Difficulty: MediumMobile Device Ports and Accessories

A deployment technician is preparing company-issued mobile tablets equipped with USB Type-C ports for field employees. Which of the following statements correctly describe the physical characteristics and functional capabilities of USB Type-C mobile ports and accessories? (Select TWO.)

  1. USB Type-C uses a reversible 24-pin connector design that allows insertion in either orientation.Answer
  2. USB Type-C ports can utilize DisplayPort Alternate Mode (Alt Mode) to output native video signals directly to external displays.Answer
  3. C
    All physical USB Type-C ports automatically provide full Thunderbolt 3/4 data transfer speeds of up to 40 Gbps regardless of the host system controller.
  4. D
    Modern mobile Lithium-ion batteries charged via USB Type-C must undergo periodic deep discharge cycles down to 0% to retain capacity.

Answer

USB Type-C features a reversible 24-pin physical connector and can support DisplayPort Alternate Mode (Alt Mode) for native video transmission.
The statements confirming that USB Type-C is a 24-pin reversible connector and that it supports DisplayPort Alternate Mode for video output are accurate according to CompTIA standards.

Step-by-Step Solution

1
Identify physical features of USB Type-C
Confirm that USB Type-C uses a symmetrical 24-pin connector allowing reversible pin configuration.
This physical design prevents damage to ports and simplifies connection for end users.
2
Analyze protocol capability options for USB Type-C
Recognize that Alternate Modes allow native DisplayPort video to travel across USB Type-C lanes.
DisplayPort Alt Mode reassigns physical high-speed data lanes inside the cable to convey display traffic.
3
Evaluate distractor statements regarding protocol standards and battery maintenance
Reject the claim that all USB-C ports support Thunderbolt speeds, as USB-C is merely the physical connector form factor. Reject deep discharge battery procedures as outdated and detrimental to Li-ion chemistry.
Thunderbolt capabilities require dedicated controller support on the host system board.
