Discuss Google Professional Cloud Network Engineer Exam Topic 2 Question 97

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)

ADelete the load balancer and backend services. Create a new passthrough Network Load Balancer. Configure a failover group of VMs for the backend.

BAccess 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.

CEnable and review the health check logs. Review the error responses in Cloud Logging.

DValidate the health of the backend service. Enable logging for the backend service and identify the error response in Cloud Logging. Determine the cause of the error by reviewing the statusDetails log field.

EValidate 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.

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.

Can we really trust the logs to give us the full picture?

E looks good too, logging is key for troubleshooting.

Leontine 11 months ago

Wait, why would you delete the load balancer? Seems extreme.

Vanesa 11 months ago

Totally agree, health checks are crucial!

Breana 12 months ago

I think C and D are the best options here.

Davida 12 months ago

I vaguely recall a practice question where we had to troubleshoot load balancer issues. I think focusing on health checks and logs is key, so maybe C and E are the right choices here.

I think enabling logging is crucial for identifying issues. Options D and E both mention logging, but I wonder if one is better than the other for this scenario.

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.

Hubert 1 year ago

I remember we discussed the importance of health checks in our last study session. I think options C and D might be relevant since they both involve checking logs and health status.

Augustine 1 year ago

I'm a bit unsure about the network load balancer option. I'll need to research that a bit more to see if it's really the best solution.

Tu 1 year ago

I'm feeling pretty confident about this one. Validating the backend service health and reviewing the logs should help me identify the root cause.

Kaitlyn 1 year ago

Okay, I think the key here is to focus on troubleshooting the issue. Enabling logging and reviewing the error responses seems like a good place to start.

Ryan 1 year ago

Hmm, I'm a bit confused by the different load balancer options. I'll need to make sure I understand the differences before deciding.

Yolande 1 year ago

This looks like a tricky one. I'll need to carefully read through the options and think about the best approach.

Haha, option D is like throwing the baby out with the bathwater. Why not just fix the issue instead of starting from scratch?

Xuan 2 years ago

I agree, but we should also consider option C for a more thorough investigation.

Almeta 2 years ago

I agree, B and C are the best choices. Deleting and recreating the load balancer seems like overkill for this problem.

I think we should try option A first.

Bulah 2 years ago

Option B and C seem like the way to go. Checking the health check logs and the load balancer logs should help identify the issue.
