Topic #: 1

[All Associate Cloud Engineer Questions]

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?

ARun a test using simulated maintenance events. If the test is successful, use preemptible N1 Standard VMs when running future jobs.

BRun a test using simulated maintenance events. If the test is successful, use N1 Standard VMs when running future jobs.

CRun 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.

DRun a test using N1 standard VMs instead of N2. If the test is successful, use N1 Standard VMs when running future jobs.

Wait, can we really rely on preemptible VMs for critical jobs?

Using managed instance groups is a solid approach too.

Not sure if preemptible VMs are reliable enough for this workload.

I agree, option A sounds like the best choice.

Preemptible VMs can save a lot of money!

I feel like we practiced a similar question about VM types, and I think N1 Standard VMs are generally cheaper, but I’m not sure if they’re the best choice here.

I think using a managed instance group could help with scaling, but I’m not clear on how that impacts costs compared to just using preemptible VMs.

I remember we discussed preemptible VMs in class, and they seem like a good option since the workload is fault-tolerant. But I'm not entirely sure if they would work for every job.

I vaguely recall something about testing maintenance events, but I can't remember if that was specifically for preemptible VMs or just any VM type.

Hmm, this seems like a tricky one. I'll need to carefully read through the options and think about the business scenario to figure out the right approach.

Data consistency is critical, so I want to make sure I get this right. Undo data and isolation level seem like obvious choices, but the other two options have me a bit stumped. I'll have to review my notes and try to reason this through.
