In a previous post, we did this for the first of the two exams – DCICN.

The Old DCICT Exam

Are you interested in squeaking out the old DCICT exam? Its number is 640-916 and your last day to test is April 11, 2017. If you are interested in my training course for this exam, it can be found here at CBT Nuggets until its retirement.

This “old” exam featured these major sections and exam percentages:

1.0 Cisco Data Center Fundamentals Concepts 30%
2.0 Data Center Unified Fabric 20%
3.0 Storage Networking 18%
4.0 Data Center Virtualization 14%
5.0 Unified Computing 17%
6.0 Data Center Network Services 1%

The New DCICT Exam

The new exam features these major sections and exam percentages:

1.0 Unified Computing 25%
2.0 Network Virtualization 17%
3.0 Cisco Data Center Networking Technologies 26%
4.0 Automation and Orchestration 15%
5.0 Application Centric Infrastructure 17%

What was removed from the old exam to the new and what was added? Here are the biggest areas:

Removed:

  • Removed Cisco Data Center Fundamentals topics including SAN have removed
  • Removed network design models
  • Moved and expanded Storage Networking, including SAN, Fibre Channel, and IP Storage topics into 200-150 DCICN
  • Removed Network Services topics such as load balancers, Cisco Application Control Engine (ACE) and Cisco Wide Area Application Services (WAAS)

Added or Changed:

  • Expand virtualization of compute and network
  • Overlay and underlay, control plane and data plane
  • Basics of cloud computing
  • Automation and orchestration of data center infrastructure including Cisco UCS Director basic functions
  • Cisco Application Centric Infrastructure (ACI) including the architecture of an ACI environment, the policy-driven application deployment model, and the ACI logical model

  • Removed Ethernet low-level functionality and added operational roles of data center devices; for example, use cases to deploy various types of physical devices
  • Removed Cisco IOS router topics
  • Removed specifications of platform components as in boot process procedures, passwords, and diagnostics

Added or Changed:

  • Increased breadth of data center networking concepts including First Hop Redundancy Protocols (FHRP), data center networking architectures such as spine-and-leaf designs, unicast and multicast, and authentication, authorization, and accounting (AAA) concepts and filtering
  • Additional focus on high-availability switching concepts, port channel, virtual Port Channel (vPC), and control plane and data plane separation
  • Increased data center storage concepts including Fiber Channel operations and design, IP storage protocols, and moved storage topics from DCICT into DCICN
