• Question 344:

  Which of the following is used to install a network device when electrical outlets are unavailable?

  A. WWAN
  B. ONT
  C. NFC
  D. PoE
  D. PoE

  ---

  Explanation

  Power over Ethernet (PoE) is specifically designed to power network devices without requiring a separate electrical outlet. According to CompTIA Core 1 (220-1201) networking hardware objectives, PoE allows both data and electrical power to be delivered over a single Ethernet cable from a PoE-capable switch or injector to the connected device.

  PoE is commonly used for devices such as wireless access points, IP cameras, VoIP phones, and access control systems, especially in locations where installing electrical outlets is difficult, expensive, or impractical. This makes PoE an ideal solution for flexible and scalable network deployments. WWAN (Wireless Wide Area Network) provides cellular-based network connectivity but does not supply power to devices. An ONT (Optical Network Terminal) converts fiber signals to Ethernet and requires its own power source. NFC (Near Field Communication) is a short-range wireless technology used for authentication and data exchange, not for powering network devices. CompTIA highlights PoE as a key networking technology that simplifies installations by reducing cabling requirements and eliminating the need for local power outlets.

• Question 345:

  A user cannot see the office multifunction printer in their laptop's print options. They have printed to the device in the past successfully. The user's laptop is connected to the guest wireless network. Other users on both wireless and wired computers can see and print to the printer.

  Which of the following will fix the issue?

  A. Power cycle the printer to refresh connectivity.
  B. Reset the closest wireless AP.
  C. Download the printer driver from the manufacturer's website.
  D. Connect the laptop to the corporate Wi-Fi.
  D. Connect the laptop to the corporate Wi-Fi.

  ---

  Explanation

  If the user is on a guest network and cannot access internal resources like printers, connecting to the corporate Wi-Fi will place the device on the correct subnet to access the printer.

  From CompTIA A+ 220-1101 Official Study Guide, Objective 2.2 -Network segmentation:

  "Guest networks are isolated from internal resources for security. Connect to the main corporate Wi-Fi to access shared devices."

• Question 346:

  A user reports intermittent Wi-Fi issues in an open office. Other users are not affected.

  What is the most likely cause?

  A. Interference from other Wi-Fi signals
  B. All users are on the same frequency
  C. The laptop's wireless card is malfunctioning
  D. The antenna is near a device creating electromagnetic interference
  C. The laptop's wireless card is malfunctioning

  ---

  Explanation

  Since only one user experiences the issue in a shared environment where everyone else has stable connectivity, CompTIA A+ suggests that the problem is most likely with the client device, not the network. The wireless card may be failing, overheating, or experiencing intermittent hardware faults.

  If other Wi-Fi signals or EMI (electromagnetic interference) were the cause, multiple users would be affected. Frequency congestion (Option B) also impacts groups, not a single device.

  CompTIA stresses that isolating whether the issue affects one user or many helps determine whether the fault lies with the network or device. Because the problem is isolated, the most probable cause is a malfunctioning wireless NIC in the user's laptop.

• Question 347:

  A customer is able to print most documents with their USB ink jet printer, but the system is unresponsive when printing a certain report from a custom application. Nothing will print until the computer is restarted and the printer is power cycled.

  A technician remotes into the PC and confirms that the spooler stops working when this report is sent. After cleaning the spooler and reinstalling the drivers from the manufacturer's website, the issue persists. No other sites using the application report similar issues.

  Which of the following is most likely causing the issue?

  A. The manufacturer is curating content before it reaches the device to preserve ink.
  B. The application has a bug that the developer needs to address.
  C. The system is using the PostScript language instead of the PCL.
  D. Personal preferences have changed and documents with graphics are now online-only
  B. The application has a bug that the developer needs to address.

  ---

  Explanation

  If a print spooler crashes specifically with one application and no issue occurs on other systems, the most likely root cause is a bug within that specific application. Restarting the spooler and reinstalling drivers resolves system-wide or hardware-related issues--not app-specific failures. This indicates the application may be sending malformed print data.

• Question 348:

  A user cannot access the internet from a corporate laptop. All other employees can. The technician reviews the laptop's configuration:

  IP Address: 169.254.2.162

  Which explains the reason the user cannot access the internet?

  A. The subnet mask is misconfigured.
  B. The NIC is not using the latest driver.
  C. Network settings are only configured to IPv6.
  D. The DHCP server is unable to assign an address.
  D. The DHCP server is unable to assign an address.

  ---

  Explanation

  An IP address beginning with 169.254.x.x is an APIPA address (Automatic Private IP Addressing). CompTIA A + explains that APIPA is assigned automatically by Windows when the NIC cannot reach a DHCP server. This indicates the laptop requested an IP lease but never received one.

  APIPA addresses allow only local subnet communication and cannot access the internet , because no default gateway, DNS, or valid subnet configuration is provided. Since all other employees can access the internet, the DHCP server is functioning generally, but it is not delivering an address to this specific laptop--possibly due to cable issues, Wi-Fi authentication failure, DHCP scope exhaustion, or NIC misconfiguration.

  A subnet mask misconfiguration (A) would still show a normal IP, not APIPA. IPv6-only configuration (C) would not produce a 169.254 address. An outdated NIC driver (B) could cause network instability but does not directly generate APIPA.

  Thus, the root cause is that the DHCP server did not assign an IP address.

• Question 349:

  Which of the following connection methods allows a mobile device to share an LTE connection with other nearby devices?

  A. Bluetooth
  B. NFC
  C. Cellular
  D. Hotspot
  D. Hotspot

  ---

  Explanation

  Mobile devices can share their LTE or cellular data connection using a feature called tethering , more commonly known as hotspot mode. According to CompTIA A+ objectives on mobile networking technologies, a hotspot allows a smartphone or tablet to become a mini wireless router, broadcasting a Wi-Fi signal that nearby devices can connect to. The LTE (or 5G) connection is then shared over Wi-Fi, enabling laptops, tablets, or other phones to access the internet through the mobile device.

  Bluetooth is capable of tethering but provides much lower bandwidth and slower speeds--not ideal for sharing LTE widely. NFC is used for close-range data exchange or payment transactions and cannot share internet service. "Cellular" refers to the phone's own mobile network connection, not the mechanism for sharing it with others.

  Hotspot functionality is specifically built into modern mobile OSs and supports WPA2/3 encryption, password protection, and device whitelisting. This makes it the most common and efficient method to share LTE connectivity with multiple nearby devices.

  Thus, Hotspot (D) is the correct answer.

• Question 350:

  A student configures a wireless SOHO network to connect four laptops and one multifunction printer.

  Which setting ensures the printer is always available?

  A. Dynamic IPs for laptops, static IP for printer on same subnet
  B. Manually assign public IPs to laptops and printer
  C. Use APIPA for laptops and connect printer directly to ISP router
  D. Use dynamic IP addressing for all devices
  A. Dynamic IPs for laptops, static IP for printer on same subnet

  ---

  Explanation

  Printers in SOHO environments must maintain a consistent IP address so devices can regularly locate them for scanning and printing tasks. CompTIA A+ emphasizes assigning static IPs to network printers to prevent address changes that occur with DHCP.

  Laptops can remain DHCP clients because their address consistency is less critical. APIPA cannot communicate across networks and therefore should not be used. Assigning public IPs is incorrect and unsafe.

  By giving the printer a static IP within the same subnet, all laptops can reliably access it, and the network remains organized and functional exactly as the A+ objectives recommend.
