A+Graded |
PART I: CORE 1 (220-1101) EXAM
Q1. A user reports that their laptop screen is dim even when the brightness is set to
maximum. You suspect the inverter has failed. Which component does the inverter primarily
provide power to?
A. The LCD panel glass
B. The backlight (CCFL) [CORRECT]
C. The GPU
D. The digitizer
Correct Answer: B
Rationale: In laptops with older CCFL (Cold Cathode Fluorescent Lamp) backlights, the inverter
board converts DC power to high-voltage AC power to illuminate the backlight. A failing
inverter results in a dim screen where the image is still visible with a flashlight.
Q2. Which wireless technology is used by a laptop to communicate with a wireless headset at
a distance of approximately 1 meter for audio streaming?
A. NFC
B. IR
C. Bluetooth [CORRECT]
D. Z-Wave
Correct Answer: C
Rationale: Bluetooth is a Personal Area Network (PAN) technology designed for short-range
communication (up to 10m or 33ft typically) between devices like headsets, keyboards, and
mice.
,Q3. A technician is replacing a cracked screen on a smartphone. After reassembly, the display
works, but the touch functionality is unresponsive. Which component likely needs to be
reseated or replaced?
A. The LCD panel
B. The digitizer [CORRECT]
C. The inverter
D. The GPU
Correct Answer: B
Rationale: The digitizer is the layer responsible for interpreting touch input. On many
smartphones, the digitizer and LCD are fused, but if touch fails while the display is clear, the
digitizer connection or component is the issue.
Q4. A user wants to synchronize their iPhone with their corporate email, contacts, and
calendar stored on a Microsoft Exchange server. Which protocol facilitates this
synchronization?
A. IMAP
B. POP3
C. ActiveSync [CORRECT]
D. SMTP
Correct Answer: C
Rationale: Microsoft ActiveSync is the protocol designed to synchronize mobile devices with
Exchange servers, pushing email, calendar, and contact updates to the device in real-time.
Q5. A user needs to project their Android tablet screen to a larger display wirelessly for a
presentation. Which technology should they use?
,A. AirPlay
B. NFC
C. MHL
D. Miracast [CORRECT]

devices. AirPlay is Apple-specific. MHL requires a wired connection via HDMI.
Q6. A corporate IT department needs to remotely wipe a stolen employee device. Which
solution allows for this remote management capability?
A. GPS tracking
B. MDM (Mobile Device Management) [CORRECT]
C. Bluetooth tethering
D. IMEI blocking
Correct Answer: B
Rationale: MDM software provides a management console for IT administrators to enforce
policies, deploy applications, and perform remote actions like locking or wiping lost/stolen
devices.
Q7. Which biometric authentication feature is standard on modern smartphones for
unlocking the device without a passcode?
A. Facial recognition [CORRECT]
B. Smart card reader
C. Magnetic stripe reader
D. Barcode scanner
, Correct Answer: A
Rationale: Facial recognition (e.g., Face ID on iOS) and fingerprint scanners are the primary
biometric authentication methods used on modern mobile devices for security and ease of
access.
Q8. A user has a new 4K monitor and wants to connect their laptop to provide power, video,
and data transfer through a single cable. Which port type supports these features?
A. USB 2.0 Type-A
B. USB-C with Thunderbolt 3/4 or DisplayPort Alt Mode [CORRECT]
C. HDMI 1.4
D. DVI-D
Correct Answer: B
Rationale: USB-C is a versatile connector that can support power delivery (PD), video output
(via DP Alt Mode or Thunderbolt), and data transfer simultaneously.
Q9. A technician is setting up a new smartphone. The user requests that the device
automatically unlock when they are at home, using the phone's location services. Which
feature is the technician configuring?
A. Passcode lock
B. Context-aware authentication (Smart Lock) [CORRECT]
C. Biometric lock
D. Swipe lock
