A field technician is configuring new mobile devices for a remote employee. The employee reports two separate issues: their corporate smartphone cannot authenticate on the cellular network after inserting a provisioned SIM card, and their laptop cannot transmit video signals when plugged into an external USB Type-C monitor. Which TWO of the following statements correctly identify the underlying causes of these issues? (Select TWO.)
- Cellular network device authentication requires registering the phone's unique IMEI physical hardware identifier, which is distinct from the SIM card's IMSI subscriber identifier.Answer
- Transmitting video over a USB Type-C connection requires the host device port to explicitly support DisplayPort Alternate Mode or Thunderbolt protocol.Answer
- CCellular carriers use the IMSI number embedded on the SIM card as the permanent physical device serial number to register phone hardware.
- DAll standard USB Type-C ports inherently provide native DisplayPort video signal output regardless of host chipset or protocol support.
Answer
The correct statements are that cellular network authentication requires registering the phone's unique IMEI hardware identifier (distinct from the SIM card's IMSI), and video output over USB Type-C requires explicit host support for DisplayPort Alternate Mode or Thunderbolt.
The solution is correct because cellular carriers track and provision physical device hardware using the IMEI while tracking subscriber accounts using the IMSI on the SIM card. Additionally, display output over USB Type-C requires hardware controller support for DisplayPort Alt Mode or Thunderbolt, as the physical port form factor alone does not ensure video capability.
