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 an instance group, then a health check, then a backend service, then a URL map, then a target proxy, then a forwarding rule

  Why this is correct

  This is the correct order because the backend service requires both the instance group and health check, the URL map references the backend service, and the target proxy and forwarding route traffic to the URL map.

• ✗

  Create a health check, then an instance group, then a backend service, then a URL map, then a target proxy, then a forwarding rule

  Why it's wrong here

  This is incorrect because while you can create a health check before an instance group, the typical and recommended order in GCP is to create the instance group first, as it defines the backend resources.

• ✗

  Create an instance group, then a backend service, then a health check, then a URL map, then a target proxy, then a forwarding rule

  Why it's wrong here

  This order attempts to create the backend service before the health check exists. In Google Cloud, a backend service must reference a health check at the moment it is created—the API requires a healthCheck field, so without an already-created health check the backend service creation fails. Creating the instance group first is valid, but the backend service cannot be built before its health check. Only after the health check exists can the backend service be created, followed by the URL map, target proxy, and forwarding rule.

• ✗

  Create an instance group, then a health check, then a URL map, then a backend service, then a target proxy, then a forwarding rule

  Why it's wrong here

  This sequence places the URL map ahead of the backend service. A URL map is a routing configuration that maps incoming host and path rules to backend services, so it can only be constructed once the backend service exists to reference. Creating the instance group and health check first is correct, but the URL map must come after the backend service, not before. In this order, URL map creation would fail because the backend service is not yet available for it to reference.
