Hi,
Welcome to Microsoft Q&A community forum!
You can use wired mouse and keyboard on your exam.
you can also check your system compatibility here at this link
https://home.pearsonvue.com/op/OnVUE-technical-requirements
Thoroughly review these technical requirements to ensure your system is compatible with the OnVUE online testing software. If your system does not meet the requirements and causes a problem during the exam, you will be responsible for any costs associated with rescheduling your exam.
NOTE: The two most frequent causes of technical issues are (1) testing on an employer-issued computer and (2) unreliable internet connections. Firewalls or security settings from employer-issued computers may prevent the OnVUE software from operating properly. Unreliable internet connections (e.g., wireless networks, hotels, VPNs, mobile hotspots) may interrupt connectivity. For these reasons, we strongly recommend using a personal computer (i.e., one not issued by your employer) and a wired, ethernet connection.
