  Explanation

  Contactless payments commonly use NFC (Near Field Communication) technology. NFC allows two devices to communicate wirelessly when they are brought close together, typically within a few centimeters. Contactless payment systems, such as Apple Pay, Google Wallet, and Samsung Pay, use NFC to securely transmit payment information between a smartphone or smartwatch and a payment terminal. While IoT devices, inventory tracking, and tethering may also use NFC, contactless payments are the most common use case.

• Question 493:

  A user keeps getting an error message when trying to print a letter. The printer is normally used to print cards and invitations. The user tries printing from a different computer, but the issue persists.

  Which of the following should the user do to resolve the issue?

  A. Print fewer pages.
  B. Print on card stock
  C. Replace the rollers.
  D. Change the paper tray setting.
  D. Change the paper tray setting.

  ---

  Explanation

  If a printer is set to use a special tray (for cards/invitations) but a different type of print job is attempted (like a letter), a paper tray setting mismatch can cause errors. Changing the tray setting to match the print media resolves the issue.

  From CompTIA A+ 220-1101 Official Study Guide, Objective 4.3 -Troubleshooting printers:

  "If print jobs fail when media type changes, verify and adjust the paper tray settings to match the required output."

• Question 496:

  A projector has been shutting down after 30 minutes of use, and it has a strange smell. The technician confirms the power source is not the cause of the issue.

  Which of the following steps should the technician take next to resolve this issue?

  A. Replace the bulb
  B. Check the projector configuration.
  C. Clean the filter
  D. Adjust the gamma settings.
  C. Clean the filter

  ---

  Explanation

  Reasoning: Projectors have air filters that prevent dust from entering the internal components. A clogged filter can cause the projector to overheat, resulting in shutdowns and even strange smells due to overheating components. Cleaning the filter is a standard troubleshooting step when projectors exhibit overheating symptoms.

  Why the Other Options Are Incorrect:

  Option A: Replace the bulb:

  While a failing bulb may eventually cause issues, it would not typically result in a strange smell or repeated shutdowns after a fixed period. Bulb issues usually manifest as dim or flickering images.

  Option B: Check the projector configuration:

  Configuration settings, such as resolution or input options, would not cause overheating or shutdowns. This option does not address the described symptoms.

  Option D: Adjust the gamma settings:

  Gamma settings affect display brightness and contrast but have no impact on overheating or strange smells.

  Practical Example:

  Dust accumulation in projectors is a common issue, especially in environments with poor air circulation. A clogged filter causes restricted airflow, leading to overheating and automatic shutdowns to protect internal components. Cleaning the filter typically resolves this issue.

• Question 497:

  A user acquired a new workstation and is attempting to open multiple targe Excel files simultaneously. The user is not experiencing the expected performance when executing such large requests.

  Which of the following should a technician do FIRST?

  A. Increase the swap partition.
  B. Upgrade the CPU in the workstation.
  C. Upgrade the power supply in the workstation.
  D. Upgrade the RAM in the workstation.
  D. Upgrade the RAM in the workstation.

  ---

  Explanation

  Opening multiple large Excel files simultaneously requires a large amount of RAM. Upgrading the RAM in the workstation should improve performance.

• Question 498:

  Which of the following connectors will uplink a new ISP cable modem to its wall jack?

  A. F-type
  B. LC
  C. RJ45
  D. Lightning
  A. F-type

  ---

  Explanation

  A cable modem connects to an ISP's wall jack using a coaxial cable, and the standard connector used for coaxial connections is the F-type connector. According to CompTIA Core 1 (220-1201) networking hardware and cabling objectives, F- type connectors are specifically designed for coaxial cabling used in cable television and cable internet (DOCSIS) installations. These connectors screw onto the coaxial wall outlet and the cable modem, ensuring a secure physical connection and proper signal transmission.

  An LC connector is a fiber-optic connector commonly used with single-mode or multimode fiber cables and is not associated with cable modems. An RJ45 connector is used for Ethernet networking and is typically used to connect the cable modem to a router or computer, not to the wall jack. Lightning is a proprietary Apple connector used for charging and data transfer on mobile devices and has no role in network uplinks.

  CompTIA expects candidates to clearly distinguish between different cable types and connectors based on the service being installed. When the scenario involves a cable modem and ISP wall jack, the correct and standard connector is the F- type.

• Question 499:

  Which of the following networking hardware devices is primarily used to connect different network segments and forward data based on MAC addresses?

  A. Router
  B. Switch
  C. Modem
  D. Firewall
  B. Switch

  ---

  Explanation

  A switch is the device that primarily forwards traffic based on MAC addresses and is used to connect devices within the same local network. It operates at Layer 2 (Data Link) of the OSI model. When a switch receives an Ethernet frame, it reads the source MAC address and records it in its MAC address table along with the port it arrived on. Then, when the switch needs to send a frame to a destination, it looks up the destination MAC address in that table and forwards the frame only out the correct port. This makes switching efficient and reduces unnecessary traffic compared to older hub-based networks. In CompTIA A+ Core 1, recognizing that MAC-based forwarding is a key switch function is essential.

  A router forwards traffic based on IP addresses at Layer 3 and is used to connect different IP networks or VLANs. A modem converts signals for ISP connectivity (e.g., cable/DSL/fiber handoff) and does not forward frames by MAC table learning. A firewall filters traffic based on security rules and is not primarily a MAC-forwarding device. Therefore, the best answer is Switch.

• Question 500:

  Several storms cause mission-critical servers to go offline unexpectedly. A server also goes offline suddenly due to haroNvare failure. Upon assessment, the company purchases new UPSs to condition power and allow the OSs to shut down gracefully in the event of a power failure. However, the UPSs are delayed due to supply chain issues.

  Which of the following can balance a cost-effective solution with uptime requirements?

  A. Purchasing backup generators
  B. Increasing input voltage
  C. Installing redundant PSUs
  D. Activating a hot site
  C. Installing redundant PSUs

  ---

  Explanation

  Option C: Installing redundant

  PSUs (Power Supply Units):

  Redundant PSUs provide fault tolerance by ensuring that if one power supply fails, another will take over seamlessly.

  This is a cost-effective way to increase uptime while waiting for the UPSs to arrive.

  Incorrect Options:

  Option A: Purchasing backup generators: Generators are costly and are typically used for long-term outages, not as an immediate or cost-effective solution.

  Option B: Increasing input voltage: This is not a practical solution to hardware failures or power issues.

  Option D: Activating a hot site: A hot site is an expensive, fully operational backup facility that would not be a cost-effective solution for this scenario.

  Key Takeaway: Installing redundant PSUs is a cost-effective way to balance uptime requirements in case of power or hardware failure.
