This module describes the architectures and considerations related to designing, securing, operating, and troubleshooting enterprise networks. This module covers wide area network (WAN) technologies and quality of service (QoS) mechanisms used for secure remote access. The module also introduces software-defined networking, virtualization, and automation

concepts that support the digitalization of networks. The following Key areas are covered:



Implementation of VLANs and trunking in a switched network

Troubleshooting inter-VLAN routing on Layer 3 devices

Implementing single-area OSPFv2 in both point-to-point and broadcast multiaccess networks

How ACLs are used as part of a network security policy

Configuration of NAT services on edge routers to provide IPv4 address scalability

WAN access technologies to satisfy business requirements

VPNs and IPsec secure site-to-site and remote access connectivity

Networking devices and implementation to QoS

Protocols to manage networks

Scalable network architectures

Purpose and characteristics of network virtualization

Network Automation through application programming interfaces (APIs)

Written online test – A written test covering topics of practical networking technology application, and comparison of technologies in relation to given scenarios (Learning Outcomes 1, 2, and 4)

Practical lab assessment - A practical assessment for the design, implement and testing of a given network case study (Learning outcomes 1 and 4).

There will be six weekly one-hour lectures/sessions to supplement on-line material for the first 4 – 6 weeks. There after self-directed learning using online material will take place. Students will be given a guided study plan to support personal studies’ planning.
