Overview of the 4A0-104 Services Architecture Exam
The Nokia 4A0-104 Services Architecture exam mandates mastery of the Nokia Service Router operating system, specifically targeting Network Engineers and Service Architects implementing advanced carrier-grade service infrastructures. Candidates must demonstrate technical proficiency in configuring Layer 2 and Layer 3 VPN services, including VPLS, E-Pipe, I-Pipe, and VPRN deployments. The assessment focuses on the implementation of Provider Backbone Bridging, Ethernet OAM, and integrated service-level agreements within 7750 SR and 7950 XRS platforms. Technical competency requires precise configuration of service distribution points, sap-ingress policies, multi-protocol BGP signaling, and interior gateway protocols necessary to maintain robust, scalable, and high-availability service architectures across MPLS-enabled provider networks.
