Description

4 credit/unit hours – Four hours of lecture weekly; one term

This course describes the architectures and considerations related to designing, securing, operating, and troubleshooting enterprise networks. Topics include Wide Area Network (WAN) technologies and Quality of Service (QoS) mechanisms used for secure remote access, Software-Defined Networking (SDN), virtualization, and automation concepts that support the digitization of networks. The course is designed to help students prepare for professional careers in the information and communication technology (ICT) field. It also helps prepare individuals seeking to pass the Cisco Certified Network Associate (CCNA) certification exam.

Learning Objectives

Upon completion of this course the student will be able to:

  • Implement standard IPv4 Access Control Lists (ACLs) to filter traffic and secure administrative access;
  • Configure Network Address Translation (NAT) services on the edge router to provide IPv4 address scalability;
  • Explain techniques to provide address scalability and secure remote access for WANs;
  • Explain how to optimize, monitor, and troubleshoot scalable network architectures;
  • Explain how networking devices implement Quality of Service (QoS);
  • Implement protocols to manage the network;
  • Explain how technologies such as virtualization, software defined networking, and automation affect evolving networks; and
  • Utilize network diagrams
