Examine the Cisco UCS Director Workflow Designer workflow in the following exhibit: How many users must reject before VLAN 101 is prevented from being added to the service profile?

• 350-601 : All Parts

In this scenario, two users must reject before virtual local area network (VLAN) 101 is prevented from being added to the service profile. The Cisco Unified Computing System (UCS) Director Workflow Designer workflow in this scenario creates VLAN 101 after it starts. Before the next task is executed, the workflow requires the approval of a user named Joe. If Joe approves, the workflow attempts to add VLAN 101 to the service profile. If Joe does not approve, Jane is given an opportunity to approve. If Jane approves, VLAN 101 can be added to the service profile.
Cisco UCS Director Workflow Designer is a graphical user interface (GUI) that enables users to create automated workflows in a drag-and-drop fashion. Each task in a workflow is equipped with an On Success button and an On Failure button. Each button provides a drop-down list of other tasks in the workflow. In this way, the user can select which tasks are executed next if a task succeeds and which tasks are executed next if a task fails. Green arrows in Workflow Designer represent the On Success path. Red arrows represent the On Failure path.
In this scenario, the On Failure path of the WaitforUserApproval_Joe task is tied to the WaitforUserApproval_Jane task, which means that Jane gets an opportunity to approve the addition of VLAN 101 to the service profile if Joe does not. The On Failure path of the WaitforUserApproval_Jane task is tied to the Completed (Failure) task. By contrast, the On Success path of the WaitforUserApproval_Joe task is tied to the AddVLANtoServiceProfile task, as is the On Success path of the WaitforUserApproval_Jane task.
At least one user will need to approve in this scenario for VLAN 101 to be added to the service profile. The On Failure path of the WaitforUserApproval_Joe task is tied to the WaitforUserApproval_Jane task. The On Failure path of the WaitforUserApproval_Jane task is tied to the Completed (Failure) task. Therefore, there is no chance of successfully adding VLAN 101 to the service profile without user approval.
No more than one user will need to approve in this scenario for VLAN 101 to be added to the service profile. The On Success path of the WaitforUserApproval_Joe task is tied to the AddVLANtoServiceProfile task. Therefore, the workflow attempts to add VLAN 101 to the service profile if Joe approves. Similarly, the On Success path of the WaitforUserApproval_Jane task is tied to the AddVLANtoServiceProfile task. Therefore, the workflow attempts to add VLAN 101 to the service profile if Joe rejects and Jane approves.
Only two user approval tasks are present in this workflow: WaitforUserApproval_Joe and WaitforUserApproval_Jane. Therefore, it is not possible to require more than two users to approve or reject the addition of VLAN 101 to the service profile.
