The correct answer is A. Document the date and time of change. After implementing a change, the technician should document the date and time of change in the change log or record. This helps to track the change history, monitor the change performance, and identify any issues or incidents related to the change. Documenting the date and time of change is also a good practice for auditing and compliance purposes.

Documenting the purpose of the change (B) and the risk level © are steps that should be done before implementing the change, not after. These are important information that help to justify, prioritize, and plan the change. The purpose of the change should explain why the change is needed and what benefits it will bring to the organization. The risk level should assess the potential impact and probability of the change causing any problems or disruptions to the business.

Documenting the findings of the sandbox test (D) is also a step that should be done before implementing the change, not after. A sandbox test is a way of testing the change in an isolated environment that mimics the production environment. This helps to verify that the change works as expected and does not cause any errors or conflicts with other systems or processes. The findings of the sandbox test should be documented and reviewed by the change advisory board (CAB) before approving the change for implementation.

LAN is the most likely option to be impacted in this situation. LAN stands for Local Area Network, and it is a network that connects devices within a limited area, such as a building or a campus. Installing high-definition IP videoconferencing equipment in all classrooms would require a high bandwidth and reliable LAN infrastructure to support the video and audio transmission. The LAN would also need to be configured with proper security, quality of service, and multicast protocols to ensure the optimal performance of the videoconferencing system. SAN, GPU, and PAN are not directly related to this scenario. SAN stands for Storage Area Network, and it is a network that provides access to consolidated storage devices. GPU stands for Graphics Processing Unit, and it is a hardware component that handles graphics rendering and computation. PAN stands for Personal Area Network, and it is a network that connects devices within a short range, such as Bluetooth or infrared. References:

AutoPlay is a feature that automatically runs programs or files when a removable media device, such as a flash drive, is plugged in. This can be exploited by malware authors who place malicious files on flash drives that execute automatically when inserted into a computer. Turning off AutoPlay can prevent this type of incident by requiring the user to manually open or run files from removable media devices. Disabling UAC (user account control), restricting local administrators and enabling UPnP (universal plug and play) are not effective ways to prevent this type of incident.
