CompTIA 220-1201 Practice Test 12
Question 110
At Vertex Media, a technician working in laptop and mobile device repair identifies this issue: A user assumes every laptop USB-C port can send video to a USB-C monitor. The supporting record states that the port supports USB data and charging but not DisplayPort Alternate Mode. The desired outcome is to differentiate connector shape from electrical and protocol capabilities. The customer requires a verified fix rather than a guess based on one symptom. What should the technician verify first to establish the problem?
- Compare signed-in identity, calendar data source, sync permissions and last successful sync
- Check headset pairing mode, existing connections, Bluetooth visibility and adapter status
- Compare laptop USB-C video modes, dock Power Delivery wattage, and supported display count and resolution
- Check device and cable specifications for DisplayPort Alternate Mode, Thunderbolt or USB4 video support
Explanation
Correct Answer
D:
Check device and cable specifications for DisplayPort Alternate Mode, Thunderbolt or USB4 video support. It checks the likely failure boundary before altering working parts or settings. The relevant observation is that the port supports USB data and charging but not DisplayPort Alternate Mode. The support goal is to differentiate connector shape from electrical and protocol capabilities; this diagnose action specifically addresses usb-c connector versus supported protocol without confusing a different subsystem.
Incorrect Answers
A:
Compare signed-in identity, calendar data source, sync permissions and last successful sync. This action is appropriate for mobile calendar and contact synchronization, normally when a user's phone receives mail but calendar edits never appear on the company laptop. Here the observed facts require usb-c connector versus supported protocol instead.
B:
Check headset pairing mode, existing connections, Bluetooth visibility and adapter status. That action is appropriate for bluetooth headset pairing, normally when a wireless headset pairs with a tablet but does not appear on a new laptop's device discovery list. Here the observed facts require usb-c connector versus supported protocol instead.
C:
Compare laptop USB-C video modes, dock Power Delivery wattage, and supported display count and resolution. That action is appropriate for docking station display and power capability, normally when a small-business employee connects two monitors and power to a laptop through a new USB-C dock. Here the observed facts require usb-c connector versus supported protocol instead.
Question 111
During Crescent Operations's computer equipment refresh, the technician encounters this condition: A rarely used color inkjet skips cyan stripes despite a full cyan cartridge. The desired outcome is to use appropriate inkjet printhead maintenance instead of replacing laser consumables. Service work must follow power isolation, ESD, and manufacturer instructions when applicable. How should the solution first be tested on an approved spare or pilot system?
- Install a supported spare drive into a test board and check firmware discovery
- Print a nozzle-check test after one controlled cleaning cycle
- Print a controlled two-page sample from the target application
- Print a test page after inserting a compatible toner cartridge in a powered-down service state
Explanation
Correct Answer
