  There is VLAN Mismatch. Remember there is no any intervlan routing on the two sitches thus minimising the chance of communication. Answer is D https://www.youtube.com/watch?v=klqpX6U-_JY

  ChatGPT says, Based on the output for switch 1, the error that must be corrected in order for the ping test to be successful between PC A and PC B is option D, "There is a native VLAN mismatch." Explanation: The output of the show interfaces trunk command on Switch 1 shows that the trunk link between Switch 1 and Switch 2 is configured with a native VLAN of 10 on Switch 1 and a native VLAN of 20 on Switch 2. This is a native VLAN mismatch, which can cause issues with VLAN traffic crossing the trunk link. In this scenario, PC A is in VLAN 10 and PC B is in VLAN 20. When the switch receives traffic from PC A, it tags the traffic with VLAN 10, but when the traffic crosses the trunk link to Switch 2, the traffic is sent on the native VLAN 20, which Switch 2 is expecting to receive traffic on. As a result, the traffic from PC A is dropped and the ping test fails. To correct this error, the native VLAN on the trunk link between Switch 1 and Switch 2 should be the same on both switches. Either the native VLAN should be changed to 10 on both switches or it should be changed to 20 on both switches.

  Hi, wanted to input that this makes absolutely no sense at all.
