DCICN 1.0: Simple Networks

Data center network engineers and learners embarking on a network administration or engineering career who wish to expand their skills in data center networks


Expected Duration
83 minutes

There are various aspects to IP addressing, including calculations for constructing an IP address, classes of IP addresses designated for specific routing purposes, and public versus private IP addresses. After completing this course you will be able to describe how IP addresses and their protocols function. For the Internet and internal networks to function correctly, data must be delivered reliably. In the Open Systems Interconnection (OSI) and TCP/TP models, the transport layer manages the process of reliable data delivery and learning how UDP and TCP function between the network layer and the transport layer provides a more complete understanding of how data is transmitted in a TCP/IP networking environment. In this course, you will learn the function of the transport layer and how UDP and TCP operate. Lastly, you will learn about the elements that govern host-to-host communications and how these elements interact. This course is one of a series in the Skillsoft learning path that covers the objectives for Cisco exam 640-911: Introducing Cisco Data Center Networking.


Network Layer Addressing

  • start the course
  • describe the components of a 32-bit IPv4 address IP
  • describe the IP PDU header
  • describe the concept of dotted decimal notation
  • describe the function of IP address masks
  • compare public and private IP Addresses
  • define the function of DHCP in IP addressing
  • define the function of DNS in IP addressing
  • match common host tools to their descriptions

The TCP/IP Transport Layer

  • describe functions of the transport layer
  • describe major TCP/IP applications
  • sequence the steps of the initialization of a TCP connection to a peer system
  • describe the reasons for and the mechanics of flow control
  • describe the function of windowing
  • describe the use of sequence and acknowledgement numbers

The Packet Delivery Process

  • match Layer 1, 2, and 3 devices to their functions
  • describe Layer 3 addressing
  • describe ARP operations
  • describe the function of the default gateway
  • use common host tools to determine the path between two hosts across a network

Practice: Simple Network Implementation

  • implement a simple host-to-host network
