CompTIA A+ 220-701 Essentials Practice Test....(Part 1)

If the airflow is blocked, it means that the laptop is not able to properly dissipate heat. This can cause the internal components, including the processor, to overheat, leading to excessive heat being experienced by the customer.

In such a scenario it is important that you politely ask the co-worker to talk later after taking customer's permission to put him on hold. This is because the customers are very important for a company and putting them on hold for a long time or forwarding their call to another technician would annoy the customer.

The appropriate response for the customer in this situation will be to comfort user by telling him that you understand his concern, and will try to solve his problem as soon as possible so that he can finish and submit his research papers. Blaming him or giving him an unpractical suggestion will make the user think that you don't understand the urgency of his work and therefore not taking his problem seriously.

With twisted pair cable you can use RJ-45 connector. The UTP ( unshilded twisted pair) cable often is installed using a Registered Jack 45 (RJ-45) connector. The RJ-45 is an eight-wire connector used commonly to connect computers onto a local-area network (LAN), especially Ethernets

First check the boot order.

Electrical tape should be used to repair the wire with insulation damage. Electrical tape is specifically designed for electrical applications and provides insulation and protection against further damage. It is made of a non-conductive material and has adhesive properties that allow it to securely wrap around the damaged wire, providing a safe and reliable repair. Masking tape and duct tape are not suitable for electrical repairs as they do not provide the necessary insulation and may pose a safety risk. A wire nut is used to connect or splice wires together, but it is not designed for repairing damaged insulation.

The last step to take when installing a printer would be to print a test page. This step is usually performed after all the necessary software and drivers have been installed and the printer has been successfully connected to the computer. Printing a test page helps to ensure that the printer is functioning properly and that it is able to communicate with the computer. It also allows the user to check the print quality and make any necessary adjustments before using the printer for actual printing tasks.

Thermal printers require special paper to be used for printing because they use heat to create an image on the paper. The special paper used for thermal printing is coated with a heat-sensitive material that reacts to the heat generated by the printer, resulting in the desired image or text. This type of printer is commonly used for printing receipts, tickets, and labels.

A technician would go to the BIOS (Basic Input/Output System) to set up a password that would be required before booting into the operating system. The BIOS is a firmware that is responsible for initializing hardware during the booting process. It provides a user interface where various settings, including security measures like password protection, can be configured. By setting up a password in the BIOS, the technician can ensure that unauthorized users cannot access the operating system without entering the correct password during the booting process.

The advantage of upgrading your 32 bit Windows to a 64-bit version of Windows is that They supports more than 4GB of RAM and in some cases supports up to 128GB of RAM.

The best way to remove a USB device on a laptop computer is to stop the device first and then remove it from the laptop. This ensures that all data transfers are completed and the device is safely disconnected from the laptop, reducing the risk of data loss or damage to the device.

When planning to open and work on a CRT monitor, the technician should take high voltage discharge into consideration. CRT monitors contain a high voltage capacitor that stores electrical energy even when the monitor is turned off and unplugged. If the technician does not discharge this high voltage properly before working on the monitor, they could be at risk of electric shock. Therefore, it is important for the technician to take precautions and ensure their safety by discharging the high voltage before attempting any repairs or maintenance on the CRT monitor.

An inkjet printer shoots tiny droplets of ink onto the paper to create the desired print. This type of printer uses a printhead that contains several nozzles, which spray the ink onto the paper in precise patterns. The inkjet technology allows for high-resolution printing and the ability to produce vibrant colors. Unlike impact and dot matrix printers, which use physical contact to transfer ink onto the paper, the inkjet printer achieves printing without any physical contact, making it a popular choice for both home and office use.

A Virtual Private Network (VPN) shows all computers on the local network even if they are
physically located at a remote location.

To lengthen the life of computer hardware, it is best to clean out the dust with compressed air on a routine basis. Dust accumulation can cause overheating and damage to the internal components of the computer. Regularly cleaning out the dust helps to maintain proper airflow and prevent the hardware from overheating, thus extending its lifespan.

The SSID (Service Set Identifier) is broadcasted by default when setting up a WAP (Wireless Access Point) and should be disabled for security reasons. The SSID is the name of the wireless network and broadcasting it can make the network more vulnerable to unauthorized access. By disabling the SSID broadcast, the network becomes "hidden" and users need to manually enter the SSID to connect, adding an extra layer of protection.

The Ipconfig command is used to find the IP configuration information of a computer. The Syntax IPCONFIG /all displays full configuration information. You can type the Ipconfig command by clicking Start->Run and then typing cmd to open the command prompt to type the ipconfig command.

