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

Verify that the OS supports hot swapping the RAM. Before replacing the RAM on an entry-level server with hot-swappable components, the technician should verify that the operating system supports hot swapping of RAM.

The IP address 192.168.1.56 is within the private IP address range (192.168.0.0 to 192.168.255.255) and is appropriate for use in an internal network utilizing NAT (Network Address Translation). The other IP addresses provided (172.15.65.10, 175.16.20.3, and 193.167.35.4) are either public IP addresses or not in the private IP range suitable for an internal network using NAT.

Tethering refers to sharing a mobile phone’s internet connection with another device, such as a laptop, either through USB, Bluetooth, or Wi-Fi. Tethering effectively turns the mobile phone into a personal hotspot for internet access.

Option A (IR): Incorrect. Infrared (IR) is used for short-range communication, such as remote controls, but it does not support internet sharing.

Option B (NFC): Incorrect. Near-field communication (NFC) is used for close-proximity data transfer, not for internet sharing.

Option C (Wi-Fi Direct): Incorrect. Wi-Fi Direct enables device-to-device communication but does not inherently provide internet sharing.

The digitizer converts touch inputs into digital signals, enabling touch functionality on a monitor. This component is essential for touch screens to process user input and is covered under the CompTIA A+ Core 1 objective on display technologies for mobile devices​.

In laser printing, the fuser unit is responsible for bonding the toner to the paper using heat and pressure. If the toner is not sticking to the paper, resulting in illegible documents despite trying different brands of paper, it indicates a problem with the fuser unit. It might not be reaching the necessary temperature to melt the toner properly, necessitating its replacement to ensure proper printouts.

To make sure that the new operating system on the USB drive loads automatically, the user must configure the boot options in the BIOS/UEFI. Boot options determine the sequence of devices the computer will attempt to boot from when powered on. Setting the USB drive as the first boot option ensures that the system will load from the USB before trying other devices.

D. Boot options: The user should configure the boot sequence to prioritize the USB drive, so the system boots from it automatically.

Why the other options are incorrect:

A. BIOS password: A BIOS password is used to restrict access to the BIOS settings, not to control boot order.

B. Trusted Platform Module (TPM): TPM is a security feature used for cryptographic operations and securing hardware, not for controlling boot options.

C. USB permissions: This refers to access permissions for USB devices but does not affect booting from a USB drive.

This concept is part of the Hardware domain in the CompTIA A+ Core 1 exam, specifically regarding BIOS configuration​.

USB devices rely on 5V output from the power supply, so the amperage rating at 5V is critical to ensure enough power is available for multiple USB devices. A modular connector count affects cable management, while a 20+4 power connector is standard for motherboard connections. Energy efficiency impacts overall power usage but is not specific to the needs of USB devices. This matches CompTIA A+ Core 1 objectives regarding power supply selection based on device requirements.

To allow multiple users to print to networked printers:

Printer shares enable users to access printers shared on the network.

Print servers manage print jobs and provide centralized control of printing.

Why Not B (DHCP server): DHCP is unrelated to print management.

Why Not D (Printer subnet): Subnets group devices but don’t manage printing.

Why Not E (SMB configuration): SMB is for file sharing, not specifically print management.

Why Not F (Printer Wi-Fi settings): These settings are irrelevant since the printers use Ethernet.
