C) Enable and review the health check logs. Review the error responses in Cloud Logging. and E) Validate the health of the backend service. Enable logging on the load balancer and identify the error response in Cloud Logging. Determine the cause of the error by reviewing the statusDetails log field.
A) Delete the load balancer and backend services. Create a new passthrough Network Load Balancer. Configure a failover group of VMs for the backend.
B) Access a VM in the VPC through SSH and try to access a backend VM directly. If the request is successful from the VM, increase the quantity of backends.

[All Professional Cloud Network Engineer Questions]

Your organization recently exposed a set of services through a global external Application Load Balancer. After conducting some testing, you observed that responses would intermittently yield a non-HTTP 200 response. You need to identify the error. What should you do? (Choose 2 answers)

Show Suggested Answer Hide Answer
Suggested Answer: C, E

To troubleshoot the intermittent non-HTTP 200 responses, you should enable and review health check logs and log the backend service's responses in Cloud Logging. Reviewing the statusDetails field helps identify the cause of the error. Enabling logging on the load balancer and backend service provides visibility into the issue.

I'm a bit unsure about the best approach here. I feel like accessing the VM directly, as mentioned in option B, could help, but it seems like a roundabout way to troubleshoot.
