PCNE Practice Question: Managing, Monitoring, and Optimising Network Operations
An organization wants to reduce egress costs for data sent from Compute Engine instances to users worldwide. Which TWO approaches should they consider? (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
✓
Deploy instances in multiple regions closer to users.
Cloud CDN caches content at edge locations, reducing egress from origin. Using a Premium Tier network routes traffic over Google's network, which may not reduce egress cost but improves performance; however, Standard Tier egress is cheaper than Premium Tier for internet egress. For reducing costs, Cloud CDN and using Standard Tier (if acceptable) can help. But among the options, Cloud CDN and placing instances in multiple regions (to serve users locally) reduce 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.
- ✗
Enable Private Google Access to avoid internet egress for Google APIs.
Why it's wrong here
This reduces egress for Google API traffic, not user traffic.
- ✓
Deploy instances in multiple regions closer to users.
Why this is correct
Regional deployment reduces cross-region and internet egress costs.
- ✗
Use global load balancers instead of regional load balancers.
Why it's wrong here
Global load balancers use Premium Tier, which may increase cost.
- ✓
Use Cloud CDN to cache content at Google's edge locations.
Why this is correct
Cloud CDN reduces origin egress by serving cached content.
- ✗
Use Premium Tier networking to route traffic over Google's network.
Why it's wrong here
Premium Tier is more expensive for egress than Standard Tier.
