RDP stands for Remote Desktop Protocol and it is a protocol that allows a user to remotely access and control another computer over a network. A technician can use RDP to assist a user who is in a different building but on the same network by connecting to the user’s computer and viewing their screen, keyboard, and mouse. AAA, SSH, and VPN are not protocols that can be used to assist a user with a program feature.

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:

Screen-sharing software is a tool that allows a technician to remotely view and control a user’s screen over the internet. It can be used to troubleshoot issues with accessing an online share, as well as other problems that require visual inspection or guidance. Secure shell (SSH) is a protocol that allows remote access and command execution on another device, but it does not allow screen-sharing. Virtual private network (VPN) is a protocol that creates a secure tunnel between two devices over the internet, but it does not allow remote troubleshooting. File transfer software is a tool that allows transferring files between two devices over the internet, but it does not allow screen-sharing. Verified References:

Device compatibility is an advantage of using WPA2 instead of WPA3. WPA2 is the previous version of the Wi-Fi Protected Access protocol, which provides security and encryption for wireless networks. WPA3 is the latest version, which offers improved security features, such as stronger encryption, enhanced protection against brute-force attacks, and easier configuration. However, WPA3 is not backward compatible with older devices that only support WPA2 or earlier protocols. Therefore, using WPA3 may limit the range of devices that can connect to the wireless network. Connection security, encryption key length, and offline decryption resistance are advantages of using WPA3 instead of WPA2. References:
