Free 4A0-103: Alcatel-Lucent Multiprotocol Label Switching Exam Questions and Answers
Alcatel-Lucent Multiprotocol Label Switching is exam 4A0-103, part of the Alcatel-Lucent Service Routing Certification programme from Alcatel-Lucent, now part of Nokia. Every exam here carries a 4A0- code, the numbering Alcatel-Lucent used for its carrier service-router track: 4A0-100 is the Scalable IP Networks entry paper, and the routing, MPLS, services, quality-of-service and multicast papers build on it. Nokia acquired Alcatel-Lucent's networking business in 2016 and runs this today as its Service Routing Certification programme, so the ladder these exams sit on — NRS I, then NRS II, then Service Routing Architect — is Nokia's, and the written papers are delivered through Pearson VUE.
