Exam Professional Cloud DevOps Engineer topic 1 question 25 discussion

A is correct

A is correct.

Option A

Answer is A

A. Purchase Committed Use Discounts. Explanation: When you know that you will have a workload running on a fixed set of instances for several months, you can take advantage of Committed Use Discounts to lower the costs. These discounts provide a lower, sustained usage rate for a committed period of time (e.g. 1 or 3 years) in exchange for committing to use a certain number of virtual machine (VM) instances or n1-standard hours. This is a good choice because you can lower costs without any performance implications and the workload is stable with the exact amount of resources allocated to it.

Answer is A

"business-critical workload ....... for several months", preemptible is not suitable in here. "The workload is stable with the exact amount of resources allocated to it" , exclude B. A should be OK.

C. Since the requirement is to run “business-critical workloads”, preemptible instances not ideal since they can be stopped randomly.

A - Committed usage discounts is the right answer as we have a consistent workload for a known duration.

A is correct, committed usage discounts

A is correct

In study guide you can find “user discount” and “preemptable”. In this case performance are qequired, so C is not possible. A for sure

Answer is A => several months can be up to or more than a year C is wrong because 1. Business critical workload, you don't want that stopped randomly 2. Preemptible requires the workload to be resumable -> not stated in the question

please look at the question: "You need to run a business-critical workload". this is not a good idea to go for preemtible vms as it can effect performance and bussiness. I go for A.

B and D is not related to cost because of stable workload. Now, really unsure between A and C. A: several months vs. at least one year C: a fixed set of Compute Engine instances vs. preemptable I think I will choose C because using preemptable, we can still try to find a way to create a new preemptable VM (same or different zones) if existing one is terminated.

A) not correct committed discounts 1-3 years, we have several months B) MIG - not correct - stable workloads C) Preemptible vm's - not correct they last only 24 hours D) not sure--Unmanaged instance groups-- do they offer cost savings?
