A server connects to a port on an ArubaOS switch. The network administrator wants to ensure that the port remains forwarding during MSTP topology changes, and changes in the port status do not cause MSTP topology changes.
Which statement describes how the administrator can accomplish this?
A. The administrator can accept the default behavior of auto-edge.
B. The administrator can lower the port’s root path cost to zero.
C. The administrator can manually disable STP on the edge port.
D. The administrator can configure the port as an MSTP master port.

How do you configure that master port?
“ArubaOS switch ports are enabled for auto edge port detection by default. If the port does not receive a BPDU within three seconds, the switch defines the port as an auto edge port.”
answer is A.
I agree. A is the right answer. There`s no way to configure a port as “Master” one. As far as i know, STP can not be disable at port level as well.
Ans is A
Shane, a master port is in my understanding the lowest cost path from a mstp region to the cist. Assuming this is correct you would not be able to make a port connected to a server a Master port.
I think option A is the best choice here.
Anyone else who can enlighten us?
auto edge behavior will check for the BPDU’s on that port if it doesn’t receive any it will make the port as admin edge port, if it receives BPDU’s it will take participate in spanning tree. as per the question ” changes in the port status do not cause MSTP topology changes and it should be i always forwarding mode” that eliminates the option A,B and C .
D is the correct one . if you set the port as master port it will always be on forwarding state.
I bet A
C is also an option.
