PCNE Practice Question: Managing, Monitoring, and Optimising Network Operations
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.
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 Cloud Armor to block non-European traffic
Why it's wrong here
Blocking traffic does not reduce egress for allowed traffic and may affect users.
- ✓
Nothing; Cloud CDN already minimizes egress costs
Why this is correct
Cloud CDN serves from edge locations, reducing egress for all users, including those in Europe.
- ✗
Deploy a regional load balancer in Europe
Why it's wrong here
A regional load balancer would require origin also in Europe to avoid cross-region egress; Cloud CDN already reduces egress without infrastructure changes.
- ✗
Enable Private Google Access
Why it's wrong here
Private Google Access avoids internet egress for Google APIs, not for user traffic.
