CCNA Practice Questions

The CCNA Official Cert Guides come with practice questions. You can use some of those practice questions at Safari (O’Reilly Online), and for others you must purchase the book(s). In particular:

  • The Safari offering includes all four CCNA Exam banks found in some of the books.
  • The Premium Edition eBook products from Cisco Press, namely the CCNA Vol 2 Premium Edition and the CCNA Library Premium Edition, include those same four CCNA exam banks.
  • The CCNA Vol 1 and CCNA Vol 2 books include other exam banks: one with all the questions from the chapter pre-quizzes, one with part review questions, and others that cover only the content in that book but not the other volume.
  • The print books include two exam banks, rather than four, for the general question types.

Packet Tracer and Labs

Cisco Packet Tracer

Cisco Packet Tracer (PT) has a couple of great features as a CCNA learning tool. In particular, it’s free, and it supports many of the CLI commands you need to know for CCNA. To learn more:

Wendell's Other Lab and Study Content

Wendell’s CCNA Blog: A large variety of content about CCNA Content from over the last eight years.

Config Labs for CCNA 200-301: Short configuration exercises for which you do not even need a simulator – just write your config on paper or type in an editor.

Packet Tracer Labs for the Books’ Examples: The blog has a series of posts about how to use Cisco Packet Tracer to re-create examples from the books. Each post matches a book chapter, with a goal of helping you decide which examples can be reasonably done in PT and which ones are probably too difficult to re-create in PT for various reasons.

Pearson Network Simulator: Think of it as like Packet Tracer, but with hundreds of built-in lab exercises, for usually around $100 US.

IP Subnetting

IP Subnetting Resources for CCNA

IP Subnetting from Beginning to Mastery LiveLessons (Recorded Video Course): A video course about IP Subnetting. 1/3 explanation, 1/3 problem walkthroughs, 1/3 practice for you.

IP Subnetting from Beginning to Mastery LiveLessons (Live Online Course): An interactive live course on the most important parts of subnetting, with lab exercises during class. Come to class, learn subnetting, practice, and get answers to your questions.
