PCNE Configuring Network Services Practice Question
You are migrating an on-premises application to Google Cloud and need to connect it to Cloud Run services via a load balancer. The on-premises network uses a VPN to GCP. Which TWO components are required to route traffic from on-premises to a serverless NEG? (Choose 2)
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
✓
Regional Internal HTTP(S) Load Balancer
A hybrid connectivity NEG is used to route traffic to on-premises backends. For traffic from on-premises to serverless, you need a serverless NEG and an internal load balancer that can route to it. The hybrid NEG is for the reverse direction.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Regional Internal HTTP(S) Load Balancer
Why this is correct
Internal LB with serverless NEG can route internal traffic to Cloud Run.
- ✓
Serverless NEG
Why this is correct
Serverless NEG represents the Cloud Run service as a backend.
- ✗
Cloud Router
Why it's wrong here
Cloud Router is for dynamic routing, not a direct component.
- ✗
Hybrid connectivity NEG
Why it's wrong here
Hybrid NEG is for on-premises backends, not for serverless.
- ✗
Cloud VPN tunnel
Why it's wrong here
VPN tunnel is assumed, not a component of load balancing.
