The maximum distance that Cat 5, Cat 5e, Cat 6, and Cat 6a cables can be ran is 100 meters or 328 feet, according to the TIA/EIA standards. This is the maximum length for a cable segment, which is the distance between two devices, such as a switch and a computer, or a router and a printer. If the cable segment exceeds this length, the signal quality may degrade and cause errors or loss of data. Therefore, it is important to measure the cable length before installation and use repeaters or extenders if necessary.

The internal antennas are the components that allow the laptop to receive and transmit wireless signals. If the internal antennas are not connected properly, the laptop may have a weak or no Wi-Fi signal. The technician should verify that the internal antennas are connected to the wireless card and routed correctly inside the laptop case. The internal antennas may have been disconnected or damaged during the screen replacement. The device having the latest OS updates, the wireless device drivers being the latest version, airplane mode being disabled, and the battery being charging are not related to the issue, as they do not affect the physical connection of the internal antennas.

A managed switch is a network device that can be configured to create VLANs (Virtual Local Area Networks), which are logical segments of a network that isolate traffic based on criteria such as function, security, or quality of service. A VLAN can be used to isolate voice traffic on the network, which can improve the performance and security of voice over IP (VoIP) applications. A network tap, a hub, and a DSL filter are not capable of creating VLANs.

The best way to connect the devices is A. Enable pairing.

Pairing is a process that allows two Bluetooth devices, such as a smartphone and a headset, to communicate with each other wirelessly. Pairing creates a secure connection between the devices and allows them to exchange data and audio signals. To pair the devices, the user needs to enable Bluetooth on both devices, make them discoverable, and select the desired device from the list of available devices. The user may also need to enter a PIN code or confirm a passkey to complete the pairing process .

The other options are not the best ways to connect the devices. A hotspot is a feature that allows a smartphone to share its cellular data connection with other devices via Wi-Fi, Bluetooth, or USB. A hotspot can provide internet access to other devices, but it does not allow them to communicate with each other directly. NFC stands for Near Field Communication, which is a technology that allows two devices to exchange data by bringing them close together (usually within 4 cm). NFC can be used to initiate pairing between two Bluetooth devices, but it cannot establish a connection by itself. Synchronization is a process that allows two devices to update and match their data, such as contacts, calendars, photos, or music. Synchronization can be done via Wi-Fi, Bluetooth, USB, or cloud services, but it requires an existing connection between the devices.
