Question #62
A technician is installing a new high-end graphics card that uses a 12VHPWR connector.
Which of the following is the maximum wattage supported by this power connector?
- A . 400W
- B . MOW
- C . 600W
- D . 700W

An employee’s screen keeps flashing. Sometimes the picture goes out and comes back. The employee checks the power cord and confirms the device is plugged in fully.
Which of the following should a technician check for first?
- A . Loose video cable
- B . Failing graphics card
- C . Conflicting drivers
- D . Swollen motherboard capacitor
Correct Answer: A
A
Explanation:
Intermittent display issues, such as a screen flashing on and off, are most commonly caused by a loose or faulty video cable connection. If the power cable is confirmed secure, the next logical step is to check the video (data) cable between the monitor and the computer.

Question #65
An IT specialist compares Bluetooth and NFC technologies for mobile device connectivity.
Which of the following statements accurately describes a key difference between the two?
- A . NFC is faster than Bluetooth when transferring large files between devices.
- B . NFC consumes more power than Bluetooth, making it less suitable for devices in which battery conservation is crucial.
- C . NFC requires pairing with the receiving host, whereas Bluetooth just needs the available connection.
- D . NFC works best within a few centimeters, but Bluetooth can connect devices that are up to 32ft (10m) apart.
Correct Answer: D
D
Explanation:
NFC (Near-Field Communication) operates at very short ranges ― usually less than 4cm, and is ideal for quick, secure transactions like contactless payments. Bluetoothsupportslonger ranges (up to 10 meters or 32 feet) and is suited for ongoing connections like wireless headsets or file transfers.
Option A: Bluetooth is faster for large file transfers.
Option B: NFC uses less power, not more.
Option C: NFC doesnotrequire pairing ― Bluetooth does.

Question #66
Which of the following is an advantage of using VDI?
- A . Authentication is not required on a domain.
- B . Licensing costs are minimized.
- C . Less manual configuration is needed for each workstation.
- D . A virus is automatically contained locally.
Correct Answer: C
C
Explanation:
Virtual Desktop Infrastructure (VDI)hosts desktop environments on centralized servers. This allows rapid deployment and consistent configuration across multiple users, minimizing manual setup and easing IT management.
Option A: VDI still uses standard authentication methods.
Option B: Licensing can actually be more expensive due to virtualization software and backend servers.
Option D: VDI centralizes the desktop environment ― viruses would affect the virtual session, not be "contained locally."
