Refer to the exhibit. An engineer must schedule the firmware upgrade of the Red1 and Red2 leaf switches. The requirement is to keep the upgrade time to the minimum, avoid any service impact, and perform the parallel upgrade Which set of scheduler attributes must be used to meet these requirements?

Correct Answer: B
To schedule the firmware upgrade of the Red1 and Red2 leaf switches with the requirements of minimal upgrade time, no service impact, and parallel upgrade, SchedulerPolicy1 and SchedulerPolicy2 with a one-time window trigger that has maximum concurrent nodes 2 should be used. This allows both Red1 and Red2 to upgrade simultaneously within the same maintenance window, thus minimizing the time and avoiding any service disruption.
