Study enterprise networking subjects that bring dual-stack architecture and virtualization into the same core curriculum. This EnterOne CCNP Enterprise Core course addresses two areas that commonly intersect in enterprise environments: networks supporting more than one IP protocol stack and infrastructure that depends on virtualized resources. It provides a focused training resource for engineers building or refreshing core networking knowledge. CPLL-ENCOR-V1.4 identifies the version 1.4 course. Its scope is centered on Enterprise Core subject matter, with dual-stack architecture and virtualization expressly included. That focus helps distinguish the course from training devoted to a single hardware appliance, interface type, or endpoint technology. Engineers can use it to organize study around the architectural subjects represented in the CCNP Enterprise Core curriculum. The course suits network engineers and architects who need to review how dual-stack networking and virtualization relate to enterprise network design. Its version designation matters when matching a requested course release to an internal learning plan. Choose this course when the required subject coverage is CCNP Enterprise Core, with particular emphasis on dual-stack architecture and virtualization.
