問題文

A provider wants all consumers currently on v1 patch 3 to move to v2 patch 0. What action starts that migration?

選択肢

1. Setting the release directive on the channel to v2 patch 0, which queues every installed instance of the previous version for upgrade.
2. Asking each consumer to run the upgrade command, because automatic upgrades apply to patches only and versions always require consumer action.
3. Deregistering v1 from the application package, because removing the old version forces the installed apps onto the remaining one.
4. Adding v2 to the channel, because a channel always serves the newest version it holds and the directive only names a fallback.
