Selected Answer: D
The best option for a software engineer who needs to transfer data over the internet using programmatic access and be able to query the data is: D. GraphQL Here’s why: • GraphQL is a query language for APIs that allows clients to request exactly the data they need, making it ideal for querying and transferring data programmatically over the internet. • It gives the client the power to structure queries and retrieve nested data in a single request, which is efficient and flexible. Why not the others? • A. SQL: Used for querying databases, but not suitable for internet-based programmatic access on its own. • B. Web sockets: Good for real-time, bidirectional communication, but not designed specifically for querying structured data. • C. RPC (Remote Procedure Call): Allows calling functions remotely but is more focused on operations than flexible querying of data.

Selected Answer: B
WebSockets are a communication technology that enables real-time data exchange between a client (such as a web browser) and a server. Unlike the traditional request-response model of HTTP, WebSockets establish a persistent connection, allowing the server to send data to the client at any time, without the client having to make a request.
