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.
A DevOps engineer is reviewing GCP costs and notices high network egress charges. Which two actions can help reduce network egress costs? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Cloud CDN to cache content closer to users
Options A and B are correct. Using the same region for resources reduces inter-region egress. Cloud CDN caches content, reducing egress to the internet. Option C is not practical. Option D saves compute, not network. Option E increases egress by exposing globally.
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 preemptible VMs
Why it's wrong here
Preemptible VMs reduce compute costs, not network egress.
✗
Migrate all workloads to a single zone
Why it's wrong here
Zone migration does not significantly reduce network egress; regions matter more.
✓
Use Cloud CDN to cache content closer to users
Why this is correct
Cloud CDN reduces egress from origin to internet by serving cached content.

Read the scenario before looking for a memorised answer.
✓
Use the same region for all GCP resources that communicate with each other
Why this is correct
Inter-region egress is charged; same-region traffic is free.

✗
Use external load balancers with global access
Why it's wrong here
Global load balancers increase egress by directing traffic globally.
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.
