Exam AZ-104 topic 3 question 15 discussion

Actual exam question from Microsoft's AZ-104
Question #: 15
Topic #: 3
[All AZ-104 Questions]

You have an Azure subscription that contains the storage accounts shown in the following table.

You need to identify which storage account can be converted to zone-redundant storage (ZRS) replication by requesting a live migration from Azure support.
What should you identify?

  • A. storage1
  • B. storage2
  • C. storage3
  • D. storage4
Show Suggested Answer Hide Answer
Suggested Answer: B 🗳️
ZRS currently supports standard general-purpose v2, FileStorage and BlockBlobStorage storage account types.
Incorrect Answers:
A, not C: Live migration is supported only for storage accounts that use LRS replication. If your account uses GRS or RA-GRS, then you need to first change your account's replication type to LRS before proceeding. This intermediary step removes the secondary endpoint provided by GRS/RA-GRS.
Also, only standard storage account types support live migration. Premium storage accounts must be migrated manually.
D: ZRS currently supports standard general-purpose v2, FileStorage and BlockBlobStorage storage account types.

This is one of those ridiculous questions that would imply we should memorize the 50 different combinations of storage type, replication type, versus live migration support. Useless info to keep in your head, why would they test for this. The support rules around live migration support are horrendous. Bleh.

Complain here is useless. And from your point of view, all certificate exams should be ridiculous. Back to the question, answer B is correct. "Live migration is supported only for storage accounts that use LRS or GRS replication. If your account uses RA-GRS, then you need to first change your account's replication type to either LRS or GRS before proceeding. This intermediary step removes the secondary read-only endpoint provided by RA-GRS before migration." "ZRS supports general-purpose v2 accounts only"

Answer is correct. It is storage2. The key to the answer in this question is "Live migration" - You can do Live migration to ZRS from LRS or GRS only. - Also this only applies on General Purpose v2 storage.

Live migration is supported only for storage accounts that use LRS or GRS replication. If your account uses RA-GRS, then you need to first change your account's replication type to either LRS or GRS before proceeding. This intermediary step removes the secondary read-only endpoint provided by RA-GRS before migration. ZRS supports general-purpose v2 accounts only. You can request live migration through the Azure Support portal.

Selected Answer: B
storage1 -> NO, because the “(Standard) general purpose v1” does not support ZRS … I’ve put “Standard” in parenthesis because the documentation I’ve found do not mention about *premium* general purpose v1, but since it is not specified I suppose the same limitations apply to it. storage2 -> YES : the migration from LRS to ZRS is supported, and excluding the other options only this one remains. storage3 -> NO : the conversion from “…from GRS/RA-GRS” requires “Switch to LRS first”. storage4 -> NO: the “BlobStorage” kind, is a “Legacy blob storage” that does not support ZRS.

Since ZRS is only supported by StorageV2 only B and C would apply. Live migration is not possible for RA-GRS (option C). Option B remains.
