Topic 1 Question 22
A solutions architect is using Amazon S3 to design the storage architecture of a new digital media application. The media files must be resilient to the loss of an Availability Zone. Some files are accessed frequently while other files are rarely accessed in an unpredictable pattern. The solutions architect must minimize the costs of storing and retrieving the media files. Which storage option meets these requirements?
S3 Standard
S3 Intelligent-Tiering
S3 Standard-Infrequent Access (S3 Standard-IA)
S3 One Zone-Infrequent Access (S3 One Zone-IA)

"unpredictable pattern" - always go for Intelligent Tiering of S3 It also meets the resiliency requirement: "S3 Standard, S3 Intelligent-Tiering, S3 Standard-IA, S3 Glacier Instant Retrieval, S3 Glacier Flexible Retrieval, and S3 Glacier Deep Archive redundantly store objects on multiple devices across a minimum of three Availability Zones in an AWS Region" https://docs.aws.amazon.com/AmazonS3/latest/userguide/DataDurability.html

The storage option that meets these requirements is B: S3 Intelligent-Tiering.
Amazon S3 Intelligent Tiering is a storage class that automatically moves data to the most cost-effective storage tier based on access patterns. It can store objects in two access tiers: the frequent access tier and the infrequent access tier. The frequent access tier is optimized for frequently accessed objects and is charged at the same rate as S3 Standard. The infrequent access tier is optimized for objects that are not accessed frequently and are charged at a lower rate than S3 Standard.
S3 Intelligent Tiering is a good choice for storing media files that are accessed frequently and infrequently in an unpredictable pattern because it automatically moves data to the most cost-effective storage tier based on access patterns, minimizing storage and retrieval costs. It is also resilient to the loss of an Availability Zone because it stores objects in multiple Availability Zones within a region.

Keywords:
- Must be resilient to the loss of an Availability Zone.
- files are accessed FREQUENTLY while other files are RARELY accessed in an UNPREDICTABLE pattern.
A - Incorrect: S3 Standard is not cost effective for rarely access files B - Correct: S3 Intelligent-Tiering is good for file which frequently or rarely accessed in an unpredictable pattern. Intelligent-Tiering will help us analyze the pattern and move rarely access files to storage which has lower cost. C - Incorrect: Standard-Infrequent Access is not cost effective for frequently access files D - Incorrect: One Zone-Infrequent Access is not resilient to the loss of an Availability Zone
