Which of the following is best described as the atomic units of work in Cisco UCS Director Orchestrator?

  • rollbacks
  • approvals
  • service requests
  • workflows
  • tasks
Explanation:

Of the available choices, tasks are best described as the atomic units of work in Cisco Unified Computing System (UCS) Director Orchestrator. Cisco UCS Director uses hardware abstraction to convent hardware and software into programmable actions that can then be combined into an automated custom workflow. Cisco UCS Director Orchestrator is the Cisco UCS Director engine that enables this automation. A task is a single action and is therefore the smallest unit of work.
A workflow is a series of tasks and is therefore not the atomic unit of work in Cisco UCS Director Orchestrator. A workflow is a container that defines the order in which tasks should be performed. However, it is possible for a workflow to contain a single task. Workflows can be created and deployed from workflow templates.
Service requests are created when a workflow is executed and are therefore not the atomic unit of work in Cisco UCS Director Orchestrator. Service requests are Cisco UCS Director processes that can be exist in one of several states. For example, a service request that has not run yet might exist in a scheduled state. A service request that has been successfully executed exists in a completed state. A service request that was attempted but not successfully executed might exist in a failed state.
Approvals are points in a workflow that require user intervention. For example, a service request might exist in a blocked state if the request cannot complete until an administrator approves the service request. Approvals enable administrators to provide input values that can affect the product of a given workflow.
Rollbacks can be used to undo the results of workflows. For example, a workflow that creates unintended objects or components in a system can be rolled back so that those objects or components are removed. Cisco UCS Director Orchestrator rollbacks are different from relational database rollbacks in that they are not transactional. Instead, tasks in the workflow are executed in reserve order when a workflow is rolled back.
