220-1101 Exam Dumps - CompTIA A+ Certification Exam: Core 1

A crimper and a clamp-style wire stripper are tools most likely needed to complete the relocation of a router access point. The crimper is used to attach RJ45 connectors to Ethernet cables, which is essential when creating custom-length cables for precise placement of the router access point. The clamp-style wire stripper is used to strip the insulation from the twisted-pair wiring without damaging the wires, preparing them for crimping. These tools are fundamental for network cable management and modifications, aligning with the network infrastructure setup and modifications detailed in the CompTIA A+ Core 1 (220-1101) Exam Objectives under sections related to networking and hardware troubleshooting .

The most likely answer is C. The pen batteries need recharging.

An active touch pen is a stylus that uses a battery to power features such as pressure sensitivity, buttons, or Bluetooth connectivity. If the pen batteries are low or depleted, the pen may stop working or become inaccurate1. To fix this issue, you should recharge the pen batteries using the provided charger or cable, or replace them with new ones if they are not rechargeable1.

The other options are less likely to cause the issue. A scratched tablet screen may affect the touch sensitivity, but it should not affect the pen functionality. The pen software may need updating to improve performance or compatibility, but it should not stop the pen from working altogether. Software updates may disable the pen if they change the settings or drivers, but this can be fixed by re-enabling the pen or reinstalling the drivers2.

An imaging drum is a component of a laser printer that transfers the toner to the paper. It is sensitive to light and can wear out over time, resulting in poor print quality or missing colors. If the cleaning cycle does not resolve the issue, the imaging drum may need to be replaced1.

A fuser is a component of a laser printer that heats and melts the toner onto the paper. It does not affect the color output of the printer, but it can cause paper jams, smudges, or wrinkles if it is defective2.

An ink cartridge is a component of an inkjet printer, not a laser printer. A laser printer uses toner, which is a dry powder, instead of ink, which is a liquid. An ink cartridge would not be compatible with a laser printer3.

A toner tank is a container that holds the toner for a laser printer. It can be either integrated with the imaging drum or separate from it. If the toner tank is empty or low, the printer will display a warning message and the print quality will deteriorate. However, if only one color is missing, the problem is more likely with the imaging drum than the toner tank4.

Resin is a material that is used in some types of 3D printers, not laser printers. Resin printers use a liquid resin that is cured by a light source to create solid objects. Resin has nothing to do with laser printing5.

The most likely answer is C. Fuser.

A fuser is a component in a laser printer that uses heat and pressure to fuse the toner powder onto the paper. If the fuser is damaged or worn out, it can cause humming and grinding noises, as well as ghost images on the printouts. Ghost images are faint copies of previous images that appear on the same page. They are caused by the fuser not heating the toner properly, or by the toner sticking to the fuser roller and transferring to the next page12.

To fix this problem, you should replace the fuser unit with a new one. You can check your printer manual for instructions on how to remove and install the fuser unit. You can also use a diagnostic ruler to measure the distance between the ghost images and determine if the fuser is the source of the problem2. If the ghost images are far apart (between 4cm and 5cm), then the fuser is likely to be faulty.

One of the possible causes of the error message “No Source Found” is that the projector is not receiving any signal from the connected device, such as a laptop1. This could be due to an incorrect input source selected on the projector or an improper display setting on the laptop. Therefore, the first actions that the technician should take are to verify the projector settings and make sure the correct input is selected, and to check the laptop display settings and set them to extend/duplicate23.

The first step in troubleshooting any network connectivity issue is to identify the scope and source of the problem. The technician should check if any infrastructure changes have been made during the user’s absence, such as updates, patches, configuration changes, or hardware replacements. These changes could affect the network settings, firewall rules, permissions, or compatibility of the user’s device or the server. The technician should also verify if other users or devices can access the server or if the problem is isolated to the user’s device. By determining if any infrastructure changes have been made, the technician can narrow down the possible causes and formulate a theory to test.

The best way to improve the efficiency of the process of formatting and reconfiguring a development PC after every application test is complete is to implement a sandbox. A sandbox is a virtual environment that isolates the application from the rest of the system, allowing the developer to test the application without affecting the main operating system, files, or settings. A sandbox can also be easily reset, deleted, or duplicated, saving the time and effort of formatting and reconfiguring the PC. A sandbox can also provide security benefits, such as preventing malware or bugs from spreading to the system or the network.

Other options, such as installing an SSD, disabling hyperthreading, or enabling hardware acceleration, may improve the performance of the PC, but they do not address the issue of formatting and reconfiguring the PC after each test. An SSD (solid state drive) is a storage device that uses flash memory instead of spinning disks, and it can offer faster data access, lower power consumption, and less noise and heat. Hyperthreading is a feature of some CPUs (central processing units) that allows each core to run two threads simultaneously, increasing the multitasking and parallel processing capabilities of the PC. Hardware acceleration is a technique that uses the GPU (graphics processing unit) or other specialized hardware to perform some tasks faster than the CPU, such as rendering graphics, video, or audio.

A crimper is a tool that is used to attach connectors to network cables, such as RJ-45 or RJ-11. A technician might need a crimper to create a longer cable for the router access point or to replace a damaged connector.

A Wi-Fi analyzer is a software or hardware tool that can scan and measure the wireless signal strength, interference, channel usage, and security of a Wi-Fi network. A technician might need a Wi-Fi analyzer to find the optimal location and configuration for the router access point to improve the signal coverage for the SOHO client.
