Difficulty: EasyMobile Device Ports and Accessories

A field technician is deploying new mobile devices and accessories for a team of remote inspectors. Which TWO of the following are distinct features of the USB Type-C port used on modern mobile devices?

  1. Reversible physical plug orientation that allows the connector to be inserted in either directionAnswer
  2. Support for Alternate Mode (Alt Mode) to transmit non-USB signals like DisplayPort videoAnswer
  3. C
    Requirement for an internal SO-DIMM expansion card to negotiate high-speed data transmission
  4. D
    Mandatory authentication using the device's cellular IMEI number before negotiating power delivery

Answer

The correct features are the reversible physical plug orientation that allows insertion in either direction, and support for Alternate Mode (Alt Mode) to transmit non-USB signals such as DisplayPort video.
The USB Type-C standard specifies a symmetrical, reversible physical connector that eliminates orientation issues when plugging in cables. Additionally, USB Type-C supports Alternate Mode (Alt Mode), allowing multiplexing of non-USB data protocols such as DisplayPort video directly across the cable pins.

Step-by-Step Solution

1
Identify physical features of USB Type-C connectors.
USB Type-C connectors feature a symmetrical 24-pin design that allows them to be plugged in without regard to orientation.
Reversibility is a core design standard for USB Type-C physical interfaces.
2
Identify signaling and protocol capabilities of USB Type-C ports.
USB Type-C hardware specifications include DisplayPort Alternate Mode (Alt Mode) capability for video transmission.
Alt Mode enables pins within the USB Type-C connector to carry native DisplayPort or HDMI signals directly to external displays.
