What connector type is used by Thunderbolt 1 and 2?

  1. HDMI

  2. USB C

  3. MDP (Mini Display Port)

  4. VGA

The correct answer is: MDP (Mini Display Port)

Thunderbolt 1 and 2 use the MDP (Mini Display Port) connector type, not HDMI, USB C, or VGA. HDMI is a different type of connector commonly used for connecting devices to a TV or monitor. USB C, while it does support Thunderbolt 3, is not compatible with Thunderbolt 1 and 2. VGA is an older type of connector that is not commonly used anymore and is not compatible with Thunderbolt. MDP is the specific type of connector that was used for Thunderbolt 1 and 2 devices.
