NEW QUESTION 2

A technician assembled a new PC. After a few minutes, the computer slows down and then shuts itself off. Which of the following is the most likely cause of the failure?

• A. Thermal paste was not used.
• B. The GPU needs additional power.
• C. The memory is insufficient.
• D. The motherboard is incompatible.

Answer: A

Explanation:
The most likely cause of the failure is A. Thermal paste was not used.
Thermal paste, also known as thermal grease or thermal compound, is a substance that is applied between the CPU and the heat sink to improve the heat transfer and cooling of the CPU. Thermal paste fills the gaps and irregularities between the CPU and the heat sink, creating a better contact and reducing the thermal resistance .
According to some web search results , some signs and symptoms of not using thermal paste or using it incorrectly are:
•The CPU overheats and slows down or shuts down to prevent damage
•The CPU fan spins faster and louder to try to cool down the CPU
•The PC performance drops or becomes unstable
•The PC crashes or displays errors or blue screens
To fix this issue, the technician should apply thermal paste properly between the CPU and the heat sink, following these steps :
•Turn off the PC and unplug it from the power source
•Open the PC case and locate the CPU fan and heat sink
•Remove the CPU fan and heat sink from the motherboard
•Clean the surfaces of the CPU and heat sink with a lint-free cloth and alcohol
•Apply a small amount of thermal paste (about the size of a grain of rice) in the center of the CPU
•Reattach the heat sink and CPU fan to the motherboard, making sure they are aligned and secured
•Close the PC case and plug it back to the power source
The GPU needs additional power, the memory is insufficient, or the motherboard is
incompatible are not likely causes of the failure, since they would not cause the PC to overheat and shut down after a few minutes. The GPU needs additional power if it has a high power consumption that exceeds the capacity of the power supply or the PCIe slot. The memory is insufficient if it cannot handle the applications or tasks that are running on the PC. The motherboard is incompatible if it does not support the CPU, RAM, or other components that are installed on it. These issues may cause poor performance, errors, or crashes, but not overheating and shutting down.

NEW QUESTION 3

A technician is asked to set up a new laptop for a coworker. Which of the following storage devices and interfaces will provide the best performance? (Select two).

• A. 15,000rpm HDD
• B. M.2 SSD
• C. 10,000rpm HDD
• D. NVMe interface
• E. SATA interface
• F. mSATA interface

Answer: BD

Explanation:
M.2 SSD and NVMe interface are the best options for storage devices and interfaces that provide the best performance. M.2 SSD is a form factor that allows for faster data transfer and lower power consumption than traditional SATA SSDs. NVMe is a protocol that enables direct communication between the SSD and the PCIe bus, bypassing the SATA controller and reducing latency and overhead. Together, they offer the highest speed and efficiency for storage devices.

NEW QUESTION 4

A user reports intermittent connectivity. The technician checks the network logs and sees the following output:
Interface 0/1 Status Up Interface 0/1 Status Down
Interface 0/1 Status Up 13:03:20
Interface 0/1 Status Down 13:04:10 Switch elected as Root bridge
Interface 0/1 Status Up 13:05:40
Which of the following is the most likely reason for this issue?

• A. External interference
• B. High latency
• C. Jitter
• D. Port flapping

Answer: D

Explanation:
Port flapping, also known as link flapping, is a situation in which a physical interface on the switch continually goes up and down, causing intermittent connectivity for the devices connected to that port12. Port flapping can be caused by various factors, such as faulty or incompatible cables, hardware issues, configuration errors, or other network problems123. The network logs show that interface 0/1 on the switch changes its status from up to down and vice versa several times within a short period of time. This indicates that the port is flapping and affecting the network connectivity. The log also shows that the switch was elected as the root bridge, which means that it is the central point of a spanning tree protocol (STP) network. STP is a protocol that prevents loops in a network by blocking some ports and creating a tree-like topology. Port flapping can cause STP to recalculate the topology and change the status of the ports, which can further disrupt the network performance2.
To troubleshoot port flapping, the technician should check the physical and hardware aspects of the device, such as cables, SFPs, gigabit interface converters, and power supplies. The technician should also check the configuration settings of the port, such as auto-negotiation, duplex mode, speed, power-saving features, and smartport. The technician should also check for other network issues that may cause port flapping, such as link synchronization and spanning tree issues123.

• C. Turn the printer on and off to see if the error clears.
• D. Replace the fuser.

Answer: B

Explanation:
The MOST efficient next step the technician should complete is to check the printer paper path to locate any obstructions1. The error message “Paper Jam, Jam in fuser” indicates that there is a paper jam in the fuser2. The fuser is one of the parts of a laser printer most likely to fail without giving any explicit message2.
The printer LCD screen indicates a paper jam in the fuser. The most efficient next step the
technician should complete is to check the printer paper path to locate any obstructions. Applying a maintenance kit or replacing the fuser may not be necessary if the issue is caused by a paper jam.

