Google Cloud Professional Cloud Architect — Question 131

You need to migrate Hadoop jobs for your company's Data Science team without modifying the underlying infrastructure. You want to minimize costs and infrastructure management effort. What should you do?

Answer options

• A. Create a Dataproc cluster using standard worker instances.
• B. Create a Dataproc cluster using preemptible worker instances.
• C. Manually deploy a Hadoop cluster on Compute Engine using standard instances.
• D. Manually deploy a Hadoop cluster on Compute Engine using preemptible instances.

Correct answer: B

Explanation

The best option is B, as using preemptible worker instances in a Dataproc cluster significantly reduces costs while still providing the necessary resources for Hadoop jobs. Options A and C involve standard instances, which are more expensive, and D requires manual deployment, increasing management overhead and costs.
