[All Professional Cloud Network Engineer Questions]

You have enabled HTTP(S) load balancing for your application, and your application developers have reported that HTTP(S) requests are not being distributed correctly to your Compute Engine Virtual Machine instances. You want to find data about how the request are being distributed.
Which two methods can accomplish this? (Choose two.)

A. On the Load Balancer details page of the GCP Console, click on the Monitoring tab, select your backend service, and look at the graphs.
B. In Stackdriver Error Reporting, look for any unacknowledged errors for the Cloud Load Balancers service.
C. In Stackdriver Monitoring, select Resources > Metrics Explorer and search for https/request_bytes_count metric.
D. In Stackdriver Monitoring, select Resources > Google Cloud Load Balancers and review the Key Metrics graphs in the dashboard.
E. In Stackdriver Monitoring, create a new dashboard and track the https/backend_request_count metric for the load balancer.

Answers are A and E. A is very clear. Both C and E look OK per https://cloud.google.com/load-balancing/docs/https/https-logging-monitoring But, this question is about "find data about how the request are being distributed", so, E is the right answer as it is monitoring backend_request_count

Selected Answer: AE

A) On the Load Balancer details page of the GCP Console, click on the Monitoring tab, select your backend service, and look at the graphs: This method will give you data about how the requests are being distributed to the backend instances. You can see data like request rate, request count, latency, and errors. E) In Stackdriver Monitoring, create a new dashboard and track the https/backend_request_count metric for the load balancer: By creating a dashboard and tracking the https/backend_request_count metric, you can see the total number of requests made to the backend instances. This will give you an idea of the load on your backend instances and help you determine if there is an issue with load balancing.

Option B is incorrect because Stackdriver Error Reporting is used for identifying application errors, and not for load balancer monitoring. Option D is incorrect because there is no Resources > Google Cloud Load Balancers option in Stackdriver Monitoring. The correct option is Resources > Metrics Explorer, where you can search for relevant load balancer metrics. Option C is incorrect because the https/request_bytes_count metric only tracks the amount of bytes sent from the client to the load balancer, and does not provide any information about request distribution.

I'm going with A & E, since both C and D are not following the proper path. Indeed, you need to select Monitoring -> Metric Explorer -> Resource/Metric and then filter for the Load Balancer you'd like to analyze.

Vote for A & E Need "backend"_request_count for us to find data about how the request are being "distributed"

To view the predefined dashboards for only your external HTTP(S) load balancers, select the dashboard named External HTTP(S) LB, instead of Google Cloud LB. To view a list of dashboards for all your Google Cloud load balancers, select the dashboard named Google Cloud Load Balancers. https://cloud.google.com/load-balancing/docs/https/https-logging-monitoring#predefined-dashboards In this question, you have used HTTP(S) LB and need to some troubleshooting on it.why not direct to choose HTTP LB ? so I think D is not accurate in this case, E should be better.

I would choose A and C. A - is obvious and easiest way to see the traffic distribution to the backend instances. D - On Stackdriver Monitoring console, Monitoring metrics for Load balancer already include a list of pre-defined metrics, e.g Backend request count, thus, there is no need to create new dashboard and metric, thus E is NOT correct.

I think the answer will be A,E as https/backend_request_count will provide the "The number of requests sent from the external HTTP(S) load balancer to the backends" which is requested in the question about how the distribution is done to the backend.
