Question 14

Consider a Brocade Gen 5 fabric environment where administrative domains are configured. An administrator in Domain A creates a new Worldwide Name (WWN) alias for a specific host port and then creates a new zone that includes this alias. Simultaneously, an administrator in Domain B modifies an existing zone by removing the same host port from it. If the fabric\'s zoning commit process successfully propagates the changes from Domain A, resulting in the port being actively included in the newly created zone, what is the most likely state of the zoning configuration after both administrative actions are processed by the fabric\'s name server and distributed to all switches?

Accepted Answer

The new zone created in Domain A is active and includes the host port, and the existing zone modified in Domain B has the host port successfully removed.
