CompTIA 220-1101 Practice Test

Explanation: Streaks and multiple lines on print jobs are commonly caused by an issue with the toner cartridge, such as a damaged or improperly installed cartridge. The technician should replace the toner first as it is the most likely and simplest component to check.
✑ Why Not A (Rollers): Rollers primarily handle paper feeding and are less likely to cause streaking.
✑ Why Not B (Drum): While the drum can cause similar issues, the toner cartridge is easier to replace and should be checked first.
✑ Why Not D (Fuser): The fuser bonds toner to the paper, but it typically causes smudging rather than streaking.

Explanation: Upgrading a power supply to add a GPU typically requires more wattage to accommodate the additional power demands. Although the current power supply is 380W, adding a GPU with a six-pin power connector suggests a mid-range graphics card, which would likely need a total system power supply in the range of 450W to ensure adequate power for all components, providing a good balance between capacity and safety margins.

Explanation: When installing a printer on a network, the technician needs to configure the network settings, which include the IP address, subnet mask, and gateway. These settings are used to ensure that the printer can communicate with other devices on the network. When installing a printer on a network, the technician must configure the network settings of the printer to ensure that it can communicate with other devices on the network. This includes configuring the gateway, subnet mask and IP address of the printer.

The gateway is the device that connects the local network to other networks or the Internet. The subnet mask is used to determine which part of an IP address represents the network and which part represents individual hosts on that network. The IP address is a unique identifier for each device on a network.

Explanation: Security groups are used to manage access permissions to network resources, ensuring only authorized HR department members can access the shared materials.
✑ Why Not B (Audit logs): Audit logs monitor activity but do not restrict access.
✑ Why Not C (Time-of-day access): Time-of-day access limits when users can access resources but doesn’t specify user permissions.
✑ Why Not D (Print server): A print server manages print jobs but does not control file access. CompTIA A+ Exam Reference: Core 2 (220-1102), Section 2.5, access control and permissions.

Explanation: In this scenario, running a network cable over a long distance (279ft or 85m) and sharing conduit with a large power cable requires careful consideration of electromagnetic interference (EMI) and the physical distance limitations of the cable type. Fiber optic cables are immune to electromagnetic interference and can support much longer distances than copper-based cables like Cat 5e or Cat 6 without signal degradation. This makes fiber optic the most appropriate choice for this project.
