 HDMI and VGA are the connectors that should be available in the conference room to ensure everyone can use the conference room projectors. HDMI and VGA are types of video connectors that are used to connect a video source, such as a laptop, to a video output, such as a projector. HDMI stands for High-Definition Multimedia Interface, which is a digital connector that can transmit high-quality video and audio signals over a single cable. VGA stands for Video Graphics Array, which is an analog connector that can transmit standard-definition video signals over a 15-pin cable. HDMI and VGA are common video connectors that are found on old and new laptops, respectively. Having both HDMI and VGA connectors in the conference room can ensure compatibility and connectivity for different laptops and projectors. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 40.

To track system messages and alerts effectively and observe trends over time, the best tool to use are system logs. Logs record events and data during the operation of a system or software application, allowing a network administrator to review historical data, spot patterns, or identify recurrent issues. This is essential for troubleshooting, auditing, and maintaining the overall health of the IT infrastructure.

References:The importance of using logs for monitoring and tracking system activities is covered under the "Networking and Connectivity" section of CompTIA IT Fundamentals, as well as various sections discussing system maintenance and troubleshooting across CompTIA certification study materials.

Documenting lessons learned is the last step of the troubleshooting methodology, which is a systematic approach to solving problems. Documenting lessons learned involves recording the problem, the solution, and the process that was followed to resolve the problem. This can help prevent future occurrences of the same or similar problems, improve the troubleshooting skills of the technician, and provide a reference for other technicians who may encounter the same or similar problems. Documenting lessons learned would be the next troubleshooting step the technician should do after verifying full system functionality. Determining if anything has changed, establishing a theory of probable cause, and duplicating the problem are not steps that follow verifying full system functionality in the troubleshooting methodology. References: CompTIA IT Fundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 9: Troubleshooting and Operational Procedures, page 341.

NFC (Near Field Communication) is a wireless technology that allows devices to communicate and exchange data within a short range, typically a few centimeters. NFC is commonly used for tap to pay transactions, where a customer can use a contactless card or a smart device (such as a smartphone or a smartwatch) to make payments by tapping or hovering over a compatible terminal. NFC is different from other wireless technologies, such as Wi-Fi, IR (Infrared), and Bluetooth, because it does not require pairing, authentication, or network access to work. NFC is also faster, more secure, and more convenient than other payment methods, such as inserting or swiping a card. References: CompTIA IT Fundamentals (ITF+) Certification Guide, page 25; What is Tap to Pay and How Does It Work?
