AWS Certified Solutions Architect – Associate (SAA-C02) — Question 32

A data science team requires storage for nightly log processing. The size and number of logs is unknown and will persist for 24 hours only.
What is the MOST cost-effective solution?

Answer options

• A. Amazon S3 Glacier
• B. Amazon S3 Standard
• C. Amazon S3 Intelligent-Tiering
• D. Amazon S3 One Zone-Infrequent Access (S3 One Zone-IA)

Correct answer: B

Explanation

The most economical choice for temporary storage of logs that are processed nightly is Amazon S3 Standard, as it offers low-latency access and is designed for frequently accessed data. Amazon S3 Glacier is not suitable due to its retrieval times, while S3 Intelligent-Tiering adds unnecessary complexity and cost for short-term storage needs. Amazon S3 One Zone-IA is also not ideal since it is meant for infrequently accessed data, which does not fit the requirement for nightly log processing.
