exception vector and boot point address

I have one basic question related to the first address from where the processor starts executing.

What I understand is that the reset to the CPU is one type of exception. So, based on this, the processor starts executing from the address pointed by the exception table.

So, in the whole process of boot-up, where does this exception processing fall?

1) it is after boot-up

2) before boot-up

3) this itself is the boot-up
