CompTIA A Plus 220 1001 Test 3 (Hardware)

The CompTIA 220-1001 exam is one of two exams requires to obtain the CompTIA A+ (1000 series). This exam will focus on hardware like hard drives, motherboards, CPUs, memory and peripheral devices.

  • Questions: 20
  • Time: 60 seconds per question (0 hours, 20 minutes, 0 seconds)

Rank the following starting with the fastest and ending with the slowest: IDE, SATA, SCSI


How many pins are present in SATA data and power cables?

  • 15 for both power and data
  • 15 for power and 7 for data
  • 8 for data and 12 for power
  • 40 for data and 4 for power

You are helping a friend build a new gaming PC. To save on costs they have opted to buy a new motherboard but keep their existing DDR2 memory from their previous PC. After having some trouble getting the memory to fit into the motherboard you check the motherboard manufacturer's documentation and find they recommend their own DDR3 memory. How should you proceed?

  • Buy the recommended memory from the same manufacturer as the motherboard
  • Purchase a DDR2 to DDR3 slot adapter
  • Purchase DDR3 memory from any manufacturer
  • Enable the DDR downgrade feature using a jumper on the motherboard's pins

Which statement most accurately describes RAID 10?

  • RAID 10 provides multiple striped disk backups
  • RAID 10 provides faster performance
  • RAID 10 provides data redundancy and faster performance
  • RAID 10 provides data redundancy

What of the following is a true statement regarding NVMe?

  • NVMe is a protocol for accessing data
  • NVMe is significantly faster than M.2 based drives
  • NVMe must use the PCIe form factor
  • NVMe is a type of hard drive connector

What of the following is a true statement regarding M.2 drives?

  • M.2 drives can read CD, DVD and Blu-ray disks
  • M.2 drives have a higher Rotations Per Minute (RPM) than SATA based drives
  • M.2 drives connect directly to the motherboard
  • M.2 drives use a 3 pin SATA cable
