Direct topology change -----> no TCN generated packet. Indirect topology change ---------> TCN generated. is this correct? @rajan Sir?

Nops in both cases TCN will be generated, otherwise switches will never get to know that they have to delete CAM table entries.

Is there anything like Layer-2 MTU and layer-3 MTU? if yes, then what is the purpose of two different MTUs and how are they related?

Yes, There is L-2 MTU and L-3 MTU.

It depends on the size of Interfaces and technology which used.

Be clear in the place of L3 MTU it is basically IP MTU.

for general purpose, L2 MTU is Ethernet frame MTU which is larger in size since additional L-2 frame header is added.
