   A technician is attempting to connect the wired LANs at two nearby buildings by installing a wireless point-to-point connection. Which of the following should the technician consider?

   • ANFC protocol data rate
   • BRFID frequency range
   • CBluetooth version compatibility
   • DAllowable limits for transmit power

   Show answer

   Answer: D

   Explanation

   When installing a wireless point-to-point connection between two buildings, the technician should consider the allowable limits for transmit power, which vary depending on the country or region. Exceeding these limits could interfere with other wireless devices or violate regulations. NFC protocol data rate, RFID frequency range, and Bluetooth version compatibility are not relevant for a wireless point-to-point connection.

3. Question 283 · 624 in bank

   An analyst has replaced the motherboard in a desktop computer that previously overheated. The analyst presses the power button, hears three beeps, and sees the screen is black. Which of the following is the best action for the analyst to take to fix this issue?

   • AReplace the power supply.
   • BReseat the RAM.
   • CReattach the hard drive.
   • DFlash the BIOS.

   Show answer

   Answer: B

   Explanation

   The best action for the analyst to take is B. Reseat the RAM. The symptoms described (three beeps and a black screen) are typically indicative of a RAM issue. The three beeps usually indicate a memory error, and the black screen suggests that the computer is not able to boot properly. Reseating the RAM (removing and reinserting it) may resolve the issue. Here's why the other options are not the best choice: A. Replacing the power supply may not address the specific issue, and it's unlikely that the power supply is causing the memory error. C. Reattaching the hard drive may not be relevant to the issue, as the computer is not booting far enough to access the hard drive. D. Flashing the BIOS may not resolve the issue, and it's a more complex process that should be attempted only if other troubleshooting steps have been exhausted. By reseating the RAM, the analyst can potentially resolve the memory error and get the computer booting properly again.

4. Question 284 · 624 in bank

   A technician is troubleshooting a network issue and needs to check the status of a local network device in the least disruptive manner possible. Which of the following tools should the technician use to accomplish this task?

   • ANetwork tap
   • BCable tester
   • CMultimeter
   • DTone generator

   Show answer

   Answer: A

   Explanation

   The correct answer is B. Cable tester. A cable tester is a tool that allows a technician to quickly and non-intrusively test the status of a network cable and the device it's connected to, without disrupting the network or other devices. It's a simple, handheld tool that can detect issues like cable faults, connectivity problems, or device status. Here's why the other options are not the best choice: A. A network tap is a passive device that copies network traffic for monitoring purposes, but it's not designed for troubleshooting local network devices. C. A multimeter is a tool used to measure electrical properties like voltage, current, and resistance, but it's not suitable for troubleshooting network devices. D. A tone generator is a tool used to trace cables and identify wiring issues, but it's not designed to check the status of a local network device. By using a cable tester, the technician can quickly and non-intrusively check the status of the local network device, minimizing disruption to the network and other devices.

5. Question 285 · 624 in bank

   A technician is working to replace a single DDR3 RAM module on a laptop that has two occupied slots. When the technician tries to turn on the laptop, the computer starts beeping and does not pass POST. The technician double-checks the newly installed RAM and notices a motherboard message indicating low voltage. Which of the following is the most likely cause of this issue?

   • AFaulty power adapter
   • BIncorrect BIOS settings
   • CFailing CMOS battery
   • DUnsupported memory

   Show answer

   Answer: D

   Explanation

   In this scenario, the technician is working to replace a single DDR3 RAM module on a laptop that has two occupied slots. DDR3 stands for Double Data Rate 3, and it is a type of memory technology that offers faster performance and lower power consumption than its predecessors. DDR3 RAM modules have different variants, such as DDR3L, DDR3U, or DDR3R, which have different voltage requirements. For example, DDR3L operates at 1.35V, DDR3U operates at 1.25V, and DDR3R operates at 1.5V.

6. Question 286 · 624 in bank

   A printer displays an error message even after a paper jam is cleared. Which of the following should a technician do to fix the issue?

   • ACheck the paper path for a blocked sensor.
   • BVerify the pickup roller is functioning.
   • CChange the duplex settings.
   • DRun internal printer diagnostics.

   Show answer

   Answer: A

   Explanation

   A. Check the paper path for a blocked sensor. Often, even after clearing a paper jam, a small piece of paper or debris might remain in the printer's paper path, obstructing a sensor and causing it to inaccurately detect a jam. By carefully inspecting the paper path and ensuring that all sensors are clear and unobstructed, the technician can resolve the issue and prevent the error message from persisting. Therefore, the correct answer is:

8. Question 288 · 624 in bank

   A technician is trying to fix a computer that fails to boot even when all the RAM is removed. Which of the following should the technician do next to troubleshoot the issue?

   • AInspect the motherboard for swollen capacitors.
   • BReplace the CMOS battery.
   • CSwap the power supply if it is inoperable.
   • DCheck to see if the HDD power connectors are well seated.

   Show answer

   Answer: A

   Explanation

   ChatGPT says: When a computer fails to boot without RAM, it typically means the system is not able to perform even the most basic functions necessary to initialize and begin the boot process. This often points to issues with critical components such as the motherboard, CPU, or power delivery mechanisms. n this scenario, the technician should focus on other components. The next step would likely be to check the motherboard for any signs of damage or malfunction, such as swollen capacitors, which could indicate a hardware failure. Therefore, the correct option would be: A. Inspect the motherboard for swollen capacitors.

9. Question 289 · 624 in bank

   A new VoIP solution is being implemented at a corporate office for more than 200 users. The new VoIP devices do not require AC adapters at the users' desks. Which of the following network devices should a technician purchase?

   • AFirewall
   • BPower injector
   • CPoE switch
   • DRouter

   Show answer

   Answer: C

   Explanation

   The correct answer is C. PoE switch. A PoE (Power over Ethernet) switch allows you to power devices like VoIP phones, wireless access points, and IP cameras over the same Ethernet cable that provides data connectivity. This eliminates the need for separate power adapters at each device, making deployment and maintenance easier. Here's why the other options are incorrect: A. Firewall: A firewall is a network security device that monitors and filters incoming and outgoing network traffic. It doesn't provide power to devices. B. Power injector: A power injector is a device that injects power into an Ethernet cable to power a PoE device. However, it's typically used for single devices, not for multiple devices. A PoE switch is a more efficient and scalable solution. D. Router: A router is a networking device that forwards data packets between networks. It doesn't provide power to devices. Therefore, a PoE switch is the most appropriate choice for powering VoIP phones in a corporate office. GG
