SAA-C03 Question 428
Select 2A company is designing a new cloud-based application that requires high-speed, low-latency access to data for its database system. The application will also need to store large amounts of unstructured data, such as images and videos, for long-term access. Which combination of storage solutions should the company use to meet these requirements?
- A
Amazon EBS for the database and Amazon S3 for storing unstructured data
- B
Amazon EFS for the database and Amazon S3 for storing unstructured data
- C
Amazon S3 for the database and Amazon Glacier for storing unstructured data
- D
Amazon EBS for the database and Amazon Glacier for storing unstructured data
- E
Amazon EFS for the database and Amazon EBS for storing unstructured data
Show answer and explanation
Correct answers: A, D
Explanation
To meet the requirements, the company should use Amazon EBS for the database as it provides high-speed, low-latency block storage suitable for database workloads. For storing large amounts of unstructured data like images and videos, Amazon S3 is an ideal choice due to its scalability, durability, and cost-effectiveness. Amazon Glacier can also be used for archiving unstructured data that is infrequently accessed. Using the right storage types ensures performance, durability, and cost optimization.
- A. Correct.
Correct: Amazon EBS (Elastic Block Store) is a block storage service designed for high-performance, low-latency workloads, making it ideal for databases. Amazon S3 is an object storage service designed for scalability and durability, making it suitable for storing large amounts of unstructured data like images and videos.
- B. Incorrect.
Incorrect: Amazon EFS (Elastic File System) is a file storage service designed for shared access and is not optimized for database workloads. However, Amazon S3 is a good choice for storing unstructured data.
- C. Incorrect.
Incorrect: Amazon S3 is not suitable for database workloads as it is an object storage service and does not support the low-latency and high-performance requirements of databases. Amazon Glacier is designed for long-term archival storage, not for actively accessed unstructured data.
- D. Correct.
Correct: Amazon EBS is suitable for database workloads due to its high-performance and low-latency characteristics. Amazon Glacier is used for long-term storage of infrequently accessed data, which can be a cost-effective solution for archiving unstructured data.
- E. Incorrect.
Incorrect: Amazon EFS is not optimized for database workloads and is better suited for shared file storage. Additionally, Amazon EBS is a block storage service and is not designed for storing large amounts of unstructured data.
