Actual exam question from Cisco's 350-601

Question #: 247
Topic #: 1

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?
A.
✑ Configure SchedulerPolicy1 for leaf switches Blue1 and Red1, and SchedulerPolicy2 for leaf switches Blue2 and Red2.
Configure SchedulerPolicy1 and SchedulerPolicy2 with a one-time window trigger that has maximum concurrent nodes 1.

B.
✑ Configure SchedulerPolicy1 for leaf switches Blue1 and Red1, and SchedulerPolicy2 for leaf switches Blue2 and Red2.
✑ Configure SchedulerPolicy1 and SchedulerPolicy2 with a one-time window trigger that has maximum concurrent nodes 2.
C.
✑ Configure SchedulerPolicy1 for all four leaf switches Blue1, Blue2, Red1, and Red2.
✑ Configure SchedulerPolicy1 and SchedulerPolicy2 with a one-time window trigger that has maximum concurrent nodes 1.
D.
✑ Configure SchedulerPolicy1 for all four leaf switches Blue1, Blue2, Red1, and Red2.
✑ Configure SchedulerPolicy1 and SchedulerPolicy2 with a one-time window trigger that has maximum concurrent nodes 2.

Show Suggested Answer

Suggested Answer: A
We need to define maximum concurrent nodes of 1 to avoid impacting service.

Definitely A. B allows for all nodes to be upgraded at once.

ofc its not C, only SchPolicy1 contains the nodes. It must be A, we split each vpc leaves in two SchPolicies, and then we trigger them just once, and each time on each policy only one node is active, thus achieving the desired result

why not B, maximum concurrent node is 2, therefore all scheduler export should be successful The Maximum Concurrent Nodes value that is configured in a scheduler policy determines the number of configuration export policies to act at the time that is specified in the scheduler policy. For example, if the Maximum Concurrent Nodes is set to 1 in a scheduler policy and you have configured two export policies, both utilizing the same scheduler policy, one export policy is successful and other fails. However, if the Maximum Concurrent Nodes is set to 2, both configurations are successful. So, how you can make sure, which export policy will be success and which export policy will be failed ?

yh A makes sense but not 100% However, we recommend that you create separate update groups to upgrade switches on different schedules instead of relying on the concurrent capacity setting because the concurrent capacity setting doesn’t let you manage which switches in the same group are to be upgraded at the same time. If both leaf nodes in the same vPC pair are in the same switch upgrade group, only one of the leaf nodes is upgraded at a time regardless of the concurrent capacity.
