A technician needs to replace a failed laptop hard drive. What are the possible form factors of this hard drive? (Choose two)
- 3”
- 8”
- 5”
- 5”
- 8”
- 5”
Laptop hard drives will be one of two form factors (sizes): 1.8″ or 2.5″. Desktop computers have historically used 3.5″ hard drives
What type of wearable technology device is specifically designed to track a user’s movements and heart rate and may include features such as GPS?
Smart watch
Fitness monitor
Smart headset
Fitness monitor
A fitness monitor is normally worn on the wrist, and it tracks a user’s movements and heart rate. Some fitness monitors will be able to track sleep patterns and have a clock, alarm, and other features such as GPS. All fitness monitors have the ability to sync to a device such as a smartphone, laptop, or desktop
Your company is producing posters for an upcoming public relations campaign. The project leader wants to embed information into an NFC tag in the poster. How much information can this tag hold?
8 KB
- 4 KB
- 4 KB
8 KB
Near-field communication (NFC) is a wireless technology that uses radio frequency (RF) signals with limited range, about 4″ (10 cm). To read an NFC tag in a poster, you would move your phone close to the tag, and the phone would generate a small RF field that would power the target. Data could then be read from the tag, which currently holds up to 8 KB of data
Which laptop expansion port technology was developed by Apple and supports a wide variety of peripheral devices?
USB
eSATA
Thunderbolt
Thunderbolt
Thunderbolt was codeveloped by Apple and Intel as an offshoot of the DisplayPort technology. Apple added support for PCIe and launched it in 2011. In terms of versatility, it’s really second only to USB. You will find video devices, hard drives (both HDD and SSD), printers, laptop docking stations, audio devices, and PCIe expansion enclosures that use Thunderbolt. Thunderbolt 3 is now compatible with USB-C
You have a laptop with an ExpreeCard/34 slot. Which of the following statements is true regarding installing expansion cards?
You can only plug in an ExpressCard/34 card
You can plug in an ExpressCard/34 card
or an ExpressCard/22 card
You can plug in an ExpressCard/34 card
or an ExpressCard/54 card
You can only plug in an ExpressCard/34 card
An ExpressCard/34 slot is only 34 mm wide and will only accept a /34 card. There are no ExpressCard/22 cards or ExpressCard Universal cards (there is a universal slot), and the /54 card will be too wide to fit into the slot
Which laptop display component is capable of discharging energy and causing severe injuries to technicians?
Screen
Backlight
Inverter
Inverter
The job of the inverter is to store and convert energy; they have the potential to discharge that energy. They can be dangerous to technicians, so be careful when working with them
Your new laptop has 4 GB system RAM and an integrated video card. The default settings specifics 512 MB of video memory. How much RAM is available for the processor to use?
4 GB
3.5 GB
3 GB
3.5 GB
Many laptops use shared video memory, meaning that system RAM is divided up for use between the processor and the video card. On these types of systems, the amount of RAM available for video is configured in the BIOS. Anything reserved for the video card is unavailable to the processor. In this case, subtracting half a gigabyte from 4 GB leaves the CPU with 3.5 GB
Oculus, Samsung, and HTC are manufacturers of what type of wearable technology devices?
Smart glasses
Smart headsets
VR/AR headsets
VR/AR headsets
Oculus VR specializes in virtual reality and alternate reality headsets (VR/AR headsets). Samsung and HTC, while manufacturing smartphones, also produce VR/AR headsets

200
204
240
204
DDR3 SODIMMs have 204 pins. DDR and DDR2 SODIMMS have 200 pins each, and older SDDRAM has 144 pins
You need to replace a failed laptop hard drive. The user’s has asked that the new hard drive be as fast as possible, regardless of disk space or cost. What type of drive should you install?
SSD
Magnetic
Hybrid

Tablet computers feature touch screens that are approximately what size?
Between 3” and 5”
Between 7” and 12”
Between 12” and 24”
Between 7” and 12”
Tablet screen sizes typically fall anywhere between 7″ and 12″, although you can find much larger ones with 24″ displays
Which mobile technology device makes use of an augmented reality display?
Smart watch
Smart camera
Smart glasses
Smart glasses
