- A
Use Cloud Armor to block non-European traffic
Why wrong: Blocking traffic does not reduce egress for allowed traffic and may affect users.
- B
Nothing; Cloud CDN already minimizes egress costs
Cloud CDN serves from edge locations, reducing egress for all users, including those in Europe.
- C
Deploy a regional load balancer in Europe
Why wrong: A regional load balancer would require origin also in Europe to avoid cross-region egress; Cloud CDN already reduces egress without infrastructure changes.
- D
Enable Private Google Access
Why wrong: Private Google Access avoids internet egress for Google APIs, not for user traffic.

PCNE Practice Question: Managing, Monitoring, and Optimising Network Operations
This PCNE practice question tests your understanding of managing, monitoring, and optimising network operations. 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.
An organization has a global web application deployed behind an External HTTPS Load Balancer. They want to reduce egress costs for users in Europe who are served from the same region. The application is already using Cloud CDN. Which additional action will MOST effectively reduce egress costs for these users?
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
✓
Nothing; Cloud CDN already minimizes egress costs
Cloud CDN caches content at edge locations closer to users, reducing egress costs by serving cached responses from the edge. For users in Europe, if the origin is in the US, Cloud CDN will serve from European caches after the first request, minimizing cross-region egress.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

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.
