AWS Certified Solutions Architect Associate SAA-C03 Practice Question
A company requires block storage for its low-latency interactive workloads that involve frequent random reads and small to medium-sized I/O operations. However, the budget is limited, and they must choose a volume type that aligns with their cost constraints. Which Amazon EBS volume type BEST meets the company's requirements for both performance and cost optimization?
General Purpose SSD (gp3) volumes strike the right balance of price and performance for most transactional or interactive workloads. They deliver single-digit-millisecond latency, include 3,000 baseline IOPS at no extra charge, and let you scale IOPS and throughput independently-making them cost-efficient for workloads with frequent random reads. Provisioned IOPS SSD (io1/io2) can achieve higher performance but at a higher cost per GiB and per provisioned IOPS. Throughput Optimized HDD (st1) and Cold HDD (sc1) are HDD-backed; they emphasize sequential throughput, not random I/O, and have higher latency, so they do not meet the application's low-latency requirement.
