QUESTION: 7

Your team is designing a new application for deployment both inside and outside Google Cloud Platform (GCP). You need to collect detailed metrics such as system resource utilization. You want to use centralized GCP services while minimizing the amount of work required to set up this collection system.
What should you do?

Import the Stackdriver Profiler package, and configure it to relay function timing data to Stackdriver for further analysis.
Import the Stackdriver Debugger package, and configure the application to emit debug messages with timing information.
Instrument the code using a timing library, and publish the metrics via a health check endpoint that is scraped by Stackdriver.
Install an Application Performance Monitoring (APM) tool in both locations, and configure an export to a central data storage location for analysis.

Answer(s): A

Explanation:

The easiest way to collect detailed metrics such as system resource utilization is to import the Stackdriver Profiler package, and configure it to relay function timing data to Stackdriver for further analysis. This way, you can use centralized GCP services without modifying your code or setting up additional tools.

QUESTION: 8

Your application images are built and pushed to Google Container Registry (GCR). You want to build an automated pipeline that deploys the application when the image is updated while minimizing the development effort.
What should you do?

Use Cloud Build to trigger a Spinnaker pipeline.
Use Cloud Pub/Sub to trigger a Spinnaker pipeline.
Use a custom builder in Cloud Build to trigger a Jenkins pipeline.
Use Cloud Pub/Sub to trigger a custom deployment service running in Google Kubernetes Engine (GKE).

Answer(s): B

Explanation:

https://cloud.google.com/architecture/continuous-delivery-toolchain-spinnaker-cloud https://spinnaker.io/guides/user/pipeline/triggers/pubsub/ The most efficient way to build an automated pipeline that deploys the application when the image is updated is to use Cloud Pub/Sub to trigger a Spinnaker pipeline. This way, you can leverage the built-in integration between GCR and Cloud Pub/Sub, and use Spinnaker as a continuous delivery platform for deploying your application .
