Examples of standard connectors include which of the following?

The correct choice highlights standard connectors that are utilized for application integration and allowing systems to communicate with one another. SOAP (Simple Object Access Protocol) and REST (Representational State Transfer) are both widely recognized protocols for web services, facilitating data exchange over networks. SOAP is a protocol that defines a set of messaging patterns, while REST is an architectural style that leverages existing and widely known protocols like HTTP.

SAP, in this context, is not a protocol but a software platform that often uses these web services for integration purposes. However, it can be considered part of a broader set of integration methods in enterprise environments, working alongside REST and SOAP to connect various systems and applications.

The other options comprise formats or protocols that have different primary uses. For example, FTP (File Transfer Protocol), HTTP (Hypertext Transfer Protocol), and SMTP (Simple Mail Transfer Protocol) are primarily oriented toward file transfers and internet communication but do not strictly define a standard for web service integration. Similarly, HTML (Hypertext Markup Language), CSV (Comma-Separated Values), and XML (eXtensible Markup Language) are data formats rather than protocols for integration. Lastly, URL, JSON (JavaScript Object Notation), and SQL (Structured Query Language) represent resource identifiers
