Question 460
During Riverlight Retail's workplace mobile support, the technician encounters this condition: A portable computer loses battery while attached to a cheap dock driving two 4K monitors. The desired outcome is to choose a dock meeting host charging and display requirements. The customer requires a verified fix rather than a guess based on one symptom. Which planned change most directly resolves the documented issue?
- Choose an active stylus certified for the device's digitizer protocol
- Select a compatible dock and power adapter with adequate charging wattage and video transport
- Grant the dispatch app only the location permission needed for its approved use
- Choose a supported video-capable port or active adapter instead of relying on connector shape
Explanation
Correct Answer
B:
Select a compatible dock and power adapter with adequate charging wattage and video transport. It corrects the documented cause using the compatible technology and support constraints. The relevant observation is that a portable computer loses battery while attached to a cheap dock driving two 4K monitors. The support goal is to choose a dock meeting host charging and display requirements; this design action specifically addresses docking station display and power capability without confusing a different subsystem.
Incorrect Answers
A:
Choose an active stylus certified for the device's digitizer protocol. This action is appropriate for active stylus digitizer compatibility, normally when a designer needs pen pressure and palm rejection on a convertible laptop.

This action is appropriate for location permission for navigation, normally when a dispatch app cannot show a user's current position on an otherwise connected smartphone. Here the observed facts require docking station display and power capability instead.
D:
Choose a supported video-capable port or active adapter instead of relying on connector shape. This action is appropriate for usb-c connector versus supported protocol, normally when a user assumes every laptop USB-C port can send video to a USB-C monitor. Here the observed facts require docking station display and power capability instead.
Question 461
A support request at Acorn Foods presents this problem: A replacement RAM order has the correct capacity but the wrong DDR generation. The supporting record states that the motherboard's socket and memory controller only support DDR4, not DDR5.
