Can the os6400 stack port serve as an uplink port?

[20deoctubre]

Could it be said that if you have a stack port, that same port will serve as uplink port?
I'm studying for the ACFE exam and I have a practice question which says:
"The maximum number of 10Gig uplinks for the OS6400 stack is"
a) 0, b) 8, c) 16, d) 32

I know that this switch has 2 10G stacking ports (16 for a stack), but I'm not sure if these ports can serve as uplink too, so that is my doubt, Can a stacking port be utilized as an uplink port?

Regards...

It's not possible to use the stack ports as uplinks. Also there isn't at the 6400 a hardware version with 10Gig-uplinks. So 0 is correct. At 6850E-X there are two 10gig uplinks...

i think you misunderstand the question.
The question says: If you have a stack (of 8 switch max) , how many ports 10G can be used for uplink.
Am I rght?

No, I have the question understand correctly (also 5 years ago). at the 6400 there is NO 10G-ports (beside the stacking ports). So zero is correct.
But you will not find this question anymore in the ACFE because the switch is to old.....
