Zorluk: OrtaMobile Device Ports and Accessories

A field technician is deploying new mobile smartphones featuring USB Type-C ports to remote workers. The workers must be able to connect their smartphones directly to office monitors for presentations and rapidly transfer large video files to external storage drives. Which TWO of the following specifications must the technician verify on both the mobile device hardware controller and the connecting USB Type-C cables to fulfill these requirements? (Select TWO.)

  1. DisplayPort Alternate Mode (Alt Mode) support for external video transmissionCevap
  2. USB 3.2 protocol capabilities for high-speed data transfer throughputCevap
  3. C
    Universal Thunderbolt 4 protocol compatibility across all standard USB Type-C physical ports
  4. D
    Mobile Application Management (MAM) profile provisioning to enable physical port data throughput

Cevap

The technician must verify support for DisplayPort Alternate Mode (Alt Mode) for external video transmission and USB 3.2 protocol capabilities for high-speed data transfers.
To successfully present video on external displays via a USB Type-C port, the mobile device hardware and cable must support DisplayPort Alternate Mode (Alt Mode). To achieve high-speed data transfers with external storage drives, both the host device and cable must support USB 3.2 protocols, preventing data from falling back to USB 2.0 speeds.

Adım Adım Çözüm

1
Identify the video output requirement for external monitor display.
Confirm that USB Type-C ports do not output native video unless DisplayPort Alternate Mode (Alt Mode) is supported by the device's chipset and wired into the cable.
Alt Mode repurposes physical pins within the USB Type-C connector to transmit DisplayPort video signals directly.
2
Identify the high-speed file transfer requirement for external storage drives.
Confirm that both the mobile device controller and the cable explicitly support USB 3.2 standards.
Many basic USB Type-C cables only carry USB 2.0 data wiring internally, limiting transfers to 480 Mbps480\text{ Mbps} regardless of the physical connector.