To set up a new operating system on your computer using the CD-ROM, you need to first create a partition and then format the partition to prepare it to be used by the OS and then install the operating system. The device driver installation is the part of the OS installation.

The correct answer is to check the vents for blockage first. When a workstation shuts down after extended periods of operation, it is often due to overheating. Checking the vents for blockage is important because if they are clogged with dust or debris, it can restrict airflow and cause the system to overheat. By clearing any blockages in the vents, the technician can ensure proper airflow and prevent the workstation from shutting down unexpectedly.

When setting up a lab with multiple wired PCs and a switch in a physical star network configuration, cable management to avoid trip hazards is important to consider. This means organizing and securing the cables properly to prevent them from becoming tangled or causing accidents. By keeping the cables neat and out of the way, the technician can ensure a safe and efficient working environment in the lab.

The technician would use the subnet mask 255.255.0.0 for a class B network because this subnet mask allows for a larger number of host addresses compared to the other options. A class B network uses the first two octets for the network portion, and the remaining two octets for the host portion. The subnet mask 255.255.0.0 means that the first two octets are used for the network portion, while the last two octets are used for the host portion, providing a larger range of possible host addresses.

The above scenario indicates that the hard drive being replaced is corrupt and damaged. Therefore, the drive must be removed and replaced again.

Laser printers use an electrostatic charge to create an image of the page onto a charged photoreceptor. This process involves a laser beam that scans across the photoreceptor, creating areas of positive and negative charge. The toner, which is negatively charged, is then attracted to the positively charged areas on the photoreceptor, forming the image. Finally, the toner is transferred onto the paper and fused using heat and pressure, resulting in the printed image.

PC card adapters should be removed before shipping a laptop to avoid damage during transit because they are external devices that can easily get detached or damaged during movement. Removing them ensures that they are not subjected to any stress or impact that could potentially cause damage. Additionally, removing PC card adapters also reduces the overall weight and size of the laptop, making it easier and safer to transport.

Fiber has the highest cost of implementation in a small office home office (SOHO) environment. This is because fiber optic cables are made of glass or plastic and require specialized installation and equipment. The cost of laying fiber optic cables can be expensive, especially for small offices or homes. Additionally, the equipment needed to connect to fiber networks, such as routers and modems, can also be costly. On the other hand, DSL, broadband, and satellite connections are generally more affordable and easier to install in a SOHO environment.

A technician would need a PCMCIA expansion slot in a laptop to install a cellular modem card. PCMCIA stands for Personal Computer Memory Card International Association and is a type of expansion slot commonly found in laptops. It allows for the installation of various types of cards, including cellular modem cards, which enable the laptop to connect to cellular networks for internet access. The other options, ISA, AGP 4X, and PCIe X16, are not commonly found in laptops and are not suitable for installing a cellular modem card.

DVD.DL offers the largest storage capacity among the given options. DVD.DL stands for DVD Dual Layer, which means it has two layers of data storage on one disc. This allows it to store more data compared to the other options like CD.RW, CD.R, and DVD.R. DVD.DL can typically store up to 8.5 gigabytes (GB) of data, making it the best choice for larger storage needs.

The interfaces that are usually available to you on the input side of the KVM switch include PS/2, VGA, and USB.

You need to use 802.11g standard if you want to use a standard that can support communication up to 54Mbps. 802.11x refers to the family of 802.11 standards, 802.11b supports communication only up to 11Mbps, and Bluetooth supports communication up to 3Mbps.

A DNS server is responsible for resolving host names to their corresponding IP addresses. When a user enters a website URL into their browser, the DNS server translates that URL into the IP address of the server where the website is hosted. This allows the user's device to establish a connection with the correct server and retrieve the requested web page.

The second partition is the recovery partition put by the manufacturer and how it is achieved is proprietary. Although the creation is based on slipstreaming technology the exact way each manufacturer achieves it is totally different and unique.

The most likely cause of the problem is that the account does not have permission to install drivers. This is because the technician has the correct, updated drivers but is unable to successfully install them. If the account does not have the necessary permissions, it would prevent the installation of the drivers.

The correct answer is Device Manager > Network adapters > Properties > Driver tab. This path allows users to access the Device Manager, where they can locate the network adapters section and access the properties of the specific NIC. From there, they can navigate to the Driver tab and upgrade the drivers for the network interface card.

The power brick or external power supply converts AC power to DC power that a computer can use to operate and charge its battery. This is necessary because most computers operate on DC power, and the power supply ensures that the correct voltage and current is provided to the computer. It also allows the computer to be used and charged without relying on a direct connection to an electrical outlet, enhancing its portability.

