About the test
The Network administrator online test assesses knowledge of networking protocols and infrastructure, as well as how to configure networks to ensure security and integrity.
The assessment includes work-sample tasks such as:
- Preventing unauthorized access or misuse of resources.
- Understanding how the Internet works.
- Configuring internal computer networks.
A good network administrator should be familiar with the networking technologies that allow communication between devices and form the backbone of the Internet.

Simple, straight-forward technical testing
TestDome is simple, provides a reasonable (though not extensive) battery of tests to choose from, and doesn't take the candidate an inordinate amount of time. It also simulates working pressure with the time limits.
