In the Administering Windows Server Hybrid Core Infrastructure (AZ-800) study domain for Storage Spaces, Microsoft specifies that storage tiers are created within a single storage pool that contains two classes of media: a fast tier (typically SSD) and a standard/capacity tier (HDD). The guide states that storage tiers "use SSDs for frequently accessed ('hot') data and HDDs for less frequently accessed ('cold') data within the same storage pool," and that tiering is available only when the pool includes both SSD and HDD devices. It further clarifies that different HDD spindle speeds (e.g., 7,200 vs 10,000 RPM) do not constitute different media types for tiering-they are all HDDs.
Applying these rules to the table:
* Pool1 contains only HDDs (7,200-RPM and 10,000-RPM) and no SSDs, so it cannot host a tiered virtual disk.
* Pool2 contains HDDs (10,000-RPM) and SSDs, satisfying the requirement for both media types; it can create a tiered virtual disk.
* Pool3 contains HDDs (7,200-RPM) and SSDs, also satisfying the requirement; it can create a tiered virtual disk.
Therefore, only Pool2 and Pool3 support creating VDisk1 with storage tiers, making option A correct.
