Questions & Answers PDF P-32 Question: 49 Which statement describes Cross-Origin Resource Sharing (CORS)? A.It allows for signaling-groups to be used by more than one trunk-group. B.It is a W3C specification that allows cross-domain communication from the browser. C.It is making DSP resources available regardless of the originating location of a call. D.It is a network setup by which an Avaya Aura® Media Server (AAMS) can be used by more than one Avaya Aura® Communications Manager (CM). Answer: B Explanation: Cross-origin resource sharing (CORS) is a mechanism that allows restricted resources (e.g. fonts) on a web page to be requested from another domain outside the domain from which the first resource was served. A web page may freely embed cross-origin images, stylesheets, scripts, iframes, and videos. Note on the History of CORS: Cross-origin support was originally proposed by Matt Oshry, Brad Porter, and Michael Bodell of Tellme Networks in March 2004 for inclusion in VoiceXML 2.1 to allow safe cross-origin data requests by VoiceXML browsers. In May 2006 the first W3C Working Draft was submitted. In March 2009 the draft was renamed to "Cross- Origin Resource Sharing" and in January 2014 it was accepted as a W3C Recommendation.
