The patch panel is then connected to the switch using a patch cable.

NEW QUESTION 7

A technician is troubleshooting a computer that is not completing POST and gets stuck at the manufacturer logo screen. All internal, removable parts have been disconnected and only the minimum parts necessary to POST were reconnected. However, the symptoms remain the same. Which of the following should the technician try NEXT?

• A. Test the RAM in different slots, one at a time.
• B. Remove and test the power supply.
• C. Replace the motherboard.
• D. Change the CMOS battery.

Answer: A

Explanation:
Every computer has a CMOS battery and when you remove that battery, your computer will work almost the same as before. The only difference is you won’t be able to save any settings in the BIOS, which includes the date and time. If your PC is not booting after removing CMOS, you need to make sure that you have your CPU and RAM connected because it’s not possible for your system to boot without those.. Your motherboard and computer will be able to boot just fine even without a CMOS battery present. The only issue is all your BIOS settings will be reset and the time and date will be inaccurate. You will also be unable to save BIOS settings.

NEW QUESTION 8

A technician is troubleshooting an old desktop system that randomly shows a Windows BSOD or powers off unexpectedly. All system temperatures are within normal limits. Which of the following should the technician do NEXT?

• A. Visually inspect the motherboard capacitors.
• B. Verify all case fans are operational.
• C. Check that the BIOS version supports the installed CPU.
• D. Compare the software requirements with the installed RAM.

Answer: A

Explanation:
BSoDs can be caused by poorly written device drivers or malfunctioning hardware, such as faulty memory, power supply issues, overheating of components, or hardware running beyond its specification limits. In the Windows 9x era, incompatible DLLs or bugs in the operating system kernel could also cause BSoDs.

NEW QUESTION 10

A user reports that when pressing a radio button on a tablet, an item a couple of inches to the right of the pressed button gets selected instead. Which of the following components may need to be replaced?

• A. Gyroscope
• B. Battery
• C. Digitizer
• D. Glass

Answer: C

Explanation:
A digitizer is a component that converts the touch input on a tablet screen into digital signals that can be processed by the device. A digitizer consists of a thin layer of transparent material that covers the glass screen and has sensors that detect the position and pressure of the touch. If the digitizer is damaged, misaligned, or poorly calibrated, it can cause inaccurate touch input, such as selecting the wrong item or not responding at all12. Therefore, the most likely cause of the issue in this scenario is a faulty digitizer that may need to be replaced. The other components are not directly related to the touch input functionality of the tablet. A gyroscope is a sensor that measures the orientation and rotation of the device3. A battery is a power source that supplies electricity to the device4. A glass is a protective layer that covers the screen and prevents scratches and cracks5. References

NEW QUESTION 12

A user reports a monitor, keyboard, mouse. and headset are no longer functioning. The user has restarted the laptop and tested an alternative headset and monitor, but the issue persists. The technician notices the user has a printer. USB-C hub, and AC adapter plugged into the laptop. Which of the following should the technician do to MOST likely resolve the issue?

• A. Verify the AC adaptor voltage.
• B. Repair the operating system.
• C. Replace the user’s USB-C hub.
• D. Reinstall the drivers for affected devices.
• E. Make sure the printer is not drawing too much power.

Answer: C

Explanation:
The most likely cause of the issue is that the user’s USB-C hub is faulty or incompatible with the laptop. The USB-C hub is a device that allows the user to connect multiple peripherals to the laptop using a single USB-C port. If the hub is not working properly, it may prevent the monitor, keyboard, mouse, and headset from functioning. The technician should replace the user’s USB-C hub with a new one that is compatible with the laptop and test the peripherals again. Verifying the AC adapter voltage will not help with the issue, as the AC adapter is used to power the laptop, not the peripherals. Repairing the operating system will not help either, as the issue is not related to software. Reinstalling the drivers for affected devices may not help, as the issue may be caused by the hub, not the devices. Making sure the printer is not drawing too much power is irrelevant, as the printer is not connected to the hub or affecting the other peripherals.

NEW QUESTION 13

Which of the following utilizes TCP ports 20/21 and transfers data in cleartext?

• A. SNMP
• B. SSH
• C. FTP
• D. Telnet

Answer: C

Explanation:
FTP (File Transfer Protocol) uses TCP ports 20/21 and transfers data in cleartext, which means the data is not encrypted and can be read by anyone who intercepts it. This makes FTP insecure for transferring sensitive information. SSH (Secure Shell), on the other hand, uses port 22 and encrypts data, making it more secure. SNMP (Simple Network Management Protocol) uses ports 161/162 and is used to monitor network devices. Telnet uses port 23 and transfers data in cleartext, making it insecure.

NEW QUESTION 15

While implementing a non-carrier-grade wireless backhaul, a technician notices the current channel selection is externally polluted with various RF signals. Upon performing a spectral analysis, the technician discovers a channel containing almost no RF pollution. Unfortunately, the technician is unable to select that channel. Which of the following is the MOST likely reason for this issue?

• A. The channel is reserved for licensed band use.
• B. The channel selection is defective, contact the manufacturer.
• C. The channel must be unblocked by the vendor.
• D. The device requires a firmware update to unlock the channel.

Answer: A

Explanation:
The 2. band is subdivided into up to 14 channels, spaced at 5 MHz intervals from 2412 MHz up to 2484 MHz. Wi-Fi requires bandwidth of approximately 20 MHz, not 5 MHz. Consequently, a site designer needs to choose the channels that do not overlap. On a WLAN where only the first 11 channels are available, channels 1, 6, and 11 can be selected as non-overlapping. Note: In the Americas, regulations permit the use of channels 1-11 only, while in Europe, channels 1-13 are permitted. In Japan, all 14 channels are permitted.

NEW QUESTION 16

Which of the following describes the BEST use case for a client-side hypervisor?

• A. By For a software developer who is required to test an application in many environments
• B. When the data center environment is out of resources for a new server
• C. As a cost-saving measure to allow multiple users on one computer
• D. To provide a backup to cloud-based solutions during internet failures

Answer: A

Explanation:
A client-side hypervisor is a virtual machine monitor (VMM) that resides in and virtualizes a user’s computer, allowing it to run multiple operating systems (or virtual machines) on shared hardware12. A client-side hypervisor can be useful for a software developer who needs to test an application in many environments, such as different versions of Windows, Linux, or Mac OS. By using a client-side hypervisor, the developer can switch between different virtual machines without rebooting the computer or using multiple physical devices3.
