You Have a Batch Workload That Runs Every Night and Uses

You have a batch workload that runs every night and uses a large number of virtual machines (VMs) . It is fault-tolerant and can tolerate some of the VMs being terminated. The current cost of VMs is too high. What should you do?

A) Run a test using simulated maintenance events. If the test is successful, use preemptible N1 Standard VMs when running future jobs.
B) Run a test using simulated maintenance events. If the test is successful, use N1 Standard VMs when running future jobs.
C) Run a test using a managed instance group. If the test is successful, use N1 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.
