About the test

The System and Network Administration online test assesses knowledge of setting up and maintaining computer systems and networks.

The assessment includes work-sample tasks, such as:

  • Configuring IP addresses on devices in networks using DHCP.
  • Understanding network protocols.
  • Preparing backup procedures to prevent data loss.

A good system and network administrator needs to have knowledge of maintenance and reliable operation of system software, hardware, servers, and network infrastructure.

Decorative quote

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.