NEW QUESTION 7

A user keeps a company-provided camera's battery charger plugged into a docking station at a desk. Company policy requires that USB devices be identified and approved by
installed peripheral security software. A technician is unable to add a unique identifier to the battery charger's security software. Which of the following should the technician do?

• A. Provide a USB to AC adapter for the battery charger.
• B. Add a powered USB hub to the docking station.
• C. Disable the peripheral security software for this user only.
• D. Replace the battery charger with a USB device that has a unique identifier.

Answer: A

Explanation:
The problem in this scenario is that the battery charger is not a USB device, but a device that plugs into a USB port to draw power. Therefore, it does not have a unique identifier that can be recognized by the peripheral security software, which is designed to prevent unauthorized USB devices from accessing the company’s network or data. The security software cannot add the battery charger to its whitelist, and may block its power supply or generate alerts.
The best solution for this problem is to provide a USB to AC adapter for the battery charger, which is a device that converts the USB power output to an AC power input that can be plugged into a wall outlet. This way, the battery charger does not need to connect to the docking station or the computer, and does not trigger the peripheral security software. The user can still charge the camera’s battery without compromising the company’s security policy.
The other options are not advisable because they either do not solve the problem or create new risks. Option B, adding a powered USB hub to the docking station, may not work if the security software also monitors the hub’s ports and detects the battery charger as an unknown device. Option C, disabling the peripheral security software for this user only, is a very bad idea because it exposes the user’s computer and the company’s network to potential attacks from malicious USB devices. Option D, replacing the battery charger with a USB device that has a unique identifier, is unnecessary and costly, and may not be compatible with the camera’s battery.

NEW QUESTION 12

A user has noticed high CPU temperatures when gaming. The user would like to lower the CPU temperature, and cost is not an issue. Which of the following should the user do to BEST cool the CPU while keeping noise to a minimum?

• A. Upgrade the thermal paste.
• B. Use a copper heat sink.
• C. Upgrade the CPU fan.
• D. Install liquid cooling.

Answer: D

Explanation:
Liquid cooling is a method of cooling the CPU by circulating a liquid through a closed loop that absorbs heat from the CPU and transfers it to a radiator. Liquid cooling is more effective and quieter than air cooling, which uses a fan and a heat sink. However, liquid cooling is also more expensive and complex to install. Upgrading the thermal paste, using a copper heat sink, or upgrading the CPU fan are ways to improve air cooling, but they will not lower the CPU temperature as much as liquid cooling.

NEW QUESTION 15

In a SOHO environment, a user wants to make sensitive, scanned documents available to other users on the domain. The logs need to indicate who accessed the documents and at what time they were accessed. Which of the following settings should a technician set up on the MFP device?

• A. Scan to email
• B. ADF tray
• C. PCL
• D. SMB share

Answer: D

Explanation:
The correct answer is D. SMB share.
SMB stands for Server Message Block, which is a network protocol that allows file and printer sharing among different devices on a local area network (LAN). An SMB share is a folder or drive that is shared using the SMB protocol and can be accessed by authorized users on the network. An MFP device is a multifunction printer that can perform multiple tasks, such as printing, scanning, copying, and faxing.
In a SOHO (small office/home office) environment, a user who wants to make sensitive, scanned documents available to other users on the domain can set up an SMB share on the MFP device. This way, the user can scan the documents to the SMB share and grant access permissions to the other users who need to view or edit them. The SMB share can also enable logging, which can record who accessed the documents and at what time they were accessed .
The other options are not the best settings for this scenario. Scan to email is a feature that allows the user to scan a document and send it as an email attachment to a recipient. This option may not be secure or convenient for sharing sensitive documents with multiple users on the domain. ADF tray stands for automatic document feeder tray, which is a component of an MFP device that can feed multiple pages of a document into the scanner or copier without manual intervention. This option is not related to sharing or logging scanned documents. PCL stands for Printer Command Language, which is a page description language that controls the layout and printing of documents. This option is not related to sharing or logging scanned documents either.

NEW QUESTION 16

Following a scheduled power outage, users report they cannot access the local intranet. A technician is able to ping the IP address of the server that is hosting the website. Which of the following serves is MOST likely offline?

• A. Web
• B. DNS
• C. File
• D. DHCP

Answer: B

Explanation:
DNS stands for Domain Name System and is a service that translates domain names (such as www.example.com) into IP addresses (such as 192.168.1.100) that computers can use to communicate over a network. If the DNS server is offline, users may not be able to access websites or other network resources by using their domain names, even if they are online and reachable by their IP addresses. The technician should check if the DNS server is running and configured correctly, or use an alternative DNS
server if possible. Reference: https://www.comptia.org/training/books/a-core-1-220-1101- study-guide (page 81)
