To answer this question, you need to understand what UDDI is and the Internet standards it uses.
UDDI (Universal Description, Discovery, and Integration) is a directory service that allows businesses to publish and discover web services. It provides a standard way for businesses to describe their services and for other businesses to find and use those services.
UDDI uses several Internet standards, including XML (eXtensible Markup Language), HTTP (Hypertext Transfer Protocol), and DNS (Domain Name System) protocols. These standards are widely used in web development and communication.
Let's go through each option to understand why it is correct or incorrect:
Option A) World Wide Web Consortium (W3C) - This option is incorrect because it only mentions one organization, W3C, which is responsible for developing web standards. It does not mention the other relevant organization, IETF.
Option B) World Wide Web Consortium (W3C) and Internet Engineering Task Force (IETF) - This option is correct because it includes both W3C and IETF. W3C is responsible for developing web standards, including XML, while IETF is responsible for developing Internet protocols, including HTTP and DNS.
Option C) Internet Engineering Task Force (IETF) - This option is incorrect because it only mentions IETF and does not include W3C, which is also involved in developing the relevant Internet standards.
Option D) None of these - This option is incorrect because option B is the correct answer.
The correct answer is B. This option is correct because UDDI uses Internet standards from both W3C (XML) and IETF (HTTP and DNS).
