Difficulty: MediumMobile Device Synchronization and Cloud Integration

A mobile technician is setting up local data synchronization between a tablet and a desktop computer for an executive who frequently works in offline environments. The technician connects the tablet to a USB-C port on the desktop using the charging cable included with the tablet to transfer large media presentations. Although the desktop computer's USB-C port is rated for USB 3.2 Gen 2 speeds (10 Gbps), the file synchronization transfer rate remains capped at 480 Mbps. Which of the following is the most likely cause of this synchronization speed limitation?

  1. The connected USB-C charging cable only supports USB 2.0 data transfer specifications.Answer
  2. B
    The technician configured POP3 synchronization instead of Exchange ActiveSync on the desktop computer.
  3. C
    The mobile device's IMSI restricts local wired interface transfer bandwidth.
  4. D
    The desktop computer requires Mobile Application Management (MAM) policy approval to unthrottle physical data transfers.

Answer

The connected USB-C charging cable only supports USB 2.0 data transfer specifications.
While USB Type-C specifies the physical connector shape, it does not guarantee high-speed data transfer capabilities across all cables. Many bundled mobile charging cables include wires connected only for USB 2.0 data pins (480 Mbps max) alongside power delivery lines. To achieve USB 3.2 transfer speeds, both the host port, client device, and connecting cable must support the higher USB specification.

Step-by-Step Solution

1
Analyze the reported symptom and transfer speed bottleneck.
The file transfer speed between the tablet and PC is capped at 480 Mbps despite the host port supporting USB 3.2 Gen 2 (10 Gbps).
480 Mbps is the maximum theoretical transfer speed for the USB 2.0 standard.
2
Evaluate physical layer hardware components involved in the local synchronization.
The technician used a standard charging cable bundled with the tablet.
Manufacturers frequently bundle cables that support high wattage charging but only carry USB 2.0 data lines to reduce costs.
3
Identify the proper resolution for high-speed local device synchronization.
Replace the charging cable with a certified high-speed USB-C data synchronization cable.
A rated USB 3.2 Gen 2 cable will allow the connection to negotiate at the full speed supported by the host and client controllers.
