Exam question from Amazon's AWS-SysOps

Question #: 289
Topic #: 1

A user has moved an object to Glacier using the life cycle rules. The user requests to restore the archive after 6 months. When the restore request is completed the user accesses that archive. Which of the below mentioned statements is not true in this condition?

A. The archive will be available as an object for the duration specified by the user during the restoration request
B. The restored object's storage class will be RRS
C. The user can modify the restoration period only by issuing a new restore request with the updated period
D. The user needs to pay storage for both RRS (restored) and Glacier (Archive. Rates)

Show Suggested Answer

Suggested Answer: B 🗳️
AWS Glacier is an archival service offered by AWS. AWS S3 provides lifecycle rules to archive and restore objects from S3 to Glacier. Once the object is archived their storage class will change to Glacier. If the user sends a request for restore, the storage class will still be Glacier for the restored object. The user will be paying for both the archived copy as well as for the restored object. The object is available only for the duration specified in the restore request and if the user wants to modify that period, he has to raise another restore request with the updated duration.

Selected Answer: B

In the given scenario, when an object is restored from Glacier using a restore request, the restored object's storage class will not be Reduced Redundancy Storage (RRS). The storage class of the restored object will be the same as the original object, which in this case would be Glacier.

C You can restore an object copy for any number of days. However you should restore objects only for the duration that you need because of the storage costs associated with the object copy. When you restore an archive, you pay for both the archive (at the S3 Glacier or S3 Glacier Deep Archive rate) and a copy that you restored temporarily (Reduced Redundancy Storage (RRS) or Standard, whichever is the lower cost storage in the region).

The question is asking for what is NOT true. C is true because when you request a retrieval, you specify how long your object will be retained in either RRR or Standard storage.

B is correct. After you receive a temporary copy of the restored object, the object's storage class remains S3 Glacier or S3 Glacier Deep Archive. (A HEAD Object or the GET Object API operations request returns S3 Glacier or S3 Glacier Deep Archive as the storage class.) https://docs.aws.amazon.com/AmazonS3/latest/dev/restoring-objects.html

I think the answer is A, the archive itself will not change attribute to object, the archive will be copied to another storage tier as object.

Comparing B & D, Does anyone can confirm , after retrieving the data from Glacier, where it will restore ?

Depending on which is cheaper in your region, your retrieved objects are restored in RRR or Standard.

B & D are both wrong. The storage class does not change. Think question is wrong. I feel like all four is true.
