Question #: 87
Topic #: 4

[All Professional Cloud Architect Questions]

You have an application that runs in Google Kubernetes Engine (GKE). Over the last 2 weeks, customers have reported that a specific part of the application returns errors very frequently. You currently have no logging or monitoring solution enabled on your GKE cluster. You want to diagnose the problem, but you have not been able to replicate the issue. You want to cause minimal disruption to the application. What should you do?

A1. Update your GKE cluster to use Cloud Operations for GKE.
2. Use the GKE Monitoring dashboard to investigate logs from affected Pods.

B1. Create a new GKE cluster with Cloud Operations for GKE enabled.
2. Migrate the affected Pods to the new cluster, and redirect traffic for those Pods to the new cluster.
3. Use the GKE Monitoring dashboard to investigate logs from affected Pods.

C1. Update your GKE cluster to use Cloud Operations for GKE, and deploy Prometheus.
2. Set an alert to trigger whenever the application returns an error.

D1. Create a new GKE cluster with Cloud Operations for GKE enabled, and deploy Prometheus.
2. Migrate the affected Pods to the new cluster, and redirect traffic for those Pods to the new cluster.
3. Set an alert to trigger whenever the application returns an error.

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.'

Option D sounds like a job for the 'Kubernetes Extreme Makeover' team. I hope they remember to leave the application's favorite snacks in the new cluster.

Option A? More like Option 'Ah, the simple life'! I'm all about that low-maintenance approach.

Option D seems like overkill. Creating a new cluster and migrating Pods just to enable Prometheus and set an alert seems like it would cause a lot of disruption to the application.

A) Update your GKE cluster to use Cloud Operations for GKE. Use the GKE Monitoring dashboard to investigate logs from affected Pods.

I'm a bit skeptical about Option C. Deploying Prometheus on the existing cluster might introduce more complexity than necessary, and setting an alert seems like a reactive approach.

I think we should update our GKE cluster to use Cloud Operations for GKE and check the logs from affected Pods.
