1Z0-1072-25 Question 197
Single answerYour enterprise data analytics platform on Oracle Cloud Infrastructure uses Block Volumes attached to a compute instance. The platform experiences cyclical demand spikes each month, requiring higher throughput only for a short reporting window, while normal usage remains moderate. You want to keep costs down but still meet peak performance requirements. Which approach correctly addresses this scenario?
- A
You must shut down the instance and provision new Block Volumes with the required performance tier each time a spike occurs.
- B
You can change the Block Volume� performance tier on demand using the OCI Console or API without detaching the volume.
- C
Block Volume performance tiers can only be changed once after creation, requiring a new volume for subsequent alterations.
- D
Switching performance tiers requires approval from Oracle Support to guarantee workload compatibility.
Show answer and explanation
Correct answer: B
Explanation
OCI� Block Volume performance tiers (e.g., Lower Cost, Balanced, Higher Performance) can be adjusted on-demand to match fluctuating workload requirements. This approach enables cost savings during normal operations while providing sufficient IOPS and throughput during peak usage. Refer to OCI documentation on Block Volume performance tiers for specific guidance and best practices regarding changing tiers in real-time.
- A. Incorrect.
Incorrect. OCI allows you to dynamically change the performance tier of an existing Block Volume without shutting down your instance or creating a new volume. This option implies a complete reprovisioning, which is unnecessary.
- B. Correct.
Correct. OCI Block Volume performance tiers can be changed at any time via the Console or API. This flexibility is specifically designed to handle cyclical demand spikes efficiently without downtime.
- C. Incorrect.
Incorrect. OCI supports multiple changes to Block Volume performance tiers, not just a single change. You do not need to recreate your volume after the first adjustment.
- D. Incorrect.
Incorrect. Performance tier changes do not require Oracle Support approval. You can switch tiers as needed to match performance requirements without a formal review process.
