Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C03

Question #: 49
Topic #: 1

[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A company stores call transcript files on a monthly basis. Users access the files randomly within 1 year of the call, but users access the files infrequently after 1 year. The company wants to optimize its solution by giving users the ability to query and retrieve files that are less than 1-year-old as quickly as possible. A delay in retrieving older files is acceptable.
Which solution will meet these requirements MOST cost-effectively?

A. Store individual files with tags in Amazon S3 Glacier Instant Retrieval. Query the tags to retrieve the files from S3 Glacier Instant Retrieval.
B. Store individual files in Amazon S3 Intelligent-Tiering. Use S3 Lifecycle policies to move the files to S3 Glacier Flexible Retrieval after 1 year. Query and retrieve the files that are in Amazon S3 by using Amazon Athena. Query and retrieve the files that are in S3 Glacier by using S3 Glacier Select.
C. Store individual files with tags in Amazon S3 Standard storage. Store search metadata for each archive in Amazon S3 Standard storage. Use S3 Lifecycle policies to move the files to S3 Glacier Instant Retrieval after 1 year. Query and retrieve the files by searching for metadata from Amazon S3.
D. Store individual files in Amazon S3 Standard storage. Use S3 Lifecycle policies to move the files to S3 Glacier Deep Archive after 1 year. Store search metadata in Amazon RDS. Query the files from Amazon RDS. Retrieve the files from S3 Glacier Deep Archive.

Selected Answer: B

I think the answer is B: Users access the files randomly S3 Intelligent-Tiering is the ideal storage class for data with unknown, changing, or unpredictable access patterns, independent of object size or retention period. You can use S3 Intelligent-Tiering as the default storage class for virtually any workload, especially data lakes, data analytics, new applications, and user-generated content. https://aws.amazon.com/fr/s3/storage-classes/intelligent-tiering/

Agree, S3 Intelligent-Tiering meets all the requirements. The very important/crucial consideration here to satisfy that all files withing a year are instantly accessible is that the two options "Archive Access" and "Deep Archive Access" are not enabled in the "Archive rule actions" section present in the "Intelligent-Tiering Archive configurations" of the bucket. Those options are not enabled by default so this answer will work.

What about if the file you have not accessed 360 days and intelligent tier moved the file to Glacier and on 364 day you want to access the file instantly ? I think C is right choice

It says "S3 Intelligent-Tiering is the ideal storage class for data with unknown, changing, or unpredictable access patterns". However, the statement says access pattern is predictable. It says there is frequent access about 1year.

Answer is C, why not intelligent Tiering If the Intelligent-Tiering data transitions to Glacier after 180 days instead of 1 year, it would still be a cost-effective solution that meets the requirements. With files stored in Amazon S3 Intelligent-Tiering, the data is automatically moved to the appropriate storage class based on its access patterns. In this case, if the data transitions to Glacier after 180 days, it means that files that are infrequently accessed beyond the initial 180 days will be stored in Glacier, which is a lower-cost storage option compared to S3 Standard.

C involves moving "the files to S3 Glacier Instant Retrieval" which is not cost-effective since "a delay in retrieving older files is acceptable."

With S3 Intelligent-Tiering, you can define rules that determine when objects should be moved from the frequent access tier to the infrequent access tier, or vice versa, within S3 Standard storage classes.

The Answer is B. S3 Intelligent-Tiering stores objects in two access tiers: one tier that is optimized for frequent access and another lower-cost tier that is optimized for infrequent access. For a small monthly monitoring and automation fee per object, S3 Intelligent-Tiering monitors access patterns and moves objects that have not been accessed for 30 consecutive days to the infrequent access tier. There are no retrieval fees in S3 Intelligent-Tiering. If an object in the infrequent access tier is accessed later, it is automatically moved back to the frequent access tier. No additional tiering fees apply when objects are moved between access tiers within the S3 Intelligent-Tiering storage class. S3 Intelligent-Tiering is designed for 99.9% availability and 99.999999999% durability, and offers the same low latency and high throughput performance of S3 Standard

Option B provides cost optimization, query capability, and low-latency access for recent files, with acceptable latency for older data, all with minimal operational effort—making it the best choice for this use case.

Selected Answer: B

Why Option B Works Best: First Year (Active Access): S3 Intelligent-Tiering automatically shifts objects between Frequent and Infrequent Access tiers, reducing costs by ~40% if access declines. Athena queries data directly in S3, avoiding retrieval fees for active tiers. After 1 Year (Infrequent Access): Lifecycle policies transition data to Glacier Flexible Retrieval, which supports Glacier Select for SQL-based partial retrievals (avoids restoring entire files). Cost savings: Flexible Retrieval is cheaper than S3 Standard-IA and allows expedited (1–5 min) or bulk (5–12 hr) retrievals. Query Flexibility: Recent files (<1 year) are queried via Athena with millisecond latency. Older files (>1 year) use Glacier Select to retrieve subsets of data, minimizing retrieval costs and time.

Selected Answer: B

Option A Incorrect – S3 Glacier Instant Retrieval is more expensive than necessary for frequently accessed files, and tag-based querying is inefficient. Option C Incorrect – Using S3 Glacier Instant Retrieval after 1 year is more expensive than needed, and storing metadata in S3 is less efficient than Athena. Option D Incorrect – S3 Glacier Deep Archive has long retrieval times, and maintaining metadata in RDS adds extra costs. Option B Correct – S3 Intelligent-Tiering optimizes costs, and S3 Glacier Flexible Retrieval balances cost with acceptable retrieval delays, while Athena and S3 Glacier Select enable efficient queries.

Selected Answer: B

The B and C are both good options, but since Athena is free for use with S3, it definitely the B-option. Athena queries data directly from Amazon S3. There are no additional storage charges for querying your data with Athena.

Selected Answer: C

This solution best meets the requirements while being cost-effective because: 1. **Initial storage in S3 Standard:** Provides the fastest access for files less than 1 year old, meeting the requirement for quick retrieval of newer files 2. **Metadata storage in S3 Standard:** Enables efficient querying and searching of files without additional database costs 3. **Lifecycle policy to S3 Glacier Instant Retrieval:** Provides cost optimization for older files while still maintaining relatively quick retrieval when needed.

If you are like me and thought Athena would make this cost-inefficient: Athena is free for s3 querying. It has a cost per TB for SQL Queries. And a different cost for Apache apps. https://aws.amazon.com/athena/pricing/

Answer is C. The only difference between choice B and C is Glacier Storage class. The question states clearly that "giving users the ability to query and retrieve files that are less than 1-year-old as quickly as possible". This is possible via instant retrieval and not flexible retrieval.
