This PCA practice question tests your understanding of ensure solution and operations reliability. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 user-uploaded content. They want to ensure that the data is highly durable and protected against accidental deletion. Which two features should they enable? (Choose two.)
Requester pays.
Why wrong: Requester pays is a billing configuration.
Lifecycle management.
Why wrong: Lifecycle management is for automated deletion, not protection.
Object versioning.
Versioning protects against accidental deletion or overwrite.
Bucket retention policy.
Retention policy prevents deletion for a specified period.
Uniform bucket-level access.
Why wrong: Uniform access controls access, not durability.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Object versioning.
Options A and B are correct: Object versioning preserves previous versions, and retention policy prevents deletion until the retention period ends. Option C lifecycle management is for automated deletion. Option D requester pays is for billing. Option E uniform bucket-level access is for access control.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
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.
Detailed technical explanation
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
