For an inexpensive file server to share photos and videos while avoiding complicated licensing, the technician should recommend:
* Linux: Linux is a free and open-source operating system that is ideal for setting up a file server. It offers robust file-sharing capabilities with minimal licensing complications.
* Chrome OS: Designed primarily for lightweight, web-based tasks and not ideal for a file server.
* macOS: Requires Apple hardware and involves more complex licensing compared to Linux.
* Windows: While capable of being a file server, Windows may involve licensing fees, particularly for server editions.

After implementing a change authorized by the change advisory board (CAB), the technician should document the date and time of change as part of the post-implementation review. This helps to track the change history, verify the success of the change, and identify any issues or incidents caused by the change1. Documenting the purpose of the change, the risk level, and the findings of the sandbox test are all part of the pre-implementation activities that should be done before submitting the change request to the CAB2.
