Free CompTIA ITF+ Infrastructure and Hardware Questions and Answers — Questions and Answers
Question 1: A technician is replacing a storage drive in a desktop computer. The user requires the fastest possible read and write speeds for large video files and the operating system. Which of the following storage types would be the BEST choice?
- Solid State Hybrid Drive (SSHD)
- Hard Disk Drive (HDD)
- Solid State Drive (SSD) (Correct answer)
- Optical Drive
Correct answer: Solid State Drive (SSD)
A Solid State Drive (SSD) uses flash memory to store data, which allows for significantly faster data access speeds compared to traditional Hard Disk Drives (HDDs) that use spinning magnetic platters. An SSHD is a combination of both but is not as fast as a pure SSD. An optical drive is used for reading/writing CDs, DVDs, or Blu-ray discs and is not suitable for primary storage.
Question 2: A user wants to connect multiple peripherals to their laptop, including an external monitor, a keyboard, a mouse, and a wired network connection, using a single cable. Which of the following devices is designed for this purpose?
- USB hub
- Docking station (Correct answer)
- KVM switch
- Network switch
Correct answer: Docking station
A docking station is a device that allows a laptop to connect to multiple peripherals like monitors, keyboards, mice, and networks with a single connection. A USB hub only expands the number of USB ports. A KVM switch allows control of multiple computers with one set of keyboard, video, and mouse. A network switch is only for connecting devices to a network.
Question 3: Which of the following internal computer components is responsible for connecting all other components and allowing them to communicate with each other?
- CPU
- RAM
- Motherboard (Correct answer)
- Power Supply
Correct answer: Motherboard
The motherboard, also known as the system board, is the main circuit board in a computer. It holds and allows communication between many of the crucial electronic components of a system, such as the CPU, RAM, and connectors for other peripherals.
Question 4: A user reports that their computer loses all its work whenever the power goes out, even for a moment. The data they were actively working on was stored in which type of memory?
- ROM
- SSD
- HDD
- RAM (Correct answer)
Correct answer: RAM
Random Access Memory (RAM) is volatile memory, meaning it requires power to maintain the data stored within it. When power is lost, the contents of RAM are erased. ROM, SSDs, and HDDs are all non-volatile storage, meaning they retain data even when the power is turned off.
Question 5: A small office/home office (SOHO) wants to set up a new wireless network. A technician purchases an all-in-one device that functions as a router, a switch, and a wireless access point. Which of the following security practices should be performed FIRST during the initial setup?
- Enable MAC address filtering
- Change the default administrator password (Correct answer)
- Disable the SSID broadcast
- Set up port forwarding for all devices
Correct answer: Change the default administrator password
The most critical first step in securing a new SOHO router is to change the default administrator username and password. Default credentials are often publicly known and can be easily exploited by attackers to gain unauthorized access to the network's configuration settings.
Question 6: Which of the following is an output device?
- Keyboard
- Scanner
- Monitor (Correct answer)
- Webcam
Correct answer: Monitor
An output device is any peripheral that receives data from a computer and presents it in another form. A monitor receives video signals from the computer and displays them as images. Keyboards, scanners, and webcams are all input devices, as they send data to the computer.
