• Question 722:

  A company in a large building uses a wireless network for its workstations. After a new company moves into the building on the floor below, the old company's wireless network begins experiencing connectivity Issues. Which of the following is the most likely cause?

  A. External interference

  B. Port flapping

  C. High latency

  D. Limited connectivity

  Correct Answer: A

  Explanation: The most likely cause of the wireless network connectivity issues is A. External interference. External interference is any signal or noise that disrupts or degrades the quality of a wireless network. External interference can come from various sources, such as other wireless networks, cordless phones, microwaves, Bluetooth devices, or electrical appliances. External interference can affect the wireless network performance, reliability, and security, by causing issues such as signal loss, packet drops, latency, or interference. In this scenario, a company in a large building uses a wireless network for its workstations. After a new company moves into the building on the floor below, the old company's wireless network begins experiencing connectivity issues. This could indicate that the new company's wireless network is using the same or overlapping frequency channel as the old company's wireless network, and creating external interference. Wireless networks use radio frequency channels to transmit and receive data, and each channel has a certain bandwidth and range. If two or more wireless networks use the same or overlapping channel, they may interfere with each other and cause congestion or collision. To resolve this issue, the old company's network technician should change the wireless network channel to a different one that is less crowded or more compatible with the wireless network standard. The technician should also check the wireless network settings and features, such as SSID (Service Set Identifier), encryption, authentication, or power level, and adjust them if necessary. The technician should also scan the wireless environment and identify the sources and levels of external interference, and try to avoid or minimize them if possible. For more information about external interference and how to prevent or reduce it, you can refer to the following web search results: [What Is Wireless Interference?], [How to Find the Best WiFi Channel for Your Router], [How to Reduce Wireless Interference].

• Question 723:

  After a technician replaced a printer's ink cartridges, all the print jobs contain shadowing. Which of the following should the technician do first?

  A. Reseat the new ink cartridges.

  B. Run the printer's alignment process.

  C. Replace the fuser assembly.

  D. Install the maintenance kit.

  Correct Answer: B

  Running the printer's alignment process is the first step that a technician should do to fix the shadowing problem on the printouts. Shadowing is a print quality issue that occurs when the printer prints a faint duplicate image of the original text or graphics, usually slightly offset from the original position. This can be caused by a misalignment of the printhead, which is the part of the printer that sprays ink onto the paper. The printer's alignment process is a procedure that adjusts the position and angle of the printhead to ensure that the ink is applied accurately and evenly on the paper. The printer's alignment process can be performed from the printer's menu, the printer's software, or the printer's maintenance tool, depending on the model and type of the printer. The other options are not the best solutions for this problem. Reseating the new ink cartridges may not solve the shadowing issue, unless the cartridges are not properly installed or recognized by the printer. However, this is unlikely to be the case, as the printer would usually display an error message or refuse to print if the cartridges are not compatible or inserted correctly. Replacing the fuser assembly or installing the maintenance kit are more drastic and expensive measures that are usually done when the printer has more serious problems, such as paper jams, smearing, streaking, or fading. The fuser assembly is the part of the printer that heats and melts the toner onto the paper, and the maintenance kit is a set of components that need to be replaced periodically to keep the printer in good condition. These parts are not directly related to the shadowing issue, and replacing them may not fix the problem.

• Question 724:

  A user is connecting to a network via a Bluetooth hot-spot. Which of the following best describes this type of network?

  A. SAN

  B. WAN

  C. LAN

  D. PAN

  Correct Answer: D

  The correct answer is D. PAN. A PAN, or Personal Area Network, is a type of network that connects devices within a short range, usually less than 10 meters, and is used by an individual. A PAN can be wireless or wired, and it can enable data transmission between devices without requiring an internet connection. A PAN can also be connected to a LAN or a higher level network, where one device acts as a gateway. A Bluetooth hotspot is an example of a wireless PAN, where a device such as a smartphone or a laptop can create a network with other Bluetooth-enabled devices nearby. A Bluetooth hotspot can allow devices to share files, access the internet, or use peripherals such as printers or speakers. A SAN, or Storage Area Network, is a type of network that connects storage devices such as hard disks, tape drives, or optical drives to servers. A SAN provides high-speed data transfer and access to large amounts of data. A SAN is usually used in data centers or enterprises that need to store and manage huge volumes of data. A WAN, or Wide Area Network, is a type of network that connects devices over a large geographical area, such as across cities, countries, or continents. A WAN can use different technologies and media to transmit data, such as fiber-optic cables, satellite links, or radio waves. A WAN can also consist of multiple LANs or other types of networks. The internet is the largest example of a WAN. A LAN, or Local Area Network, is a type of network that connects devices within a limited area, such as within a building or a campus. A LAN can use wired or wireless technologies to transmit data, such as Ethernet cables, Wi-Fi routers, or switches. A LAN can enable devices to share resources, such as printers, scanners, or files.

• Question 725:

  A technician is creating a new RAID array for a customer After interviewing the customer, the technician decides to implement a RAID array of striping without parity. Which of the following reasons would lead the technician to choose striping without parity instead of striping with parity?

