Each application is defined by an application identifier and can add new command codes and\/or new mandatory AVPs. Adding a new optional AVP does not require a new application.<br \/>\nExamples of Diameter applications:<br \/>\nDiameter Mobile IPv4 Application (MobileIP, RFC 4004)<br \/>\nDiameter Network Access Server Application (NASREQ, RFC 4005)<br \/>\nDiameter Extensible Authentication Protocol (EAP) Application (RFC 4072)<br \/>\nDiameter Credit-Control Application (DCCA, RFC 4006)<br \/>\nDiameter Session Initiation Protocol Application (RFC 4740)<br \/>\nVarious applications in the 3GPP IP Multimedia Subsystem<br \/>\nAll of the other choices presented are true. So Diameter is backwork compatible with Radius (to some extent) but the opposite is false.<br \/>\nReference(s) used for this question:<br \/>\nTIPTON, Harold F. &#038; KRAUSE, MICKI, Information Security Management Handbook, 4th Edition, Volume 2, 2001, CRC Press, NY, Page 38. and <a href=\"https:\/\/secure.wikimedia.org\/wikipedia\/en\/wiki\/Diameter_%28protocol%29\" title=\"External link\" rel=\"nofollow noopener\" target=\"_blank\">https:\/\/secure.wikimedia.org\/wikipedia\/en\/wiki\/Diameter_%28protocol%29<\/a><\/div>\n<p><\/strong><\/span> <\/div>\n","protected":false},"excerpt":{"rendered":"<p>Which of the following statements pertaining to RADIUS is incorrect: A.
