Free A+ practice question with explanation
This original learning scenario demonstrates the reasoning to practice. It is not an official or recalled exam item.
A workstation reports no network connection after its desk was moved. Other workstations still work. What should you check first?
- Replace the workstation motherboard.
- Check that the Ethernet cable is seated at both ends and inspect link indicators.
- Reinstall the operating system.
Show answer and explanation
Answer: B. The desk move provides a useful starting point: inspect the local physical connection and record the link state. A motherboard replacement or OS reinstall makes a much larger change before checking a simple, relevant cause. If the link is present, continue with addressing and the network path rather than assuming the cable was the entire problem.
Turn the question into a practical exercise
Sketch a workstation, wall socket, patch panel and switch. Label each connection. Write the checks you would perform and the evidence you would record before asking another team to investigate.
Write down the symptom, the evidence you would collect, the next action and the condition that would make you escalate. Label a paper exercise as a simulation; do not present it as work performed on a live system.
What should you review next?
Hardware identification, operating systems, user support and a documented troubleshooting process. After a practice session, group mistakes by concept and explain the right answer in your own words. Review the topic again after a gap before trying a timed mock. Repeated exposure to the same question can improve recall without demonstrating understanding.

Does a high practice score mean I am ready?
A score is one signal. Explain unfamiliar scenarios, demonstrate the practical tasks and compare your study coverage with the certification vendor’s current objectives. CertNivo does not issue the vendor certification or guarantee an exam outcome.