  A. Uptime is the customer's biggest concern

  B. Speed is the most important consideration.

  C. Redundancy and speed are equally important

  D. Available storage space needs to be maximized

  Correct Answer: B

  Explanation: Speed is the most important consideration. Striping without parity, also known as RAID 0, is a RAID configuration that splits data across multiple disks without any redundancy. This improves the performance of read and write operations, as multiple disks can work in parallel. However, this also increases the risk of data loss, as any disk failure will result in losing all data on the array. Therefore, striping without parity is suitable for situations where speed is prioritized over reliability. According to the CompTIA Core1 objectives, one of the advantages of RAID 0 is increased speed. A research paper on RAID performance also confirms that RAID 0 has the highest throughput among all RAID levels.

• Question 726:

  A user's smartphone loses its charge rapidly. The user also notices that the phone feels thicker than it was when it was new. Which of the following is the most likely cause of the issue?

  A. Bad battery

  B. Malware infection

  C. Damaged charge port

  D. Poor connectivity

  Correct Answer: A

  The user's smartphone is losing its charge rapidly and feels thicker than it was when new. Both of these symptoms point towards a bad battery. A bad battery loses its ability to hold a charge, leading to rapid draining. Additionally, a bad battery can physically swell, which explains why the phone feels thicker. Malware infection, damaged charge port, and poor connectivity are unlikely causes for both the rapid draining and the increased thickness.

• Question 727:

  Given the following output from a cable tester:

  ===================

  = Open

  =12345678=

  =12 45 78=

  ===================

  Which of the following tools should the technician use to resolve this issue? (Select two).

  A. Loopback plug

  B. Network tap

  C. Toner probe

  D. Crimper

  E. Punchdown tool

  F. Wi-Fi analyzer

  Correct Answer: DE

  The output from the cable tester indicates that there is an open fault in the cable, which means that one or more of the wires in the cable are not connected properly or are broken. The open fault affects the wires 3, 4, and 6, which are used for transmitting and receiving data in Ethernet networks. The open fault can cause network connectivity issues, such as no link, slow speed, or packet loss12. To resolve this issue, the technician should use a crimper and a punchdown tool, which are tools that are used to attach connectors to cables or wires to patch panels. A crimper is a tool that squeezes or crimps a connector, such as an RJ- 45, to the end of a cable, ensuring that the wires are securely inserted into the pins of the connector. A punchdown tool is a tool that pushes or punches a wire into a slot on a patch panel, creating a connection between the wire and the panel. Both tools can be used to fix or replace the faulty wires or connectors that cause the open fault12. The other options are not as effective or relevant as a crimper and a punchdown tool. A loopback plug is a tool that is used to test the functionality of a network port or device, by sending and receiving signals from the same port or device. A loopback plug can help diagnose network problems, such as faulty ports or devices, but it cannot fix the open fault in the cable12. A network tap is a tool that is used to monitor or capture network traffic, by creating a copy of the data that passes through a network link. A network tap can help analyze network performance, security, or troubleshooting, but it cannot fix the open fault in the cable12. A toner probe is a tool that is used to trace or identify a cable or wire, by sending and detecting an audible tone along the cable or wire. A toner probe can help locate or label network cables or wires, but it cannot fix the open fault in the cable12. A Wi- Fi analyzer is a tool that is used to scan or measure wireless networks, by displaying information such as signal strength, channel, encryption, etc. A Wi-Fi analyzer can help optimize or troubleshoot wireless networks, but it cannot fix the open fault in the cable12.

• Question 728:

  A user with an older laptop is unable to connect to the office network after new access points were installed. The user confirms that from home the laptop can connect wirelessly to the network. Which of the following should the user to do to quickly resolve the issue?

  A. Connect a new USB adapter.

  B. Install a new SSD

  C. Connect a new biometric device.

  D. Install a new Bluetooth card.

  Correct Answer: A

  A USB adapter is a device that can plug into a USB port on a laptop and provide wireless connectivity to a network. A USB adapter can support different wireless standards, such as 802.11a, 802.11b, 802.11g, 802.11n, or 802.11ac. A USB adapter can also support different wireless frequencies, such as 2.4 GHz or 5 GHz. In this case, the user with an older laptop may not be able to connect to the office network after new access points were installed because the laptop's built-in wireless card does not support the same wireless standard or frequency as the new access points. For example, if the new access points use 802.11ac and 5 GHz, and the laptop's wireless card only supports 802.11g and 2.4 GHz, the laptop will not be able to communicate with the access points. To quickly resolve this issue, the user should connect a new USB adapter that supports the same wireless standard and frequency as the new access points. This way, the user can bypass the laptop's wireless card and use the USB adapter to connect to the office network wirelessly. Reference: CompTIA A+ Core 1: Cable Types and Connectors

• Question 730:

  A customer's Windows tablet PC was dropped and is no longer responding to touch input on the left half of the screen. The screen protector has several scratches. but the glass is not broken. Which of the following should a technician do to diagnose the issue?

  A. Test the digitizer

  B. Update the device drivers.

  C. Replace the damaged screen protector

  D. Perform a factory reset.

  Correct Answer: A

  Explanation: The digitizer is the component that converts the touch input into electrical signals that are processed by the tablet. If the digitizer is damaged or malfunctioning, it may not register the touch input correctly or at all. The technician can test the digitizer using a diagnostic tool or by replacing it with a known good one. Updating the device drivers, replacing the damaged screen protector, or performing a factory reset are unlikely to fix the issue, as they do not address the hardware problem.
