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
✓
The serverless NEG does not support health checks
Serverless NEGs do not require health checks; the health check configuration is ignored. The error may be due to incorrect IAM permissions or service account.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The Cloud Run service is not deployed
Why it's wrong here
That would cause a different error, not a health check error.
- ✗
The health check interval is too short
Why it's wrong here
Serverless NEGs ignore health checks.
- ✗
The SSL certificate is misconfigured
Why it's wrong here
SSL certificate issues would cause SSL errors, not health check errors.
- ✓
The serverless NEG does not support health checks
Why this is correct
Correct: serverless NEGs do not have health checks; the error is likely due to something else.
