The correct answers are Create sensitivity labels through the Contoso Compliance Portal or the governance console, Publish sensitivity labels by adding them to a label policy, and Use PowerShell cmdlets to configure additional label settings.

Create sensitivity labels through the Contoso Compliance Portal or the governance console is correct because administrators use those interfaces to author labels and to define classification and protection options. The portal and governance console provide the GUI tools for creating label names descriptions and default settings and they are the usual starting point for deploying labels.

Publish sensitivity labels by adding them to a label policy is correct because labels must be published before they are available to users. A label policy controls which labels are visible to which users or groups and lets you configure policy settings and rollout timing so publishing is the deployment step that makes labels live.

Use PowerShell cmdlets to configure additional label settings is correct because PowerShell enables automation and the configuration of settings that may not be exposed in the portal. Cmdlets support bulk operations advanced configuration and scripting which help with large scale or repeatable deployments.

Delete sensitivity labels with no impact on existing protected data is incorrect because deleting a label can affect label availability and administrative control and the statement that there is no impact is not reliable. Existing labeled content may remain protected or may become harder to manage or recover depending on how protection was applied so the claim is unsafe.
