Read the first 7 Certified Solutions Architect S3 Storage Classes and Policies flashcards as text
A company stores infrequently accessed compliance logs that must be retrievable within 12 hours. Which S3 storage class minimizes cost while meeting this requirement?
Answer: S3 Glacier Flexible Retrieval
S3 Glacier Flexible Retrieval offers bulk retrieval within 5-12 hours at the lowest cost for archives needing occasional access.
Which S3 feature automatically moves objects between storage classes based on configurable time-based rules?
Answer: S3 Lifecycle policies
S3 Lifecycle policies let you define rules that transition objects to cheaper storage classes or expire them after a set number of days.
An architect needs to store primary copies of objects with the lowest possible latency. The objects are accessed multiple times a day. Which storage class is most appropriate?
Answer: S3 Standard
S3 Standard is designed for frequently accessed data with millisecond latency and high throughput.
What is the minimum storage duration charge for objects stored in S3 Glacier Deep Archive?
Answer: 180 days
S3 Glacier Deep Archive has a minimum storage duration of 180 days; deleting objects earlier still incurs the full 180-day charge.
A lifecycle rule transitions objects from S3 Standard to S3 Standard-IA. What is the minimum age an object must be before it can be transitioned?
Answer: 30 days
AWS requires objects to remain in S3 Standard for at least 30 days before a lifecycle rule can transition them to S3 Standard-IA.
Which S3 storage class stores data in only a single Availability Zone and is best suited for easily re-creatable, infrequently accessed data?
Answer: S3 One Zone-IA
S3 One Zone-IA stores data in a single AZ, making it ~20% cheaper than Standard-IA but with lower durability guarantees.
An S3 bucket policy uses the condition key 's3:prefix' to restrict access. What does this condition evaluate?
Answer: The beginning of the object key name in the request
The s3:prefix condition key matches the leading characters of the requested object key, allowing path-based access control within a bucket.
