`az resource link` is used to manage links between Azure resources, such as creating or deleting a relationship object. It does not retrieve the details of an Azure AI services account itself. Even if a Cognitive Services account exists, this command would not be the normal way to identify or inspect it. Therefore, it does not meet the requirement to identify the created Azure AI services account in a pipeline.

`az cognitiveservices account network-rule` is used to configure or manage network access rules for a Cognitive Services account. That means it is an administrative command for security settings, not a discovery or inspection command. To use it effectively, you would already need to know which account you are targeting. As a result, it does not minimize effort for identifying the newly created account.

az cognitiveservices account show retrieves the details of a specific Azure AI services (Cognitive Services) account. It returns key identifying information such as the ARM resource ID, location, SKU, and endpoint. In an Azure DevOps pipeline, this is the minimal-effort, most direct way to identify the created account for subsequent steps.

`az account list` lists the Azure subscriptions or account contexts available to the signed-in CLI identity. It helps determine which subscription or tenant is active, but it does not return Azure AI services resources. The command operates at the authentication and subscription scope rather than the Cognitive Services resource scope. Therefore, it cannot directly identify the created Azure AI services account.
