No - Not modified, created. No - Not accessed, created. Yes - Rules are matching the statement. The prefix "transactions" can be applicable for containers as well. "container" / "container/blob" or "blob" can be used under this context. Source: https://learn.microsoft.com/en-us/azure/storage/blobs/lifecycle-management-overview#archive-data-after-ingest No - "enableAutoTierToHotFromCool": "true" should be enabled.

I guess, third statement (The policy rule tiers..) result is Yes. Container name "transactions" is in prefixMatch. https://docs.microsoft.com/en-us/azure/storage/blobs/lifecycle-management-overview#archive-data-after-ingest Solution is: - No - No - Yes - No

Container name "transactions" is in prefixMatch means its name must start from "transactions". Its name is not "transactions". Dani_ac7's answer looks correct

Looks like 3rd is NO, according to filter's guide: "Filter blobs by name or first letters. To find items in a specific container, enter the name of the container followed by a forward slash, then the blob name or first letters. For example, to show all blobs starting with "a", type: "mycontainer/a"." So it looks like we are searching blobs with "transactions" prefix in all containers in 3rd.

But name "transactions" satisfies rule `name must start from "transactions"`, why it doesn't fit?

Correct: if you want to match the blobs within a specific container, you should mention the conatiner name/blob name { "rules": [ { "name": "agingRule", "enabled": true, "type": "Lifecycle", "definition": { "filters": { "blobTypes": [ "blockBlob" ], "prefixMatch": [ "sample-container/blob1", "container2/blob2" ] }, "actions": { "baseBlob": { "tierToCool": { "daysAfterModificationGreaterThan": 30 }, "tierToArchive": { "daysAfterModificationGreaterThan": 90 } } } } } ] }

wrong: An array of strings for prefixes to be matched. Each rule can define up to 10 case-sensitive prefixes. A prefix string must start with a container name. For example, if you want to match all blobs under https://myaccount.blob.core.windows.net/sample-container/blob1/... for a rule, the prefixMatch is sample-container/blob1

Block blobs prefixed with “transactions” will transition blobs that have not been modified in over 60 days to cool storage, and delete blobs not modified in 365 days. Yes. This is correct based on the rule provided. Blobs are moved to cool storage if they have not been accessed for 60 days. No. The rule is based on the creation date, not access date. The policy rule tiers previous versions within a container named “transactions” that are 60 days or older to the cool tier and deletes previous versions that are 365 days or older. No. The rule applies to block blobs with the prefix “transactions,” not specifically to previous versions within a container. Blobs will automatically be tiered from cool back to hot if accessed again after being tiered to cool. No. As you correctly pointed out, the rule does not specify “enableAutoTierToHotFromCool” as true. So, the correct answers should be: Yes, No, No, No.

3rd is YES, check the reference: https://learn.microsoft.com/en-us/azure/storage/blobs/lifecycle-management-overview On the page it says: "A prefix string must start with a container name. For example, if you want to match all blobs under https://myaccount.blob.core.windows.net/sample-container/blob1/... for a rule, the prefixMatch is sample-container/blob1." This means that the container name is "transactions" So the only one that make me confusing is the 4th. According to the discussion, you have to manually enable "enableAutoTierToHotFromCool". And it is also mentioned above in the link that "The enableAutoTierToHotFromCool action is available only when used with the daysAfterLastAccessTimeGreaterThan run condition. " As in our case, the prerequisite for the auto tier to hot from cool is not even fulfilled, so it is not possible to expect an "AutoTierToHotFromCool" effect. I would go with a NO for the 4th.

Box 3: No ? 'DayAfterCreationGraterThan 60' does not include 'just 60 days'. Therefore, if something has been made for 60 days, it would not be included in '60 days or later', so box 3 would be NO ?
