Question #: 78
Topic #: 1

[All Professional Cloud Architect (PR000213) Questions]

Your development team has installed a new Linux kernel module on the batch servers in Google Compute Engine (GCE) virtual machines (VMs) to speed up the nightly batch process. Two days after the installation, 50% of web application deployed in the same

nightly batch run. You want to collect details on the failure to pass back to the development team. Which three actions should you take? Choose 3 answers

AUse Stackdriver Logging to search for the module log entries.

BRead the debug GCE Activity log using the API or Cloud Console.

CUse gcloud or Cloud Console to connect to the serial console and observe the logs.

DIdentify whether a live migration event of the failed server occurred, using in the activity log.

EAdjust the Google Stackdriver timeline to match the failure time, and observe the batch server metrics.

FExport a debug VM into an image, and run the image on a local server where kernel log messages will be displayed on the native screen.

Show Suggested Answer

Suggested Answer: B

The practice for managing logs generated on Compute Engine on Google Cloud is to install the Cloud Logging agent and send them to Cloud Logging.

The sent logs will be aggregated into a Cloud Logging sink and exported to Cloud Storage.

The reason for using Cloud Storage as the destination for the logs is that the requirement in question requires setting up a lifecycle based on the storage period.

In this case, the log will be used for active queries for 30 days after it is saved, but after that, it needs to be stored for a longer period of time for auditing purposes.

If the data is to be used for active queries, we can use BigQuery's Cloud Storage data query feature and move the data past 30 days to Coldline to build a cost-optimal solution.

Therefore, the correct answer is as follows

1. Install the Cloud Logging agent on all instances.

Create a sync that exports the logs to the region's Cloud Storage bucket.

3. Create an Object Lifecycle rule to move the files to the Coldline Cloud Storage bucket after one month. 4.

4. set up a bucket-level retention policy using bucket locking.'

F sounds a bit extreme, is it really necessary to export a VM?

I feel like adjusting the Stackdriver timeline to match the failure time is important, but I wonder if we should also check for live migration events.

I practiced connecting to the serial console with gcloud, but I can't recall if that's the most effective way to gather logs for this situation.

I think checking the debug GCE Activity log could be really useful, especially since it might show what happened right before the failures.

I remember something about using Stackdriver for logging, but I'm not sure if it's the best first step here.

I'm feeling pretty confident about this one. The key is to collect detailed information from multiple sources to help the development team identify the root cause. I'll make sure to cover all the bases with A, D, and E.

This seems straightforward enough. I'd go with A, B, and C - using the logging and console tools to gather as much information as possible about the failures.

Okay, I think I've got a good strategy here. I'll start by checking the Stackdriver logs for any relevant entries from the new kernel module. Then I'll look at the GCE activity log to see if there were any live migration events that could be related to the failures.

Okay, let me think this through. I know site maps and link-based navigation aren't the right answers, so I'm leaning towards either social navigation or breadcrumb navigation. I'll have to weigh the pros and cons of each.

D and E could also be helpful, but I'm not sure if they're as important as the first three. Identifying any live migration events and checking the Stackdriver metrics might provide additional context.
