam domain this question belongs to, then review the specific concept being tested. Practise related questions in that domain and focus on understanding why each wrong answer is tempting — not just why the correct answer is right.
