AWS Certified Data Engineer – Associate (DEA-C01) — Question 159

A data engineer needs to use Amazon Neptune to develop graph applications.

Which programming languages should the engineer use to develop the graph applications? (Choose two.)

Answer options

• A. Gremlin
• B. SQL
• C. ANSI SQL
• D. SPARQL
• E. Spark SQL

Correct answer: A, D

Explanation

Gremlin and SPARQL are the appropriate languages for developing graph applications with Amazon Neptune, as they are specifically designed for graph databases. SQL, ANSI SQL, and Spark SQL are not optimized for graph queries and do not support the graph features needed in this context.
