CompTIA Cloud+ (CV0-004) — Question 119

A software engineer needs to transfer data over the internet using programmatic access while also being able to query the data. Which of the following will best help the engineer to complete this task?

Answer options

• A. SQL
• B. Web sockets
• C. RPC
• D. GraphQL

Correct answer: D

Explanation

GraphQL is the best choice for programmatic data access and querying because it allows clients to request only the data they need, reducing the amount of data transferred. SQL is primarily used for database queries, while Web sockets and RPC are more focused on communication protocols rather than data querying capabilities.
