Why each option
Flash Pool aggregates, which combine SSDs as a cache tier with spinning disk capacity, were introduced at a specific Data ONTAP version and mode, and knowing this boundary is required for the exam.
Data ONTAP 8.1.1 Cluster-Mode was the first release to introduce Flash Pool support in Cluster-Mode, adding SSD caching to aggregates; this specific dot release extended the feature from 7-Mode into the clustered architecture for the first time.
Data ONTAP 7.3 predates the Flash Pool feature entirely; Flash Pool did not exist until the 8.1 release family.
Data ONTAP 8.1 7-Mode contained early Flash Pool groundwork but the full Flash Pool feature as a named, supported capability was delivered in the 8.1.1 revision, not 8.1.
Data ONTAP 8.1 Cluster-Mode did not yet include Flash Pool support; the Cluster-Mode implementation required the incremental 8.1.1 update to be introduced.
