• Question 592:

  A technician is troubleshooting a wireless network issue. The users are all connected to the network, but the throughput is slow, and connections often drop. Which of the following should the technician check first?

  A. Encryption cipher

  B. Channel interference

  C. Number of connected devices

  D. Antenna type

  Correct Answer: B

  The first thing that the technician should check when troubleshooting a wireless network issue with slow throughput and frequent connection drops is the channel interference. Channel interference is a common cause of poor Wi-Fi performance, as it occurs when multiple wireless networks or devices use the same or overlapping frequency bands, resulting in signal degradation, congestion, or collision. Channel interference can affect both 2.4 GHz and 5 GHz networks, but it is more likely to happen on the 2.4 GHz band, as it has fewer and narrower channels than the 5 GHz band. To check for channel interference, the technician can use a Wi-Fi analyzer tool, such as the ones found in the web search results123, to scan the wireless environment and identify the best channel to use for the network. A Wi-Fi analyzer tool can display various information, such as the network name (SSID), signal strength (RSSI), channel number, frequency, bandwidth, and security type. The technician can look for the following indicators of channel interference: High network density: If there are many wireless networks or devices in the vicinity, they may compete for the same or adjacent channels, causing interference and congestion. The technician can look for the number of networks or devices on each channel and avoid the crowded ones. Channel overlap: If there are wireless networks or devices that use the same or partially overlapping channels, they may interfere with each other and degrade the signal quality. The technician can look for the channel width and frequency of each network and avoid the overlapping ones. For example, on the 2.4 GHz band, the technician should use only the non-overlapping channels 1, 6, and 11, and avoid the channels in between. Signal interference: If there are other sources of electromagnetic radiation or noise that operate on the same or similar frequency bands as the wireless network, they may interfere with the wireless signals and cause distortion or loss. The technician can look for the signal strength and quality of each network and avoid the ones that are weak or noisy. For example, some common sources of signal interference are microwave ovens, cordless phones, Bluetooth devices, or baby monitors. To fix the channel interference issue, the technician can try the following solutions: Change the channel of the wireless network: The technician can use the Wi-Fi analyzer tool to find the least congested and most optimal channel for the network, and then change the channel settings on the router or the access point. The technician should also consider using the 5 GHz band instead of the 2.4 GHz band, as it offers more and wider channels and less interference. Relocate the router or the access point: The technician can move the router or the access point to a different location, away from potential sources of interference or obstacles that may block or weaken the wireless signals, such as walls, furniture, or metal objects. The technician should also place the router or the access point in a central and elevated position, to provide better coverage and signal quality for the network. Upgrade the router or the access point: The technician can replace the router or the access point with a newer and more advanced model, that supports the latest Wi-Fi standards, such as Wi-Fi 6 (802.11ax) or Wi-Fi 5 (802.11ac). These standards offer higher data rates, lower latency, and better performance in dense and noisy environments, compared to the older standards, such as Wi-Fi 4 (802.11n) or Wi-Fi 3 (802.11g).

• Question 599:

  Which of the following network types is used for pairing a Bluetooth device to a smartphone?

  A. PAN

  B. WAN

  C. LAN

  D. MAN

  Correct Answer: A

  Explanation: A PAN, or Personal Area Network, is the network type that is used for pairing a Bluetooth device to a smartphone. A PAN is a network that connects personal devices, such as phones, tablets, laptops, headphones, speakers, or printers, over a short distance, usually less than 10 meters or 33 feet. A PAN can use wireless technologies, such as Bluetooth, Wi-Fi, or infrared, to enable communication and data exchange between the devices. A Bluetooth PAN, also known as a piconet, can consist of up to eight devices, one of which acts as the master and the others as slaves. The master device initiates the pairing process with the other devices and controls the data transmission. The devices use radio waves in the 2.4 GHz frequency band to communicate with each other. Bluetooth is a low-power, low-cost, and secure technology that is widely used for creating PANs.

• Question 600:

  A team is having Issues With paper jams on a printer that the team shares With other teams. The team that IS having Issues prints legal-sized documents, and the other teams print letter-sized documents. Which of the following is most likely the issue?

  A. Worn rollers

  B. Page orientation

  C. Tray settings

  D. Multipage misfeed

  Correct Answer: C

  Explanation: The most likely issue is C. Tray settings.

  Tray settings are the configuration options that tell the printer what type and size of paper is loaded in each tray. If the tray settings do not match the actual paper loaded, it can cause paper jams, misalignment, or incorrect printing. For example, if the printer expects letter- sized paper (8.5 x 11 inches) but the tray contains legal-sized paper (8.5 x 14 inches), the printer may try to pull more paper than it needs, resulting in a jam. To fix this issue, the team should check and adjust the tray settings according to the paper they are using. They should also make sure that the paper is loaded correctly and not overfilled or mixed with different sizes or types of paper. Some printers have a manual feed option that allows users to select the paper size and type before printing, which can prevent paper jams from occurring.
