Question asked in an interview

Hii my name is Aman,
I was asked this question in an interview,
That I have 3 access switch so how should I introduce these switches in a lan environment?
What are the steps ?

My answer was to configure one of the ports in all the 3 switch switches in trunk so they can pass the vlan information.

But they asked me what are the steps so I get confused because I told them the whole trunking configuration but I think still the interviewer didn’t satisfied from my answer.

Is there any other way to answer it.

We will check if they are old switch, we will delete the old configuration.
we will delete vlan.dat file present in flash memory.
Than connect switches in the lan network.
