By `Default` (unless cool access retrieval policy is configured otherwise), data blocks on the cool tier that are read randomly again become "warm" and are moved back to the hot tier. Once marked as _warm_, the data blocks are again subjected to the temperature scan. However, large sequential reads (such as index and antivirus scans) on inactive data in the cool tier don't "warm" the data nor do they trigger inactive data to be moved back to the hot tier. Additionally, sequential reads for Azure NetApp Files, cross-region replication, or cross-zone replication do ***not*** "warm" the data.
