A data analytics company needs to process large datasets using Apache Spark. The workload requires instances with a high ratio of memory to vCPU to cache data in memory for fast processing. Which EC2 instance family should they choose?

Answer options:

Compute-optimized (C family)

Memory-optimized (R or X family)

Storage-optimized (I or D family)

General purpose (M family)

How to approach this question

Identify the requirement for 'high ratio of memory to vCPU'. This points to Memory-optimized instances.

Full Answer

B.Memory-optimized (R or X family)✓ Correct

Memory-optimized (R or X family)

Memory optimized instances are designed to deliver fast performance for workloads that process large data sets in memory, such as Apache Spark or in-memory databases.

Common mistakes

Choosing Compute-optimized for 'processing', forgetting that Spark relies heavily on in-memory caching.
