Explanation:
The correct answer is A. Spot VMs are highly affordable compute instances suitable for batch jobs and fault-tolerant workloads. They offer significant discounts compared to on-demand VMs. Since the workload can tolerate some of the VMs being terminated, using Spot VMs can significantly reduce costs while meeting the workload's requirements.
You manage a nightly batch processing workload that operates using a substantial number of virtual machines (VMs). This workload is designed to be fault-tolerant, meaning it can handle the termination of some VMs without compromising overall functionality. Currently, the high cost associated with these VMs is a concern. What steps can you take to reduce the cost?
A
Run a test using simulated maintenance events. If the test is successful, use Spot N2 Standard VMs when running future jobs.
B
Run a test using simulated maintenance events. If the test is successful, use N2 Standard VMs when running future jobs.
C
Run a test using a managed instance group. If the test is successful, use N2 Standard VMs in the managed instance group when running future jobs.
D
Run a test using N1 standard VMs instead of N2. If the test is successful, use N1 Standard VMs when running future jobs.
