Networking Functions

This course is included in our On-demand training solution.


Networking technologies are widely diverse in the basic operations, which include how they are topologically connected. These options impact the nature of the technology and suitability for deployments. In this course, you’ll learn about how the topology of networks impacts their operations. This course is one of a series in the Skillsoft learning path that covers the objectives for the Cisco exam Building Cisco Service Provider Next-Generation Networks Part 1 exam (640-875 SPNGN1). This exam counts toward the CCNA Service Provider certification.

Target Audience

This course is targeted at networking engineers who must interface with Cisco IOS, IOS XR and IOS XE devices. Additionally, those who have a need to understand technologies used in the service provider realm will benefit.



Expected Duration

60 min.
