PCNE Configuring Network Services Practice Question
A company wants to expose a web application running on Cloud Run globally with a single anycast IP address, using HTTP(S) load balancing and Cloud CDN for static content. The application should be accessible at https://app.example.com. What is the correct configuration?
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
✓
Create a global external HTTP(S) load balancer with a serverless NEG that points to the Cloud Run service.
Global HTTPS LB with serverless NEG targeting Cloud Run is the best practice for globally exposing serverless workloads with CDN. The other options either lack CDN (SSL Proxy), are regional (regional LB), or use incorrect NEG type (hybrid NEG for on-prem).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create a global SSL Proxy load balancer with a Cloud Run backend bucket.
Why it's wrong here
SSL Proxy load balancer is for TCP with SSL offload, not HTTP(S) and not suitable for Cloud Run.
- ✓
Create a global external HTTP(S) load balancer with a serverless NEG that points to the Cloud Run service.
Why this is correct
Global HTTPS LB with serverless NEG provides global anycast IP, CDN integration, and supports Cloud Run.
- ✗
Create a global TCP Proxy load balancer with a hybrid connectivity NEG.
Why it's wrong here
TCP Proxy is for TCP without SSL, and hybrid NEG is for on-prem backends, not Cloud Run.
- ✗
Create a regional external HTTP(S) load balancer with a serverless NEG.
Why it's wrong here
Regional LB provides a regional IP, not a global anycast IP.
