Core switch is connected to 2 distribution switches which are connected to 2 access switches. PC1 is connected to DSW1 and DSW2 root bridge. Link connected from PC1 to DSW2 is 4Gbps and DSW1 is 10gbps. There is an EtherChannel trunk between DSW1 and DSW2. Default port priority is configured. Change in port priority so traffic goes through DSW1 to DSW2. (Choose two.)
A. DSW1: spanning-tree port priority 16
B. DSW1: interface g1/0
C. DSW2: spanning-tree port priority 16
D. DSW2: interface g1/0
E. DSW1: spanning-tree port priority 0
This question is stupid, PC1 doesn’t participate in spanning-tree… it’s a computer, so why would you change the spanning-tree priority on those links? This is non-sense…
What Tom says is correct but you mentioned that there is no priority for 0 and there is
the values are and I quote : ” 0, 32, 64, 96, 128, 160, 192, and 224. All other values are rejected.”
that’s from the site you linked/
so the correct answer must be B and E 🙂
A. looking not correct
spanning-tree port-priority Syntax Description
Port priority. The range is from 1 to 224, in increments of 32.

so there’s no priority 16, 0, 32, 64, 96, 128
i’m for B and E
