Actual exam question for Google's Associate Cloud Engineer exam

Question #: 93
Topic #: 3

[All Associate Cloud Engineer Questions]

You want to deploy an application on Cloud Run that processes messages from a Cloud Pub/Sub topic. You want to follow Google-recommended practices. What should you do?

A1. Create a Cloud Function that uses a Cloud Pub/Sub trigger on that topic.2. Call your application on Cloud Run from the Cloud Function for every message.

B1. Grant the Pub/Sub Subscriber role to the service account used by Cloud Run.2. Create a Cloud Pub/Sub subscription for that topic.3. Make your application pull messages from that subscription.

C1. Create a service account.2. Give the Cloud Run Invoker role to that service account for your Cloud Run application.3. Create a Cloud Pub/Sub subscription that uses that service account and uses your Cloud Run application as the push endpoint.

D1. Deploy your application on Cloud Run on GKE with the connectivity set to Internal.2. Create a Cloud Pub/Sub subscription for that topic.3. In the same Google Kubernetes Engine cluster as your application, deploy a container that takes the messages and sends them to your application.

Show Suggested Answer

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 remember we discussed using Cloud Functions for Pub/Sub, but I'm not sure if that's the best approach for Cloud Run.

I think Option B might be the simplest solution. Granting the Pub/Sub Subscriber role and having the application pull messages directly from the subscription seems straightforward.

D, huh? Might as well throw in a kubernetes cluster, a few microservices, and a serverless function or two, just to be safe. Why keep it simple when you can make it complicated?

A? Really? Calling Cloud Run from a Cloud Function for every message? That's just adding an extra hop and potential failure point. Not a fan.

D seems a bit overkill, don't you think? Why bring in a whole GKE cluster just to connect Pub/Sub to Cloud Run? B or C are cleaner options.
