1Z0-1067-25 Question 54
Select 2Your organization has an analytics platform running on Oracle Cloud Infrastructure (OCI) with a significant number of ephemeral workloads that only run for short periods. However, the monthly bill has increased substantially due to on-demand instances and multiple block volumes remaining attached to idle workloads. Which two cost optimization strategies would best address this situation?
- A
Use OCI Preemptible (Spot) Instances for intermittent workloads that can tolerate interruptions
- B
Implement maximum shape sizes for all compute instances to ensure high performance at all times
- C
Disable budgets to avoid overhead associated with budget notifications
- D
Detach or delete block volumes when ephemeral workloads finish running
- E
Disable cost-tracking tags to reduce tagging complexity
Show answer and explanation
Correct answers: A, D
Explanation
Preemptible (Spot) Instances are a recommended cost optimization approach for workloads that can be interrupted, as they have a lower price than on-demand instances. Additionally, detaching or deleting block volumes once the workload is completed prevents unnecessary storage charges. These two steps align with OCI cost management best practices, as outlined in Oracle� documentation on implementing budgets and using preemptible instances for ephemeral use cases.
- A. Correct.
Correct. OCI Preemptible (Spot) Instances are offered at a lower cost than on-demand instances. They are well-suited for workloads that can tolerate interruptions, making them an excellent choice to reduce costs for short-lived tasks.
- B. Incorrect.
Incorrect. Maximizing shape sizes increases resource capacity but also raises costs. This strategy may be useful for critical high-performance applications, but it� not cost effective for sporadic or ephemeral workloads that do not need constant high performance.
- C. Incorrect.
Incorrect. Budgets and budget alerts help you track spending and detect cost anomalies early. Disabling budgets might make it harder to identify and address cost overruns in real time.
- D. Correct.
Correct. Detaching or deleting block volumes associated with ephemeral workloads once they complete is a key cost-saving measure. Unused attached storage can accumulate significant costs if not decommissioned promptly.
- E. Incorrect.
Incorrect. Cost-tracking tags are helpful for visibility into resource consumption and cost allocation. Disabling them would reduce your ability to forecast, analyze, or optimize costs effectively.
