What is the DoD 8570.1 directive?

In 2004, the United States Department of Defense established the 8570.1 Directive that requires all DoD Information Assurance personnel to meet training and certification objectives. It identified two career tracks (Management and Technical), dividing each into three distinct levels. Passing the CompTIA Network+ Certification Exam meets the requirements for Technical Level-I. Other civilian government groups at the state, county and municipal levels have followed the federal government's lead by also establishing these requirements.

Will this course help me prepare for the CompTIA Network+ Certification exam?

Yes! This course prepares you for the CompTIA Network+ Certification exam. You also receive the book, Network+ (N10-004) Exam Cram, to help you prepare. Further, this course is approved by CompTIA as CompTIA Authorized Quality Curriculum (CAQC). This means that the content of this course meets high quality standards and aligns with the CompTIA Network+ Certification exam topics.

Does this course include Network+ exam vouchers or other test preparation materials?

Yes. This course includes a CompTIA Network+ exam voucher and Transcender prep materials to help you prepare for the Network+ Certification exam.

What LAN configurations will be done in this course?

This course provides extensive coverage of cable configuration as well as covering router configuration from the client side. Throughout the configuration, you will be presented with a number of real-world issues to solve, including:

• Critical settings for wireless networks
• Identifying address problems caused by bad masks
• Resolving name resolution problems
• Targeting problem protocol patterns

For more in-depth coverage of routers and router configuration on the server level, you may want to consider Course 364: Switches and Routers: A Comprehensive Hands-On Introduction. That course provides a thorough understanding of the complexities of network router configuration.

How much time is spent on each topic?

What kinds of hands-on exercises does this course include?

Approximately 40 percent of the course consists of hands-on exercises designed to reinforce the configuration and troubleshooting concepts taught in class. Exercises include:

• Testing cables and connections using a cable scanner
• Diagnosing cable and connection configuration to ensure operation
• Analyzing traffic with Wireshark
• Upgrading to a switched network
• Implementing VLANs and 802.1X
• Trouleshooting Virtual Machines
• Setting up a wireless network
