A SysOps Administrator needs an Amazon EBS volume type for a big data application. The application data is accessed infrequently and stored sequentially. What EBS volume type will be the MOST cost-effective solution?
Suggested Answer:B🗳️
SC1 is backed by hard disk drives (HDDs) and provides the lowest cost per GB of all EBS volume types. It is ideal for less frequently accessed workloads with large, cold datasets. Similar to st1, sc1 provides a burst model: these volumes can burst up to 80 MB/s per TB, with a baseline throughput of 12 MB/s per TB and a maximum throughput of 250 MB/s per volume. For infrequently accessed data, sc1 provides extremely inexpensive storage. SC1 is designed to deliver the expected throughput performance 99% of the time and has enough I/O credits to support a full-volume scan at the burst rate.

The Cold HDD (sc1) volume type is designed for workloads that require large volumes of data to be accessed infrequently. It offers low-cost storage with throughput performance that is ideal for sequential workloads. Although the initial access time may be slower compared to other EBS volume types, it provides a cost-effective option for storing and accessing large amounts of infrequently accessed data.
(B) is correct.
Throughput Optimized HDD — A low-cost HDD designed for frequently accessed, throughput-intensive workloads.
Cold HDD — The lowest-cost HDD design for less frequently accessed workloads.
(B) is correct.
Throughput Optimized HDD — A low-cost HDD designed for frequently accessed, throughput-intensive workloads.
Cold HDD — The lowest-cost HDD design for less frequently accessed workloads.
Ans: B
Throughput Optimized HDD volumes provide low-cost magnetic storage that defines performance in terms of throughput rather than IOPS. These volumes are ideal for large, sequential workloads such as Amazon EMR, ETL, data warehouses, and log processing. For more information, see Throughput Optimized HDD volumes.
Cold HDD volumes provide low-cost magnetic storage that defines performance in terms of throughput rather than IOPS. These volumes are ideal for large, sequential, cold-data workloads. If you require infrequent access to your data and are looking to save costs, these volumes provides inexpensive block storage. For more information, see Cold HDD volumes.
