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
✓
Serverless NEG
A serverless NEG is a backend that points to a Cloud Run service, and a backend service is needed to define health checks and other settings.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Serverless NEG
Why this is correct
Required: defines the Cloud Run service as a backend.
- ✓
Backend service
Why this is correct
Required: backend service ties the NEG to the load balancer.
- ✗
Health check
Why it's wrong here
Health checks are configured as part of backend service, but not a separate component; also not required for serverless NEGs.
- ✗
Target proxy
Why it's wrong here
Target proxy is required for the load balancer, but not directly tied to the NEG; the question asks components to route to Cloud Run via serverless NEG, and backend service is more directly related.
- ✗
URL map
Why it's wrong here
URL map is required for routing, but the question asks for two components; backend service and serverless NEG are the ones directly involved.
