A Lifecycle rule moves objects to S3 Glacier Deep Archive, but the physical transition happens after the rule becomes eligible. When do the destination-class rate and minimum-duration clock begin?
- A
Charges begin only after the object has physically completed its transition.
- B
The minimum-duration clock starts when the object is first read in the destination class.
- C
The destination-class rate and minimum-duration clock start when the rule becomes eligible.
- D
Lifecycle transitions have no charges if they happen asynchronously.
For each object in S3 Glacier Flexible Retrieval or Deep Archive, the metadata overhead is , of which is billed at the archive-class rate.
A recovery plan uses S3 Glacier Deep Archive. Which statements about its retrieval options are accurate? Select all that apply.
- A
Standard retrieval is typically within 12 hours.
- B
Expedited retrieval is typically available in 1–5 minutes.
- C
Bulk retrieval is typically within 48 hours.
- D
Expedited retrieval is not available.
An application restores an object from S3 Glacier Flexible Retrieval. Which statements describe what happens to the object and its restored copy? Select all that apply.
- A
The restore permanently moves the original object to S3 Standard.
- B
The restore creates a temporary readable copy that expires after the requested number of days.
- C
The original object is deleted as soon as the temporary copy is created.
- D
To keep data readily accessible, the restored object can be copied to another S3 storage class.
A team has an object in S3 Glacier Flexible Retrieval and can wait several hours. Which retrieval tier is free for this class?
- A
Expedited
- B
Bulk
- C
Standard
- D
Deep Archive Standard
A research institute must retain historical records for many years. It expects to consult them rarely and can wait hours when recovery is needed. Recommend the most suitable S3 Glacier class and explain why it fits, including at least one important access or storage-duration trade-off.
What S3 request method retrieves an object stored in S3 Glacier Instant Retrieval?
How much total metadata overhead is added per object in S3 Glacier Flexible Retrieval and Deep Archive? Enter the number of kilobytes.
True or false: For a Lifecycle transition to S3 Glacier Flexible Retrieval or Deep Archive, destination-class charges and the minimum-duration clock begin only after the physical transition is complete.
- A
True
- B
False
An organization wants a Lifecycle rule to transition only records carrying a particular archival tag, while leaving other bucket objects unchanged. Which approach fits this requirement?
- A
Create a separate AWS Region for the records.
- B
Use a Lifecycle rule filtered by the records' tag.
- C
Wait until each object has been restored.
- D
Change the storage class of every object in the bucket.
A 90 KB object matches the age and tag filters in an S3 Lifecycle rule that transitions objects to an archival class. What happens by default?
- A
It transitions automatically because all objects are eligible.
- B
It transitions only if it is accessed frequently.
- C
It does not transition by default because it is smaller than 128 KB.
- D
It transitions only after the object is restored.
