  Explanation

  The Official CompTIA A+ Core 1 and Core 2 Student Guide (Exams 220- 1001 and 220-1002) | 193 Protected content. If you encounter an error that indicates unauthorized content or an HDCP error: DVI, HDMI, DisplayPort, and Thunderbolt all provide support for the Digital Rights Management (DRM) mechanism High-bandwidth Digital Content Protection (HDCP). HDCP allows a content source (such as a Blu-ray disc) to disable itself if the display adapter and monitor and/or speaker system do not support HDCP and fail to authenticate themselves with the playback source. There have been various iterations of HDCP (at time of writing the current version is 2.2) and backward- compatibility can be problematic as authentication may fail between devices that support different versions of the standard.

• Question 683:

  A salesperson is using a weather application on a mobile device. The application appears to be draining the device's battery very quickly. Which of the following is the BEST action for the salesperson to take in order to view weather forecasts while travelling?

  A. Enable the GPS service to ensure accurate location detection.
  B. Manually enter office locations in the weather application.
  C. Configure less frequent location checks using cellular location services.
  D. Use the offices' Wi-Fi IP addresses as the geolocation mechanism.
  C. Configure less frequent location checks using cellular location services.

  ---

  Explanation

  The weather application could be draining the battery quickly because it is constantly checking for the user's location using cellular location services. To resolve this issue, the salesperson can configure the weather application to check for location less frequently, or turn off location services when not needed. This way, the application will not be constantly using the battery by checking for location updates, thus extending the device's battery life.

• Question 684:

  A laser printer, which is located in a large office, has a leaky toner cartridge. Some toner spilled into the printer when the cartridge was removed.

  Which of the following is the best way to clean up the toner?

  A. Magnetic duster
  B. ESD-safe vacuum
  C. Compressed air
  D. Damp cloth
  B. ESD-safe vacuum

  ---

  Explanation

  The best way to clean up the toner that spilled into the printer is to use an ESD-safe vacuum. An ESD-safe vacuum is a special type of vacuum that has a filter that traps toner particles and prevents them from escaping into the air. An ESD-safe vacuum also has a grounding wire that prevents static electricity from building up and damaging the printer's components. Toner is electrically conductive and can cause short circuits or sparks if it contacts sensitive parts of the printer. Therefore, using an ESD-safe vacuum is the safest and most effective method to remove the toner from the printer. Other methods, such as a magnetic duster, compressed air, or a damp cloth, are not recommended for cleaning up toner spills. A magnetic duster is a device that uses a magnet to attract toner particles, but it can also damage the printer's components that rely on magnetism, such as the drum or the fuser. Compressed air can blow the toner around and create a cloud of dust that can be harmful to breathe or contaminate other parts of the printer. A damp cloth can smear the toner and make it harder to remove, as well as cause corrosion or rust on the printer's metal parts.

• Question 685:

  Which of the following protocols provides the fastest bandwidth?

  A. 802.11a
  B. 802.11ac
  C. 802.11ax
  D. 802.11n
  C. 802.11ax

  ---

  Explanation

  The 802.11ax protocol, also known as Wi-Fi 6, provides the fastest bandwidth among the options listed. It can achieve up to 10 Gbps of data transfer rate, using technologies such as OFDMA, MU-MIMO, and 1024-QAM. The 802.11ac protocol, or Wi-Fi 5, is the second fastest, with a maximum of 3.46 Gbps, followed by the 802.11n protocol, or Wi-Fi 4, with a maximum of 600 Mbps. The 802.11a protocol is the slowest, with a maximum of 54 Mbps

• Question 688:

  A user's desktop PC shuts down suddenly every few hours. A technician smells burning coming from the back of the PC where it is connected to the wall socket.

  Which of the following should the technician do first to identify the issue?

  A. Check that the power cable is not damaged.
  B. Ensure the power supply is set to the correct voltage.
  C. Verify the power supply is outputting adequate wattage.
  D. Inspect the power supply fan for debris.
  A. Check that the power cable is not damaged.

  ---

  Explanation

  If a desktop PC shuts down suddenly and there is a burning smell coming from the area where it is connected to the wall socket, the first step should be to check that the power cable is not damaged. A damaged power cable can cause electrical shorts or overheating, leading to sudden shutdowns and a burning smell. Inspecting the power cable for fraying, cuts, or other damage can help identify if it is the source of the problem.

  Explanation

  A technician is working on a help desk ticket for a user who wants the filament replaced in a 3-D printer. To remove the old filament and load the new one, the technician should preheat the nozzle to melting temperature. After the nozzle is heated, the technician should withdraw the filament and remove the spool. Then, cut a sharp angle on the end of the new strand, and push it along until resistance is felt.
