1Z0-1072-25 Question 195
Select 3You are designing storage for multiple workloads in your Oracle Cloud Infrastructure environment. One set of block volumes holds infrequently accessed data where cost is the biggest concern. Another set supports a development and testing environment with moderate performance requirements. Finally, you have a mission-critical OLTP system that performs frequent heavy database operations and requires consistently high throughput. Which of the following statements about choosing the most appropriate block volume performance tiers are correct?
- A
Balanced tier is well-suited for development/testing with moderate performance needs.
- B
Basic tier is ideal for rarely accessed data to minimize cost.
- C
Balanced tier is recommended for the mission-critical OLTP environment requiring consistently high throughput.
- D
Higher Performance or Ultra High Performance tiers address high throughput needs for the mission-critical OLTP environment.
Show answer and explanation
Correct answers: A, B, D
Explanation
Oracle Cloud Infrastructure provides multiple performance tiers (Basic, Balanced, Higher Performance, Ultra High Performance) for Block Volumes. Basic is cost-effective for data rarely accessed, Balanced meets moderate performance needs, and Higher/Ultra High Performance tiers deliver higher throughput and IOPS for production workloads like OLTP. For further details, refer to Oracle� official documentation on Block Volume performance tiers.
- A. Correct.
Option 1: Correct. Balanced tier offers moderate cost and performance, making it a good choice for dev/test workloads that don�t require the highest IOPS.
- B. Correct.
Option 2: Correct. Basic tier provides lower-cost storage with reduced performance, which is suitable for data that is infrequently accessed or archived.
- C. Incorrect.
Option 3: Incorrect. Balanced tier does not typically meet the throughput and IOPS demands of a mission-critical OLTP workload, which often requires higher performance levels.
- D. Correct.
Option 4: Correct. Higher Performance or Ultra High Performance tiers are appropriate for demanding workloads such as mission-critical OLTP systems that need consistently high IOPS and throughput.
