Exam AZ-104 topic 3 question 42 discussion

I don't think this is correct Rule1 archives blobs(aka files) after 2 days of inactivity and deletes after 9 Rule2 moves to cool tier after 3 days and archive tier after 9 Of the three files, Rule1 only applies to Dep1File1.docx, while the other files have Rule2 applied. The question asks if you can read the files on the 10th, not if they still exist. Files in the archive tier CANNOT be read as documented by Microsoft: "While a blob is in archive storage, the blob data is offline and can't be read or modified. To read or download a blob in archive, you must first rehydrate it to an online tier." https://docs.microsoft.com/en-us/azure/storage/blobs/storage-blob-storage-tiers Dep1File1.docx was last updated 8 days ago, and would be in archive tier File2.docx was last updated 5 days ago, and would be in cool tier File3.docx was last updated 8 days ago and would be in cool tier Dep1File1 > No cannot be read File2 > Yes cannot be read File3 > Yes can be read

Correct Answer N Y Y Dep1File1 is hit by rule 1 which will archive the file by the 10th rendering it unreadable File 2 and file3 are missed by the first rule and gets hit by the 2nd rule, which will make them still readable by the 10th https://docs.microsoft.com/en-us/azure/storage/blobs/archive-rehydrate-overview#:~:text=While%20a%20blob%20is%20in,the%20hot%20or%20cool%20tier.

You cannot directly read data from the Archive tier. When data is in the Archive tier, it's cold storage that is optimized for infrequent access, and to retrieve it, you need to perform a rehydrate operation. This involves restoring the data to a more accessible tier (like Hot or Cool) before you can read it. The question ask if you can read the files but note once a file is in Archive you can't read it until you rehydrate it.

Should the correct answer be the one provided? The Dept1File1.docx got edited on October 2 there for by the 10th it should still be able to be read. or am i wrong?

This question is valid as per 1st Oct, 2024

WRONG No Yes Yes

The answer is: No, Yes, Yes No - On October 10 you can not read the Dep1File1.docx file, because its being applied by Rule 1 only. Rule 1 says if blobs not modified for 2 days it will be moved to archive storage and needs to be re-hydrayed, which takes several hours. After 9 days its deleted, but its only 8 days old.. so no worries. -Yes on October 10, you can read File2.docx because rule #2 is applying to here - since it was last edited October 5, only 5 days have passed. After 3 days its moved to cool storage - and files in cool storage are readable! Yes - File3 is readable because it was last edited on October 2, which throws it in cool storage, and not enough time has passed for it to move to archive storage.

The reason I agree with given answer is because a prefix in a blob is like creating a vitrual directory structure in a blob container. So, when giving a prefix of Dep1/ it means that a vitrual folder gets created that blobs can get saved into. The question does not specify where the blobs get uploaded so I assume that they get uploaded to container1. Based on that, in order for rule1 to apply to any given blob, the blob would need to have a prefix of Dep1/. The first blob does not have said prefix, it's just that it's name starts with Dep1 which is different from the Dep1/ prefix that creates the folder. For the first question to be NO as everyone says, Dep1File1.txt blob would need to have a prefix of Dep1/ meaning, Dep1/Dep1File1.txt. Basically the only rule that applies here is rule2 and since every blob has a maximum modify date of 9 days we can access every blob. Correct answer is YYY

Taking the October 1 "Action" literally, the 3 files were uploaded to the Container not the folder /Dep1. Therefor on October 10 you would be able to read Dep1File1.docx. azcopy cp /path/to/local/file.txt: The path to your local file. [account]: Your Azure Storage account name. [container]: The name of the target container. [path/to/blob]: The desired path within the container (optional).

How can the answers for Dep1File1.doc.x and File3 be different, given that I don't see any difference in their lifecycle? They were both created in the same container on the same day and later modified again, but again on the same day. So why do so many people treat them as if they are in different containers or have something different? Or am I just missing something?

Given answer is right

I don't get why Dep1File1.docx and File3.docx where uploaded the same day (October 1st), edited the same day (Oct 2nd) and still one can be acceded and the other not on October 10 (Question 1 and 3), I think either both are archived or both are in cool storage, what am I missing?

The correct answer should ne NYY. https://learn.microsoft.com/en-us/azure/storage/blobs/archive-blob?tabs=azure-portal While a blob is in the archive tier, it can't be read or modified. To read or download a blob in the archive tier, you must first rehydrate it to an online tier, either hot or cool.

1. No. You can not read Dept1File.docx , YOu can not read file in archive tier 2. Yes. Because file is modified on 5 Oct, after 2 days it moved to cool storage and on 10th oct its still in cool storage. You can read file in cool storage. 3. Yes. Same as File 2 its still in cool storage, because its modified on 2nd oct it still has one day to move to archive tier.

This was on my exam, but the rule block was different.

N Y Y is 100% correct no need to further discuss this as: Dep1File1 is hit by rule 1 which will archive the file by the 10th rendering it unreadable
