In our last two installments, we started the first parts of a self-test practice assessment based on the CompTIA Network+ (N10-006) certification exam. We looked first at 22 questions about topics beneath the Network Architecture domain, and then at 20 questions on Network Operations.

This time around, we continue to mirror the actual weighting of the CompTIA exam with 24 questions about Troubleshooting. (The final installment in the series will consist of 34 questions that combine the Network Security and Industry Standards, Practices and Network Theory domains.) Good luck!
