To ensure new releases of App1 are deployed only if they exceed defined performance baselines, with minimal administrative overhead, which feature should you configure?

An Azure Pipelines deployment gate is the correct choice because it allows you to automatically pause a deployment and evaluate external conditions, such as performance metrics from Azure Monitor, before proceeding. This ensures that the release only deploys if it meets predefined performance baselines, without requiring manual intervention. An Azure Pipelines release artifact defines the source of the deployment (e.g., a build output) but doesn't enforce performance criteria. An Azure Repos branch policy governs code quality and merging into branches, not deployment performance. An Azure Monitor alert notifies you of issues but doesn't automatically halt a deployment; it would require a separate automation to act on the alert.
