Explanation:
The correct answer is C. Using Compute Engine with preemptible VM instances is the best choice for batch processing jobs that take around 2 hours and are run nightly, as they can significantly reduce costs. Preemptible VMs are up to 80% cheaper than standard instances. If some instances stop during processing, the job slows but does not completely stop, making this an ideal option for cost-effective batch processing.
Ultimate access to all questions.
You are tasked with selecting and configuring compute resources for a set of nightly batch processing jobs that typically take around 2 hours to complete. Your goal is to optimize these resources to minimize service costs. What steps should you take to achieve this?
A
Select Google Kubernetes Engine. Use a single-node cluster with a small instance type.
B
Select Google Kubernetes Engine. Use a three-node cluster with micro instance types.
C
Select Compute Engine. Use preemptible VM instances of the appropriate standard machine type.
D
Select Compute Engine. Use VM instance types that support micro bursting.
