PCDOE Managing Google Cloud costs Practice Question
This PCDOE practice question tests your understanding of managing google cloud costs. 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.
Which THREE actions can help optimize Cloud Storage costs? (Choose three.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Nearline or Coldline storage classes for infrequently accessed data.
Option A is correct because Nearline and Coldline storage classes are designed for infrequently accessed data, offering lower storage costs compared to Standard storage. By choosing these classes for data that is accessed less than once a quarter or once a year, you reduce the per-GB storage charge, though you incur higher retrieval and early deletion fees. This directly optimizes costs when access patterns align with the class's intended use.
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 Nearline or Coldline storage classes for infrequently accessed data.
Why this is correct
These classes offer lower storage costs for infrequent access.
Related concept

✓
Enable Object Lifecycle management to transition objects to colder storage classes.
Why this is correct
Automatically moves data to cheaper storage based on rules.
Related concept
Read the scenario before looking for a memorised answer.
✓
Compress objects before uploading to reduce storage size.
Why this is correct
Compression reduces the number of bytes stored, lowering cost.

✗
Enable versioning on all buckets to protect against accidental deletion.
Why it's wrong here
Versioning increases storage costs due to multiple versions.
✗
Use Standard storage class for all objects to ensure low latency.
Why it's wrong here
Standard is expensive; using cheaper classes for infrequent data saves cost.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse data protection features (like versioning) or performance choices (like Standard class) with cost optimization actions, overlooking that versioning increases storage costs and Standard is the most expensive class.
Detailed technical explanation
How to think about this question
Object Lifecycle management (Option B) automates transitions between storage classes based on age or other conditions, such as moving objects from Standard to Nearline after 30 days, reducing manual intervention and ensuring cost efficiency. Compression (Option C) reduces the logical size of objects before upload, directly lowering the storage bytes billed, which is especially effective for compressible data like text or logs. Under the hood, Cloud Storage charges based on the actual stored size, so compression yields immediate savings.
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 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.
