SAA-C03 Question 408
Single answerA company is running a database workload on an Amazon EC2 instance and requires a storage solution that provides low latency and high IOPS for frequent read and write operations. The database also needs to handle high transaction volumes efficiently. Which Amazon EBS volume type is the most suitable for this workload?
- A
General Purpose SSD (gp3)
- B
Provisioned IOPS SSD (io2)
- C
Throughput Optimized HDD (st1)
- D
Cold HDD (sc1)
Show answer and explanation
Correct answer: B
Explanation
Provisioned IOPS SSD (io2) volumes are specifically designed for high-performance transactional workloads that require high IOPS and low latency, such as databases. While General Purpose SSD (gp3) is versatile, it does not match the performance levels of io2 for high-transaction workloads. Throughput-optimized and cold HDD volumes are tailored for sequential workloads and infrequent access, respectively, and do not meet the performance needs of the database in this scenario.
- A. Incorrect.
General Purpose SSD (gp3) provides a good balance of price and performance for a variety of workloads, but it may not meet the high IOPS and low latency requirements of a high-transaction database workload.
- B. Correct.
Provisioned IOPS SSD (io2) is designed for applications requiring high performance and low latency. It offers the highest IOPS performance and durability among EBS volume types, making it the best choice for this database workload.
- C. Incorrect.
Throughput Optimized HDD (st1) is optimized for large, sequential workloads such as big data and log processing. It is not suitable for workloads requiring high IOPS or low latency, such as databases.
- D. Incorrect.
Cold HDD (sc1) is the least expensive EBS volume type, designed for infrequent access workloads. It is not suitable for databases requiring frequent and high-performance access.
