Google Professional Cloud DevOps Engineer Question 175
Select 2Google Cloud PlatformYour team is building a cost-efficient cloud infrastructure on Google Cloud for a new project with predictable workloads that will run 24/7 for at least a year. The project requires significant compute resources and will also involve data transfer between regions. As the DevOps engineer, which of the following strategies should you implement to optimize costs while meeting workload requirements?
- A
Purchase committed-use discounts for compute resources.
- B
Use sustained-use discounts for workloads that run 24/7.
- C
Select Standard Network Tier for internal data transfers between regions.
- D
Choose Premium Network Tier for external-facing traffic that requires low latency.
- E
Leverage preemptible VMs for critical components of the workload.
Show answer and explanation
Correct answers: A, D
Explanation
For predictable, long-term workloads, committed-use discounts are the most cost-effective option compared to sustained-use discounts. Choosing the Premium Network Tier ensures low latency and reliability for external-facing traffic, which is a common requirement for production workloads. While Standard Network Tier and preemptible VMs can save costs, they are unsuitable for scenarios requiring high performance and reliability.
- A. Correct.
Correct: Committed-use discounts provide significant cost savings for predictable workloads that will run continuously over a long period, such as a year or more.
- B. Incorrect.
Incorrect: Sustained-use discounts are automatically applied for workloads that run continuously, but they are less cost-effective compared to committed-use discounts for predictable, long-term usage.
- C. Incorrect.
Incorrect: Standard Network Tier is more cost-effective but is unsuitable for inter-region data transfers where performance and reliability are critical.
- D. Correct.
Correct: Premium Network Tier is optimized for low-latency, high-performance traffic, which is ideal for external-facing applications requiring high reliability.
- E. Incorrect.
Incorrect: Preemptible VMs are cost-effective but inappropriate for critical workloads, as they can be terminated at any time without notice.
