- A
Use a lifecycle rule to delete objects that are older than 365 days
If data is truly unneeded, deleting it eliminates storage costs entirely.
- B
Set a lifecycle rule to transition objects older than 90 days to Coldline storage class
Why wrong: Coldline is for data accessed less than once a quarter, not less than once a year. Archive is cheaper.
- C
Rename objects to start with 'archive/' to reduce costs
Why wrong: Object naming does not affect storage costs. Cost is based on storage class and amount of data.
- D
Set a lifecycle rule to transition objects older than 365 days to Archive storage class
Archive storage class is the cheapest for long-term archival data accessed less than once a year.
- E
Set a lifecycle rule to transition objects older than 30 days to Nearline storage class
Why wrong: Nearline is for data accessed less than once a month, not less than once a year. It is more expensive than Archive.
Google PCA Practice Question: Analysing and Optimising Technical and Business Processes
This PCA practice question tests your understanding of analysing and optimising technical and business processes. 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 wants to reduce Cloud Storage costs for archival data that is accessed less than once a year. They have data stored in Standard storage class. Which TWO actions should they take? (Choose TWO.)
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
Use a lifecycle rule to delete objects that are older than 365 days
Using lifecycle policies to transition from Standard to Archive storage class reduces cost for rarely accessed data. Also, deleting unnecessary objects reduces storage. Coldline is for 90 days, Nearline for 30 days; Archive is for long-term archival. Changing object names does not reduce cost.
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
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
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.
Real-world example
How this comes up in practice
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.