If a laptop computer has 25 or 9 pin connector with male pins on the back of it then it indicates that the laptop contains a Serial port. They are used for the RS-232 (serial) ports

Asking open-ended questions to gather the symptoms is the best approach for a technician to better understand the customer's issue. Open-ended questions allow the customer to provide detailed information about their problem, which can help the technician diagnose and troubleshoot more accurately. This approach also encourages effective communication and ensures that the technician has a comprehensive understanding of the issue before proceeding with any diagnostic tests or solutions.

Satellite usually has the highest latency compared to other options like fiber, DSL, and cable. This is because satellite signals have to travel a long distance from the Earth to the satellite in space and then back down again, resulting in a delay or latency in the transmission of data. Fiber, DSL, and cable connections are generally faster and have lower latency as they rely on physical cables that can transmit data at higher speeds without the need for signals to travel through space.

The information that should be documented when you change the refresh rate of your monitor is the old and the new refresh rate. Both the monitor and adapter have different refresh rates but they must agree on the refresh rate you select. If either device does not support a particular refresh rate, such a rate cannot be used therefore the refresh rate that was supported earlier and the new refresh rate is good information to be documented.

A false positive error in configuring biometric devices would be the most dangerous type of error. This means that the system incorrectly identifies an unauthorized person as authorized, granting them access to sensitive areas or information. This poses a significant security risk as it compromises the integrity of the entire biometric authentication system, allowing unauthorized individuals to bypass security measures and potentially cause harm or commit fraudulent activities.

The chassis of a PC is designed for proper internal airflow across the various components. However, if your PC's enclosures are open, then the cooling of the PC changes dramatically. The cooling of some components can be reduced or totally eliminated and can cause damage.

If a printer is not working for a particular user then the first thing that you should try is to print a testpage from the computer which is unable to use the printer. If that does not work then you mayneed to delete and reinstall the printer.
Printing a test page using the printer's self-test will not lead you anywhere because it can only tellthat the printer is printing fine, which you already know. You should always use the test page feature from the printer properties, not from an application, to test printing.

Improper disposal of a CRT (Cathode Ray Tube) can lead to the release of mercury, which is a hazardous substance. CRTs contain a small amount of mercury in the form of phosphor powder, which is used to create the display. If not disposed of properly, the mercury can leach into the environment, contaminating soil and water sources. Mercury is a toxic substance that can have harmful effects on human health and the ecosystem. Therefore, the correct answer is mercury.

Impact printers use a mechanical mechanism to strike or impact an inked ribbon onto the paper, leaving an impression of the desired text or image. This process is similar to using a typewriter, where physical force is applied to transfer the ink onto the paper. Unlike other printer types that use heat or spraying mechanisms, impact printers are known for their reliability and ability to create carbon copies.

A biometric fingerprint reader is a cost-effective technology that can be implemented on desktops and laptops to meet security considerations and reduce internal password reset costs. This technology allows users to authenticate themselves using their unique fingerprints, eliminating the need for passwords and reducing the risk of password-related security breaches. Additionally, fingerprint readers are relatively affordable and widely available, making them a practical choice for organizations looking to enhance security while minimizing costs.

The most likely cause for the print job failure indicated by the balloon in the system tray is that the paper needs to be replenished. This is because if the printer runs out of paper, it will not be able to print the document successfully.

The voltage selector switch is used to allow the power supply to operate at different voltages. This means that it can be adjusted to match the voltage requirements of different devices or regions. By selecting the appropriate voltage, the power supply can provide the necessary power to the connected devices without causing any damage.

The technician should recommend that the user access the print queue and pause all print jobs as the first step. This will temporarily stop all printing tasks and allow the printer to catch up and potentially resolve any issues causing it to print constantly. Restarting the spooler service or rebooting the computer may not address the underlying problem, and purchasing a new USB cable is unlikely to solve the issue if the printer is already receiving print jobs.

Configuring the display settings on the monitor would be the most likely solution to fix the problem. By adjusting the display settings, the user can change the resolution, screen size, and other display parameters to ensure that the desktop appears properly on the monitor. This can help in eliminating the black border and resizing the desktop to its usual size.

The technician should recommend booting using Last Known Good Configuration as the first step. This is because after running a registry cleaning program, there may have been changes made to the registry that are causing the computer to not boot properly. Booting using Last Known Good Configuration allows the computer to start using the most recent settings that were known to work correctly, which can help resolve the booting issue.

The correct command line to uninstall the Windows XP Service Pack 2 is SPUNINST.EXE. This command is specifically designed for uninstalling service packs in Windows XP.
