1Z0-1072-25 Question 193
Single answerYou are migrating a departmental analytics workload that processes 2 TB of data daily. The workload requires moderately high throughput for daily data ingestion but is also cost-conscious. Multiple concurrent reads and writes occur during the ingestion process, but not at extremely high or continuous volumes. Which Block Volume performance tier should you choose for the best balance of cost and performance?
- A
Basic Performance
- B
Balanced Performance
- C
Higher Performance
- D
Ultra High Performance
Show answer and explanation
Correct answer: B
Explanation
Balanced Performance is recommended for scenarios requiring a balance between cost and capable throughput for moderate to high I/O demands. Basic might be too limited for such a workload, while Higher Performance and Ultra High Performance can be unnecessarily expensive for daily ingestion needs. For more information, refer to the official Oracle Cloud Infrastructure documentation on Block Volume performance tiers.
- A. Incorrect.
Option 1: Basic Performance. Incorrect. While Basic Performance offers the lowest cost tier, it may not meet the moderately high throughput needed for a 2 TB daily ingestion workload. This tier is best suited for smaller or less frequently accessed workloads where the prioritization is minimal cost over performance.
- B. Correct.
Option 2: Balanced Performance. Correct. Balanced Performance is designed to provide a good trade-off between cost and performance. It supports moderate to high throughput and can handle multiple concurrent read/write operations for a daily ingestion workflow without incurring the higher costs of more advanced tiers.
- C. Incorrect.
Option 3: Higher Performance. Incorrect. Although Higher Performance offers greater IOPS and throughput, it also comes with higher costs. This tier is more suitable for operations requiring consistently high IOPS or very low latency beyond the capability of the Balanced tier.
- D. Incorrect.
Option 4: Ultra High Performance. Incorrect. Ultra High Performance is the most expensive tier, intended for the highest workloads with extremely demanding and continuous read/write operations. This workload does not justify that level of performance investment.
