Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 1000 discussion

Question says, "Apps must be able to retrieve frequently accessed data with low latency" so we go with cached volumes. We'd have chosen the stored volumes if question was about low-latency access to the entire dataset.

B- Cached volumes store only the most frequently accessed data on-premises, while the full dataset is stored in Amazon S3. This ensures low-latency access to frequently accessed data while leveraging the scalability and durability of S3 for the full dataset. C - Stored volumes store the entire dataset on-premises and asynchronously back it up to AWS. This option does not address the company’s requirement for limited on-premises storage capacity.

choose store volume mode

Block storage use volume gateway, low latency use store volumes.

Respuesta correcta B . Baja latencia = Elastic Cache . A , C y D no cumplen un acceso con baja latencia ( descartados ) .
