[All Associate Cloud Engineer Questions]

For analysis purposes, you need to send all the logs from all of your Compute Engine instances to a BigQuery dataset called platform-logs. You have already installed the Stackdriver Logging agent on all the instances. You want to minimize cost. What should you do?

A1. Give the BigQuery Data Editor role on the platform-logs dataset to the service accounts used by your instances.2. Update your instances' metadata to add the following value: logs-destination: bq://platform-logs.

B1. In Stackdriver Logging, create a logs export with a Cloud Pub/Sub topic called logs as a sink.2. Create a Cloud Function that is triggered by messages in the logs topic.3. Configure that Cloud Function to drop logs that are not from Compute Engine and to insert Compute Engine logs in the platform-logs dataset.

C1. In Stackdriver Logging, create a filter to view only Compute Engine logs.2. Click Create Export.3. Choose BigQuery as Sink Service, and the platform-logs dataset as Sink Destination.

D1. Create a Cloud Function that has the BigQuery User role on the platform-logs dataset.2. Configure this Cloud Function to create a BigQuery Job that executes this query:INSERT INTO dataset.platform-logs (timestamp, log)SELECT timestamp, log FROM compute.logsWHERE timestamp > DATE_SUB(CURRENT_DATE(), INTERVAL 1 DAY)3. Use Cloud Scheduler to trigger this Cloud Function once a day.

Suggested Answer: D

Instance groups are collections of virtual machine (VM) instances that you can manage as a single entity. Instance groups can help you simplify the management of multiple instances, reduce operational costs, and improve the availability and performance of your applications. Instance groups support autoscaling, which automatically adds or removes instances from the group based on increases or decreases in load. Autoscaling helps your applications gracefully handle increases in traffic and reduces cost when the need for resources is lower. You can set the autoscaling policy based on CPU utilization, load balancing capacity, Cloud Monitoring metrics, or a queue-based workload. In this case, since the video encoding software is CPU-intensive, setting the autoscaling based on CPU utilization is the best option to ensure high availability and optimal performance.Reference:

I'd go with Option B, it's like a three-course meal of cloud services - Pub/Sub, Cloud Functions, and BigQuery. Yum, yum! Just hope the chef doesn't overcook the logs.

Option A seems like the easiest solution, but I'm not sure it's the most cost-effective. Granting permissions and updating instance metadata sounds simple enough, but I wonder if there might be some hidden gotchas.

Hmm, Option D sounds pretty interesting. Automating the BigQuery job with a Cloud Function and Cloud Scheduler could be a clever way to handle this. Though, I'm a bit concerned about the potential for extra costs with all the moving parts.

I'm leaning towards Option C. It's a bit more straightforward, and I like the ability to create a filter to only export the Compute Engine logs. Plus, BigQuery integration is built-in, so it's a simple one-stop solution.

Option B looks like the most efficient solution to me. Using Cloud Pub/Sub and a Cloud Function to filter and insert the logs directly into BigQuery seems like a great way to automate the process and minimize costs.

I think Option B is the way to go. It streamlines the process and ensures that only the necessary logs are stored in the platform-logs dataset.
