Exam AWS Certified Developer - Associate DVA-C02 topic 1 question 295 discussion

Exam question from Amazon's AWS Certified Developer - Associate DVA-C02
Question #: 295
Topic #: 1
[All AWS Certified Developer - Associate DVA-C02 Questions]

A company has a social media application that receives large amounts of traffic. User posts and interactions are continuously updated in an Amazon RDS database. The data changes frequently, and the data types can be complex. The application must serve read requests with minimal latency.

The application's current architecture struggles to deliver these rapid data updates efficiently. The company needs a solution to improve the application's performance.

Which solution will meet these requirements?

  • A. Use Amazon DynamoDB Accelerator (DAX) in front of the RDS database to provide a caching layer for the high volume of rapidly changing data.
  • B. Set up Amazon S3 Transfer Acceleration on the RDS database to enhance the speed of data transfer from the databases to the application.
  • C. Add an Amazon CloudFront distribution in front of the RDS database to provide a caching layer for the high volume of rapidly changing data.
  • D. Create an Amazon ElastiCache for Redis cluster. Update the application code to use a write-through caching strategy and read the data from Redis.

D Cloud Front is generally used to distribute static content such as images, stylesheets, and scripts. CloudFront is not typically used for caching database queries or dynamic data directly from databases like RDS.

This option is the most suitable for the described scenario. Amazon ElastiCache for Redis can act as a high-performance, in-memory data store and cache, which is ideal for applications that require fast access to data. Implementing a write-through caching strategy ensures that data is written to the cache and the primary data store (RDS) simultaneously, keeping the cache up to date. Reading data from the cache can significantly reduce latency and the load on the RDS database, making it an optimal solution for applications with high read demand.

R. Utilice Amazon DynamoDB Accelerator (DAX) frente a la base de datos RDS para proporcionar una capa de almacenamiento en caché para el gran volumen de datos que cambian rápidamente. Al utilizar Amazon DynamoDB Accelerator (DAX) frente a la base de datos RDS, se puede proporcionar una capa de almacenamiento en caché para el gran volumen de datos que cambian rápidamente. DAX mejora el rendimiento de las consultas de lectura al almacenar en caché los resultados de las consultas más frecuentes, lo que reduce la latencia y mejora la capacidad de respuesta de la aplicación. Es importante tener en cuenta que DynamoDB Accelerator (DAX) es una opción eficiente para mejorar el rendimiento de aplicaciones que requieren un acceso rápido a datos que cambian con frecuencia, como en el caso de una aplicación de redes sociales.
