Networking exams, especially Cisco tests, can be challenging. If you're scrambling to get in as much study time as possible, you should make excellent use of your Android device by adding these apps to your studying arsenal.

SEE: A (relatively) brief guide to Cisco IT certifications

Networking Exam

For help with your Cisco certs, Networking Exam is the way to go. This app has an easy-to-use (though not modern) interface that gets you quick access to questions for CCNA 200-120, ROUTE 300-101, SWITCH 300-115, TSHOOT 300-135, and CCIE Written 400-101.

All of the the questions are categorized and very detailed (Figure A); more than 90% of the questions have appeared in CCNA, CCNP, and CCIE written exams by Cisco. Networking Exam doesn't allow you to answer the questions in-app, as it is truly a study guide-type application. (Note: The app does include ads.)

Computer Networking Concepts

If you're looking for a solid understanding of networking fundamentals, check out Computer Networking Concepts. This application does a great job of making the Open Systems Interconnection (OSI) model much easier to understand by breaking it up into its constituent layers (application, presentation, session, transport, network, data link, physical).

If you swipe right from the main window, the sidebar will open (Figure B), where you can access the bits and pieces of this app. Tap an entry to read about that particular piece of the networking puzzle.

Network Subnetting

Although more of an actual work tool than a study tool, Network Subnetting can help you calculate subnetting with a few quick taps. A better way to use this tool is as a checker for the work you would do on your own. Do you truly understand the concept of subnetting? You'll soon know with this app.

The interface is simple to use (Figure C) — just enter the necessary details and tap the Subnetting button.

Other apps that will help you understand this very important networking concept include Subnetting Practice Free, Subnetting Questions, and Subnetting Practice.


If you're studying for a CCNA exam, you might want to use CCNA Quiz. This app requires internet connectivity, so take that into consideration, as data usage could apply.

CCNA Quiz offers two modes: Exam and Train. The Train mode allows you take the quizzes and see the correct answers as you go (Figure D).

The Exam mode does not reveal the answers... you're on your own (you can mark a question for later review). With a passing grade of 61%, you can unlock the next section of questions.
